I have a very early K2 that I use for field operations. It functions as an emergency communication source for serious backcountry trips (multi-day wilderness whitewater rafting, etc.). I am finding that a power output of, say, 20W would be desirable as a compromise between more reliable communication and battery usage. My K2 puts out about 14W. Thus I ask the experts: has anyone revamped the TX RF stages sufficient to put out 20 -25W output? Yes, I know this amounts to only a dB or two. But it can be the edge needed in very marginal conditions.
Second issue. The K2 has always been on the low side for RX audio. Being no longer a young buck, my hearing is not perfect any more. Is there a known mod to add 5-10 dB to the audio chain without drastic distortion? Presently I take along a Radio Shack headphone 3-way amp that gives about that. It works fine but is yet another piece of gear to bring along and doesn't feed the internal speaker. When I had a KX1 (now sold) it had been modified to have a second audio amp chip put in and it really helped. Has anyone done a similar thing for the K2? I am not a EE by any means so would prefer to follow known modification paths. Anyone? -- 73 Allan K7GT ______________________________________________________________ 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
