Terrible Repeater QRM on AO-92 at 15:40z
Hi Roy What happens when the world ends? You and I and just about everyone is not able to control the future. If we all thought about 'what if' we wouldn't have gotten out of the stone age and the Wright Brothers wouldn't have flown. All we can do is deal with the present and the facts we have at hand. I look at it this way. If all the idiots want to jam the crap out of the FM birds, so be it. That means they are leaving the linear birds alone. Mike va3mw
Mike, perhaps my use of the term "QRM" is incorrect, or perhaps you didn't listen to the recording?
This is not one or more "a-hole" operators intentionally trying to interfere with satellite operators. This is the output of a New England (we think, based on operator accents and 1 area callsigns) repeater that is either on the AO-92 uplink, or has a very strong harmonic accomplishing the same thing. From what I've read, the AMSAT team is working with at least one repeater on a solution, and they have continued to ask for recordings.
And again, I stress that somebody putting a repeater output in the same uplink frequency band as any of the linears will cause the EXACT same problem, if not even worse. So we should either nip this in the bud, or face giving up the satellite sub-bands entirely.
As far as your "what if" comment, people like the Wright Brothers DID, in fact, think "what if". In less than a week we will have the first purpose designed commercial space flight service....

If interference is on the Satellite Passband should immediately cease as per IARU Bandplans.
