Re: [Elecraft] Arc Fault Detector Woes
Some yers ago I had a problem with the arc fault detectors tripping when transmitting. After contacting the ARRL to see if they were aware of any problems with these devices, it turned out that some of the new Eaton units were overly susceptible to RF. They put me in touch with Eaton who replaced all of them in my home. This resolved most of those issues.

Re: [Elecraft] K4 Ergonomics etc
Very good review and information Doug. Thanks for taking the time to do it. I too will be ordering a K4, probably in the second production run. I may wait until the super het version is available.

Re: [Elecraft] Silent power supply for a K3s
I have an Astron RS35 power Supply purchased in 1991. There was a period where I didn’t use it for ten years. Now it’s in use daily and so far it continues to be totally quiet.

Re: [Elecraft] Will there be a K4
I am in the same boat. I really want to join the Elecraft Family, but the K3 is aging and I feel a major upgrade must be on the table. Icom, Flex, and now Yaesu have recently introduced new high tech models. On one hand I am ready to purchase a new K3s, but will be very unhappy if shortly thereafter an upgraded new model is introduced. Therefore, at least for now, I wait.
