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
Small correction below.

If Howard is correct on the output level, it's a little low for the
K3EXREF's input. From the manual:
Connect the external 10 MHz signal source to the K3 rear panel REF.
connector. The 10 MHz source should have a signal level between +4 dBm
and +16 dBm, nominal. For square wave sources, 2VDC to 3
This is an inquiry I sent to Elecraft, along with their response:
I’ve been considering adding the K3XREF to my K3. Can you tell me if the device
listed in this link is a suitable 10MHz source? (Re: Navsync CW12-TIM GPS
