CQ WW DX: CATEGORIA "EXTREME"

2009-06-19T09:36:00.000-03:00

Una Nueva Categoría "Extrema" está siendo agregada al concurso CQ WW DX para fomentar el desarrollo de nuevas tecnologías en las comunicaciones de radioaficionados en general y en los concursos en particular. De acuerdo con el director del CQ WW, Bob Cox, K3EST, esta nueva categoría ha sido establecida para permitir a los aficionados participar en el CW WW mientras experimentan creativamente con estaciones vinculadas por internet y otras tecnologías nuevas no permitidas en ninguna de las demás categorías. Las reglas de la categoría "Extrema" tal cual han sido aprobadas por el comite del CQ WW, siguen a continuación, junto con una detallada explicación de como se funcionará el sistema de puntajes. Esta nueva categoría será efectiva en el concurso CQ WW de 2009 a desarrollarse más adelante este año.

REGLAS PARA LA CATEGORIA "EXTREME" del CONCURSO CQ WW

Panorama General

Una amplia gama de tecnologías han emergido en la radioafición, incluyendo radios definidas por software, estaciones remotas, sitios para recepción conectados por internet, decodificadores de CW multi canal, estaciones "robot" completamente automatizadas, etc. Algunas de estas tecnologías no están actualmente permitidas bajo las reglas del CQ WW DX Contest para las categorías existentes.

Por ejemplo, las reglas del CQ WW establecen lo siguiente:

"Todos los transmisores y receptores utilizados por el participante deben estar ubicados en un único círculo de 500 metros de diámetro, o dentro de los límites de la propiedad del titular de la licencia si esta es más extensa"

N de la T: Tengo alguna duda sobre la traducción de este párrafo. "..whichever is greater"...se puede interpretar de dos formas completamente distintas. Utilicé el criterio usado en las reglas publicadas por los editores de la revista CQ Española.

"Todas las antenas deben estar físicamente conectadas a los transmisores y receptores utilizados por el participante".

Esta nueva categoría se ha establecido, para permitirle a los aficionados participar en el concurso CQ WW mientras experimentan creativamente con estaciones vinculadas por internet y otras nuevas tecnologías.

Las reglas del concurso CQ WW DX aplican en todo lo referente a duración del concurso, intercambios, y puntaje. Además de las reglas básicas, la categoría extrema incluye lo siguiente:

1. Categorías de participación: (a) Mono-Operador, en la cual un radioaficionado con licencia sirve como operador de control, llevando a cabo o supervisando todas las actividades de operación y registro de QSOs. , y, (b) Multi-Operador, en la cual varios operadores llevan a cabo la supervisión de la operación y registro de contactos. En la categoría multi-operador los mismo pueden estar ubicados en distintas locaciones. Un mono operador puede remitir varias logs (planillas) utilizando distintos sitios remotos en diferentes países. Cada planilla será clasificada en forma separada.

2. Assitencia de Alerta para QSOs: La assistencia de alerta para QSOs utilizando packet-radio, internet, artefactos tipo skimmer locales o remotos, etc., está permitida tanto para mono operadores como para multi operadores. El auto spoteo o el requerimiento de ser spoteados no está permitido.

3. Locaciones: Los sitios de transmision del participante deben estar ubicados en un mismo país. Tal como lo defina la autoridad que autoriza la licencia y dentro de una misma zona (no aclara si zona CQ, ITU o qué tipo de zona). Las estaciones remotas para recepción pueden estar ubicadas en cualquier parte.

4. Transmisiones: Sólo se permite transmitir UNA SEÑAL en una misma banda al mismo tiempo. El ancho de banda máximo no debe exceder el ancho de banda normal de una unica señal de SSB voz (durante el fin de semana de SSB) o de CW (durante el fin de semana de CW). Esto prohibe la utilización de señales multi-carriers o multiplexadas por tiempo que ocupan varios canales en una misma banda.

