Hi Martin, I have a report from ZL1TKL in Tokoroa via ZL1MO of possible UO-11 sightings. Times agree with NASA set #5. 6th March: 0849 UTC strong noise heard on 145.8227 brg 140 dg T. 0853 brg 120 dg 0856 brg 115 dg - a burst of high speed cw or tlm heard, but very weak. Lasted about 10 secs over 50 sec. period. 1026 some noise detected, 1031 noise heard, 1035 noise & 1037 much weaker. 8th March: Freq. 145.8231 at 1148 UTC - short period of about 1 minute, heard weird cw or tlm. ZL1TKL station: Rx is IC260A with B108 preamp. Ant is 23 elements horizontal with est. 16db gain. I have asked that he monitor and record any further sightings. If any uplinking required from S. Hemisphere, I can make arrangements for an EME station to help, especially on 435 MHz. Vy 73 de ZL1AOX.

No further commands have been accepted from the Guildford command station and commands from Los Angeles on 1.2GHz have not been successful either. A major source of hope has, however, been reported from Australia, where a NASA tracking station has reported hearing signals on 145.825 MHz at the times when UoSAT-2 was expected. These signals appear to centre around the correct frequency and exhibit the correct doppler shift, although we would expect modulation other than the steady carrier or rasping sounds reported. We would appreciate other well-equipped stations listening on the Oscar-11 downlink frequency for any possible signals. A record of doppler and frequency measurements, together with times of signal, from another station outside Australia would be especially conclusive. Attempts are being made to organise a large listening session at an installation in the U.K., however this is unlikely to take place for up to a fortnight. Since any concrete signal reports from around the world will be positive evidence that Oscar-11 is still alive - if silent - we are still eagerly awaiting your efforts. Roger University of Surrey.
