Hi Bob, Yes me and Scott K4KDR has observed this both with NO-84 the past few days. Here is a video Scott has on youtube of NO-84's 70cm PSK31 downlink acting crazy https://www.youtube.com/watch?v=8XqcUNJumSE . The 70cm downlink has been either a ticking carrier, not transmitting at all, or will transmit properly for a few seconds before going crazy again. I hope this is not the last we hear of the PSK31 transponder as I have really enjoyed it. The APRS downlink with the beacon telemetry has been observed by both me and him as either off completely or on for a limited a time. I hope to see NO-84's condition improve soon and to see the launch coming up in a few weeks of NO-84s replacement, PSAT-2 on the next Falcon Heavy Launch!
