This is correct. We use a standard IEC connector in our rear power
module, which also provides RF filtering etc.
We also supply fuses with the power cords.
3AG 12A fuse for 100-125V use. Our 110V cord uses 14 ga wire.
3AG 6A for 200-250V with the PWR-EU2P cable. That cord can use 16 or 18

The KRC2 and KPA500 do a great job of sharing the Auxbus with the K3.
You will need a cable that breaks out a connection going to both

The KPA500 will be far less expensive than the new THP amp.
We'll have more to say on this soon, now that the KPA500 field test is

Way less than that for both the kit and build versions. We haven't set
the final price yet, but the kit version should come in about $1995.
We're in field test right now.
Stay tuned!

I remain interested in knowing if the KPA-500 will handle QSK with the K3 in
CW+ mode at 65 wpm, and if it uses PIN diode switching for QSK.

The KPA500 will do full QSK at over 80 WPM with the K3 in QRQ mode.
Yes, it uses PIN-diode T/R switching.

I'm more interested in how the KPA 500 handles a full blown 48hr CW contest
with full QSK.
What connections are on

I just hope someone from the contesting brotherhood has it and given it a
really good workout!!

To All,
Well I am a bit surprised at some comments. I guess my thoughts on the
'closeness' of the THP caused some angst with some.

My 'shack' (read desk) is a THP Free Zone...:-)

I think Elecraft under-sells the system notion of their products.
Certainly, the K3, P3, KPA500, and KAT500 will work fine as
stand-alone products, but where I suspect they all will really shine
