Amazing... What's old is new again. Wasn't that 45MHz - 50MHz FREQ range where they've tried FM broadcasting 1st, before deciding on 88MHz - 108MHz, due to "E" and intense F2 propagations? BTW, when I worked for a natural gas company, they heavily relied on 48MHz two-way 100W rigs to talk in the middle of no where, where 800MHz cell phones could not even touch. Especially in North Central Pennsyl-tucky. (Not Pennsylvania. If you've been there, then y'all know what I mean.) Is the Federal Corporate Coddlers giving them the boot? I understand that Mexico is trying DRM in the 11M Broadcast Band. Plenty of unused spectrum there, even if F2 and "E" is more prevalent. I understand that DRM works better than that bandwidth hoggin' Ibiquity HD Radio.
