Hi ken, Added the dummy, no problems, so it is the antenna... Also, given it is a 6BTV with the 18 meter add on, and all other bands work, it is not the feedline... This makes it simple to fix! It is either a break with the laws of physics as we understand them today-- or a connection has c

That helps triage the issue... Something in my antenna must have gone wonky... I am using a 6BTV, with the 18 Meter add on kit, so the same feedpoint is used for all bands, and they are fine... I was worried it was the tuner. I'll go check the antenna out tonight, and in the morning as well

When you have issues like this the best test is to use a known good dummy load. That removes the antenna system from the equation. See what happens on 18mHz when transmitting into the summy load. Ken WA2LBI On Sun, Sep 13, 2020 at 6:58 PM Dick Dievendorff wrote: > When unpowered the KAT500

When unpowered the KAT500 is bypassed, ANT1. When the ATU is in mode BYP, yes, it’s bypassed. 73 de Dick, K6KR > On Sep 13, 2020, at 15:52, Dave Cole wrote: > > Hello, > My KAT500 which worked yesterday, now shows a 3:1 on 18 MHz., only. Antenna > is a single feedline to a 6BTV, and an anal

Hello, My KAT500 which worked yesterday, now shows a 3:1 on 18 MHz., only. Antenna is a single feedline to a 6BTV, and an analyzer says all is good at low power. At 100 watts, all seems good. All other bands seem OK at high power. Question: When in bypass, is the entire tuner bypassed? Ques
