Good evening, I have been enjoying my newly-built "K2 twins" over the last few weeks (K2 #7225), but so far, only on 20M and 17M - there's been no propagation on the higher bands, and I'm currently antenna-challenged on 30M and down. I measure full power out from the KPA100 with my LP-100, and the KAT100 works well into a fairly marginal antenna. I'm getting good audio reports using the MH2 mic.
1. Four times, I've seen the LCD go into the "power adjustment" screen just as I start to adjust the frequency. As I continue to turn the knob, the display goes immediately back to frequency. I'm using an after-market CNC'd aluminum knob with a "bearinged" dimple. It's the same diameter as the stock knob, but a bit heavier, and it is just rubbing the felt washer. I wondered the first time this happened if this was maybe a static discharge as I touched the knob, but I didn't feel or hear anything. The last couple of times, I thought it might be a mechanical issue due to the interference of the encoder and front-panel board(s). Any ideas? 2. I set the filters with the N-Gen and Spectrogram, using the instructions on Don's website. The filters work as I expect them to, but at times there is a loud, high-frequency hiss on SSB filters 2-4 that is rather annoying. Can I just play with the position of the signal in each pass-band to help this, or is there something else I should look at? The signal I want to hear is audible in all four filters, so I think they're set properly - I just want to improve them if I can. 3. I am using an external, amplified speaker, made for mobile use, because the K2's audio seems a bit low. Is this normal? This solution is fine with me; I just want to "hear" what other folks have experienced. Thanks in advance, 73, Jim KO5V ______________________________________________________________ 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 Message delivered to arch...@mail-archive.com
