Im getting back in to satellite after about 6 years being off.  My ts-2000
used to work great but when i have tried it this time, every satellite is
very weak and almost cants hear anything.   To troubleshoot if it was my
antenna system, i placed a new FT-991A on the antennas.  I hear the
satellites pretty well.   im using satpc32.  but the ft991a is a halfduplex
radio and i can not hear my own signal.  This means i cant calibrate it to
the correct frequencies.   I know people are using the ft991a.   Does
anyone have a way to calibrate the uplink or downlink using the satpc32?

antennas are 14 element 2 meter and a 11 element 70 cm antenna on az/el
rotor and about 100 ft of the new messi low loss superflex cable.

Thanks, Tom Medlin W5KUB
