Default Trio AT-180 ATU

The is a wierd one,thought ATU,s never went duff! However this one of mine has seriously high swr even if going into a 50 Ohm dummy load.Get more out of the tx without the ATU,which was ok a year or so back.Tried cleaning switches etc and checked for dry joints but to no avail.Any thoughts ?Thanks David GM8JET

Thank you for that,they have been made up professionally and work fine (swr ok) in to the dummy load.Put the the dummy load in where aerial goes and back to 10 to 1 swr! Same as long 66foot wire and earth.
