Re: Freq Chart for AO-40??



Doppler isn't being considered at all, Gunther...this is a "get in the
ballpark" frequency chart that is quick and dirty...more a "where should I
start looking" kind of thing than anything as refined as doppler. I can
approximate the doppler from looking at IT as I use the bird...I just wanted
to know where to start looking in the first place <grin>.

Actually, I'm looking for an AO-40 entry for the configuration file
itune.cfg, which drives the program

ITUNE.exe....this will automatically control doppler for the FT-847 via it's
serial port and works with the tracking program InstaTrak from AMSAT. Once I
know the particulars of the AO-40 section of that config file, I'll let it
do all my doppler correction for me. In the mean time....

tnx, 73
