Nice site, Jim. Thanks for the link. Very nice
instructions on the amp, too.

Another option for a tad more power is to "roll you own". W6PQL had an article
in the May 2013 issue of QST for building an 80 watt out all mode 2 meter amp:

He has a ton of other home brew projects on his web site. I built that amp this
past spring and it works great. I made my own cabinet, but bought the board
from him. The parts were obtained through various online retailers. It works
great - I've used mine, driven by 5 watts from my K3, on CW, SSB, and FM.
Just a thought.....

One could always buy a Mitsubishi brick and put it in a case. RF parts or eBay:
eBay item number:121444258503
$45 for a 30W out module fully assembled. Or $58 for 60W out. 50mW drive. Add
an LPF, bypass switching and you are done.
Normally set up for FM, they can be run linear by adjusting the gate voltage.

Subject: Re: [Elecraft] KX3 Questions
Jim -- Definitely agree on the need for an amp with KX3 2-meter. I have
posted, more than once, my Elecraft wish list item of a nice 2-meter amp. It
just seems like something that would be easy for them to throw together.
Otherwise, there are a few 2-meter amps I have been looking at but so far I
have not needed one (mostly since my home brew 2-meter yagi is not anywhere
near done yet).

But, if you are wanting to do weak signal work with CW, SSB, etc. then the 2M
option is a very good cost item and worth the small increment of $.
Yes, IF you can find a good amp that drives with the 3W or so that the 2M
transverter produces. There was an '80s vintage Mirage 2W In, 150W out brick
that did that, and I have one (but there's no way I'd sell it). :)
