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.

Hi Web,
I also use all of the XVs in my shack and they do not have a heat problem.
The only restriction we place on them is for continuous duty FM use, where
we recommend that they run at 5W. I believe this is where some customers
felt they were hot when they didn't follow this recommendation and tried to
run FM at 20W for long transmissions. For SSB and CW use I've used them in
contests with zero heat issues. Also, for your requirement where they are
run at 10W or less they will have even more margin. 1W for the 432 will be
cool regardless of what your duty cycle is. :-) I don't see a problem.
The XVs are linear transverters and can have their input driving power
range set by their internal jumpers and power range potentiometer. You can
easily set them up so that they only put out 1W or 10W max for a given
amount of drive. (This assumes you are driving them with low level inputs
in the -20 dBm to +10 dBm ranges and can control your max drive power.)
Please feel free to email me if you have any further questions. Another
good person to talk to is Mike, K7MDL, [EMAIL PROTECTED] ,who has all of
our XVs in his mobile VHF/UHF contesting rover set up. He has a web page
describing this set up at:

Subject: [Elecraft] Transverter inquiry
Question 1: I'm thinking about buying all the transverter kits,
and remember that some folks said something about a heat
problem. Has Elecraft made any modifications to make them
run cooler?
Question 2: All my amps require 10 watts input- 20~25
watts would probably damage them. My 432 amp only
wants one watt input, I think. Is it possible to turn the
RF out down when building the transverters so that it would
be impossible to exceed 10 watts (or one watt, in the case
of the 432 transverter)?
Thanks, -Web in Myrtle Beach, SC
