[amsat-bb] NO-84 mystery solved

I gently asked him if perhaps he was over-modulating his signal, among a
bunch of other friendly ham-related topics.


He answered the other topics but not the over-mod.  I shall listen on
another pass.


It is weird, Joe.  I remember doing ½ watt on PropNet PSK back 10 years ago.
How could he be hitting the bird if he’s using ½ watt?  Or even 5 watts?
Unless he has a long boom yagi, but I don’t think so.


And I still can’t get through the downlind!  28120 kHz, 1500 Hz audio, 50
watts out to an off-center-fed dipole at 64 feet.  I tried both with my Flex
5K and my TS480 on 28120.  I monitored the downlink with SDRPlay receiver so
I could see the entire passband.  Nuttin.

Did you tell him what was happening?
I honestly can hardly believe that he doesn't have something drastically
Because guys that run that beacon program rarely run more than 5 watts MAX.
most are like 500 milliwatts 1/2 a watt.
