The UOSAT h.f.beacons experiment

University of Surrey amateur scientific satellite, UOSA T carries a set of phase related beacons on 7, 14, and 29 MHz enabling experiments to be carried out trans-ionospheric propagation at the four frequencies beacons, which deliver 100 mW each, are synthesized the 7 MHz master oscillator and combined into one two 2-5 m monopoles tuned against the satellite body 15-metre boom. Modulation is by on/off carrier and be routed from the telemetry system or the primary spacecraft computer.
