Well this is probably moot now that the story has been told (Re: K5GA's
rundown of the antennas...holy aluminum, Batman!!!) but I was going to say
that W5WMU obviously, to me, has more going than high power because I am
*always* able to work him/them in the 10-meter contest on scatter. A lot
of the other close-by big guns in 4/5 land are pretty loud on scatter but
most of them can't copy my puny signal no matter how long I scream at them.
W5WMU and a few others...N4AR, more I can't recall...always can hear me.
On the other hand, those "300 watt" Italians who are always 4 or 5 S-units
above the rest and still can't copy me, I'm not so sure about...
For the record W5WMU was 50db over S9 on my meter on 20 CW last Saturday,
and I don't ever recall a non-local pushing my needle so far to the right.
Even WRNO Worldwide on 7355 with 100KW only runs about that strength.
Wow.

Every month on the back of the DX Mag there is an ad that says
"Creative Electronics Has Your Amplifier" (and unless we receive
a ransom of.... oh no, never mind).
Anyway, one of the amps illustrated is advertised as "3-30 MHz,
10 KW". They have been running these ads for as long as I have
subscribed to this mag. Now, it's called a Commercial amp, and
they illustrate some others that would be no use in CQWW (50 KW
at 450 Mz...) but presumably hams buy their products. And of
course they may well have amps that run less than a KW, too.
I think we are all in awe of the mega stations with their superb
antenna systems, and I bet most of them run close to legal power.
Whatever the antenna system, I think most of us lose any respect
we had if we know for sure that 5-10 KW is fed into the things.
I don't know first-hand of anyone who does, so I will shut up.

A thousand kudos to Bill, K3ANS and his wife Hope for letting me use his
station this weekend.
Participation this year was apparently way up (or maybe it was just
Bill's antennas). 20 was great, 80 was pretty decent, and 40 SSB was a pain
in the ass as usual. Sure was hard to catch W1AW and the VE hq stations.
This is a great summer contest. If you didn't play, you missed some fun!

HI ALL,
High power... I gess one thing is being missed here.
What is high power? How much is inuff to be in the
class of high power? Anything above the license limit?
Well, hr in Russia it is 200w dc input... How can a
Russin compete against 1kw US amateur fairly? And so
on, and so on...
I consider power factor in a real simple way. As long
as one is capable to run a station with "gas" ( doesn't
matter if its a 100kw one) without interference
to others on band, to be read - loud but clean signal,
it is OK with me. It is 100kw guy's problem if he is
known as a "big alligator" not ours as long as he does not
QRM others.
As long as fairness of competition... Is it fair when a
3 over 3 on 40m guy is against a dipole guy? Is it fair
when P40 is against VE5, and so on...
Contesting is a mix of human and technical factors.
I strongly believe that human factor preveals the technical
one, so talking about 4 - 10dB difference in signal strength,
due to higher power,
while other factors such as antennas, locations etc produce
much bigger advantages/disadvantages is just another whining
session here on reflector.
Is it because a 6 dB increase in signal strength due to higher
power costs a lot more $$$ per dB, provided you already run a KW,
then going fm a dipole to
a 3 el., and once you have a 3 el. and yet you want extra 6 dB
you have an option, either put up a huge collinear stacked array,
or increase yor power which costwise is about the same and not
affordable to too many of us...
BTW I adore guys that have built high power amps (10 and more KW)
and were able to keep their signal clean, not bothering anybody,
and at the same time having not earned reputation of the "BIG
ALLIGATOR" ( I hate the latter).
AS long as W5WMU. For many years it is a "big gun", for many
years W5WMU is about the only zone 4 multiplier that hears and
is heard on 80m here. I want to congratulate the owner of W5WMU
on that! BTW W5WMU's 20m sig in IARU was loud, but not exceptionally
loud.
P.S. I had never run a station in contest with less than 1.5 kw output.

