The first test of the FUNcube-1 (AO-73) SSB/CW linear transponder took place on Friday, November 22. The transponder was successfully commanded on at 10:49 UT and at 10:51 GB3RS successfully transmitted through the inverting transponder using a pair of Yaesu FT-817 transceivers and an Arrow dual-band antenna.
A two-way contact was then made between GB3RS and G0AUK who worked each other at 10:53 UT. Both stations were operating from the Bletchley Park car park each running 5 watts PEP to Arrow antennas.
FUNcube-1 carries a 20 kHz bandwidth transponder for SSB and CW communications. To reduce the Doppler shift the transponder is inverting meaning that a Lower Sideband (LSB) signal on the uplink comes out as an Upper Sideband (USB) signal on the downlink.
Testing and analysis of the telemetry data from FUNcube-1 (AO-73) is continuing.
Thank you to all stations who have provided telemetry so far. More telemetry data is needed to enable the FUNcube team to characterise the satellite.
The FUNcube Team hope to do further transponder tests possibly Saturday, November 23.
