Nope. No QRO and no HRO or DRO or PLO.

I've used commercial wideband high-power VHF amplifiers for
testing in professional work. Smaller than shown in the
photo.


What does it matter what you've used professionally that you didn't
build, Len?

But the 3cx10,000a7? Hardly amateurish. Probably more in the domain
of professionals.


Sounds rather ILLEGAL to me if "used on 80m" as claimed by
the seller.


What would be illegal about using such an amp on 80m?

Not something that HRO or even Henry Radio would feature in
catalogs ("call or write for details and prices"). Pro stuff,
probably intended for something rather different than pure
communications.


From the looks of the exhaust vent in the E-bay photo, I'd say
that it should be about a 10-gallon RF output thing, quite out
of the amateur legal limits.


That doesn't mean that it is run above the legal amateur power limits.
It only means that it could be.

Besides, it doesn't have enough
knobbies on it to "qualify" for an amateur radio transmitter
on "the bands" (HF).


A linear amplifier isn't a transmitter, Len. It amplifies the output of
a tranmitter or tranceiver. :-) :-)

Sweetums you clueless old fart, check out the ACOM 2000A "amateur" HF
2kW+ amp, not a "knobbie" in sight.

Get a life.

Heh. Yessss . . Reminds me of the time there was a flap in this NG
about that Eimac bottle or one of it's close cousins being used to run
56kW in a Chevvy Suburban truck during CB "shootouts". I tossed the
56kW "mobile" station topic into the thread as post #150 and the thread
went on to 899 posts before it finally died. The thread was "CW =
Engineer ?" circa 1 Sept 98. It's still available.

Back when folk like Carroll, Hare, Tennehill and McCollum populated
this NG and the average IQ hereabouts was 30 points higher than it is
these days.

Sweetums was there too of course tossing out all sorts of his usual
inane blather even back then . . like it wasn't possible to run 56kW in
a Suburban because the coax and antenna would get toasted by all those
amperes worth of RF.

giggle!

Nothing illegal, so long as it's used within the rules. I have a couple of
different amplifiers which could easily be driven beyond 1500W out, but are
perfectly legal so long as the power output rule is observed.

That's the crux of the whole thing, isn't it?

"Legality." :-)

...and just who checks your "legal status" in operating?

Oh, my, there's LOTS of different "technical" regulations
in Part 97, Title 47 C.F.R., aren't there?

The same can be said of Citizens Band Radio Service. It was
"okay" once and legal to have a linear amplifier connected to
a CB transmitter provided one did not exceed the regulatory
limits found in Part 95, Title 47 C.F.R. Uh huh... :-)

A company called General Radiotelephone once operated in
Burbank, CA, on Magnolia Blvd a few blocks from Hollywood
Way. They had - once - a cramped, busy assembly line
operation going on the second floor of one building on
the north side of Magnolia Blvd. Their major product was
a CB transceiver which was ready to increase its power
output from 5 to 35 Watts (by removing a jumper) "if and
when the FCC allows a power output change." It SOLD in
quantity with that "feature." The company planned to
expand in the near future and had put up most of a triangle
tower for their CB antenna...tower still visible half-
erected on the roof today. Of course the FCC never did
increase CB power output. The offshore import CB rigs
arrived to undercut their prices and they went Chapter
something and quit the business. [no, I didn't have one
of those General Radiotelephone rigs, but they were in
my vicinity and I was up on their second floor factory]

Now and for some years there has been a legal no-no on
even being able to PURCHASE a linear amplifier in a certain
frequency range...which could be used for a CB radio...or a
10m amateur radio. Can you connect the dots and see a trend
for the future there?

If someone has a 10 KW linear that covers all of "the bands"
(HF) then it is tempting both faith and human nature to say
that a legally-licensed (certificated, tested, got their
legal license in the nave of the Church of St.Hiram) amateur
will ALWAYS OBEY THE RULES. The temptation is GREAT...just
sitting there, ready to go, beside the operating position
in the "shack."

Of course YOU will always be scrupulously honest. [was
there any doubt?] Are all the other legal amateurs just
as scrupulously honest?

Be honest now...

A single dot does not constitute a trend.

And the "legal no-no" (§97.315, §97.317) does not apply to homebrewed
amplifiers, which the item in question appears to be. Amateur-to-amateur sales
are also exempt.

Sunuvagun!

Didn't the FCC change that in the last year or two? Since it didn't
successfully keep the amplifiers off the CB band anyway, I believe they
dropped that restriction.

Since I have to head off to work shortly, I don't have time to look it up
now but I do remember reading something on that.
