RE: AO-51 downlink frequency high?



Answering my own question...

Discovered that my PC's clock was about 2 minutes fast...  So at the 
predicted TCA, where doppler whiplash is greatest, the PC thought I should 
be quite a bit lower than it really was.

I copied a nice pass of AO-51 this morning, but noticed that the downlink 
seemed to be about 10khz high in frequency, after accounting for doppler.  
Has anyone else noticed this, or has my radio (Yaesu FT736R) drifted a whole 
bunch suddenly?

An earlier pass of the ISS seemed about right, and I just heard a pass of 
FO-29.  The beacon may have been a little high, but it didn't seem to be off 
that much.
