I have a north-south switchable 21m high phased pair for 80m with 1/8 lambda
spacing. It is optimised for 3520 kHz, the feed -Christman-system was made
according to ON4UNs book and software. Measurements were made with a General
radio bridge 1606B, oscillator and receiver. The system has a
Hi Ray
I would say TX3A did balanced 160m activity and proved that it is possible
to achieve using dedicated RX antenna for the location of the DX expedition,
most DX expeditions does not pay attention or do not get well prepared for
RX on low bands. It does not mean dedication bit the results
Kees,
What else is around your verticals? Just the fact something is not resonant
does not mean it isn't a problem.
To my ashtonishment, vertical 1: 28-j328 Ohm and vertical 2: 12-j320 Ohm
both on 1825 kHz.
The vertical with the smallest radial system has the lowest earth
resistance (around
Felipe, tks nice story. Only got you on 80...
Hope better luck next time!

Milt,
In this aspect all DXpeditions are equal.
Just one comment: Having a large person expedition can yield large
differences in 160m Q's compared to a two person expedition. On a two man
operation, the ops must decide what band to operate at night, 30, 40, 80 or
160m. They may want to make Q's

Tom,
Thanks for your reaction.
At 50m distance of both verticals I have a 16m high tower with a 3 el
Steppir. This tower has a radial system and is shunt-fed tuned for 80m.
There is some interaction with the 2 element system on 80m. 400 Watt in this
system generates less than 1 Watt in the
HC1PF was literally 5NN around 10 min before my local SR this morning. Most of
the time he is 559 to 579. Seems there is many EU stations on but many suffer
the same as me :-) still not in log. I guess he has an RX issue noisy band none
RX antenna etc. However we cant complain about his effort.
Hi Felipe,
Nice story!
I was one of the lucky ones (with PA3FQA) and I even worked you twice, due
to the up1, up2 etc confusion.
tnx,
Kees, PE5T

Tom, Thanks for the details on the Z for TB. On a related matter I

Hi Rune,
Yes, we are copying Luis in the US rather well. He has the usual RX
problems of listening to the US stations in their winter while he has
summer and the local QRN. He also has nearby BC stations in the high
end of the band. Tonight he had a US pileup on him. It was a very
quiet evening
Rick, I think it had more to do with getting something out of the shack
window with the tuner inside. I also think it had more to getting the
current maximum at the top of the pole. The OT's used to tell me they
just taped a #47 bulb and a small loop of wire at the top and fed some
power 20
Hello folks,
I was part of the ZY0T team on 2009.
I bring a half wafe 160m dipole with commercial made ladder line with me. I
was not sure of what kind of supports where available.
We had two stations running simultaneously, some hundreds of meters apart.
One site was PY1ZV and PY1NB and on the