5. Notificación anticipada: Los participantes deberán notificar al comité del CQ WW DX Contest por email al menos con una semana de anticipación sobre su intención de participar en esta categoría. Esta notificación debe incluir una breve descripción de las tecnologías y la señal distintiva a utilizar. Los participantes deben dar testimonio de que la operación que planean llevar a cabo cumple con las regulaciones del país donde el/los transmisor/es están ubicados. Notificaciones anticipadas y preguntas referente a estas reglas deben ser enviadas por email a xtreme@cqww.com

6. Operadores de control: Es responsabilidad de los operadores de control humanos que sea han tomado las precauciones necesarias antes de transmitir. Como por ejemplo escuchar si una frecuencia está o no ocupada antes de llamar CQ. Cualquier estación que se encuentre generando interferencia por no obedecer esta regla será pasiva de descalificación.

7. Envío de Planillas (logs): Los logs deben ser enviados por email a las direcciones habituales. ( or ). Los logs deben estar en formato cabrillo e incluir la linea CATEGORY: SINGLE-OP-XTREME or CATEGORY:MULTI-OP-XTREME, según se trate de mono o multi operador.

8. Puntaje: Los puntajes serán evaluados en dos dimensiones: puntaje e innovación. Para el primero un puntaje normal será computado en base a las estaciones trabajadas y a los multiplicadores de zona y país comunicados. Se requiere un mínimo de 100 QSOs. El log será evaluado con el mismo software que se utiliza para el resto de los participantes y las penalizaciones serán las mismas. La segunda parte del puntaje resultará de evaluar la innovación tecnológica utilizada por el participante. Esta evaluación será llevada a cabo por un panel de jueces del comité del concurso CQ WW. En caso de empate, el log con la menor reducción de puntaje luego del proceso de verificación de planillas será declarado ganador.

9. Diplomas: Los ganadores de las categorías mono y multi operador recibirán una placa.

10. Puntajes para Clubes: Las planillas de estaciones participando en esta categoría pueden contribuir con su puntaje al de su Club/Grupo, de acuerdo a las reglas de la competición por clubes. Las estaciones remotas fuera del area del club pueden contar como DX-peditions.

The Sunspots Mistery!....

2009-06-18T18:49:00.003-03:00

June 17, 2009: The sun is in the pits of a century-class solar minimum, and sunspots have been puzzlingly scarce for more than two years. Now, for the first time, solar physicists might understand why. At an American Astronomical Society press conference today in Boulder, Colorado, researchers announced that a jet stream deep inside the sun is migrating slower than usual through the star's interior, giving rise to the current lack of sunspots. Rachel Howe and Frank Hill of the National Solar Observatory (NSO) in Tucson, Arizona, used a technique called helioseismology to detect and track the jet stream down to depths of 7,000 km below the surface of the sun.

The sun generates new jet streams near its poles every 11 years, they explained to a room full of reporters and fellow scientists. The streams migrate slowly from the poles to the equator and when a jet stream reaches the critical latitude of 22 degrees, new-cycle sunspots begin to appear.

2009 ARRL DX CW @ ZW5B

2009-06-18T18:45:00.001-03:00

Wow!!! Being here at ZW5B was the most shocking experience in my contesting life!!! Everything was just wonderful. People, place, station, food, hospitality! Everything. Originally planned to enter SOAB, but I found Thomas PY2ZXU was here at the station so I thought it was great to invite him to stay with me and do two single band entries. That we did! We had lots of fun. I learned a lot here. Thomas simply rules!!! Another highlight was the visit to Don's (PY5ZBU) station. Don is devoted to EME mostly and having the opportunity of meeting a world class EME station and operator was very impressing.

Propagation was down from last year I guess. Trans-ecuatorial had somec effect here on 15 too when sunspots are down. So it was kind of strange to listen to southern stations run big piles while here the band was almost closed.

I must thank Oms PY5EG for letting this dream of mine come true! His passion for our hobby is all around this beautiful station. What he does to encourage new people to join this beautiful hobby can be touched with your hands and can be seen in everybody here willing to help with a truly fantastic team spirit!

I must thank also to PY2ZXU's XYL Laura for allowing Thomas to stay and operate and for all the nice chats we had about life in general.

Thanks Thomas for being such a super fantastic mate! I only hope we can share more contests in the future. Thanks Luciano PY5KD for all his help prior to the contest. Thanks Maia PY5CA for all his kind help and hospitality.

Thanks also to Sonia, and all the people here at the house for being just great and for making me feel like at home all weekend long!

Thanks again from heart!

