AO-7 operators.

I noticed that AO-7's TX oscillator was 10Khz higher than "normal" (while in 
mode-B) on orbit 34911 at 16:10 UTC today, Sunday 09.05.04.

There were no other reports on the resource page immediately after the pass 
but I know some stations work AO-7 without logging the QSO. I'm wondering if 
anyone else noticed this anomoly?.
I checked my equipment and tracking programs carefully but found nothing 

Four days ago the voltage was so low that even single CW characters were 
changing tone between about 700 and 1500 hertz. The day before yesterday the 
transponder was reasonably stable again
(Better propagation). I'm fully aware that the satellite needs a good dose 
of solar power to remain stable.

Today, according to my reckoning the satellite had been out of eclipse for 
several hours.
I've monitored or worked AO-7 everyday for the last 7 months but never seen 
this peculiarity before.

Can anyone offer a probable explanation?.
