[net.columbia] W0ORE/Challenger heard at KA9Q

karn@petrus.UUCP (Phil R. Karn) (08/02/85)

SSTV signals were copied at KA9Q from W0ORE aboard the space shuttle
Challenger on two consecutive passes this afternoon (approx 5:30 and 7:15 pm
EDT). With a KLM-14C and GaAsFET preamp, signals were good, but not overly
strong (i.e, full quieting, but not pegging the meter). The signal is FM at
145.55 mHz and consists of slow scan television interspersed with the
tone CW ID "W0ORE/CHALLENGER".

Based on antenna pointing and doppler, tracking is about 1.5 minutes behind
predictions based on the last set (set 5a) so it ought to be usable at least
until a possible orbit change takes place tomorrow.

As with the STS-9/W5LFL flight, PLEASE avoid any and all transmissions on
145.55 mHz!
