Hi
Thanks to those who replied to my mail about the KP500 SWR tolerance. My
friend is also grateful and sends you thanks and best regards.
The best of all to the list, and a Happy National Day !

Come on, putting a 500 W PA into such a small enclosure is already an
incredible achievement in itself (congrats, Elecrafters!) and a matching ATU
cannot be built with miniature, surface-mounted type components, can it?
Let's stay realistic. If Elecraft is really going to offer the ATU in a

Hi,
That's a brilliant blog entry and it really resonates with me as I am in the
exact same situation. If I can hear them I can *usually* work them but not
always and that 5x boost probably would put me over the edge. My main worry
isn't the 2K dollars but potential interference with my neighbors

I gotta say I’m with Bill-N6FB on this one.
I am interested in the KPA500 but disappointed
that it did not come with an on-board tuner or at
the same time as the KAT500… so now I am going to
wait to see what evolves with the KAT500 later on
before I take the plunge. I could buy an LDG
AT-600
I thought Eric stated that they hoped the tuner would be out around the
fall time frame. When I last asked it was in design.

An on-board tuner is impossible with the KPA500 and power supply in
the totally minimalist K3 case. The KPA500 is almost impossibly small
for amp + supply. This extreme compactness of the amplifier will be
the big selling point for many buyers. Maybe the KAT500 will be in a
P3 case.

Based on that, the price per watt for SPE is say $3.9 per watt but with

The PW-1 antenna tuner is only 3:1 wide so it is not a full function antenna
tuner. Indeed, I use that in concert with a Palstar AT1KM antenna tuner for my
horizontal delta loop (all bands). I don't include the AT1KM when I am
operating with the Hexbeam antenna as that is 1.5:1 or better on
The KAT500 is being designed to match 10:1 at 500 W.

Hi Johnny,
Yes, me too. Also I got confused with the KAT-500 which I also really need
so I can use the remote version attached to my trailer and just use a single
feedline to the Motorhome.
I can use the Yagi tri-bander, a 40M vertical and a double extended Zepp for
40/80M etc.

Hi Bob,
Yes, you may be right but K3 is a top of line radio with price tag over
$2,000.
A couple of stainless steel screws are not necessary damaging its profit margin
but just make it more perfect.

Hello Wayne,
The beauty of Elecraft gears is that you have the free choices to select your
preferred options to suit yourself. I am always interested in knowing the
total
bill of KPA500 + KAT500 as a whole in due course.
Naturally, I would expect a much stronger metal enclosure + screws +
Hello Jack,
Elecraft's practice is to offer you different options to choose such as
additional ATU, PSU, remote control, band data decoder etc etc. As a result,
the initial price tag could be very attractive.
The merit of this arrangement is that you have the absolute freedom to choose
