[Amps] AL-1200 T/R problem

[Karel]

Hi Ken,
just of the top of my head and I am sure there may be many other reasons,

I would first look at the relay and tried to clean the contacts. There are 
contact cleaning files, but perhaps contact cleaner spray might be tried 
first.
73 and good luck,
Karel, VA3KO
