Fwd: [Elecraft] Transverter inquiry

[Mike Lewis]

I will add that I just added the XV432 to my stack, and I adjusted it for a 
maximum of 1mw output to suit an external amplifier by choosing the right 
combination of input attentuation in the transverter.   Additionally with 
the K2 as an IF rig, and some other rigs, you can set the per band power 
output to further limit drive power.  There is a huge range of adjustment in 
the transverer attenuator.   I run most of my xverters at 2-10watts to suit 
my amplifiers.
