[Skimmertalk] Barking up wrong tree ? Flex and CW Skimmer Alignment (again!)

[Pete Smith N4ZR]

Thanks for reporting this, Andy. I don't think it is the RBN that's off, 
because each RBN station independently makes its own reading of the 
spotted station's frequency, and we don't tamper with that at the 
server.  We do dynamically check spots made by each station with a 
complex dynamic network of reference stations (also on the RBN), and 
quickly notify anyone who is off-frequency by more than +/- 0.2 KHz.

I suspect this is something in your Flex setup, but I can't begin to 
guess what it might be.  Have you talked to VE2WU? Marten has a Skimmer 
running on his Flex, with no big frequency discrepancies.

ARC V6 or VE7CC DX cluster node.
