Traditionally, a simplex channel is one that can ONLY receive or transmit but
not both, as in a telemetry beacon or a

I'm still learning about SATs but I just was curious if my experience was
typical regarding CW activity.
On most passes, I am lucky to hear a single CW station on FO29 or other linear
transponder birds.
I monitor during the week from my desk when MacDoppler tells me a pass is
coming up.

The AMSAT.ORG computer has been upgraded and moved to a new location (still on
the UCSD campus). The new location required that a new IP address be assigned.
The transition should theoretically be seamless, but some users may have
trouble until their network's DNS servers take notice of the upda

Hi Tom, NY4I
There is more CW activity on VO-52 here over Europe, 3 or 4 stations on a
single pass.
Try over USA

The server was moved to a new location, and the IP address changed. You
might have better luck by flushing your DNS (`ipconfig -flushdns` I
believe), or by going straight to the IP (

If you can, call CQ. That's how I got the 1 CW QSO I've ever gotten on the
sats. I would have had 2 if I hadn't messed up the VFO.
I've really got to get my sat station set up again so I can try again... I love
the somewhat warbley sound of CW on AO-7. :)

That warbley or fm'ing sound is if we run too much power or there are several
people on at the same time. Those poor 36 (I think) year old solar cells are
working really hard. Try to keep the power to a minimum to maintain
communications.

I have been calling CQ. From the reports I am getting, I am not hearing the

higher than 15 degrees. My question is about handling the doppler shift.
If you do not have a sat program automatically correcting you rig frequency,
what is the most common or preffered technique? 1 - Hold the TX

Hi Doug, KA9DLP
Hold the RX steady and adjust the TX for doppler.This is what I did
manually from OSCAR-6 and I do actually on VO-52, FO-29 and
OSCAR-7
