Re: [Elecraft] K2 internal keyer problem
I will do more testing. The auto detect is off, and I have good baluns/chokes on both of my antennas. It may be that I'm too close to my new elevated 40 vertical antenna. -- View this message in context: http://elecraft.365791.n2.nabble.com/K2-internal-keyer-problem-tp5385342p5418371.html Sent from the [K2] mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K2 internal keyer problem
Mark, That has to be either a firmware glitch (not likely), or the result of RF-in-the-shack causing it. The internal keyer routines in the firmware have been in place for a long time, and this is the first report of that behavior that I have heard. If it were a firmware problem, I would think others would experience the same thing. Try operating into a dummy load and see if you can produce it. If not, then suspect RF in the shack. If that is the case, the cure is within your antenna system. If the behavior is band dependent, then it is caused by RF being where it should not be. Do you have effective current baluns on your antennas? It is possible that the power level produced by the K1 would not cause any indication of a problem, but the higher power of the K2 might cause the RF problem to be noticed. 73, Don W3FPR ve7ymm wrote: I finally finished my k2 a couple of weeks ago, and it seems to be working fine.

I don't have this problem with my K1. It occurs rarely, perhaps once in a half hour of sending. I can't reproduce the problem at will. Any suggestions?

Re: [Elecraft] K2 internal keyer problem
I have seen this on occasion with my K2. Occasionally I get a very long DAH when I key as if I have mis-keyed. Tap the DIT paddle and all is well again. I only run 5W so I don't think it is RF, I suspect a bug in the firmware. But so infrequent not to worry about. 73 Dave G3YMC K2 #2498 -- View this message in context: http://elecraft.365791.n2.nabble.com/K2-internal-keyer-problem-tp5385342p5386476.html Sent from the [K2] mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K2 internal keyer problem
This sounds like the K2's auto-detect feature, which allows connecting both paddles and a straight key or computer, along with a couple of diodes, at the same time and sending from either. If the paddles are squeezed at exactly the same time, it looks like the straight key to the circuit. If I remember right, it can be avoided by choosing normal rather than auto in the input menu.

I think you might be right Peter. I don't think I had ever looked at that setting, and the way it works it is hard to see what it is set to. ie if you press DISPLAY while at the INP menu setting it toggles it rather than just displays it. I THINK I have it OFF now, so will see what happens.
