How does it perform into a known good dummy load? If you don't have one get
one ..about $39 from MFJ

Hi,
I seem to have a problem with my kenwood 450s. I can transmit fine on 80
and 40 meters but when I go to 20 nothing plus there is what sounds like
an echo when I try to transmit. The antenna tuner says the SWR is Ok.
I use a G5RV antenna and thought that this may be the problem. I have just
installed an "ENDFEDZ" 20m end fed dipole, the results are the same. I can
receive OK and there is no difference on the transmit side when I bypass
the tuner and connect either antenna directly to the radio. Any help /
suggestions would be gratefully appreciated.

Many thanks
Ian
