[Elecraft] K3 6m pre-amp

[Stewart Baker]

My 6m setup is not the greatest. I have a beam in the garage, but 
to put that up means moving the HF antenna, so it will have to 
wait for the better weather.

Yes, I had just tried the ant vs dummy load comparison. The noise 
level increases with the antenna  connected, but whether that is 
due to band or local electrical noise I can't be sure.

It is probably that I have got used to seeing a significant noise 
reading on the S meter on the bands below 30MHz !
