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.

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). Bob McCormick W1QA (also NESMC VP and WMA director) [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.] [Non-text portions of this message have been removed]
