Hi from David EA4SG.

I send this short AO-73 SWL report hoping it could be useful to the 
AO-73 Command Team.

In the lasts two orbits (#7434 and #7435) over my QTH located in 
Colmenar Viejo (Madrid) locator IN80CP, the bird reached AOS with the 
transponder ON as expected, downlink signal was slightly weaker than 
usual, modulation was quite distorted (similar to the one we get from 
AO-7) and transponder switched off exactly at the expected "ilumination 
time" (20:31UTC  and 22:08UTC).

I was also listening to the telemetry and it was affected by the above 
mentioned distorsion too. I didnt try, but I am sure that this 
distortion will make telemetry harder to be decoded.

Best 73s de David EA4SG
