[Elecraft] Low power out on 10M

Yeah, I know this subject has been kicked around for a while, but none the less. When I built the K2, I had no trouble getting the 10W out on 10M. 1) I have rewound T2 and elevated it above the board 1/16 inch. 2) Band Power at W6 Measured output.

Greetings from a newbie K2 builder. I am currently building #5390. Into phase 3 now, somewhere in the early stage of the rf board. Don't get too much time for this detailed work and my xyl has made me clear out the spare bedroom in our apartment (aka construction area), as she does not seem to l

RE: [Elecraft] Cool Straight Key For Morse KB3NNP

Very cool indeed. I've looked at / longed for one of those keys, but it's a bit rich for my blood. Yes, let us know how it is. Diana should pick a time and schedule to be on the air. If she lets us know in advance, she night end up with a 5 wpm pile up. Now wouldn't that be cool. The tie to M

RE: [Elecraft] Low power out on 10M

I'm clueless but can offer an observation for you to laugh at and ignore. On 10 meters, -29.3 DBM yields 2.0 watts while -26.7 yields 5 watts. The change in drive level is about 3 dB which is twice the power so that looks like what I'd expect. On 20, the change is about 6 dB or 4x power and you

[Elecraft] mutiple XV daisy-chaining

So, how do you do it? I originally set mine up to use all BNC plumbing, tees and female barrels with a right angle at the end. This is giving inconsistent result, presumably because of inaccuracy in spacing and stress on the plumbing. Today we've been trying various combinations of stubs to the pl

RE: [Elecraft] Low power out on 10M

Jim, There are 3 stages of RF amplification in the transmit chain between the W6 jumper and the LPF, you will have to refine the search a bit - right now, all I can say with certainty is that the problem lies between W6 and the LPF. I would suggest checking all the components in the base circuit

[Elecraft] Another use for XIT: quick frequency offset for ATU re-tune

Hi all, I frequently use XIT as a way to quickly move off frequency to re-tune the auto-tuner. I just leave the K2's RIT/XIT offset control set fully clockwise (or counterclockwise). Then, when I want to re-tune the ATU, I turn on *both* RIT and XIT first. This is equivalent to moving the VFO

Re: [Elecraft] Tube Linear Amp design for basic K2

Wyn, I have an antique Hallicrafters HT33A with a PL172 tube, and I modified it so it will accept lower drive. Right now when I drive it with about 20 watts from my K2/100 in PSK31, I get about 400 watts out. That's a gain of 20 times, or 13 dB. The tube input is swamped with a 50 ohm res

[Elecraft] Frequency shift in old K2

For awhile, I've been experiencing a down shift of about 200 hertz, but rarely and randomly in my K2 serial 0063. It's enough to change the characteristic tone in the receiver and degrades from the filter settings. Any suggestions as to where to start looking? Doesn't seem to be temperature-depe
