A strange subject, but this one has me baffled. I use the K3 with an Icom AH-4 tuner (tuning manually initiated) on the roof above me and below the centre of a long doublet. I've used this configuration with several radios over the last 5 years or so and it's never given me grief.
I was on 30m cw, swr about 1.1 when suddenly I noticed my output drop from 100W to about 40W and the swr had risen to 4 or so. I hit the little button on my homebrew unit and the AH-4 retuned, but still with a high swr. The odd thing was that it was clear that as a result of this that the other station could no longer hear me. We were about 589 both ways so a 3 or 4dB drop in power would not cause that. I am wondering if I was transmitting somewhere else, and not on 30m. I changed to other bands and they all tuned fine. Went back to 30m, still the same apparent high swr. Then as suddenly as the problem had arrived it departed. As I was sending a chain of dots in frustration, the swr dropped right back down to just above 1.0 _without_ me having to initiate the tune- and that's what I don't follow! Hope that makes more sense to someone than it does to me. I'm really enjoying the K3 and even my wife prefers it to the K2 or TS-480, as she derives pleasure from spinnning the vfo whilst on the telephone at my desk! She still thinks the IC-7400 was prettier though! 73 Stephen G4SJP _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