ZW5B - 2009 ARRL DX CW CONTEST - DIARY

Thursday, Feb 19th 2009. Arrived in Sao Jose Dos Pinhais Airport (Curitiba) at 23:30 GMT. It was already dark and I directly headed for PY5EG's station. At the house I first met Maia PY5CA who was there waiting for me. We went to the shack where he was tuning 40 m running a big pile up of European stations. He invited me to operate SSB for a while. The pile up was tremendous! It was hard to pick a single letter out of the pile.

After a while Maia told me that Thomas SM0CXU (PY2ZXU) of HZ1AB fame was there at the station working on the 80 m 3el Yagi. I spent half an hour looking at the countless WAEDC, CQ WW, ARRL DX contests plaques won from ZW5B whilst Maia was updating me on the station description.

The stations is build around several towers for assorted monoband yagis and yagi arrays. The 80 m 3 el yagi was down at ground level being modified for improved performance. Very nice mods indeed using W6ANR-type high unloaded Q coils. Much better directivity pattern and gain than with linear loaded elements.

After an hour or so at PY5EG's I found Thomas whom I first met at WRTC 2006 in Florianopolis. I asked him to stay so we could make two single band efforts from the station. He and his XYL Laura invited me out to have dinner. During dinner we decided to enter 40 m (Thomas) and 15 m (me).

After a couple of delicious pizzas and good conversation we returned to the station. I spent some time making QSOs on 40 and then went to bed.

Friday, Feb 20th 2009. I got up early in the morning we had breakfast with Thomas, Laura and Maia. Then we went where the 80 m antenna was and we kept working on the antenna till noon. I was glad I was allowed to help. This was the first big 80 m yagi I had the opportunity to see at ground level. It's a very impressive and big antenna. After a while we took a break and we headed for the shack where we called Oms on the phone. We talked about our plans for the contest and he was happy we were going to enter in two different bands. We got back to the 80 m yagi and worked till lunch.

After lunch we headed for PY5ZBU's station about an hour and a half away from PY5EG's. Don is devoted to EME and we enjoyed our visit very much. Thomas took an FT 1000 MP for Don to check on the front end performance. We talked about Don's EME activities and I was there listening amazed at all the knowledge and passion he was sharing with us.

Don built a full fledge EME stations. He was the first to claim DXCC via EME. In his professional carrer he conducted part of the IRIDIUM satellite phone system among other major projects. Part of his equipments is home made in a totally professional way. You can see transverted Collins for use in either 432 Mhz and 1.2 Ghz. Yaesu FT-736, Kachina, etc, etc. Don's station is a unique place to be for all those who love EME communications. Around 21 GMT we finished our visit thanking Don for such a great opportunity of meeting a world class EME station.

We got to the station around 23 Z. Just an hour or so before the contests tarted. Thomas spent some time hooking up his computer. I kept warming up on 15 meters. 21 Mhz already sounded punk even b4 the contest started. But I felt really happy doing single band. ZW5B is a big station so you better go there a couple of times before doing an all band effort.

Saturday, Feb 21st 00 GMT. Thomas had a great start on 40 m. My first hour on 15 m was really slow netting only 62 Qs. At 02Z I went to bed because the band was completely dead. I actually kept sending CQs till 03z but no takers at all. I woke up at 9 Z and the band was dead send several CQs for about 30 mins. Thomas was working Ws on 40 at a really good pace.

15 started to open at 12 Z only 4 Qs were worked. Best two hours were 14 and 15 z totalizing 146 Qs each. They rest of the day was slow reaching the half way mark with 1101 Qs. Signals were really unreadable at time and some Qs required many repeats.

Thanks everyone for the patience! I experienced the same deep QSB several times on 15 and 10 m during the past few sunspots-less years.

Sunday, Feb 22nd. It was even harder than Saturday. Signals were even down at RCVR noise floor levels. Both Thomas and I finished the contest at 10 pm local time. We talked a lot before, during and after the contest.

On Monday. Thomas drove me to the airport and spent a couple of hours talking about our hobby and about our lives.

