Tell me guys.
Who's idiot enough to build a 5 kilowatt amplifier and use it at the 1,5 kW
level?
Are we kidding ourselves or not?

## Lemme see. New 46 lb plate xfmr for $450.00... or a 120 lb
pole pig for $75.00 New Eimac 8877 for $1300.00 or
a YC-156 for $125 to $300.00 New chinese 8877 for $595.00
or new Chinese YU-148 for $695.00
## well Alex... for the little guy, on the postage stamp sized lot, with his
204BA up 50' and his hb amp.... using surplus 'what ever he can get
his hands on' components.... and getting smoked on the bands by everyone
else. It would be like dangling holy temptation in front of most peoples
noses.
Sorta like having 500 hp... and no cops around. Should I, should I .. just
this
once? No, much better to just get your ass kicked on all bands... and remain
ethical.
## Plan B. You can't afford one of those new fangled pep wattmeters, and opt
to just use a relative power output indicator [ works good] . Just apply full
drive,
and tune the hb amp for max output... just like it sez to do in the dog eared
1967 ARRL
handbook on your beat up 1958 era desk. Since you have no clue as to what
you are
putting out, and have given up trying to interpret your 40 year old 0-3A plate
current meter, you bought for 50 cents at a ham fest, while talking on SSB..you
will never have a guilty consience. I know one fellow, VE7---
who has built several HB amps.. and doesn't even own a wattmeter. He has very
nice amps though. I know a few more.. that didn't include a HV meter.
## Plan C. A SW AM broadcaster starts tuning up, quickly followed by
obnoxious
music.. abt 1/2 khz away from you. You have had the freq for 45 mins. You
decide
to phone up the station manager.. and ask him if he can pse QSY 4 khz. He
tells you
to #&@ ff [ that actually took place] . You are then told by your nice
local radio
inspector, that you are to..'share the band' with other folks... including
the nice SW
broadcaster's. He suggests that perhaps you should instead listen to the SW
broadcast..
and learn about other cultures.. and.. 'world events'.
## Plan D. You have a sked with a group of friends on 75m.. on Friday
night. A contest
is taking place. Qrm from above, then below, then above, then above AND
below. They
start to move in closer. W9-- starts calling 'CQ contest, listening 3564'
right on your freq,
and you ask him nicely if he can pse qsy, as there are 6 other folk on freq.
Apparently,
W9--- can't hear the west coast too well. He finally moves away. You and
all your friends on
freq are all running 700-1500w pep, and trying to have a nice roundtable.
Then, all of a sudden,
58 x stations start screaming at the top of their lungs, on your freq... and
they are all calling some
far off DX station.... who just happens to be working split freq. Apparently
the DX station can't
hear you, or your 6 x friends on freq.
Apparently, the 58 x stations screaming away, are not listening on their TX
freq for some reason.
W9--- breaks in and ask you and your 6 x friends to QSY to a warc band... like
maybe 30m cw,
as you are 'jamming' the Ultra rare dx station, who is on an island.. that only
rises up out of the
water about once every 4 years.
Does that answer your question ?
later... Jim VE7RF
