Picked up my first one of these over 40 years ago and a couple more have come my way since. Way back then I went through the (toutchy) neutralizing adjustment exercise to reduce the FMing these things exhibit on 75 meters. Also found out that reducing the power output
to 40 watts carrier helped a lot and I have been operating the radio from time to time in the shack and at demonstrations that way ever since. At the time I also made some tests using the radio on 40m which revealed an initial, rapid 3 kHz downward drift on key down along
even worse FMing. Also remember making a quick check at the time on 160M and noting negligible initial key-down drift but didn’t check out anything else.
So, coincident with a renewed interest in160M AM here I recently dug out and installed a TU-5B tuning unit, fired the old Veteran up on 1925 kHz and was very happy to discover (1) negligible initial key-down drift as before (2) NO FMing even when running the rig at it’s
rated 50 watts output and (3) very clean modulation patterns on the scope and excellent audio reports on the air!
