the radio when you add the second receiver. I have all of a 2nd RX but not this DVR board that I am sure the user did not know to remove when they removed the 2nd RX from a radio. If anyone has extras of the above or parts radios I might be interested. Thanks -- George Fremin III - K5TR geo

I posted here last fall when one of our K3 radios stopped putting put any power during the last few hours of the CQ WW CW contest. For many reasons I am finally getting back to looking at this failed radio. I swapped in a known working KPA3 Rev C module and the radio works as expected now on

Re: [Elecraft] Recommendation for Microphone for K3s?

There is nothing wrong with Heil micophones. I used them for many years. What I did not like were the headphones so I would mount the HC-4 and HC-5 booms off of the broken headphones onto headphones that I liked to wear and listen to. Over the years I tried many different ones. AKG-K240, Son

[Elecraft] Deaf K3

I turned on the K3 this morning and it is very deaf. hooking up and XG-3 to it shows it to be very deaf on ant 1 and ant 2. It seems to hear ok or maybe even normally on the RX any port. Is that enough to make guesses as to what has failed? -- George Fremin III
