[amsat-bb] Old FT-847 and doppler control

[Bill (W1PA)]

I have one of the older FT-847's that does not have 
bidirectional CAT.

My understanding is that I can still use a PC to 
control/adjust doppler,
but that I must tune the radio from the software only. Is 
that correct?

If so, what software would you suggest, Linux-preferred? I 
don't need any other control
other than doppler correction on a linear bird pass. Does 
gpredict do this?
