Tim, I have an FT817 as well and have had the same problem as described. I hope others can offer suggestions as I had the same experience in searching the online suggestions and none had it working properly. There were only a few settings to try to change and none were a solution for me. The difference here is that is an extra rig for me and not the one I usually use for satellites.

Hi all,

I just finally upgraded to general over the weekend, so I went out and got a

Yeasu 817. However, I'm having problems with using it for Doppler tracking

in SatPC32. Here's what it's doing.

When I turn the control on, the radio will track the frequencies that are

showing in SatPC32 for both the uplink and the downlink. It switches between

the uplink and downlink frequencies quite often- about once per second. The

radio will also switch to the correct mode (FM, etc). However, when I hit

PTT, it transmits on the previously stored VFOb frequency.

So, for example....

1) I tune vfoa to 50.1Mhz, AM and vfob to 50.5Mhz, AM

2) I turn CAT control on from SatPC32

3) The radio starts switching between the vhf downlink frequency in USB and

the uhf uplink frequency in USB about once per second to correct for Doppler

4) When I press transmit, it transmits at 50.1Mhz, but in LSB

Obviously, it should be flipping between the VFOs (instead of 2 freq's in

one VFO).

So it seems like its flipping frequencies in one VFO and then trying to

transmit in another VFO, where it changes the mode for transmit, but not the

frequency that was originally stored.

Any help please?
