Look in the DOPPLER.SQF file where you specify frequencies, modes, etc.  You have the option of FM, or
FMN for FM-Narrow.  I used a Yaesu which also has a FMN mode, and it worked fine.  You can select it
for uplink, downlink or both.  There are detailed notes at the bottom of the file on the options.  I
would suggest changing only the downlink.

Subject: [amsat-bb] Another SATPC32 Question-Icom 910H-FM Narrow Mode

Thanks to all who answered my newbie question involving how to change 
the transmitted PL tone for SO-50. I got several great responses, 
including at least one person who sent me their edited file for my use. 
The amateur spirit is alive, well, and living on the birds!

I've got a similar question regarding SATPC32 and SO-50. I've noticed 
that FM-narrow mode on the Icom IC-910H seems to deliver better 
reception of the satellite, and I'd like to change the settings in 
SATPC32 so that is automatically places the radio in FM-Narrow mode. Can 
someone guide me through how to make this change?

Also, I notice that polarity seems to be a larger issue on this bird 
than on the linear SSB/CW birds. My antennas are fixed in the attic in 
elevation, and can only be rotated in azimuth. I also opted to slightly 
offset the 432 antennas from vertical polarization to more of an 
"in-between", which seemed to reduce local noise and be a good 
compromise setting for shifting antenna polarization on the satellite. 
Anything else I can be besides adding AZ/EL to help reception of SO-50?
