FREQ is 437.605 (corrected)
Object is 44355
I captured objects via VK6HAM at 151929 to 152812 for PSAT2 and for USNAP1 from 151803 to 152711 showing USNA P1 about a minute ahead of PSAT2.
It is only alive for about 60 to 70 minutes when in the sun apparently by looking at the T# telemetry count.

Standard 9600 baud AX.25. No special software. Just need raw packets.on 447.605
PSAT2 and USNAP1 were delppyed together and have identical external shape and so should be in same orbit, but due to mass differences, USNAP1 should be LEADING PSAT2. We need to know by houw much. Since PSAT2 is likely object 44354, and 44355 is very slightly leading (by 1 minute) that could be it.

So what do we need to copy the downlink data?? Is there an app or is it straight ax.25 packet???

The VHF telemetry shown here has only bus voltage. The digipeater is OFF and will remain off until we find out what happened.
In the mean time, we need all the capture we can get of the 9600 baud downlink on 437.605 MHz +/- Doppler. There is a beacon every 30 seconds.
