While indeed national simplex channels would be nice, I'm pretty sure that the 
endeavor is possible.


·         First, the ARRL isn't the frequency coordinator any more. They can't 
declare a national frequency.

·         Each region has its own frequency coordinator and out of the wisdom 
of the coordinators, every now has different band plans.

In other words, the FCC's implementation of regional authorities have moved 
Amateur Radio frequency coordination from being a mess into a much more evolved 
mess.

We are pretty much stuck in the world of 30 year old FM repeaters with no 
desire or incentive to be more efficient players in the spectrum.

Heck, I've got a single, extremely seldom used TV repeater that is complaining 
that their 12 MHz worth of spectrum is getting invaded.

Would be nice to try to pick a frequency that would work
on a wide area basis.

Consulting the NESMC (New England Spectrum Management Council)
band plan:

http://www.nesmc.org/docs/NESMC-Bandplan-Graphic-20071211.pdf

The frequency of 441.000 MHz would not be recommended.
In our area frequencies from 439.025 through 441.250
are listed as either low power restricted or banned.

My personal feeling would be a safer bet would probably
be found in the existing FM simplex segment(s).

[ED - I know the IC91AD and would venture other D-STAR radios can transmit 
clear down to the 430 MHz. range - you are not going to get anything national 
up in the 440 MHz. range, so you might look at 431 MHz., you could probably 
mark off a few 12.5 kHz. channels and have them work in large areas of the 
country. Thinking outside the box may be handy here.]
