[Elecraft] Why is my K3 off frequency?

Tue Mar 23 09:18:25 EDT 2021

Maybe I am missing the point.  

While you may be off by 12Hz, not sure if I would feel that I want to participate in this Net if you are called out for that.

When I was brought into 6 meters I was told this was the Gentlemen's band.  
Most all the nets I participate in are within 100Hz at best.  
Also, I do recall when a current big manufacturer did not set there Bias correctly and we (somewhat) lived with it.

I still recall on 6 meters contesting when you ran across a buddy that you had not talked to in years, you took the time to chat with him to see how he was.
I hope that still exists!

Sheesh.

Tech support provided an adjustment solution for the transverter which  is beyond what I can do.  Will send it back to Elecraft when my K4 arrives.
