RE: RE: Doppler correction for ISS on FT-847



No problems there, Joel.

And thanks to Don for documenting his findings.

Ok, you're right.  I didn't test it that far.  The radio will not transmit
when both VFO's are on the same band.  Sorry for the confusion.

Does the 847 transmit when both sides are on 2M in SAT mode?  

I have tried doing what you mentioned, however transmission is not allowed
when both the TX and RX are of the same band in SAT mode.  All I get is an
"Error" message.

Maybe I have left out something here?

I have followed this thread with only minimal interest, but I finally tried
this with SatPC32.  In SatPC32, my '847 tunes for doppler with the ISS.  I'm
watching it change freqs now...  It's in SAT mode and both sides are on 2m.
Both sides are changing freqs..  Call me crazy, but it *appears* that
SatPC32 has solved this issue.

All,

I also made a stab at this problem with my W6IHG Radio Tuner. I tried
messing with the repeater offset and split etc to no avail. So I also gave
up.
