I was fortunate enough to work CY9C today at 21:08:39 during a pass of AO-7. Great operator on the other end and great signals too. Heard him work quite a few prior to me as well.

Did the same thing when they weren’t busy on a XW-2C pass at 22:07:25. Even stronger signals.
Clayton, W5PFG, published the following table on the AMSAT-BB (He reported hearing my call to CY9C down in Texas):

I can remember back to the days of AO-6 and AO-7. One satellite in the sky, 4-6 passes in a day, calculations done graphically using the Oscar Locator and weekly elements sent via W1AW bulletin (no PCs or public internet back then).
Today the sky is jammed full of satellites, with a new one (EO-79) being turned over to amateur use as I write this.
The above is “The sky at a glance” output from the GPredict.exe program; showing satellites visible in my area between about 1 PM and 9 PM today. That’s 23 opportunities for me to work a satellite in an 8 hour window. I have worked all of those with simple equipment (egg-beater antennas with mast mounted preamps) — some, like FO-29, are much easier than others (like AO-85 which doesn’t hear me well, or AO-73, which can be difficult to locate one’s downlink on).
Being a satellite guy no longer means waiting half the day to make a contact or two. You can pretty much be sure there will be a satellite in view no more than every other hour, and often several in an hour.
The QSL rate for satellite operators is disappointingly low, even for those using LotW. This means it takes more time to obtain various operating awards.
Today, I finally qualified for the AMSAT Oscar Satellite Communications Achievement Award, which is 20 different states and countries confirmed. George, WA5KBH in Louisiana happened to be the 20th different confirmation on FO-29 SSB today. Thanks for uploading your satellite activity so quickly to LotW!

I have also been monitoring the telemetry from UKUBE-2 (Funcube-2).
With a satellite frequency of 145.915.7, I received packets with a frequency of 1627 Hz to 1288 Hz. This is a shift of 339 Hz (very close to the shift seen for AO-73). That puts the center frequency at 1457 Hz. This is pretty darn close to the sweet spot for 1500 decoding — an adjusted Doppler.sqf frequency would be 145.915.65.
With the packets captured today, I just broke into the top 200 in terms of data providers (clearly not many folks are providing data to the warehouse for UKUBE-1 if 338 packets uploaded is ranked at 193).
I’ve been watching AO-73 telemetry frequencies for the past few weeks. Today I noted that a satellite frequency of 145.934.8 produced packets captured between 1538 and 1168 Hz, or a drift over that period of 370 Hz. From this it appears a slightly more optimal frequency for my Doppler.sqf file would be 145.934.65, which would have produced packets captured between 1688 and 1418 Hz — pretty much centered around 1500 Hz.
Day and night, all HF bands are “Poor”
