Regarding Canada's Space Program, did you know that Canada's oldie satellite 
Allouette-2 is back to live???, or at least its transmitters.....

While I was monitoring the 136-138 satellite sub-band a couple of months ago 
with a RTL2832U based cheap SDR dongle I founded weird doppler shifted 
signals not matching any known transmitting satellite. After reporting it on 
the HearSat mailing list and posterior confirmation from Mike Kenny in 
Australia the best match was Canadian old satellite Allouete-2 launched in 

It is amazing how solar panels, antennas and transmitters stages are 
functioning after 48 years!!! It can be heard on:
136.076 +- 2 KHz with high instability, strong.
136.589 with unmodulated sub-carriers, weak.
136.981 Continuos Wave.

All three transmitters are alive after many years. It seems that due to some 
unknown reason it started to transmit again. May be the very same UFO which 
un-plug the batteries from the AO-07 bus ran across that oldie historical 
satellite and push the "ON" button HI HI HI HI HI!!!

All the bests and 73,
