Right now, the radio is off to support the docking operations for the
Progress. When it is on, the radio basically supports only one operation at a
time. If Crossband is active, packet is not. If packet is active, SSTV is not.
If the crew is talking, consider yourself fortunate.

hi Frank
thanks for The information
how about APRS DIGI in 145.825 Mhz also open ?

Hello The Net:
SINAD is nice because the complete path from RF thru IF thru audio
demodulation can be tested.
Also a cost effective approach, Last SINAD meter I got was about 100$.
It is a HELPER Instruments,Inc. model SINADDER LINEAR 5
SINAD measurements require an external signal generator, and variable
attenuator.
A noise figure meter can usually test the RF path or the RF thru IF
path, but NOT to audio.
For my HP-8970B, the IF would have to be more than 10 MHz, the low freq
end of the machine.
NF meters are about 10-20X $$$ the SINAD meter purchase.
I use my NF meter in a Y factor mode, which is essentially a signal to
noise ratio.
SINAD is also a Signal to Noise ratio, with Distortion taken into
consideration.
(S+N+D)/(N+D). When noise is very low, and distortion is also low, thus
a S/N.
SINAD was used by Motorola and FM radio testing with a 1000Hz test
modulation.
Testing can also be used for testing SSB receivers, using a clean
carrier with no modulation
and tuning the RX for max signal, max S/N, max SINAD reading.
Both instruments have their utility.
