Well, the basic question that I have is, what do you want to do with the 10 / 11M region? Sounds to me like you want a private dispatch FREQ. Years ago, CB's could be equipped with an audible Tone Burst that opened the Squelch. My Aunt and Uncle in Alaska had that back in 1985, and up there that worked well. How well? From the base of the then Mt McKinley to North Pole, AK. (Look just how far that is on Google, or Bing, Maps.) Then again, on a 30ft river berm, you can see that mountain once you were above the tree tops. They only used AM at the time, and not SSB, but I don't see why it wouldn't work. The problem that I did see with that Tone Blare system was, it wasn't really private, since it would certainly get the attention on anyone on the channel that they were using this. Now, there still exist, but very rare today, legal license-free 11M paging on 27.195MHz. (Yeah, just above CB CH19. I think I've got that right.) That is for data only and I had a chance to work with one such system in college, since the college staff used that on campus, and even beyond. Ya know, with the major migration of licensed LMR (Land Mobile Radio.) going to higher FREQ's like VHF High and UHF, you should be able to snag yourself a VHF Low channel between 29.7 - 49MHz. What you could do there is CTCSS, Voice Scramble, maybe get a repeater FREQ pair, some more possibilities there, but not super cheap. It's like a few hundred dollars for the LMR license. The good news is that there's a surplus of used VHF Low Band radios just being dumped-off, so getting a transceiver for there won't be hard, and most radio shops can still program them. So, that's some so-called legal options to try. If you do Outbanding, it's best to do research to see who would be using those CB Outbander FREQ's, so that you can step on as few toes as possible. The US Gov still claims most of those FREQ's. Good luck!!!
