I'm very pleased to say that the issue of my TS-790 going to Auto LSB during Doppler updates from SatPC32 has been solved. Vince KB7ADL suggested a reset of the radio (hold A=B & turn radio on), which I did this evening and the problem disappeared. Now mode is kept as put from either SatPC32 or front panel with Auto off, and mode is automatically switched as designed with Auto mode select on. Thank you very much, Vince KB7ADL, and thank you very much Erich DK1TB.

Thanks, Robin Midgett K4IDC

I'd like to know if anyone on the list has a successful configuration for

SatPC32 & the Kenwood TS-790. The issue I'm seeing is that whenever the 2m band is used at or above 145.800, the radio automatically sets itself to Auto LSB, regardless of whether or not it was in Auto mode selection to start with. I'm aware that Auto mode selection is a built-in operating convenience, but it's not convenient if the radio or the software changes that mode setting. If I try to use a 2m frequency on FM at or above 145.800, the rig goes to Auto LSB. After it does this, I can manually set it back to FM or USB or LSB without the Auto feature, but upon the next Doppler update from SatPC32 it goes back to Auto LSB....every single time. I've tried varying the CAT delay in SatPC32; no help.

I've been in contact with Erich and he's been very patient and helpful, but

the issue remains. Erich said there's no command from SatPC32 to enable the Auto mode select, and I believe him. That fact is supported by the external control manual which lists all the available commands for the rig under computer control...Auto mode selection isn't listed in the commands.

...

Anyone?

Thanks, Robin Midgett K4IDC

Hi Robin,

I use Satpc32 to control my TS-790, I've never had this issue. you might Check the command line in doppler.sqf to be sure Satpc32 isn't commanding the rig to LSB. I've had my TS-790 since the mid 1990's. One other thing you might try. The the control logic in the rig might be messed up. Do a cold reset, or a full reset. Let us know what you find.
