Good point Don! That's why I use stainless steel hardware and ICE 602 copper/aluminum anti-oxidant paste.

I do, yet still went back over every last connector/connection/lug, etc. Everything is locked down properly here. No baluns, good coax, and everything is mechanical and soldered along the entire antenna routes. Yet, the problem continues. Perhaps the most disconcerting part is that my other auto tuners/rigs do not exhibit this difficulty. Perhaps the KAT500 is seeing something the others do not. The difficult part is never knowing when the tuner will take off and the fact that MANUAL selection does not appear to make any difference. I have been using MANUAL for a couple of months. I do not see that it has made any difference in occurrences. The instances of "run-away" are random and it is usually days between events.

Re: [Elecraft] K3/KPA500/KAT500 SWR problem
I experience this as well, only on 80 meters with the KPA500 in operate. Always thought that it was RF getting into the KAT500 sensing as I can usually back off to 300 Watts, force a KAT500 re-tune and continue. Glenn - KD0Q On 12/30/2013 07:59, Bill W2BLC wrote: This is exactly why I want to see this complete discussion in full view. It is a problem here also - occurring often and without any obvious cause. Putting the tuner in AUTO or in MANUAL does not stop it from happening. The tuner does not seem to understand the term MANUAL. My experience is from 75 meters - with no change in antennas - and will occur on oft used frequencies in the middle of a transmission. The tuner just suddenly decides it is time to make noises. I do not use other bands and the antenna is a dipole that present no problems to other rigs and tuners (read as nothing wrong with the antenna or feedlines, which have all been completely checked). AT the very least, I now know I am not alone with this problem.

[Elecraft] [K3] KAT3 Hiccup
The CQ 160M CW contest last weekend was the first contest for my K3 SN 4518. First time I've heard the fans kick in, same for the Samlex PS. And I have to say I am very pleased with the receive performance - with filter bandwidth set to 200 HZ and fine tuning, the band didn't seem crowded at all. Very few times did I have any trouble with adjacent signals. But I did have one scare. The KAT3 has always auto tuned my OCF dipole to a reasonable match. But about 7 hours into the contest I experienced a pop in the earphones and the K3 went deaf. The SWR was high and the KAT3 wouldn't tune better than 5.3:1. Thinking maybe I lost a leg off the dipole, I went outside and checked the antenna. All looked OK. I tested the antenna with another rig and a manual tuner and it seemed OK. Not knowing what else to do, I checked the OCF dipole on several other bands with the K3, and the KAT3 tuned to a good match. Then when I went back to check 160, all was well again. Needless to say, I was relieved. Went back to the contest and had no more problems. Anyone else ever experience anything like this? 73, Glenn / KD0Q __ 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
[Elecraft] K3 # 4518 is QRV
Hello Elecrafters, K3 #4518 arrived via UPS last Tuesday afternoon and made the first contact last night. The inventory and build took me about 11 hours over the course of 4 days with lots of stopping and starting. All the checks and calibrations went smoothly. The excellent documentation and quality parts made for an enjoyable project. "Good Job!" to the Subassembly Packers Ryan, Susan, Alex and Leony, and to everyone else at Elecraft that had a part in putting this kit together and processing my order. 73, Glenn/KD0Q __ 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
