[Elecraft] KPA100 Power Surge Advice

Advice would be much appreciated. I would start by saying that I am not very electronically skilled. The power suppy goes from the power supply to a KPA100 in a separate enclosure which I built from a kit, then to the K2 Radio. The KPA100 does not light up, no power. 73 - Larry(G0IKE)

[Elecraft] K2/100

I built my KPA100 14 years ago in a separate enclosure and it still works fine. I wonder if the upgrade kit would provide improved performance. Any feed back will be appreciated. Larry - GOIKE __ Elecraft mailing list Home: http://mailman.

[Elecraft] K2/KPA100

I have started to experience low power on 12 and 10 meters with my KPA100. I get 65 watts on 12 meters with a good SWR (1:1) and 35 on 10 meters with a good SWR (1:1). I initially thought of the low pass filters in the KPA100 but the schematic shows that this would affect 15 meters as well, and 15

[Elecraft] Noise Generator

No electronic background, but have successfully followed excellent instructions and completed KAT100 and KPA100 and have these working in an EC2 enclosure. Not bad for a guy who cannot tell the difference between a resistor and a capacitor! Now for dumb question. I would like a noise generato

[Elecraft] KPA100 Alignment

[Elecraft] KPA100 Problem?

I am not an experienced builder, but having purchased a ready built K2, I decided that the experience of building a KPA100 would be good for me. And everything has gone pretty well until I got to page 41 of the manual and conducted the tests. Most (J3 lead, Q1 and Q2, and J2) are fine and the

[Elecraft] Low Power ?

I wonder if my K2 (Serial # 2424 with latest mods and software) is set up correctly and would appreciate comments. Output power with CAL CURR set at 3.0 amps is as below. Increasing CAL CURR to 5 amps makes little difference. I know that the K2 is basically a 10 watt rig and I get more on som
