[Elecraft] Using RadioSport headset standard mic with KX3?

2014-02-28 Thread Les Gasser W9XC
this because the same mic works great with my Flex 6500, and I'd imagine the KX3 could accommodate a range of mic levels as great as the Flex can. Any help appreciated. - Les Gasser, W9XC __ Elecraft mailing list Home: http://mailman.qth.net

If Ralf's hypothesis is correct, another approach (besides RX-shift) might be to turn on the RX ISO menu item. Doing that helps reduce the radiation of the local oscillator. - Les, W9XC Hi Klaus, I tried to provoke some AM breakthrough with my active antenna in april and used a very strong

Ron, this announcement led me to the radiomarine.org site, and from there to the magnificent on-air recordings of the coastal stations and marine operations. What a fantastic historical resource - not to mention a superb trove of real-world (and often hand-keyed) CW that is great for CW practice,

2 things: 1. You can turn the K1 output power off completely (Pwr = 0) by tapping BAND/DISPLAY when in the Out Menu. Tapping BAND/DISPLAY a second time turns power back on. 2. Because of paddle design, the dit and dah sides interact on some paddles when the paddle-to-contact spacing is set

Yes, it's the PA kicking in; here's a small study I did earlier this year: http://w9xc.net/articles/k3-measured-power-consumption.html Other than the bump at the PA transition, the power increase per output watt seems pretty linear. The interesting implications come when running from an
