[amsat-bb] Using PSTRotator Tracking S/W with iCOM IC-910H

[Dave Hallidy]

All-

I've been working to get my radio working correctly with the PSTRotator
AZ/EL control software.  The software tracks the satellites beautifully, but
the Doppler tracking seems messed up (which is likely an operator problem on
my part), so I need some help if anyone else is using this combination.

 

Here's my problem: When I follow the instructions given in the manual, I can
get the software to track the Doppler, but the tracking can't seem to be
tweaked to get the downlink in exactly the right place- it's always about a
kHz or so high.  Of course, if the station I'm working is on my downlink
frequency, I have to adjust my RX to get the proper audio frequency.  Then
the tracking takes over and my TX frequency jumps to again offset the
downlink (it's tweaking the uplink, because the station I'm trying to work
is still in the right place).  What am I doing wrong?

 

Has anyone here ever seen this issue and gotten this to work properly?

 

Thanks in advance for any help- I really want this working before Field Day!
