When AO85 is selected the ic 910 does not select fm. I have also noted that AO 85 seams to be off frequency from 145980/435180 and when I changeĀ SAT 32 pulls it back to what it wants.How should I correct this. Should I change the Doppler sqf to some other frequency? Jim KI6WJ
Jim,
The frequencies have been determined to be somewhat lower than the prelaunch estimates, due to the higher than expected satellite temperatures. I use this:
AO-85,145979.0,435172.0,FM,FM,NOR,0,0,RPTR
145,979.0 MHz is about right most of the time, but in periods of continuous illumination, it can get down to 145,977.5 MHz. Just let the 910 AFC do its thing.
Presumable the uplink also shifts, but the satellite receiver AFC should help with that.
73s,
