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
