Re: [amsat-bb] Uplink frequency of FM satellites
I had a little time to test just now before AO-85 got too busy. I was trying to change a lot of things but at the time of the test, uplink 435175 LHCP and LHCP on the downlink was the best. Of course a short time later RHCP was better. "Tumbling Tumbleweeds" Ron W5RKN

Thanks Paul, I had heard that AO-85 was lower than the nominal, 435180, and did a short test yesterday. 435180 gave acceptable audio and 435168 produced distorted and noisy audio. I’ll try 435172. The satellite is so busy it’s hard to get a good test in. Ron W5RKN From: Paul Stoetzer Sent: Tuesday, August 09, 2016 4:08 AM To: Ronald G.

There's nothing to suggest that 145.850 isn't it for SO-50.
Measurements after launch showed that the uplink for AO-85 is about 435.172 MHz.

Is there any good current data on the actual center uplink frequency at the satellite of the current crop of FM satellites such as SO-50 and AO-85?

Ron, if you use SatPC32 you can use the "Upl. Calibr." controls in menu CAT to correct the uplink frequency in steps of 10, 100 and 1000 Hz (while you are transmitting) to check which uplink works best. The controls are disabled with FM-Sats by default. To enable them also for FM sats click the "V" control to "V+".
