SatPC32, AO-85, Icom IC-9100
This post is specific to Icom IC-9100 users.
There have been some ongoing discussions about whether or not to use Narrow FM for uplink or downlink on AO-85. My observation is that Narrow FM (Filter 2) for the downlink works best. For the uplink, I leave Filter 1 enabled.
This is easy to do in your DOPPLER.SQF: AO-85,145980,435175,FMN,FM,NOR,0,0,Transponder
The first FMN will set Filter 2 for your downlink The second FM will set Filter 1 for your uplink.
I've also noticed Filter 3 makes LilacSat-2 sound best but I am unaware of a command via SatPC32 to select that filter automatically.

Great tip Clayton!
Works well as you described. Maybe send an email to Erich DK1TB and see if there is a Cat command for that, maybe he can even enable it in the main window as an additional feature.