I'll never forget this weekend. It was a dream come true for several reasons:

I was able to experience the unsurpassed Hospitality, Friendship and Team Spirit of all the people involved with the Araucaria DX Group. I believe that's Oms's biggest achievement: The group of people he encouraged and got involved in our beautiful hobby is just fantastic. I also had the opportunity of spending a weekend with one of the ops I admire since I started contesting in 1988. At that time Thomas (SM0CxU/PY2ZXU) was active from HZ1AB in every possible contest. Thomas was also one of the hard working friends who made possible WRTC2006.

I was able to operate from ZW5B. A unique station, a unique place and unique friendly people.

I met Don PY5ZBU and visited his world class EME station.

I met Luciano PY5KD and Maia PY5CA to great friends who really helped us lot.

I believe there are now words to express how happy I was. I only can say thanks from heart to Oms, Thomas, Maia, Luciano, Sonia, Laura and all the people at ZW5B.

Comments:

It was a last minute arrangement because original plan was to join ZW5B Multi
Multi operation, but job schedule prevented me from traveling to PY5EG's. BTW
Thanks a lot to Oms, Maia, Luciano, Thomas and the rest of the ops for the
invite. They did a super job in Multi Multi with really bad propagation from SA
to EU/USA on most HF bands.

: Rigs/Rotator Cobtrol Boxes/Antenna Switch 5x2

Deep heart thanks to Ramon LU5HM and his family for their support and
hospitality. Second time around using LP1H's fully functional SO2R set up.

Ramon spent the whole contest sitting right next to me to overcome the lack of
propagation with long talks about our hobby and life in general.

Thanks also to LU7HE for all his hard work at the station. Both linear amps
used were built by LU7HE. Though they are home made they are built in a very
professional way.

Ramon's mother was there all weekend long too, making sure we always had
something to eat/drink.

Javier LU9HS was at the station all Saturday afternoon making good company. He
also went there the previous weekend to make sure everything was in place for
my operation.

Thanks also to Juan LU3HY for advice on N1MM not getting spots (it was not N1MM
fault though, it was AB5K being clunky).

Thanks to all of you for the Qs. I apologize for asking for so many repeats,
but there were times when stations calling would just disapear in the deep
QSB.

Regards.

2008 WAEDC CW @ LR4E

2009-06-18T18:38:00.001-03:00

Qué lindo contest!!!!!!!!!!!!!!!! El WAE es un concurso como el IARU, por ahí uno no participa seguido pero el formato del concurso es excelente. En este caso sólo 36 horas, lo cual viene al pelo para los que ya no nos cocinamos en el primer hervor.
Otra vez tuve la oportunidad de visitar a Geo, LW4EU quien como siempre me hizo sentir en mi propia casa durante todo el fin de semana.
Llegué a Chacabuco a las 8 de la mañana y partimos hacia el campo donde Jorge tiene la estación. El día realmente estaba espectacular y bastante frío. En Luján al salir la temperatura era de un grado bajo cero, pero en la estación meteorológica del campo la temperatura mínima registrada durante la noche había sido 5 bajo cero!

Al llegar desayunamos con unas facturas y fuimos al shack a pegar una revisada a todo. Todo estaba en orden y listo para empezar el concurso. Había un problemita con la JVP y la ROE en 20,15 y 10 era alta, pero no impedía que hicieramos el concurso. En 20 mts a las 10:30 hora local se escuchaban EUs bastante bien.

Al mediodía almorzamos un expectacular asado y luego como a las 14 hs,me fuí a dormir una siesta que duró hasta las 19. Al despertarme lo llamé a Lucas, LU1FAM pero no lo podía ubicar. Pensando que estaban en LT1F lo llamé a Carlos LU1FKR para ver cómo andaba todo, pero Carlos me dijo que no iban a hacer el concurso.
Al levantarme le comenté a Geo que antes de ir a descansar había estado haciendo unos QSOs y el ACOM se ponía en Stand By, por la diferncia de tensión, dado que la entrada de la fuente estaba para 240, así que sacamos la tapa del ACOM, le sacamos el trafo y corrimos los dos primeros jumpers hacia la derecha para ponerlo en 220. Esa operación duró unos 20 minutos, pero fué lindo ver el ACOM por dentro!!!!!!!!!!

