Hi Rolf, NR0T
The KLM has the model 435-40CX crossed yagi i.e. a 20+20
crossed elements complete with a on board switching relay
and phasing harness to get RHCP or LHCP from the shack
Since the above model is relatively old I don't know if you can
get one of it actually in USA but the KLM now M2

Hi Dan,
we have tested two alternatives: one is a decoder on a PC Card and the
other one is a commercial set top box.
The PC Card that we tested is Technotrend S2-3200 (around €60,00) and
you can also use a very powerful software TUTIONNE (free) developed by
Jean Pierre F6DZP. There is also a

Hi all
There is a DATV forum on the BATC website and there is also a DATV forum on
yahoo groups.
There is already plenty of DVB-S ATV activity in Europe, the US and
Australia. The low symbol rate planned for the ISS activities cuts down the
choice for available decoders but known to work
Did you look at the antenna plot on that web page?:
http://aprs.org/rotator1.html
At the proper 15 degree tilt of a fixed beam, the gain is down only 1 dB
at the horizon. At your proposed 35 degree tilt, the gain is down 4 dB on
the horizon where you need it most (70% of all pass times are below
This looks very interesting, wondering if it would be possible to tweak the
tuners in DVB-S reveivers so no conversion would be needed?
From http://amsat-uk.org/ :-
It is planned to transmit DVB-S signals on 2.4GHz at either 1.3Msps or 2.3Msps
with 10 watts of RF from the ISS Columbus module.

I am sure this has been hashed over in the past but as a novice to the
birds I am not sure how to proceed when operating one of the linear
transpondesr.
I looked at the latest editions of two ARRL publications:

I am so confused. Is anyone going to make up a paper, ISS HamTV for
