Thanks to Mike and Bill for buying my 2M80 amps (assembled or partial 
kit).  I built twelve amps so far and most were to be driven by KX3's 
with 2M module.  I set nearly all amps to be driven by 1.5-2.0w so 
the KX3-2M would not have to run full power.  The 80w RF module that 
is used is not in production so now limited quantities available 
(from RFParts).  I have identified a replacement power module which 
should run 60-70w.

But there are quite few surplus 2m linear amps available.  Mirage, TE 
Systems, and RFConcepts.  I have a RFC 2-23 linear which runs 2w/30w 
and RFC 3-17 linear which runs 40w/170w.  I have three 2m sources: an 
old FT736R (30w), DEMI 28-144 HP (50w) and the KX3-2M which not up to 
stuff running only 1.5w.  I use either the RFC 2-23 or a surplus MOT 
amp that runs 1w/60w (FM) with my KX3-2M.

I am not taking orders for a couple months as I am working on some of 
my own projects while summer wx is still here:
6m 1kW amp and possibly building a new 18x26 foot ham shack which 
will require running all new cables to my four towers and dish.  Take 
a look at the amps here: http://www.kl7uw.com/kits.htm

Ed, KL7UW, built me a nice 80w 2m amp for less than $400.

Does  anyone use a KX3 + internal 2m transverter with an external amplifier?
I am  looking for any recommendations. I have looked at RM Italy LA-144
and  Mirage B-34-G. My intention is to use it with both FM and SSB. Does
anyone  have experience with one of these amplifiers?
