Hi All,

I'm putting together a TCS-9/TCS-12 station and I read a mention of a
simple mod to allow the TX to use coax-fed antennas. Has anyone got a
copy of this? I'm getting  about 1.5 amps RF into a BC-375 dummy load
but not had much success with an end-fed 66ft inverted L on 80 metres.

Also, the handbook I downloaded has an addendum showing a mod to the
antenna current meter, moving it from a ground lead to the feed to the
antenna terminal, which seems more logical to me. Any thoughts on this?
With an external RF ammeter in the feed to the dummy  load I get the
same reading as the panel-mounted meter.
