[Elecraft] K3 - TCXO

[Dave G4AON]

I am often to be found monitoring one of the CW QRP frequencies and 
usually have the bandwidth set very narrow to minimise band noise, so 
it's nice to know that if someone calls right on the  frequency I will 
hear them. I have the KTCXO3-1  TCXO and find it remains within 20 Hz at 
50 MHz when checked against the 5th harmonic of my 10 MHz GPS derived 
standard. That is better than specification even without the awaited 
firmware correction feature, but there again it's not being measured 
over more than a couple of weeks and is operated at room temperature.
