When aiming at the APRS satellites (ISS, AISat, any others?) should I use Wide or Narrow FM? I vaguely recall reading that narrow is good, but I can't find the reference. Your assistance is appreciated! Steve AI9IN
Hey Steve!
I've found that AISAT-1 works better with FM-Narrow. It's my understanding that the other APRS sats have always worked fine with regular FM... that's what I use for all but AISAT-1.
Unfortunately, for quite a while now the only active 2m APRS satellite has been AISAT-1. However, it has not been heard since 3-Mar. Certainly hope that's temporary!
Of course we all look forward to the day that the ISS digipeater is back online, too.

Of course I spoke too soon - thankfully AISAT-1 was working great on the 1600utc pass today (05-Mar) and saw packets from AI9IN-7, too!

Hi Scott,
Quick question... AISAT-1 is which catalog number? I recall some discussion a while back, and I've got #44104 configured in Gpredict. But I also see AISAT (40054), AISSAT 1 (36797), AISSAT 2 (40075), and a few others with similar names.
Which is AISAT-1 (one "S", with the dash)?
Thanks,
Greg KO6TH

Yes, I show that as 44104.
Keep in mind that it's attached to a platform with several other objects, so depending on your TLE source, it might show up as "PSLV R/B" or something similar.
