Here is a strange problem that seemed to be intermittent last night and now has disappeared.
Last night in the 160 contest, when I turned on the subrx, I lost transmit power. (It had been fine up until then.) I was operating at 100W with (or without) the ATU into an okay ~1.5:1 load. When I pressed the SUB (or did it from software), the SWR would go up to ~6:1 as read on an external meter and power out would be about 3 watts. Yes, an external meter said that the power out was about 3 watts and the SWR was now high. To me that indicated I wasn't transmitting on 160M anymore, although the K3 display still read 1.8xxMHz. Either I was suffering from lack of sleep or something was strange. I only have one antenna, there is no switching. I was on ANT 1 (or else the meter wouldn't work). After going back and forth from the sub rx on and off, I power cycled the radio, still no change. I just decided to not use the sub rx to get on with the contest. A little later I tried it again and could not reproduce it. It probably had something to do with the frequency I was on (high up in the band) or the lack of sleep. Any clues? ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
