Hi everyone,
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 need one that I would not have to tinker with by hand; I want to use the radio (and the AO-51 pacsat) as the primary means to communicate with an ocean-deployed robot. 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"?

Oh boy, and here I just bought a used dual band mobile on the cheap (no transmit) to take care of the birdy problem.
Do you have any idea why the birdy would show up on a different radio? Could it be a matter of a lack of shielding? It just doesn't make any sense to me why a different rig would get that interference on receive, and even when using a different antenna.
Others have suggested using a preamp on 440, and turning off the 2000's internal preamp and lowering the rf gain, therefore using the preamp to get rid of most of the birdy.
But I guess I'll find out for sure when my other rig gets here.

I own a TS-2000. The birdie problem on SO-50 and AO-27 is quite
real,
and there is no fix I know of. I find that the birdie is so bad that even if I use a different receiver on UHF, I pick up the birdie on
it
as well! So it is a worse radio regarding satellite work than the
ICOM
if you care to work these birds. However, if you consider the fact that a fine HF radio is thrown in at no extra cost, that there is continuously adjustable filtering also at no cost, you might prefer that trade-off. I'm reasonably pleased with mine.
However, if money were no issue, I would get the ICOM for satellite work and a different HF radio with even better characteristics.
