[amsat-bb] Oribitron WispDDE problem

[David Quick]

I have Orbitron and WispDDE 3.4.7 installed on my 32 bit Windows 7 PC and
I’m trying to use them to control my Yaesu FT-847 for Doppler shift
compensation. WispDDE CAT control of the FT-847 works but after just a few
minutes of operation I notice a large discrepancy between the uplink and
downlink frequencies displayed in Orbitron VS the uplink and downlink
frequencies displayed in WispDDE and on the 847. The longer the software is
running the larger the discrepancy and after 15 minutes the two are off my
over 1 MHz.

 

The other problem I’m seeing is that each time Orbitron and WispDDE send a
command to the 847 it interrupts PTT and stops my transmitting.

 

Can anyone offer any advice or a solution to the above?

 

I also have an unregistered copy of SatPC 32 installed and while it controls
the 847 perfectly I prefer the look and feel of Orbitron.

 

Thanks
