That should read the antenna connections on the back of the KAT500 -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-KPA500-VSWR-on-6m-tp7610474p7610485.html Sent from the Elecraft mailing list archive at Nabble.com. __

I noticed that my vswr on the K3 did not match what the KPA500 showed in the standby mode. what I found was that I had the 6 mtr ant connected to the ant 3 jack. I changed it to ant 1 and the vswr was in more in agrement with the K3. It seems that the distance from the input to ant 3 connector is e

When the KPA500 was keyed up, the K3 VSWR went from 1.2:1 to 1.0:1. Because the input circuit offered a j0 match, I concluded that the problem had to be associated with the amplifiers output. In bypass mode, the bypass relay connected the input directly to the output. I was confident that the Ele

Jack, I am sorry to hear that you had problems with the twisted pair wire. Normally twisted pair makes a very effective and self shielding transmission line, even at 6 meters. The characteristic impedance does depend on the diameter of the conductors and the thickness of the insulation separat

Does anyone have this problem? I was having problems on the low end of 6 meters. VSWR was all over the place! The K3 would always measure a 1.2 :1, the KPA500 measured 1.5 to one and the KAT500 wouldn't match my 6 meter beam. I agree that there was a problem with my Hygain 66DX6 but even on my
