Titolo: I sell Big Amplifier & Antennas

I sell the following amplifiers HF, all under perfect conditions.
3 Ampli Collins 208U10, autotuning 2-30 Mhz, 10 Kw continues, with exciter
Redifon/Harris.
3 Ampli Siemens, autotuning 1.5-30 -Mhz, 10 Kw continues, Siemens.
2 Ampli Collins 205J3 new, modified by the Collins 45 Kw pep, autotuning
2-30
Mhz.
1 Ampli Harrises 84V, 13 Kw cw.
4 Antennas Log periodic 2-30 Mhz 10-50 kw.
I have cable, connectrors, end more.
They take an interest you write me.

They are a little bit over the legal limit???

Leslie,
In the US, the FCC imposes no limit on the power your
amateur radio transmitter may be capable of, only on the
amount you actually generate.  It is not illegal for me to
own a 10KW transmitter.  I can use it on the air, so long
as I do not use it above the legal limit.

Those are the amps used in ARRL DX contest with the exchange 59-300 
:.)

 "Only dead fish go with the flow"
So some people like to run big, who cares? it's all in good fun. 
(sounds like really neat equipment :)))

   Naw- They're just designed for "CONSERVATIVE" operation...

Yeah, I have the electrician I just hired downstairs wiring in the new 80 
amp 220 line ;)
The way I figure it, I'll only need to drive it with about 6 watts from 
my FT-900 for legal limit... and if the lights in the neighborhood start 
dimming..... hey, dont look here!

Several years ago someone PAID for an ad in the Yellow Sheet which said
that I was selling one of those 10kw Collins amplifiers.  I got a call
from Italy, a call from someone representing an Italian, and a call from
Japan.  
I had never even heard of the amplifier until I started getting these
international phone calls!
Draw your own conclusions.

Great for the 75 meter gang (hihihi). Just perfect for getting through
the QRM, unless the other guy saw the same ad!

HAMS care. It is not legal and it ruins the bands for the rest of us.

Well said! Listen to power struggle at night on the 75 mtr. fone band! I
hear guys 200-300 miles apart saying "hey your 40 over, oh yeah, your 60
over here! My daddy's amp. is bigger then your daddy's. ;-)

 YOU MEAN TO TELL ME THAT AMATEUR OPERATORS RUN EXCESSIVE AMOUNTS OF POWER
AND BREAK THE LAW ???  EVEN AFTER THEY HAVE TAKEN AN EXAM THAT CLARIFIES THE
LEGAL POWER LIMITS AND THEY ARE FULLY AWARE OF THIS ??    DOESN'T THE
HANDBOOK AND THE TEST STATE THAT ONLY THE AMOUNT OF POWER NEEDED TO COMPLETE
THE CONTACT IS TO BE USED AND NOTHING MORE, UP TO THE LEGAL OUTPUT LIMIT
????  now how can they criticize cber's for doing the same thing when many
of them don't even know what the legal power limits are or that linears are
illegal for them to operate on cb freqs???  sounds like the old double
standard hard at work again.  Sean aka Bigfoot

You didn't do the math, did you?  There are quite a few appliances in a
house that draw about 10 KW. At 220 volts, it is less than 50 amps.

Well Bill,
That calculation may may be close for your electric range, but I have
yet
to see an amplifier that is 100% efficient.

Yeah, but...  In neighborhoods where houses were built with electric heat,
and gas came through later, like mine, many houses have excess electric service
capacity.  Mine has a 400 amp service, and no longer uses the 2*60A @ 240V
that fed the 20kW electric furnace; nor does it use the power that fed the
electric hot water heater.  But...I'll bet most 10kW output amplifiers have
3-phase power input, and that would be a serious problem in residential
areas.
(Me??  I'd much rather use simple, low power equipment and get
satisfaction from operating skill and effective but simple antennas.)

Let's face it - for a ham setup , nothing would be finer than
that three tube 3cx800 amp being sold by usa manufactor.

Well Rob,
Lets do a little scenario. Take the 13kW continuous offering for example. 
Now say it only runs at 50% efficiency. We are now up to 26Kw. Throw in
another 4kW to cover other losses and we have a grand total of 30kW.
At my house, with a 200 amp main, each leg runs 121V-122V no load. With
every thing in the house that uses electricity turned on and and a few
extra 500W floodlamps plugged into spare plugs, 1000W metal halide flood,
air compressor and a 2hp deep well jet. Oh, I ran the hair dryer also. The
voltage drops to a minimum of 116V while drawing 137A. My electric company
was kind enough to use 2/0 copper for the connection to their secondary.
That gives me 232V phase to phase. 30,000W/232V = 129.3A  This still
leaves 70.7A to run the rest of the house on. An amount sufficient to run
the rest of the house under normal conditions. 
Electricity wise, I don't see any problem. Actually, it may turn out to be
the least of all problems. Of course you may put a kink in the theory of
divirsity that the electric company uses in figuring distribution
transformer kVA, but that is their problem. They'll just have to use a
larger distribution transformer if you contest a lot.

areas.
In Europe, three-phase is readly available. Power is distributed locally
by a three-phase 415V Y-system, and individual houses get a 230V AC feed
from one of the phase conductors and neutral. Neighboring houses are
connected to different phases to roughly balance the neutral current.
Large buildings and light industrial users get all four conductors. 
In countries such as Sweden which have a history of large electric
heating demand, even individual houses have three-phase supplies.

Why waste time to determine if the average house will run an amp this
large?  It is NOT legal to run in the US for any ham. Unless you crank
it way down ... 1500 w output = legal max.
