[TenTec] Balanced Tuners

[Ken Klinedinst]

I have used link coupled tuners, built from old QST articles, for 20 
years. About a year ago I was directed to this article authored by 
Richard Measures, AG6K. A true balanced tuner without a balun.

This tuner also appeared in QST Feb 1990 with a variation published in 
QST Apr 2002

My version does not have the small DC motors, belts or gears driving the 
twin rollers, but simply adjusted by two counter dials. Cost was about 
$150.00 which was for the two rollers and one variable capacitor.

I run 600 watts output, key down, 160-10 (excluding the WARC bands, my 
amp does not cover these bands) meters to a 234', center fed with open 
wire, dipole. obtaining a SWR of 1:1 across each band.  The same results 
are obtained on the WARC bands with 100 Watts output key down.

Have any questions please email me
