... You use a program called InstantTUNE together with InstantTRACK which allows automated doppler tuning using mic pushbutton rigs. Instantune only allows tuning EITHER the uplink or the downlink so if you want to be FULLY automated, you'll need a pair of old 386 IBM's (or equivalent) and a pair of monitorsd from the nearest computer company/school skip.
Everything else I can think of is home brewed and is to be found on the OBSERVATIONS page mentioned earlier.
Hi John and AMSAT Friends,
I am thrilled to hear you are using InstantTune for doppler control it is still my favorite program :) However,...
I would just like to point out that InstantTune + InstantTrack provides full Doppler tuning for BOTH the up and down links even with mic-button radios. Just connect radio 1 to parallel port 1 and radio 2 to parallel port 2.
I apologize if the manual is confusing on this point What it is supposed to say is that it will only tune one link PER RADIO for mic-button radios but it can actually tune up to 3 separate mic-button radios simultaneously (1 up and 2 down. Will anyone ever bring back mode K/T?)
I have personally used an FT-290 (with mic-button tuning) along with a 432 to 28 MHz converter into an HF rig to make tons of satellite contacts on the old FO-12 and FO-20 birds.
So, to be clear, you do not need more than 1 PC, and it can even be a really old 20MHz '386, for full doppler tuning, you just need 2 parallel ports to interface to the 2 mic-button radios.
If anyone needs help getting this working, please email me.
