As it had been over 10 years that I had heard this satellite I decided to give it a go.
Using the TS-2000 and a simple 14MHz dipol, no pre-amp, I was able to hear the beacon.
Quite weak, but audible. Frequency as in the report; 29.3156MHz (assume this to be Beacon 1).

On my website I have placed an mp3 recording and some 'waterfall' graphics:

You hear & see the beacon being switched on (~2 seconds) and off (~3 seconds). Also you
hear & see the beacon 'tuning in' to the correct frequency every time it's switched on.

Looking forward for your comments/feedback/experiences !
