With SatPC32, you won't need to set memories on the rig... in the Doppler.sqf file, you need to have an entry for VO-52 that looks like this:

VO-52,145900,435250.3,USB,LSB,REV,0,0

This tells your radio the relationship between the uplink and downlink frequencies, what modes to use, etc., for that particular satellite. You can either open Doppler.sqf in Notepad (it's in the folder where you installed SatPC32, usually C:/Program Files/SatPC32), or from the Auxiliary Files section under the "?" option on the menu bar. Make sure that you not only have matched the addresses for your radio in the Setup menu, but the baudrate aand COM port as well, and put in a CAT delay value of around 60 or so. Then when you select VO-52 as the active satellite and press the "C" button in the upper left of the display, the program should automatically switch the radio to Satellite mode, LSB on the uplink, USB on the downlink, and set the frequencies to the values in the Doppler.sqf file. (Don't forget to turn the squelch knob, which is the RF Gain control in SSB mode, UP) You can then tune up or down from there manually, and the uplink VFO will track your changes to the downlink.

Once you can hear yourself on the downlink, follow the instructions in the file FAQ.htm, in the section titled "AO-40 Operation," to fine-tune your uplink to match your downlink (every radio is slightly different).

You should then be good to go!

Bruce:

Think I found part of the problem. I glossed over the CIV addressing. I am used to applications that "know" the default CIV addressing, so I hadnt looked at it. Although I hadnt changed mine, I looked at the settings in my 910H and changed the settings in SatPC32. I can now see there some indication of RIG control. Have to figure out now how to get things to work.

I dont use the satellite function in the radio, I put the vhf frequency in one memory and uhf in the other. I shift the receive channel into the slave part of the radio (lower display) and put the transmit in the higher display.

I will continue to look at the docs for SatPC but would appreciate any pointers you can give on how you use SatPC32 with the SSB birds (i.e. setting up the radio, etc).

Thanks, Ron
