[amsat-bb] Uplink frequency of FM satellites

[Erich Eichmann]

Ron,
if you use SatPC32 you can use the "Upl. Calibr." controls in menu CAT 
to correct the uplink frequency in steps of 10, 100 and 1000 Hz (while 
you are transmitting) to check which uplink works best. The controls are 
disabled with FM-Sats by default. To enable them also for FM sats click 
the "V" control to "V+".

73s, Erich, DK1TB
