Hello Mak and bb-readers,

Same observation here about yesterdays AO-7 signals, extremely weak. I 
heard your CQ and answered it but then lost your signal completely. 
That's why I didn't log the QSO to AO-7 website.
Does anyone have any idea what could be the current TX power of AO-7 
nowdays, as it uses only solar panels? I assume it is not anymore 8W on 
mode B/2W on mode C, the  difference is 6dB and that shouldn't drop 
signal levels from "usual" S7-9 to barely heardable...
You guys are much more experienced AO-7 users, feel free to correct me 
if I am wrong :)

Mika, OH8MBN
