The FM transponder was active on BY70-1 for the passes over North America this morning. K4KDR reported hearing my call on the pass around 1540 UTC, but I did not hear myself. On the 1709 UTC pass, I worked AC0RA and heard AA5PK.
The signal is strong, but the uplink seems to require precise Doppler tuning. I was only able to get in cleanly when tuning for Doppler, starting at around 145.917 MHz near AOS and tuning up to 145.923 MHz near LOS. An FM only radio with only 5 kHz steps may not work well for accessing this transponder.
There was also a clear SDR delay on the downlink signal which makes things interesting and it seems to require a bit of power to break the squelch. I was using about 30 watts on this pass.
Equipment used was 2 FT-817s, a High Sierra Microwave preamp, a Microset VUR-30 amplifier, and an Alaskan Arrow antenna with the top section removed (8 elements on 70 cm and 3 elements on 2 m)
Unfortunately, the satellite's life is destined to be quite short due to the incorrect orbital insertion with a very low perigee. The 2016-083A keps from CelesTrak's TLE-NEW.txt file seemed pretty accurate.
I have posted a recording of the pass. Skip ahead to about 2:35 of this recording:
On the 18:45utc pass, I heard KO6TH very loud and clear on 436.200, but was unable to find the uplink frequency.
