I am having trouble tracking the Doppler shift on VO-52 and wondering if I am tracking backwards on the Doppler as it seems the frequencies seem to diverge as I am operating. I am using the recent version of SatPC32 and this is my Doppler.sqf entry, is this what others are using? VO-52,145900.29, 435250.57,USB,LSB,REV,0,0 Michael K3MH