If anybody wants to draw their own conclusions about the use (or implied use)
of big amplifiers (not only in contesting, but everyday operation), just pick
up a copy of the Yellow Sheets sometime.
I am constantly amazed at how many really BIG amps are for sale each month by
completely unknown (to me) callsigns. Of course most of the ads read something
like this:
Amplifier 1500+++ watts output, etc.
I bet there are 10-15 amps a month in there that are advertised in that manner.
This of course is not meant to imply that everyone who buys (or owns) one of
these monsters runs illegal power. But it is interesting how many are out
there.
By the way, the description of the WMU QTH as being "swampy" reminded me of
another local station here close to me NM2L who lives in a swamp. When I
was at 7Z1AB during 1990, Greg was always 7-10 dB louder than all of the other
local guys running the same or better antennas. Swamps seem to be great
signal boosters.
Now if he could just kill all those damn mosquitos, I would visit him more
often!!

Ok, for the past couple of day I been reading the messages about this topic.
My question is What would you consider BIG POWER?
I don't see no problem that a station would run 10KW or 100w, a course
if is legal, he can go for it, and if is not and he goes for it that is a
matter of him and the agency of the goverment encharge of regulating Ham
Radio.
Now, maybe you have 10KW but how is the reception!, they maybe can hear
you but you don't hear anything.
My point of view, in the majoroty of the messages express
that "Is It Fair", well is a fair a 4 ellemnt quad station vs a single
dipole?
Just let be...

So who are the gassers? Will the list appear in Heidi Fleiss' book? (we

Subject: Thanks RE: IARU - first contest ever ...
Thanks to all who personally e-mailed me about my first contest experience
this past weekend. All your comments are greatly appreciated AND
encouraging. Certainly the one thing I have learned is that contesting is
year round -- some of the smaller "regional" contest actually seem like
they would be quite challenging (Columbian Independence Day Contest ?!?!?).
My only regret is waiting until last January to get my ticket. What was I
thinking back at Rose-Hulman when I turned down all those offers to get
started in amateur radio. ;^)
Well, guys, thanks again! I have never before met a group of people who
you have no clue who they are, yet they treat you as if you've been friends
for years. Amateur radio is great fun! [Is that proper grammatical
construction? I think my mom would shoot me if she saw that. 8-D ]

Message-ID: <199407141408.KAA11646@noc.tor.hookup.net>
Not withstanding the fact that these amplifiers are available and out there
somewhere no one seems to have touched on what would be/is required to
operate one of these things.
Its a given that you can't have one in a residential area feeding your tribander
so that eliminates the majority.
So now we're talking about the multi tower multi antenna country folk.
Now the fun part starts. What do I use for coax..7/8 Heliax won't stand the
gaff.
What do I use for coax relays? What do I use for the rotation loops?
I know some of you can answer these questions and you also know that the
solutions are not cheap. In fact they very expensive.
To run some of the implied powers is certainly not a plug and play situation.
I only have 3 towers and a couple of stacks but I'd hate to think of the cost
and logistics to convert to a nitro station.
As John N0UN sayes you buy more with aluminum at the "right" height than
you do with a bigger amplifier.
My example goes back afew years and I was operating long path from UA3.
Most of the locals back home were on 20 (tribanders at 70ft and 1kw) and
running about S5 to S7. When John VE3EJ came on (5el mono at 150ft ) he
was 15 to 20db over and he was only running 100 watts (the Alpha hadn't
warmed up yet). But when the band went short path John was just another
VE calling. In fact there were other locals who had him beat. The 150ft antenna
was killing him and his bottom 5el was out of service.
A classic example to me of the right and wrong height for a given path.
I could give many more examples but you get the idea.
Long boomed yagis at the right height get my vote each and every time.

Good lord! And I thought W3LPL was impressive. But let me ask the
obvious question that you don't address directly. with all this effort
to get the last Db out, can you state categorically that only legal power
is run? After all, at some point, it's probably easier to run 8x legal
than it is to find the 9db any other way.
