Hi all, In an attempt to dabble my toes in the linear transponder pool, I asked a FT847 owner friend to bring his rig over to try and understand the mechanics of making it all work with the computer interfaced. Got SatPC32 to communicate at 9600, 8, none, 1, none, with the radio and the radio responded to changes I made on the program like using keystrokes to modify the frequency of uplink or downlink. Problem is that although the program was tracking Doppler correctly, the radio was not tracking at all. With the multiple lines of possibilities on the Doppler.sqf file as is the case for AO-51, I can go to the CAT dialog and change the mode frequencies just fine, the radio goes to the new frequencies and even reflects the current state of the Doppler shifted frequencies but from there, no Doppler corrections occur.
Now I remember reading the "Manual" that "CAT Delay" for the FT897 needed to be set to 20. Cat Delay is in the "Radio Setup" dialog is defaulted to 70. I realize this now after the fact with radio not in my presence. Is this the reason that the above mentioned problem could be occurring? I hope to make another go at this in a few weekends in the hope of getting ready for Field Day. Thanks for the help of the list.