El concurso empezó en 40 metros con un ritmo bastante lento, pero era lo que había. Mi idea era hacer 1000 comunicados aproximadamente. No me deseperé para nada al ver el ritmo que llevabamos en esas primeras horas porque sabía que iba a ser largo el concurso y generalmente cuando el caudal de comunicados es bajo uno tiende a dispersarse o dormirse!!!!!

Al ir a 80 metros pude ver que la banda estaba muy silenciosa, es decir no había ruidos de tormenta ni nada por el estilo. A eso de las 2 de la mañana decidí ir a dormir para tomar parte del descanso. A pesar de haber dormido como 4 horas antes del concurso tenía mucho mucho sueño.

El concurso lo hice enteramente con la bencher y el manipulador del FT1000MP. Desde los CQ hasta los QTC, dado que la notebook se quedaba "pegada" y solo emitía un tono, o bien la manipulación se entrecortaba. El manipulador del 1000 es muy fiel y no falló para nada, las chingadas corren por mi cuenta!! :-)

Antes de ir a dormir comí unas empanadas riquísimas que había hecho Ana la esposa de Jorge. Panza llena corzón contento y mucho cansancio de una semana agetreada así que puse el despertador para no quedarme dormido. A las 9 UTC me desperté y se escuchában EUs bajos, paso corto. Los llamaba y nada así que esperé hasta las 10:50 UTC cuando la banda ya sonaba mejor.

Al pasar a 15 mts aprecié que la situación no iba a ser favorable para nosotros aquí en Sudamérica. Veía que los americanos spoteaban EUs en 21 e incluso algunos en 28. Por lo cual la escasa propagación en 21 Mhz hacia EU sumado a las antenas netamente de costado hicieron que salvo excepciones la mayoría llegara con muy bajas señales.

En 10 metros hubo algo de actividad. En un momento paso a un par de estaciones que me habían llamado y les pido QSO en 10. Llamaba y llamaba y no pasaba nada, pero en un momento veo que lo spotean a Javi que estaba como LQ0F y ahí pasé a 10 mts, con una mini apertura que se prolongó por una hora y media aproximadamete. Con mejores señales obviamente, dado que los Europeos a esa hora tenían sus antenas para el SUR!! Me pasó el domingo que domingo que una estación me solicita QTC llegaba a nivel de ruido, le contesto: SRI QSB. Y ahí me dice QRX y giró la antena! la diferencia fue notable obviamente.

Me sirvió mucho el hecho del ritmo lento para hacer comparativas de recepción con otras estaciones. En los momentos en los que no había ruido se podía escuchar de una manera espectacular. En un momento había un ruido intermitente S1 que enmascaraba las estaciones, pero girando la antena al ESTE desaparecía y podía escuchar, aunque mi señal seguramente bajaba en EU, era más productivo que tratar de escuchar los EU a través del ruido eléctrico.

EL FT 1000 con los 2 filtros nuevos uno de 400 hz y otro de 250 hz un espectáculo. Con 250 se puede trabajar muy cómodo en bandas super congestionadas.

La apertura de 20 la segunda tarde fué bastante corta y 40 y 80 mts fueron las bandas a utilizar hasta la 4:30 UTC hora en la que me fuí nuevamente a descansar.

Tomaba como parámetro los Qs que llevaba Jorge CX6VM, al finalizar la primera noche en el momento en que corté la transmisión teníamos una diferencia de 5 QSOs. Lo cual me puso contento porque la performance era óptima en el sentido de que era la estación que había hecho mejor puntaje en el WPX CW desde nuestra zona y para este contest era mi punto de referencia. Si bien no sabía cuántas horas había descansado Geo la primera noche, suponía que era más o menos lo que había descansado yo.

La mañana del domingo obviamente se presentó más lenta que la del sábado, con señales más bajas y menos ruido también. Seguí haciendo comparativas de recepción con respecto a CX6VM, LS1D y LU7HN. Me impresionó realmente la performance en recepción de LU7HN y también Jorge por su puesto. Son estaciones que escuchan de forma muy eficiente.

El segundo día sólo se hicieron 300 QSO! Y la diferencia que mantenía con respecto a Jorge se amplió a casi 200 Qs. Realmente va a ser un concurso muy entretenido de aquí a 3 o 4 años cuando el ciclo solar esté llegando a tope. Si es que no tenemos un período de 80 o 90 años sin alta activiad solar ;-)

Quiero felicitar a todos los que participaron. En especial a Jorge CX6VM. A Javi, LQ0F (LU5FF) por su excelente performance en Low Power y también a LU7HN por su puntaje.

