Re: [amsat-bb] Terrible Repeater QRM on AO-92 at 15:40z
Yes, terrible QRM during this pass. Have recording as well but no call signs from repeater chatter. Cal / N3CAL

So... not to sound like I don't care, I really do.
But, there isn't anything you can do about it unless you capture the person with video with the mic in their hand.
Here in Toronto, several of us have spent thousands of hours chasing people. We even have video of a guy in his living room doing it. I had Industry Canada and the RCMP (since it was a Federal Offense) on the street with us. They agreed, he was breaking the law. To which they both said, so what. I have other more important cases and this is just a hobby. If you catch in interfering with health or safety, call us back.
And, with that. FM, DSTAR and DMR are about dead in Southern Ontario. And, there are a lot of hams here. The population is about 11 million.
The best solution. Give up on FM and move to a Linear bird. Invest in it and you'll love the difference. For myself and my friends, FM, DSTAR and DMR are dead. I do HF and weak signal SSB, CW, etc. Way more satisfying than the CB crap we are hearing now.
Ok, off soapbox. Flame retardant suit is on.

Mike, First.... With the WX now being FB, I'm making some sketchy plans to get out of home confinement and do some roving. But, with all the craziness on the FM birds I keep hearing about, I will probably plan most of my activity on the Linears. It would really tick me off to spend the time and money to activate some juicy Grid on FM only to be QRM'd into a waste of effort. Second... Sorry to hear about the radio problems in your area. It must be awfully frustrating for the Hams that spent the time and effort to put capabilities on the air and be unable to use them properly. I'm the License Trustee of three Repeaters for our Club. If I was to ever hear any of them being used improperly, they'd be switched off immediately and continuously until the abusers went away. They would NOT be taking over OUR facilities!!

Roy,
Thanks for the audio. In the weeks since this QRM came to light, with the help of recordings from users, we have found the club whose repeater audio is being retransmitted over AO-92. I do not believe this to be intentional. Despite the coincidence of frequencies involved, I also do not believe it to be a third harmonic. The audio is too clear, the signal is too strong, and repeaters have too much filtering for that to be happening.
I reached out to the board of directors and the repeater trustees, sent links to the audio including callsigns and their net ID. I explained that based on experience that this was likely someone crossbanding into their repeater with a poor choice of UHF frequency, and we could use their help in finding the QRM source, and my goal was to educate and remove it, not point fingers and place blame. The responses ranged from virtual shrugs, to claims of atmospheric conditions, to "there must be something wrong on the satellite end." A few suggested going to the repeater site and listening on UHF while the repeater is active, which is a pretty good idea. Supposedly they would make announcements about it on their nets.
I haven't given up on getting the club to help us find the QRM, but we may need some more convincing. I'll send the new recordings and ask again. Meanwhile, Is there anyone in the Gloucester, MA area that would like to do a little foxhunting for AMSAT?
73, Drew KO4MA AMSAT VP Operations
