another point to the DDE aspect:
just working on the DDE link between SATCONTROL and HDSDR. At the moment
HDSDR supports only Orbitron (Doppler tracking interval 1s), HRD and

If I change the application name of SATCONTROL to Orbitron, the link can be
established and it works. The

have some that may or may not qualify.

Mike,
First of all, thank you for the very great software :)
Just to clarify, in this case you will be tuning dopper at HDSDR
instead of FCD control level? Which if I get it right will result in
the I/Q of the pass being recorded without doppler control?
73, Sion, 9M2CQC
Quoting Mike
Sion,
exactly, the LO frequency of the FCD should be set to a fixed frequency,
e.g. the center frequency of the pass band.
You move the TUNE frequency with HDSDR through the spectrum according the
doppler correction.

Hi,
Can anyone on the list point me to source of high resolution images of
AO-40/P3E.
Need it for a magazine article. The images found via google are all low res.
Tried Peter DB2OS at amsat-dl but no reply as yet, and my deadline is two days
away.
Thanks

Yes Phil, you are correct. Communications and earth observation in orbit are
great examples of space applications that have succeeded. But, they are also
things that we've already done. I admit that there is probably more to explore
and learn here, near to us, but I was really thinking about

The ARISSat web site shows how to get a Reception Certificate for Voice ID,
Voice Telemetry, and SSTV.
I have screen shots of the BPSK-1000 reception and CW.
How does one claim a certificate for BPSK-1000 reception?

Ron,
All telemetry *Reception Certificate* requests, either voice or BPSK, should be

Appeared to be in Lo Pwr mode, No BPSK telemetry or FM heard.

Low power mode, I think. 2 minutes off after the telemetry, then voices and an
