I've always planned to extend my QRP K2 with a KPA100/KAT100 in
a separate EC2 - this would let me pack up my barefoot K2 for
/p operation without much nuisance, and still run QRO when desired.
I figure that's at least 12-18 months away, given the other projects
I have lined up. If Eric and Wayne
Does this option alow better cooling? I was a little surprised to hear comments
that make it sound like working RTTY might really overheat the unit.
I am building a K2/100 now and will stay the course, but I would be interested
in hearing more. A 100w amp and tuner in a box might indeed be a nice
I am leaning that way as well, since I will want the option of running
100 watts available. It would be nice if, in a future update to the
firmware, we could leave the cables connected and have the K2 detect the
state of the KPA100/KAT100 combination automatically.

Thanks to Don, W3FPR, for clearly delineating what is required to put the
KPA-100 in a separate enclosure. I'm certainly leaning in that direction, and
somehow the Elecraft Web site doesn't spell out these details very well.
BTW, the reason I'm considering the 100 watt amplifier is because day
A more accurate subject, should have been:

Fred,
It sounds like you are a good candidate for a KPA100 in an EC2 enclosure.
If you also add the KAT100-2, the KPA100 plugs into the KAT100 board.
Without the KAT100, you have to make a hole in the EC2 rear panel for a coax
connector (KPA100 input) and make up a cable from the base K2 AUX I/O D
My original inquiry concerned my options, with a
new K2 build - for adding some more power later down
the pike. I've always liked separate items; xcvr,
tuner, metering, and amplifiers. In some way - the
way I upgrade frequently - its easier with all the
pieces, for me to swap/sell out a single it
Tom,
I don't think you will be thrown off the list - this is not a QRP reflector,
and with questions about the (hopefully forthcoming soon) KPA800 and
KPA1500, it is definitely not all QRP oriented - there are folks of both the
QRP and QRO persuasions using Elecraft gear.
Your thoughts are consis
I'll probably get thrown off of the Elecraft list for what I am about to
say...8-)
Don't get me wrong...I love QRPmost of my contest participation is at 5W.
I can work the world with 5W. And on 10M during a solar peak I can break
pileups with 5W.
But my experience is that 100W with a d
Oh, and I forgot one thing. No FAN! Just a nice HUGE heatsink. No matter how
quiet the fan, I just hate fan noise.
The things holding me back from buying a KPA100/KAT100 are only 100 watts and
the fan. Another 6 db and no moving air noise would tip the scale for me.

Yes, yes, yes
>From what I understand, the KPA800 has two 400 watt power modules combined to
produce 800 watts. So, a KPA400 with just one of the power modules, a
built-in lower power antenna tuner, no combiner, a smaller power supply,
solid state T/R switching, and without some fancy bells
Yup... That's the reason I stopped building them.

I've been watching prices of K2's on eBay for a few months and it appears
you may be correct. It's tough because there are sometimes auctions where
the seller sets a ridiculously low "buy it now" price

I don't understand the reluctance to add the KPA100 but at the same time
suggesting a smaller, non-Elecraft amp to drive the new KPA800/1500. You can
build your KPA100 in a separate case if that's the problem.
