[BC] The Main trouble with radio..

[Tom]

Ah, but, you see - if a DA is NEEDED, it's not licensable!  Under my 
plan, the ONLY reason to install a DA is to achieve offset in the 
transmitter site vs the city of license.  Very similar to why some 
FMs use a (slightly) DA antenna.  There would be NO critical 
patterns, and the rules would specify that to drop another station 
in, the engineering studies MUST presume ALL stations ND, whether 
they are or not (again, borrowing from the FM allocation 
standards).  Most remaining arrays would be maybe two or three towers 
- no more of these ridiculous 6, 8, 12, 37 tower arrays that must be 
maintained +/- 0.0003 degrees!
(Although I could see a three or four tower _fixed_ array - think 
Giant Vertically-Polarized Yagi... ;-) - since only one tower would 
be driven, no need to have a phasor or an antenna monitoring system - 
just the base current for the driven tower.)

Oh, and another thing - let's fix Part 15 while we're at it.  Up the 
power limit 30 dB (100W) into a 1/8 wave (maximum) radiator on AM - 
and while we're at it, up the field strength allowed in the FM band 
from 250 uV/M @ 3M to 2500 uV/M @ 3M.

And allow any modulation scheme you like - analog, digital, mono, 
C-QUAM... as long as it's not true SSB.  Even Kahn AMS (the carrier 
is still there as it exits the antenna, right?)
