Not everyone runs QRO so sometimes you might have to turn up that audio gain a little.

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?