73!

Fab, DJ1YFK @ 150 - 200 WPM

2008-05-05T09:51:00.004-03:00

Yes, can you believe that? 200 wpm -words per minute - Morse Code. There are just a few guys in the world that can copy at that speed, one of them is my good friend Fab, DJ1YFK. He is in the top list of hte RUFZxp permanent ultra high speed Morse Code contest. www.rufzxp.net . He is also top in the standings of the Bavarian Contest Club High Speed CW competition using the contest simulator by JE3MAS.
I bet you won't copy a single bit of what's he is doing in the videos, but anyway it's amazin to see how he performs!!!

In this first video he copies JA7MEH at 1000 CPM, that is 200 WPM based on the PARIS meassure system. He copied the call on the first try!

Here Several calls at 150 + WPM!!!

Hey everybody!We enjoyed another excellent weekend at LT1F!! Meeting Mario LW8DQ and Horacio LW7DX two ops at LR2F at Rosario's bus station was our first surprise. It was around 6 am in the morning and after chatting for a while with them we headed to LT1F with Karl, LU1FKR .One our way to the antenna farm we stopped by Jose's LU1FJto get our backup rig an IC756. When you are arriving at LT1F you start remembering wonderful moments spent along with good friends what is always a priority for us all. After we parked our cars, we checked rotarors and antennas and everything was ok. After awhile we started hooking up the radios and amplifiers. Our main station was anIC775DSP + L4B and our multiplier station was an IC756 + TL922, with two networked PCs. We tested all the antennas except for our 2 El delta loop for 80 and our 160Slooper. After we connected our 80 antenna we realized that something was wrong.The 75 ohms feed line wasn't working and after 30 minutes Karl LU1FKR solved ourfirst issue. All antennas were working fine, so it was time to verify all computers were working ok Lucas's notebookwasn't working properly when we tried to load N1MM but after a fast deletion of internet temporary files (1.5gbs) it started working ok. We used 2 external USB keyboards, so we ran both station on in every possible band combination to make sure RFI problems were not present.

Finally the station was ready to go.We ate our first bbq of the weekend by Friday's noon. Santi LU1FT joined us and at 2:30 PM, I took a nap to recover from the trip. When I woke up Fabi LU1AEE and Marco LU7ACW (Fabian´s 14 years old son) were at the station. Now going back to the contest. I started it on 20 which produced 230 Qs during the 1st hour. After 2 hours we switched to 40 and realized that we had a big SWR. Very fast Santi and Karl checked the feed line connector outside of the shack, in the meantime,I headed for 80 m and ran 22 Q´s at 02 UTC which is quiet a good number due to the bigEU-USA wall to wall qrm. When the 40 antenna (3 el) was working again we went to 40 m and made 140 and 170 Qs reively .That was our first night.The morning was slow. At 1PM UTC we started working station on 15. We continually checked 10 but the band was dead for most part of the contest. We ran a few stations on 10. During our lunch Juan Pablo LU4DX and Jorge LW4EU payed us a visit,that included our second bbq of the weekend. I want to congratulate Marco LU7ACW, who didn't operate but he was always checking bandconditions and put multipliers into the band map during the whole contest! He didan excellent job! Thank you Marco!!

During the first night we didn't notice any difference between our 2 El DeltaLoop and the beverage. Fabian, Marco and I checked the bev and fixed it, something wasn'tworking well. Now we are planning to put another one for the SSB one. Our 160 slooper played well, but I have to confess that we didn't pay muchattention to 160. Lucas just moved some stations from 80 to 160, I want to congratulate K1ZM andK3LR who were the strongest signals on Top Band!That was it. Another excellent contest from LT1F. We all want to thank Karl LU1FKR for his support and to all of you who contacted us. Hopefully we will beduring the SSB one M/S as well.

