    "content": "We also experienced a good bit of QRM on the the AO-92 downlink towards \nthe end of the pass previous to the one mentioned in the subject line \n(~1450 UTC) during our demo yesterday.  We had the same problem (though \nless of an effect) the day prior during testing of our setup, but \nslightly offset in time (the QRM showed up just before the 7/11 ~1515 \nUTC AO-92 pass).  Definitely had the doppler shift features indicating \nit was another satellite in the 2m band and close to the AO-92 \ndownlink.  On the 7/12 1450UTC pass, the interferer was strong enough \nthat it 'edged out' the AO-92 downlink and was captured by our doppler \ncorrection loop (ending the demo, but that was OK because we already got \na few images direct, and then I jumped to the website to show them more \nimages recovered by the community).\n\nWe used GNU Radio married to FoxTelem for the passes.  I have the \nrecorded IQ files for both passes where the , but haven't had a chance \nto go back and investigate what exactly was going on or hunt for which \nbird was the 'culprit' though now it seems CAS-4B is a good \nsuspect......If I get a chance I'll play around with the flowgraph and \nsee if I can manually tune in the AO-92 signal and filter out the \ninterferer to see if I can recover any more telemetry/camera pieces.\n\nJust offering another data point and similar experiences...\n\n\n\n-Zach, KJ4QLP\n\nResearch Associate\nAerospace Systems Lab\nTed & Karyn Hume Center for National Security & Technology\nVirginia Polytechnic Institute & State University\nWork Phone: 540-231-4174\nCell Phone: 540-808-6305\n\nOn 7/13/2018 4:29 AM, John wrote:\n> Hi Hal,\n>\n> I too have an FT-847, however instead of programming satellites into the memories, I let SatPC32 'get it right' for me, along with tuning for doppler and handling tones etc. It's a far easier solution.\n>\n> Otherwise, you could go through the AMSAT OSCAR Status page, and grab all the birds you're likely to want to work from that list.\n>\n> 73,\n> John (XLX)\n>\n> -----Original Message-----\n> From: AMSAT-BB <[email protected]> On Behalf Of Hal Dale\n> Sent: 12 July 2018 19:09\n> Cc: [email protected]\n> Subject: Re: [amsat-bb] AO-92 1626UTC 7/12 PASS CAMERA TEST\n>\n>   I have a FT847.
