A little more background for the FCC (USA) gain restriction for HF amplifiers:
I believe that was a result of wanting to stymie CB use of ham
amplifiers using 5-15w drive. 15-dB for 1500w implies 47w min drive.
The LDMOS being used for 1200w on 2m only require 3-4w drive; that is
26-dB gain!

From the FAQ:
The amplifier’s rugged internal ATU can handle full power with load SWR up to
3:1, while a wider matching range is allowed at lower power levels, including up
to 10:1 in standby mode.

Hi Fred,
Thanks very much for the reply.
I tried the first exercise. With VFO NOR enabled, the frequency remains
constant. With VFO OFS enabled, the frequency decreases by 60 KHz which, I
guess, is my CW pitch.
When I am operating, and i switch from SSB to CW, I have to retune which I find
I must have missed something to generate the exchanges on internal and external
tuners and antennas with more than 3:1 SWR.
I am guessing that the matching range at 1500 watts for the KPA1500 tuner is
limited? Is it similar the KAT500 which is limited to 3:1 at 1000 watts? Has

Ralph,
Yes, the A to B mods are worthwhile. I have done many of them.
Download the K2 A to B instructions and look at the first page to see
the entire list of associated upgrades.
The only 2 mods that are not listed there are the K2 Keying Waveshape
Mod and the Extremely High Signal Handling
Wayne, Eric, and everyone else who had/has a hand in making this happen:
Well done! Simply superb effort to overcome multiple and significant
obstacles on many fronts.
Please, do place me on the list of folks keenly interested in knowing
when one might place an order/pre-order. :-)

Excellent point I look forward to deploying more/better copper! :-)

An excellent point missed by many of the desktop tuner and high feedline
SWR advocates who insist on using coax fed antennas. Typically, they
blame their failures on cheap coax.

Ease up for a minute Look at it my way. I KNOW I am gonna need an
external tuner with massive capability to do the same thing I am doing
now only one tuner on the commercial market will tune my 80m loop

I didn't WANT an onboard tuner... I consider the pric
As I understand the way things work, they will not get approval for the
device, if it is easily modifiable to defeat the current limit, so I
would expect them to play down any modifiability even if it can't be
classed as easy.

Revision B fixed a lot of things.
With your experience, I would do the A:B upgrades and all the other
mods. I'm not sure the DSP board is available any more from Elecraft,
DSP's CPU part not made any more is what I'm remembering.
I did them one at a time, spread out. Not a one or two night projec
Mike,
You get an "as calculated" price from separate software would be my
guess. So that they can pass on their cost to you to keep your price as
low and fair as possible.
You're new here I suspect, so I understand the cynicism but it it
definitely not warranted under these circumstances.
Hi Fred,
$5995, complete with internal ATU and external, lightweight switching power
supply. See:
http://www.elecraft.com/KPA1500/KPA1500.htm
I might point out that only Elecraft offers a legal-limit amp with a
palindromic price tag :)