2007 CQ WW WPX SSB @ LT1F M/2

2007-03-31T15:35:00.000-03:00

We just had a great time during last WPX SSB contest. We were trying to put together a Multi Multi operation, but our friends from LP1H had decided to test LU5HM's station in the Multi Single class. Lucas also invited Roberto LU2FA, the owner of LR2F, but Roberto had also organised a Multi Single from LR2F, with LU6ETB, LW7DX, LU5FF and LU1FZR. Roberto is continually improving his station and has already achieved a great performance.The LT1F team for this contest included: Karl LU1FKR (the owner and driving power of LT1F), Lucas LU1FAM, Fabian LU1AEE,Juan Pablo LU4DX, Diego LU8ADX and myself. Everything was in place for the contest. LU1AEE and I tested the station during ARRL DX SSB, and there were no issues, except for the 20 M ant not rotating 360º. On Friday I woke up early around 4 AM, to go to LU8ADX's where we were to meet LU1AEE. From there were traveled to LT1F bycar, it is a 3 hour trip. When we arrived in LT1F, LU1FKR was there working as usual. We unpacked everything including LU8ADX's Ameritron AL 1200. Carlos prepared dinner for us. A great BBQ! We spent a long time talking about our hobby, future improvements to the antenna farm, etc. etc. Around 4 PM, LU4DX arrived in. Juan Pablo carried his IC 775 with Inrad roofing filters for the occasion. Carlos, started to hook up the coax stubs at the output of the Six Pack. Each stub is located at an electrical 1/4 of wave of the reject freq away from the amps.

I set up the network and N1MM was ready to go. We had positioned the two stations side by side so the ops could reach the antenna switches and rotor control boxes easily. Although the stations were very close spaced and sharing antennas through the Array Solution Six Pack, there were no inter- station interference at all. We even did not connect the RX bandpass filters, with only a couple of exceptions during the weekend, and not because there was QRM, but just in case. LU1FKR also set up an Icom IC 765 for spotting purposes, connected to a Log Periodic. Mainly to check for 10 m openings.We had no cluster this time, so the only way to know when 10 opened was to listen to the band. Around 6 pm, Lucas LU1FAM, arrived and the whole crew was there.Prior to the contest, we talked a little bit about propagation and decided that 15 and 20 would be good options to start the contest. Indeed it was the right choice as we ended the first hour with almost 400 Qs.

Then things started to slow down as we moved towards the low bands. 20 M remained open for quiet a long time. 40 mts was very tough this time. You know, March Equinox is not a good time for 40/80 mts from LU. May for example, is much better. So we spent most of the night on 20 and 40. 80 was very nosy, and with week signals, at least in the 2 el wire array. We decided to take that array down, cause we were never satisfied with its performance. The array was built in the previous years. It was a 2 el driven broadside array, supposed to have the radiation pattern favored to North, but well. During the previous days Karl and I decided to install a 2 el full size Delta Loop for 80 mts, what we did on Saturday. I designedthe antenna using MMana-GAL and Nec for MMana. The whole installation process took about 10 hours from 10 AM to 8 PM. We really learnt a lot doing this job. But most important that when it comes to antenna performance, there is no room for guessing at all. The antenna performed extremely well. We made 41 Qs mostly with USA stations. Everybody copied our Callsign at the first try and gave us very good signal reports, including a 10 Db over S9! As everybody was loud on the delta loop, there was no need to use the Beverage for RX. We tested the delta loop AM during Sunday.Going back to Saturday. When 15 opened everything seemed to be OK, although signals were very week, everybody was so excitedwith the contest, and LU1FKR and I building the Delta Loop, that we forgot to lunch!!!!!!!!!!!Ten meter opened quiet well, including a little but solid EU opening. The first day ended up with 3300 Qs in the log.So we thought that we could eventually achieve some 5500 by the end of the contest, but after 00 Z on Sunday, things startedto change. Rate went down and down during the night. We stayed on 20 and 40 most of the night with the exception of aboutan hour on 80 to test the new antenna. LU4DX and LU5DX on 20 and 40 respectively stayed up all night transmitting long endless CQs to catch a few takers. As I had not slept since 4 am on Friday, and having spent so much energy installing the Delta, Ireally felt tired. LU8ADX woke up at around 5 Am LU time and shifted positions with LU4DX, and later around 8 AM LU1AEEtook my place. I went to bed and requested LU1FKR to wake me up at noon to cook the GIANT PIZZA.

