[amsat-bb] Modulation levels on AO-85

[Frank Westphal]

I use LOGIC 9 and it uploads the downlink frequency.  I enter both 
uplink and downlink frequencies into the logging program LOCIC 9.  I 
receive lots of matches and that seems to be the accepted convention.  I 
know ARRL suggests uploading the uplink frequency in their 
documentation.  LOGIC 9 does not follow that recommendation and from my 
experience most other sat operators are not either.

YMMV

I have heard the some manufacturers of hand-held and mobile rigs are setting their maximum deviation to 5 kHz or even less. I have noticed the same effect on local repeaters. Has anyone done any tests of the deviation required for reasonable quieting on AO-85? Or are more stations using lower power than in the past?
