Reception of the HO-68 (XW-1) satellite beacon using the Funcube Dongle receiver and an Arrow II hand-held yagi antenna. Quisk software defined radio receiver running on Ubuntu Linux 10.10 64bit.
I was located indoors pointing the Arrow out through the window (and Doppler tuning with left hand, hence the high pitch 😉
The peak was around 52 deg elevation, range 1400 km. The CW beacon transmitter is 200mW RF.
This recording was made on Saturday, May 5, 2012 using the AMSAT-UK FUNcube Dongle and Gqrx SDR. It shows very strong FM transmissions on the FO-29 linear transponder which could be from Spain or Portugal. The topic appears to be chocolate. Alexandru says – If you know who these people are, be sure to send them a QSL card!
The use of FM on a linear transponder satellite reduces the lifetime of both the batteries and the transponder itself.
