Sorry for asking an off-topic question but I just know somebody reading this
can shoot back a quick answer. I am building up an old Mosley Classic-33
tribander wihtout the manual. Can somebody tell me if the Driven Element is
closer to the Director or the Reflector? That was the one thing that didn't
get labeled on disassembly. Thanks.

Perhaps I am a bit late for the discussion on Italian kilowwats, but I =
just couldn't resist it...
Few years ago I travelled to Italy on busisness and paid a visit to a =
ham whom I knew for ages from a band. I was kind od surprised to find =
him in a workshop where, among other ham stuff, there was something =
called HF PA, size of a decent refridgerator, very carefully =
manufactured and good looking. I understood it was predicted to deliver =
20 kW out (you read it right) and Henry 2K was used as a driver. Bird 43 =
with 25 kW (right again) probe was used as a wattmeter. Dummy load was =
water-cooled. You actually had to tap the water from the pipelines, =
hi... If I remember well, the tube was YU134, size larger than my =
head...
There was another small amplifier with 3CX6000, some 8 kW out...
Your mouth are watering? Come on, admit it... never thought of using one =
of these babies in a contest, ha?
Yes, I have seen these two amplifiers by my own eyes and purpose for =
writing this is not to point out Italian hams as the only superpower =
users. You can find them in almost every country in the world. Many of =
those high scores are results of extreme powers combined with good =
antennas and operator skills. In my country I know for at least two =
amplifiers with 3CX3000 (two, ha ha ha...). Some S5 guys proudly talked =
about their big amps. There are also many others to whome I hav not =
spoken , but who could say the same.
Thing is, it is hard to compete in any WW contest due to differences in =
regulation among countries. In USA it is 1500 W out, in UK 400W, in =
Italy 300W etc. If classification would be on country basis, perhaps =
people would stick to the rules ( I do not believe this...). Then, what =
about dxing... Plus, it is much easier to build a strong linear than =
plant a high tower and long boom yagis...=20
It is very difficult to trace the use of excessive power, strong signal =
is not the only relevant pointer. That makes it much easier to use.
Henry 5K? Henry 8K???? Whom were they dedicated to? Power savers? Tube =
lovers?
Yeah, forgot to tell you that heating transformer for YU134 was some =
heavy thing and wires size of my thumb (180A, right?).
Italy is a beautiful country of nice people, nature, art and of course =
kilowats. What I mean is - do not press it too hard on Italy, you can =
find extra power next door. Trick is how many of No 1 contesters would =
let you in their bedrooms? Sorry, shacks... I bet there you could find =
lot of active tuners, coaxial cables with positive losses and dipoles =
with 10dBi gain...
Be better, power is not all.
