Brief Comment

I agree with the ARRL petition for regulation by bandwidth, and support it, 
with one major exception.
The League claims that their plan does not favor one mode over another. Not 
true. It favors AM-DSB
operators. It would allow for 9 KHz AM modulation, in bands which otherwise 
are limited to 3.5 KHz.
These include the lower HF bands, which are quite crowded at times. The 
solution is simply to
restrict AM-DSB to above 28.5 MHz. (10 meters & above) Amateurs and the 
league have been
upset in the past over wide-SSB modulation, meant to improve audio quality. 
AM is no different from
this. It is an old modulation that adds nothing to advancing the 
technological art, and should be
confined to bands where there is ample spectrum available.
