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...
