We now have heard 4 of 5 transmitters from our 3 spacecraft all still in a close cluster:

* PSAT packet is OK but WOD not working (no digipeating for users yet) * PSAT PSK31 downlink is ok [remember, it is FM!] * BRICSAT telemetry has been heard but is cycling OFF due to low power * BRICSAT PSK31 downlink (also FM) has also been heard barely (when ON) * USS Langley not heard

PSAT CPU shows the 4 day-fail-safe backup reset circuit is not counting down, so we have lost this (1 of 3) fail safe backup RESET capabilities. Bad line of code already found. But cannot change it.

PSAT is not properly reporting WOD data and S#... STATUS packets are being bundled until 255 byte packet length is reached and then it all comes down at once. Noone has captured any of these long packets. Please try with PASSALL ON so that you can receive partial packets.

Awaiting permission from BRNO University to authorize HF user uplinks on PSAT PSK31.

BRICSAT PSK31 transponder is on identical frequencies as PSAT's. You can tell them apart because one has PSK Telemetry on 315 Hz and the other is on 365 Hz. Both on the UHF FM downlink 435.350 MHz

We'd LOVE to hear from USS Langley, and we'd love to capture one of those long WOD packets from PSAT. Our ground station is only getting a few packets compared to some submissions from others. Keep it up.
