[Elecraft] 10 MHz external reference

[Gary Smith]

Udo & Kevin,

Thanks for the reply. I hadn't researched any of the options, I 
thought the K3EXREF was all I needed. Now that I have a better idea 
what to look for, I'll find something. I just need to be sure it fits 

what the requirements are.

I'm surprised to find almost all the sources are from China. I know 
they are trying ever more to make better products but something as 
precise as a 10 MHz standard that will be connected to my K3s, 
concerns when me buying from an unknown manufacturer. QC is always a 
concern. Sure wish there was an affordable kit with the proper 
connections that was available.

If anyone has a 10 MHz reference signal source that works fine with 
the K3 & is excess to their needs, please contact me off list.

Thanks & 73,

Gary
