Unbelievable!

I don't usually say much on these lists. But I have just finished building
my KPA500, and I have to say that in my almost 50 years of hamming, this is
the most incredible piece of equipment I have ever had. Now, I am not
related to Elecraft in any way. They don't even know who I am. But I am so
impressed with the quality of components and the engineering and thought
that went in to this little package that I may sell my other amp (name
starts with the first letter of the Greek alphabet) and buy another. My
other amp is so noisy, the fan runs so loud and the "QSK" relays
clickity-clack" when sending CW. The KPA500 is as silent as can be,
generates over 600 watts without any noise at all. The only time I can hear
the fan is when I shut down the amplifier, it turns on to bleed the high
voltage to make it safe if you want to poke inside. No other piece of
equipment I have ever had does that. It follows the K3 without blinking. And
the software gives you all the measurements, including temperature, that you
would ever want to know. And the satisfaction of breaking a pile up with
half the power I usually run, puts the fun back in operating.

And all you guys can say is you don't like the color of the buttons.
Unbelievable!

Unbelievable!"

I'm with you Fred. I wish Elecraft made cars. They would read our minds, last for 20 years and get 300 mpg!

Re: Unbelievable!

Well, it did not get 300 mpg, but the 1989 Mazda turbo MX6 that I
recently gave to my daughter lasted me for 22 years and had over 250,000
miles on it - it only got 24 MPG in normal driving, and 30 mpg on a long
trip. Loved the handling and responsiveness of that car, and found it
hard to give up because I knew I could not replace those qualities.
Even after 22 years, the upholstery was still in good condition.

So it is with Elecraft gear - there may be other "bells and whistles"
introduced by other manufacturers, but the performance of Elecraft gear
is here to stay. Yes, I drink the Kool-Aid, but there is benefit to
that too. I have Field Test K2 SN 00020, and it will have to be pried
from my "cold dead hands" - that is my "pride and joy" - and it is fully
upgraded to the latest level. That capability is now expected for any
Elecraft product - other manufacturers want you to buy a new transceiver
to get the upgrades.

Actually, I would think that Elecraft would just skip the old antiquated car technology and build a nice
transporter like in Star Trek.

Like all things too good to be true, this posting about the KPA500 is a
bit unbelievable. Like cars, YMMV.

My experience with the KPA500 is much different. I suspect Jack only
operates SSB.

On CW expect the fan to come on after a few transmissions in under 30
seconds. Levels 1, 2 and sometimes 3 are often heard when doing some
rag chewing at 500 W. The temperature stays below 70C as it should.
RTTY is about the same with contest type operation. Expect the fan to
operate as designed for these modes.

It is not an absolutely quiet fan. I doubt Muffin type fans can be more
quiet that what is used on the KPA500. One would have to go to a
centrifugal fan like used on some of the really silent big amps to have
it "pin drop" quiet.

< K3BHX: "And all you guys can say is you don't like the color of the buttons.
Unbelievable!">

I can't speak for everyone Fred, but if this comment was a response to MY post, you certainly missed my point. I was not critical of the KPA500. I don't even have mine yet. But, the listed features alone blow me away and I look forward to getting mine. I hope you're not including me in your "all you guys can say...." post because that just isn't true in my case. I simply posted my personal reason for wanting the buttons on the KPA500 to match the other gear within my "K-Line".

I love all things Elecraft and shout praises for the E-Team from the highest rooftop. I'm sure I'll feel the same when I get my KPA500.

That said, the button color is a personal preference involving *esthetics*, not performance. It's not a big deal. And, it's an issue that someone else already found a quick and inexpensive fix for, should one want to change them.

OK, I'll button this up now. ;o)

Re: Unbelievable!

Hi Brian

My experience with the KPA500 exactly mirrors yours. After some fairly long
overs, my fan begins to sound a bit like a vacuum cleaner although nowhere
near as loud as my former linear, a Yaesu FL7000. I do not find any cause
for complaint. It is simply a fact of life.

I am also bewildered by people who say they never hear the fan in their K3.
Mine comes on almost from the start and I can always hear it, even with my
headphones on.

Re: Unbelievable!

Hi Barry,
I suspect your RX noise level there is very low. When I put headphones on
first thing I hear is 59 + noise on most of the bands. Sure enough I am
never bothered by fan noise of my K3.
All of the above is said to tell how much I envy you :)

Re: Unbelievable!

In reply to this post by Barry Simpson

On KPA500 fan...

My fan will only kick on after a somewhat sustained signal. This occurs at about the
one minute mark for SSB and maybe about the same for CW but my CW transmissions
do not always cause the fan to switch on. I monitor the temperature too and it seems
to run cool.

Note that the efficiency of heat removal has a lot to do with not just external
air temperature but also the density of the air which of course is affected by
humidity too. And of course, the availability of surrounding air currents that
help to cool without the fan. My KPA500 is in a fairly open room where the
average air temperature is about 68 degrees.
