[amsat-bb] Modulation levels on AO-85

[jerry.tuyls at telenet.be]

Spending some time here by telling several times on AO-85 passes about bad modulation to the same stations, but they DON'T listen.

Just ignoring them, because i cannot understand them on my TS-790/FT-847.No narrow FM and no PL tone. Never got a problem.

And please...why do some stations upload logs with DWNlink freq on sat qso's instead of the UPlink freq?
Always having some rejected qsl's because qso's don't match due to wrong band. I log with VQlog, uplink and dwnlink freq etc, so i think the TX-freq is most important for logging sat'qso's and not the RX-freq?

Like Jerry said, its more an issue with mic gain or poor mic technique than anything else.

>>> I’ve noticed lately that many stations on AO-85 have barely audible modulation. Yet other stations have clear audio with good quieting. 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?
