[amsat-bb] Falconsat-3 upload problem

Hello Hans, I have not been working FS-3 recently, since the IC-9700 will
not do 9600 packet [iCom, please fix!!] :(    So I cannot comment on recent
uploads.  However, to add to Bob's thoughts--are you running full duplex?
It's critical.  Also, is your transmit signal desensitizing your receive
signal?   That is important, too.

In the next week or so I will change radios at my station so I can again
use FS-3.   I'll be better able to share current experiences with you.

73,

Mark N8MH
