Re: [Elecraft] FW: K3/KPA500/KAT500 SWR problem
I doubt your problems are because of the firmware, but the answer about the best version of firmware to use is to always load the latest production version. Beta versions can be useful if you are experiencing problems that the beta release corrects. Remember that beta versions are usually OK to use, but there are made available so a large number of users can report any problems they experience. If there are no problems reported, that beta version will be advanced to production status. OTOH, if there are problems reported, that beta version will be replaced by another beta with those problems addressed. 73, Don W3FPR On 12/19/2014 10:31 PM, Va3ied wrote: I just bought the tuner and am having the exact same issues on 80 mwhat veh of firmware works best? __ 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 Message delivered to arch...@mail-archive.com

Re: [Elecraft] FW: K3/KPA500/KAT500 SWR problem
In regards to proper grounding etc.: I think it is safe to say that K3 owners have a very good grasp of what is needed to construct and operate a proper station - safety and RF wise. 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.

Do you have coomon mode chokes on you feed lines?

Re: [Elecraft] FW: K3/KPA500/KAT500 SWR problem
Everything in the shack is grounded to an aluminum bus bar across the back of the operating table which is tied with #6 solid copper to the same point as the tower and AC Main grounds. Just for reference, the antenna is a 260ft OCF Inverted Vee at 75 ft using a Balun Designs #4115ocf 4:1/Choke combination balun. Coax shield is grounded at the top and bottom of the tower.

Re: [Elecraft] FW: K3/KPA500/KAT500 SWR problem
Hmmm, An aluminum bar tied to a copper wire! Be aware that there will be oxidation at the junction point due to dissimilar metals unless special bonding is used to slow (but not stop) the oxidation. Just something to bear in mind. 73, Don W3FPR On 12/30/2013 3:23 PM, KD0Q-Glenn wrote: Everything in the shack is grounded to an aluminum bus bar across the back of the operating table which is tied with #6 solid copper to the same point as the tower and AC Main grounds.

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