On January 27th, Brad Schumacher, W5SAT, reported copying his CW signal weakly via the RadFxSat-2 transponder. On the morning of January 28th, AMSAT Engineering and Operations confirmed these reports and determined that RadFxSat-2 is partially functioning, though signals are extremely weak. AMSAT thanks W5SAT for his report.
We also appreciate those who joined in determining whether they could detect their own or other signals in recent passes today.
At this time it is essential and we ask you: Please do not attempt to transmit through the transponder until further notice. This is very important to the next steps we are taking now.
The next crucial step in evaluating the condition of RadFxSat-2 is to determine whether or not the 1200 bps BPSK telemetry beacon is operating and, if possible, copy telemetry from the beacon. We ask that everyone with 70cm receive capability listen to the beacon frequency of 435.750 MHz (+/-) Doppler, upper sideband (USB). Use FoxTelem with your receiver in order to tune and capture any telemetry you can. Also make sure FoxTelem is set to “Upload to server” so that we receive your telemetry data. If you capture a good IQ recording on SDR, please send a detailed description of your recording to foxtelem at amsat.us. We may respond with a request for your recording and details on how to transfer it to the AMSAT Engineering team. Please understand that keeping the transponder clear is essential to putting all power and attention to the beacon telemetry.
Two-line elements (TLEs) are available in AMSAT’s nasabare.txt distribution at https://www.amsat.org/tle/current/nasabare.txt. Available data suggests that RadFxSat-2 is OBJECT M from the Virgin Orbit LauncherOne launch, NORAD ID 47320, international designation 21-002M.
We thank the amateur satellite community for their perseverance and assistance while the AMSAT Engineering and Operations teams work to understand and resolve the situation with RadFxSat-2.
