Re: Problems with the Kenwood TS-2000 for satellite work



 Cris you should of asked here first. You would of got a heads up on the 
problems with the TS-2000. You might also want to look into TRX-Manager to 
control both radios. I think it can properly control your two rigs for sat 
use.
  I recently purchased a TS-2000 myself, but not for sat use. The Kenwood's 
are the best transceivers to control remotely over the internet. I travel 
alot for work and can  now (with real antennas!) work HF, sats, and my local 
home repeaters from anywhere in the world, from my hotel room. This saves me 
the hassle of trying to transport a radio, power supply and antenna's 
through the airport. It's a shame Kenwood doesn't fix the 2000's sat use 
problems, as it is hands down, the best on HF, multi band/multi mode 
transceiver out there.  When I'm home it makes  a great backup HF rig.
