Hi Erich,

Thanks for the great upgrade. I see you incorporated the CW-N mode and the display of the DOPPLER.sqf line in the CAT menu I suggested :)

You are correct, one of the issues with fast changes in Doppler on a CW-N signal is that it jumps in pitch a lot. I enabled the x5 and x10 mode and I can see SatPC32 is now polling the IC-910 much quicker (the SUB light on the LCD flashes an instruction is sent to the rig via C-IV). But what I cant figure out is that even if I set the CW/SSB interval to 10Hz, the rig only changes every 100Hz. When I make small changes to the VFO by rocking the dial back and forth on the rig the full update to the goes back to the frequency display in SatPC32 right down to the last Hertz but as soon as I let go of the VFO knob the IC-910 jumps to the nearest 100 Hz increment up or down when the next C-IV instruction is received from SatPC32. So it seems the full frequency command is going from the IC-910 to SatPC32 but its not accepting it from SatPC32 ? Or am I missing something ? Maybe someone else can test and confirm this.
