Re: [Elecraft] KAT500: Fails to tune, and shows 3:1 on good antenna on 18 MHz.

2020-09-14 Thread Dave Cole 

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 come loose. 
Given there are only two connections...  I suspect it will be a simple fix.


73, and thanks,

2020-09-13 Thread Dave Cole 
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...  THANK YOU!  Knowing the tuner is bypassed in Bypass, 
helps...  Next is to put a dummy load on the tuner...

2020-09-13 Thread Ken Winterling 
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.

[Elecraft] KAT500: Fails to tune, and shows 3:1 on good antenna on 18 MHz.

2020-09-13 Thread Dave Cole 

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?
Question:  When turned off is the tuner bypassed?  Which antenna is default?
