K2 with (Another Brand of) Amplifier?

It is probably not good manners to mention another brand name on the
Elecraft list, but is anyone using the Tokyo Hy-Power HL-45B with the K2?
It auto couples to the FT-817, but I understand that a connection (assume a
bandswitching connection) can be built for it to other rigs. If anyone has
done this, how hard was it to do/how did you do it? My K2 is QRP, but I
don't need 100 watts. I might desire from time to time, however, to
"muscle up" to 20 or 25 watts to chase something. Tnx for bandwidth es
73/72.

Fwd: K2 with (Another Brand of) Amplifier?

This is a thoughtful reply, and I appreciate it. The money differences are
not a worry. However, I was thinking of (but didn't include in my message)
the K2 100-watt amplifier in an enclosure since I don't want to build it on
board the K2. I was looking at $450 for the FL-45B and $480 for the
Elecraft amp and enclosure. I guess there could be some other parts I
would need? Very happy camper either way, but the FL-45B sits on its own
without need of an enclosure.

I think I picked up on an answer to the bandswitching question. Does the
FL-45B have band buttons on the front panel? I can't find an image big
enough to be sure.

Just some additional words sold by weight and not by volume. Tnx, Steve et
al.

Well you don't have to use 100W. I would think that the K2100w amp would be
the way to go and much cheaper as well. Looks like bandswitching is a
simple matter of pushing a button in lieu of auto switching.

Re: Fwd: K2 with (Another Brand of) Amplifier?

As has been mentioned recently, adding the KPA-100 in a separate EC-2
case is a very effective solution. The close integration between the K2
and the amp is a joy to behold. I use this configuration, but with
the KAT-100 automatic tuner as well. You need the KIO2 in the K2 itself
if you don't already have it installed. This is a bit of a hit, cost
wise, but I think you would be happier in the long run. There are
numerous articles available with text and pictures that detail the
process, and it is actually even easier to do that those articles would
indicate. If you decide to go this way, I can offer some additional
tips that will help during the build process.

Re: Fwd: K2 with (Another Brand of) Amplifier?

I have the separate EC2 KPA100. This allows me to keep my battery
configuration in my K2 and use the 100 watt amp to drive QRO in the shack.
The integration between the K2 and its various add-on components is very
slick, down to being able to set and read the output of the KPA100 from the
K2 power knob. The QSK of the combination is crisp, and the K2 switches to
driver mode when it senses a powered up KPA100 on the proprietary Elecraft
bus. This setup has been so useful, that I might still have it when I've
traded my K3 in on a K4 :>)
