[amsat-bb] Re: AO-7 is not OK

Hi Piraja,

Yes, I made similar observations. If the CW is active on 70cm you can hear sometimes a very strong deviation in frequency. The CW beacon partly not decodable. I agree with you it could be an effect by low batteries or due heavy usage. See some graphs here: http://www.dk3wn.info/p/?cat=21

Hi gang!

There is no battery left in AO-7. All the current is generated by solar panels and the only "power buffer" is the capacitors in the regulator board. This may cause the voltage drop that also affects to output power and shifts oscillators. The solar panels are quite old too...
