If I recall the KT-36 has a simple 4:1 current balun and the elements are
quite complicated with a lot of capacitors shorting bars and spacers. I
would suspect something is wrong with one of more of the complicated element
parts or possibly a broken driven element phasing line.

Hi Scott,

You are not the only one with the problem you mention.

Checking my KT-36 today, I have resonance at
14.068  1.8 SWR  95 ohms R  0 ohms X
20.937  1.0 SWR  52 ohms R  0 ohms X
27.497  1.1 SWR  43 ohms R  1 ohm X
(NO, I am not trying for the 11 m band!)

As far as I can recall, when installed about 12 years ago, it was in 
the middle of the band, but obviously is low now, especially on 15 and 
10 meters.

I am fairly sure there is no problem with water.  The only thing I can 
think of is the balun.

If you discover anything, please pass it along!

Thanks.

73,

Ken, W8EK
