[amsat-bb] Fwd: USNAP1 lives! - capture UHF data pse -UPDATE

[Robert Bruninga]

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.
