[BC] Radiation efficiency

[Paul B. Walker, Jr.]

Dave:

That 50KW on 1550 north of you in Huntsville has a pittful night signal.

It is all a matter of old rules that are outdated.   Its like  having to run
a nightime DA with a resistor in the common point to reduce the  power,
instead of reducing the transmitter power, the rule was written 
when  transmitters
were made to operate in the FCC Power Steps.  The first 2.5  kW's were usually
5 kW. with power dividers until the transformers with taps  were available for
2.5 kW. operation of 5 kW. transmitters.  The 2.5 kW.  was the last official
FCC Power steps put into effect.

As I have said many times if we started over with AM's and gave power  grants
based on ground conductivity and coverage area like FM, a 50 kW. on 540  kHz.
would have the same coverage as the 50 kW. on 1550 kHz.  Also maybe we  could
get rid of so many DA's

The 5 kW. on 550 kHz. would have the same coverage circle at the 5 kw. on
1590 kHz.

Seems only fair????
