Hello,
This is to report that CO-55 seems to be stuck with a 100% duty cycle carrier on 436.825 MHz. The CW beacon was not operational during the 2013-02-22 02:07z pass over Northern California, instead a constant carrier was heard during the entire pass, maximum signal S8.
Receiving station: FT-817ND, AD6IW 25dB 0.3NF preamp, Arrow antenna, Arduino-controlled rotator, Orbitron tracking/doppler software
Not sure if this is a recent issue or not on this satellite. Is anyone from Tokyo Institute of Technology on this list?

Hi Bernard
I can confirm that CO-55 has a problem on the pass at 0829 UTC at QF22IG. It is transmitted CW (436,836 MHz) but very low in modulation so appears almost as 100% carrier

Hi Bernhard, It has been like that for a very long time. Still it is easy to hear :-) 73 OZ1MY/Ib
