Re: KPA500 question

Well, if you want a kilowatt station the Icom IC-7600 and PW-1 offer the
same functionality with a built-in antenna matching circuit.

Curiously, I am getting about 400 watts out of the PW-1 driving it directly
with the KX3 at 12 watts out (no ALC).

Re: KPA500 Question

In reply to this post by W2RMS

I don¹t know what the design rationale was, but I do know why I went that
way after looking at KW and 1.5 KW amps from several other manufacturers.
Pretty simple - I can run the KPA500 and the K3 from existing 117 vac
power in my home. A KW would require either a dedicated 220 line or an
increase in my fire insurance coverage. The on-the-air signal gain from
500 to 1000 isn¹t very much . . . cheaper to put another few DB into the
antenna system. Having decided that 500 was the right size, choosing
Elecraft wasn¹t even in doubt due to the integration of the equipment,
among other things.

Re: KPA500 Question

I found that the K-Line set-up (K3, P3, KAT500, and KPA500) fit very nicely
into my RV-turned-shack. You can see my operating position in the top
picture on my QRZ.com page (click to enlarge). After replacement of a
board "sandwich" early in its life, my KPA has functioned perfectly, and
usually gets me through the pileups I want to work. I usually run it at
about 400w, and find many other KPA users do about the same.

Re: KPA500 question

In reply to this post by Charlie T, K3ICH

I just added the KPA500 and the KAT500 last month - first amp I've ever had but so cannot compare but love it!
Issue for me was ability to run on 120 volts. Great fun to assemble both and as mentioned nice compact grouping / size for my space constraints.

Re: KPA500 question

Same here re adding the KPA500/KAT500. I did have
an Ameriton AL-811H, and still do -- but have not
fired it up since 2002. Worked fine, but not easy
to use since it needed re-tuned with significant
QSY. So mainly I did fine with my K2/100 and it
was great until replaced by the "greater" K3!

The Elecraft system is pretty much like having a
500 W. K3/P3. Once set up no need to touch the PA
or ATU. Plus it the KAT500 handles switching among
three antennas. I have four but #4 is a 30 m
dipole and I mostly use that with lower power rigs
(K2, K1 or KX3).

The main shack re-work I needed was to replace
RG-8X in-shack coax runs with RG-213. The AL-811H
was only used with my beam and mostly on 20 SSB,
and had dedicated cables to the antenna port. My
desk and shelf set up worked fine with the amp and
atu -- and my shack looks much neater (there was a
Kenwood TS-570DG where the KPA500 is now).

Re: KPA500 question

Ok, fine. You guys convinced me.
I'm getting KPA500/KAT500 over at Dayton next week.
Elecraft guys: here i come!

P3/SVGA monitor resolution question

Hi everyone!
I just got this new Dell LCD monitor specifically for the P3/SVGA.
Its a 19.1 inch, 16:9 monitor.
However, its maximum resolution seems to be 1366x768 at 60Hz.
So the only res i can use on the P3 is 1280x1024.
Any way to include the monitor's res in the SVGA firmware, so it can display natively?
Not that it's unusable, but would be nice to have...
I tried higher res numbers in the SVGA but the monitor refused them.
Its a Dell E1914H.
I guess that's what i get for getting a $65 monitor...
