I guess I'm just a Missouri mule. However, I see that most of these
posting praising the KPA500 and the posters don't even have one.
Wouldn't logic say, you can't make a comparison without having the items
you're comparing?
BTW in the 500 vs 1500 watt debate, there is a tool which can pretty

For me, it is pretty convincing (I'm a primarily a DXer) that 1500 watts
suits my operating needs, 500 watts does not. For example two maps run
this morning on 40M shows zero probability of making a contact with VK,
And, the VK amateur using the same tool would never bother to turn on his
rig, because he is limited to 400W. That said, you can often make contacts
when some software predictor said it couldn't happen.

But circumstances are rarely identical.
In any case, if you don't want a KPA500 don't buy one. If you do, then do.
What about that is worth all of argument about it? I had to cancel my order
for one because I needed the funds for another purpose. Once I sell some other
unused stuff I plan
I just fired up my Ham Cap and DX Atlas Applications that measure s/n ratio on a
AZ map.
Choosing VK4 as the other end of a 14MHz circuit, the predicted results at VK4
with a three element Yagi-Uda are as follows:
100w - s/nr 40 dB
500w - s/nr 47 dB
1500w - s/nr 51 dB
In all three cases

That's one of the nicest things about 30 meters: 200 watts maximum, no
matter what. So all these concerns are moot.
I think it would be great if we had at least one MF Ham band with a maximum
power of 10 or 20 watts. (I'd promise not to gripe about the occasional
contest there, Hi)
It's
But not as disappointing as finding that you can't communicate at all with
your QRP rig because there is a contest on with several layers of stations
on every frequency. I like to take my portable QRP rigs seriously as safety
equipment, and the need for that function doesn't go away where there is
In that regard, a lot of folks seem to forget about a little item in Part 97
of the FCC rules:
Sec. 97.313(a) An amateur station must use the minimum transmitter power
necessary to carry out the desired communications.
But then again, when I was a kid I remember my dad scratching his head in
It would even be nicer if US hams actually OBSERVED this rule!
I have even heard a guy telling his QSO partner that he was running a kW!

While I certainly enjoy QRP, it should be be remembered that one of the
greatest problems facing ham radio is the increasingly high noise level
Keep in mind that might not have been a serious statement. I know there has
been at least one occasion where my QSO partner on 30M said something of
that nature in jest. Let's hope the one you heard was also in jest.

Yes, it would be different if everyone honored FCC rule 97.313(a).
We should all then be giving 449 reports on contest day rather then
5NN. In fact, we could make it simpler by saying that 449 was merely
a long string of dots followed by a dash and then a dot.

Guess this has wandered off topic yet again:-)
II have been using the KPA-500 for 3 months I guess and I don't miss the
boat anchor amplifier anymore.
Before ya'all race out and buy 1500W amplifiers, improve your antennas
please because in VK we hear you now, but you have not got 'your ears
