In New Youirk -- We Say "Forget A Bout It." Why talk to a concrete wall.

If you try to correct all the false stuff on the radio groups or anywhere
else -- you would have to hire a full time team of a dozen people (at
least).


Caveat Lector -- Let the reader beware and leave it go at that.

Regarding the power calculation -- see URL:
http://www.ameritron.com/ameritron/p...rodid=ALS-500M

This is a 400 watt CW (500W PEP) mobile amplifier and it "requires 14 VDC
at 80 amperes peak current for PA transistors and separate line for 14 - 16
VDC at 4 amperes for control and bias circuits.That ought to help. Tis a
matter of efficiency

You do the math

That should take you to the proper thread. If not, look for the post from
"mad dog" posted at 9:35 am.

I kid you not, these are his words:

quote
Keep the P=IxE formula in mind when choosing a mobile amplifier.
Power = Current x Voltage
or Current = Power / Voltage
P=Power or Wattage
I =Current draw
E=Energy or Voltage
Example: Tommy truck driver wants to install a 1200 watt spurious
emissions generator on his Kenworth with a 12VDC electrical
system. We just learned that Current draw is calculated by dividing
the Voltage into the Wattage so if the 1200 watt cataract producer has
a Input Voltage of 12 Volts then the Current draw will
be...............................
One Hundred Amps (100). Yes folks you read that right,
that is more current draw than most alternators can produce.So please
be realistic when adding accessories to your already marginal electrical
system or you may find yourself playing the "Prince of Darkness"
on a very wet and rainy night.

He is wrongfully assuming that RF power output is equal to saying
12volts*100amps.
Assuming the rated output power is 1200 watts.
As I have dealt with radios for years, I know for a fact that this is only
an idiot's explanation.
He's big bad mister trucker trying to show off how smart he is.

I have tried to explailn it to him and he will not believe anything other
than what he has written.
So if one of you could come in to the thread and explain how damn wrong he
is, I would appreciate it.

thanks for the time.
