Hi Bob,

Two different radios are used on the ISS. The SSTV pictures on 145.800 were
sent using the Kenwood rig in the Russian segment. The packet digipeater on
145.825 is an Ericcson HT at lower power and different antenna than the
Kenwood rig.

On Saturday when the SSTV signal was still just an unmodulated carrier on
145.800 I was able to digi on 145.825 up/down.
