Hi Bob,
Thanks for the info. I actually own a Kenwood TH-D7. Is that what you're referring to? I was under the impression that the TNC on the TH-D7 is permanently crippled and I couldn't use it to effectively communicate in both directions to a pacsat.

Is there a radio that is small and lightweight that I could interface to a computer easily to receive and transmit packets to AO-51? I want to use the radio (and the AO-51 pacsat) as the primary means to communicate with an ocean-deployed robot.
Use any of the APRS radios (D7, D70, D710). They all have 9600 baud TNC's built in... Operate in UI digipeat mode assuming your command/telemetry is sparse and infrequent and not high volume..

Obviously my hand would not
be there to correct for doppler, etc.

Hi All,
My Kenwood TS-790E has absolutely no "birdies" in 2 m ,70
cm and 23 cm
and this is why I like it very much.
Tanks very much the OM that sold it to me as used to buy a
new TS-2000X
and his "birdies" !

My 847 has a number of birdies in the satellite band. I use
a magic
notch to silence them. It is not the perfect solution but it works.

The TS2000 generates an internal signal (a "birdie") on
the downlink of
SO-50 and AO-27. This signal overwhelms the satellite
signal in most
cases,
making it difficult if no impossible to use on those two
very popular
satellites.

Pardon my ignorance, but what the heck is a "birdy
problem"?
