Last week's ISS SSTV activity was a good way to see how my 2m DCA worked (hint: I was a bit disappointed). Testing your antenna in real world situations is difficult with satellites, because there are no signals around at will, like with terrestial beacons, of friendly fellow hams who want to test with you. The ISS activity provided a good opportunity to get at least a couple of reliable signals a day.
I haven't been very successful in picking up much with my 70cm DCA, yet. I'm not expecting miracles, but it would be nice to at least see some traces of something on the waterfall of my Airspy Mini.
So I was wondering, what are the strongest, most reliable beacons you can hear on 70cm that I can plug into Gpredict to track? So far I have come up with this:
LO-19 - 437.125 MHz - carrier, but continuous. I've heard this one. FO-29 - 435.795 MHz - haven't heard this one yet. Active? Athenoxat-1 - 437.495 MHz - CW ID and I've heard this one faintly. RS-30 - 435.315 MHz - still active? Haven't heard this one. Lilacsat 2 - 437.200 MHz - listed, but active?
Any additions to what beacons are active or inactive on 70cm are welcome. Both CW and FSK telemetry are fine. Cheers,

PSAT often has a FM downlink on 435.350 carrying the HF PSK31 bandwidth. It comes up whenever there is 10m HF PSK31 activity. SO, not guaranteed on every pass, but it does come up. Bob, WB4APR
