[Elecraft] K3EXREF and NavSync CW12-TIM GPS Module

[Edward R Cole]

I was one of the beta testers on the K3EXREF.  I am using a surplus 
OCXO bought for about $45 on e-bay.  Its output was a distorted 
sinewave (appears to have strong second harmonic).  I removed the 
harmonic by running the 10-MHz thru a DEMI model 10-4 distribution 
amp that uses 10-MHz bandpass filters on each of the four outputs 
(which are 10 dBm).  The K3EXREF runs very nicely with this.
