My K2 will not give more than a few watts out on 40 meters when driving my antenna. Into a dummy load it gives full power. On 30 meters with a different antenna the rig is fine. I wondered if it was a problem with the rig but I saw some other things that make me think it's an antenna problem. The antenna is a ground mounted vertical fed with 30 feet of RG-213 to a Heath manual tuner in the garage. From there, RG -8x takes the signal all the way to the shack. I go to the garage with my MFJ analyzer and adjust the tuner for a match on my operating freq. I did this and got a 1:1 match at 7040. I then went to the shack and confirmed the same SWR at the rig. Hook up the rig, key it and the SWR meter shows very high SWR. Rig is generating hardly any power out. Recheck with the analyzer and SWR is fine. Hmm. I'm thinking the issue is power related. Could it be that my antenna system has a problem that only shows up when you hit the system with a few watts and doesn't show when the analyzer hits it with milliwatts? Last night I tried it again and noticed the resonant frequency had shifted from 7.040 to 9 MHz. I think it is time for an antenna / tuner / coax review. - Keith - _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
