Sometimes the offset in the transponder changes slightly. This is especially true with VO-52 and AO-7. On these sats, I use the RIT to touch up and make sure I can hear my self plainly at the beginning of a pass. This is a little easier than the offset feature in the software.
I hope that makes sense. 73, Drew KO4MA -----Original Message----- >From: Les Rayburn <l...@highnoonfilm.com> >Sent: Apr 23, 2013 3:40 PM >To: amsat-bb@amsat.org >Subject: [amsat-bb] SATPC32 and IC-910H > >I'm very new to satellite operation but have been having a blast for the >past couple of weeks.
