how do we get the old "KW Input" for AM back now?
probably impossible..
You might start with your congresspersin.
We have a couple of hams in congress. Why not email them, especially
hams in their district. One very good argument for going to DC input
is the accuracy of measurement.
Amen. Hey, I'm all for running a full kW DC input again, and more power
to those of y'all that can pull it off. I'm plagued with a bad rash of
neighboritis.
But, still.. for accuracy of measurment, how hard is it to calculate
500w DC input? (uh, gee.. 2500v x 200mA =... Cornbread?) ;-)
Besides, Jim - given that Class C finals are 75% efficient (on average),
what's 75% of 500w?
(just to point you in the right direction, 500w DC input is -half- of
what we -could- run, given that 1500w PEP is 'generically considered' to
be 100% modulation of the product of 75% of a 500w carrier.)
Can I be an instructor now, Don? ;-)
So, we're NOT down 25% of what we -could- run as some lamented.. it's
realistically only 50%.
The saying back in those days was:
"They'll get my kilowatt when they pry my D-104 from my cold dead fingers"
and
"When AM Kilowatts are outlawed, then only outlaws will be running AM
Kilowatts".
(which in some cases isn't that far from the truth ;-))
Think about it, fellas. Asymetrical Audio. Run 500w DC input - have
enough power to modulate the carrier - run 3kW pep
output, and tell the eff cee cee that "my carrier power is 375w! I'm
LEGAL!" No, really - DO IT! Currently, (as Jim aptly
pointed out) who's gonna measure? How could that measurment stand up in
court? Where are they measuring, at the Final,
or at the Antenna?
I think, that if a good, solid, well-built/constructed AM rig was
operated in a gentlemany manner, then that person doesn't draw
that much negative attention to himself and be nice, polite..
Gentlemanly (sorry, I just ain't heard no female AM'ers) and you'll
fly under the radar as long as you maintain. And, you could be running
a kW DC input. (which, btw, is 750w of carrier, and
only 3kW PEP if modulated with a sine-wave to 100% but who talks in
sine-waves?)
