What happened today:


Left: This is a wide angle view into the CN8WW truck. The truck has an inside space of 12,50m x 2,50m. This is split up in two "rooms": A smaller one, which you can identify from outside as the "upper" end, which is right above the axis of the truck engine. It's a nice "shack" and houses the 10m operating position. This is a peek inside. Left and right are some wardrobes and - very important - the refridgerator! Right: This is the larger room, which houses the 15m and 20m operating positions. The picture is taken during setup time, so it doesn't look too neat and many things are still missing. Final setup may be seen in pictures of Nov. 25/26...


Left: In the left picture you can see the Bandpass Filter for 10m. Every band has its own set of filters (three), which is very important to enable a Multi-TX environment. If we did not have such filters, an efficient M/M operation would be impossible. The picture shows the final filter with 7/8" Hardline on one end (running to the antennas) and RG213 on the other end. We decided that "N" connectors is the standard to choose, since they are real 50 Ohm connectors, and not only shielded banana plugs like PL/UHF connectors [dunno who ever named them "UHF"... Must have been in the very beginnings of Amateur Radio...]. We choose 7/8" Hardline for the long runs to have lower losses - on receiving and on transmitting. Alone this cable gives us 2dB more on 10 meters than last year - in both ways... Right: The other picture is a sunset picture showing the South America Beverage on the hill. The Atlantic Ocean is behind... We hope for MANY DX stations calling in on the low bands 40, 80, and 160m. We have constructed a special Beverage Box, which enables us to simultanously use the Beverages on all three lowbands. And the improvement to last year's setup is: since we have two radios and two OPs on all three bands, now BOTH of them can listen on DIFFERENT Beverages - independently from each other. More info on our receiving strategy can be found here on a later day (probably Nov. 23)...


A similar principle is also used on the highbands 10m, 15m, and 20m. These bands have a dedicated monoband vertical - only for listening purposes on the second radio. Being able to listen to the same pileup with two radios and different antennas enables the two operators per band to pull out MORE complete callsigns from the pileup in the same time slot. The two stations can be worked in a row without having to ask in between. This is speeding up the pileup efficiently, but the danger is that it can also be mistaken by the "audience" that we take breakers... This is not the case, so please don't panic... Shown here is the third Yagi for 20m, an old but still reliable Hygain 204BA on a 16m crank-up tower, plus the 20m vertical. In the other picture you can see the feed point. The verticals were made by Stanko, S50S, who is selling this good stuff - and also more and bigger Yagi antennas...

Thanks for working CN8WW again this year in CQ Worldwide DX Contest:
