[Elecraft] K144XV or XV144 transverter?

[John Lemay]

David

The secret with these RA Mitsubishi modules is getting the heat away, and
they're not very efficient at all. The earlier M series were a little better
(I notice that's what shows on Elecraft's web site pictures but no doubt
they have had to upgrade when stocks ran out).

Looks like the internal transverter runs discrete components ? Can't quite
see enough in the pictures to be sure.

Johnny -
The Mitsubishi RA30H1317M module used in the XV144 is supposedly rated 
at 30W at 135-175MHz.  Having said that my XV144 seems to trip out if I 
run it more than about 5W on FM.
