[time-nuts] BG7TBL FA1 frequency analyzer

[Christoph Kopetzky]

This would be an interesting compare.
I want to compare the FA1 and the TSA3011 if I am back in office and 
have both in my hands...
But I really do not want to buy unnecessary tools...  So if someone has 
done this it would be nice to read about that.

Mark, do you have also a TICC?

best regards

Chris