I woke up at 1215 LUT, and started the Pizza Ritual. Which ended at around 1530 LUT. Needless to say the operation stopfor a while so everybody could join the pizza party. LU1FKR achieved PIZZA MAN Honors this time! He was great in gettingthe fire ready to cook the pizza.About Sunday we can only say it was really slow!! 10 and 15 m never really opened. We hear several times LR2F running stationsat a good pace, but all the calling stations were dupes for us.The contest finished on 40/20 with a round of applause.
We all really want to thank everybody for the Qs. Congrats to the AN8A boys for a job well done. Also congrats to theOE4A boys for achieving such a great performance from their beautiful station. We really hope to work many of youduring WPX CW, this time a bigger delta loop and more Pizza!

2007 - ARRL DX SSB @ LT1F

2007-03-08T16:41:00.001-03:00

I actually never planned to enter this contest! But, as we all are getting ready for next WPX SSB, LU1AEE, LU1FKR and I decided that the ARRL test, would be a great opportunity to double check everything and leave things in place for WPX.So on Thursday before the contest, after a couple of quick calls we were ready for the contest.I really must thank Karl, LU1FKR for his never ending support and hospitality. He is of those persons that you can only meet through amateur radio!! He never refuses when there is a chance to enter a contest from LT1F, instead he feels really happywhen we visit the antenna farm.

LU1AEE and I departed at 18Z from LU1AEE's in Buenos Aires, three hours later we were arriving in LT1F antenna farm in Rosario.Ariel, a neighbor who lives close to the station, gave us the keys. A few minutes later, LU1FKR joined us. He carried the rigs IC 775DSP + IC765 and the Drake L4B.You know, the station was not used very much during last year. Lucas LU1FAM, entered a couple contests. But there was no big Multi Multi for CQ WW. Anyway, everything seemed to be in place. Karl, started to hook up everything. There was only one minor repair to be done in the control cable of the 40m antenna rotor. Ariel and I fixed the cable, and that was all.We pointed all the yagis to USA, and we were ready to start the contest. I wanted to record audio, so we hooked a splitter to the phone jack in the 775, and from there we run a cable to LU1FKR's notebook and used total recorder to do the job.I started the contest on 20, because 15 sounded really punk.

As I have no experience in SSB contests, I really felt very nervous during the first hour. Anyway 296 Qs were in the log, at 0100 we shifted positions with LU1AEE, cause I needed a rest after what for me was like a dream come trhough. I never thought that I was able to make more than 200 Qs/Hour on SSB!Anyway, now I believe that more than 360/400 Qs/Hour are possible on SSB, cause there were lots of CQs during the big run. So, maybe from the Caribbean, with a continuous pile up you can do that.Conditions were really bad, we just had a few hours over the 200 Qs mark. Ten meters never really opened on Saturday. We only managed to work 136 Qs and 17 states the first day, and with very weak signals and deep QSB. Lots of stateside stations that did not know what the contest was about, so had to explain them what it was. One funny thing happened to me on sunday afternoon on ten. I was running stations on 28430. I was there for about an hour then I started hearing two guys rag chewing on my freq. The pile up was consistent so I did not want to give up and QSY.After a while, one of them who said to be N0XK, started making funny jokes about contesting, I asked him to QSY, and he refused, cause he was talking to his neighbor. I told him that I had been using that freq for over an hour, which he did not believe, anyway he left after complaining a bit and calling me liar for a while. I believe he did not have a clue about solar cycle, propagation, QSB and all that stuff! 40 M played well the firs night. There was a big thunderstorm but the beverage was of great help. Same thing on 80. Anyway we are building a new antenna for that band.No 160, but I'm sure we will build some new antenna for top band. Lots of stations requested us to QSY to 1.8, I reallyapologize guys, we will solve the lack of a good 160 antenna soon.Second day, was much better on ten, we finally worked 699 stations on that band.

Wow! First plaque ever in CQ WW DX for LT1F!! It was really a very fun contest. We really had a blast. We operated with two stations, sharing antennas with a six pack switch. Stubs were located at the output of the switch. Rigs included an Icom IC 765 and a 775 DSP driving an L4 and a TL922.
