I'm happy to say that my XV50 (formerly fried XV144) came to life and has passed all of its tests. I need to get a trustworthy frequency counter to really get it tweaked up, but it seems to make full power, and hear well. As usual, the only real problems I had were in properly configuring the K2

Thanks Don, I'll test it as-is. The 2d connectors are all contacting clean metal, so it should be OK - at least in terms of noise. 73, Jim KO5V -Original Message- >From: Don Wilhelm >Sent: Dec 23, 2018 12:09 PM >To: Jim KO5V , Elecraft List >Subject: Re: [Elecra

Jim, I would have to ask the XV series designer, but he specified that those transistors be mounted above the board. Likely for LO stability, and better separation from the ground plane on the board. I believe it should work mounted the same way in the XV50. If you find LO instability, the

First, Happy Holidays to everyone, and thanks for all of the helpful advice over the past few months. I purchased a badly-built and fried XV144 several years ago (I got it really cheap). The builder had shorted leads 1 & 2 of T1 above the PC board, and during initial testing, I think that cause

DW, Do you also have the KAT2 installed in your K2? If you do, did your see the note with the K60XV that the KAT2 R6 value must be increased to 470 ohms? Also: The power knob does control the power output from the low power output jack on the K2. With the power knob set at full rotation, wha

Hello, I finally finished my XV50, got it debugged and working. Now there is one more problem/question. I setting up the configuration, I set the low power out of the K60XV to 1.0 MW. When I have everything connected, and operating, the display shows that the K2 is only putting our about 0.3 M
