Hello James, Could you please let me know when you bought your KAT3? I bought mine in Oct 2010 and don't know whether the modification in L10/C10 areas was done.

I also tried to tune into a DL and DID get a 1:1 SWR, but when returning to the antenna with the ATU in BYPASS, the SWR was around 8:1. I'll be opening up the K3 to inspect the L10/C10 area on KAT3. That appears to be the problem area. Gary has sent me an email stating they now have different parts for that area. Thanks again. 73, Jamie WB4YDL -----Original Message----- From: Rich - K1HTV [mailto:[email protected]] Sent: Saturday, July 02, 2011 7:00 AM To: 'James C.

I had the problem of a high SWR on 6 Meters when the ATU tried to find a match on my 6M yagi with a known relatively good 1.2:1 SWR. In the BYPASS mode the SWR looked fine. Using the ATU produced a much higher SWR on 50 MHz. If your K3 internal SWR display indicates a good SWR in the BYPASS mode, but the ATU cannot find a good match, there is a fix. I received a BETA firmware update along with suggested parameter changes of some of the hidden MENU settings (need to turn TECH MD on) which addressed the 6M ATU problem. The ATU in my K3 now performs as it should on 6 Meters. Local friend K2PI also had the same problem which was resolved with the BETA firmware update. If your 6M SWR is good in the ATU BYPASS mode, drop Elecraft tech support a note. 73, Rich - K1HTV ______________________________________________________________ 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
