The other Idea I was toying with was a repeater, which is kind of going over the legal line, but this will be out in the middle of a big farm. My hand held can't reach back to the base at the house but the one in the truck can. So my idea was to transmit on the lower 40 from the hand held to the truck and have it repeat it on one of the regular so I could get the signal to the house. I would use the dual watch feature of the hand held to listen in on the regular 40 channel. I'm far enough out in the woods on the farm that I'm not going to be stepping on anyones toes and the game warden doesn't even come around (have cousins who hunt out of season, but they hunt for food not sport and are careful to not over hunt so the game wardens overlook them since its been that way for generations) so I don't think the fcc will be bothering to come by and check. I'll disable it for any driving so I'm not stepping on any toes or causing trouble.

With the "lower" channels, as folks say, here's where you will increasingly get into trouble. I just got back from a meeting of communications officials. How many of you have heard of Automatic Link Establishment (ALE)? NO, NO, not something you can drink! 
It is where the radio "polls" thousands of frequencies in fractions of seconds and establishes 'links" according to the Maximum Usable Frequency (MUF) and what is the best frequency to use. All the radios in the agency, both transmitters and receivers, are sampling frequencies at the same time. They call each other and the user has no idea which HF frequency he is on; he just picks up the mike and talks and the receiving station gets the call and the traffic is passed. If the agency has.....say 30 frequencies ranging from 2 MHZ to 26.800, the radios are constantly polling each other and establishing links with each other at unfathomable rates! Now, let's say the best "link" happens to be on 26 MHZ, BUT there are unauthorized people filching there! Rest assured, it WILL get noticed and the military authorities will go after those who operate there thinking there is a "freeband" for them to use at will. If you know what Pactor or RTTY sounds like, if you are on one of those unauthorized frequencies and get a "RTTY" burst lasting about 7-8 seconds, this is a radio polling others in the network. You, OTH, won't even know that the network has "noticed" you. Radio also keeps a log of the results of its polling, and that's how the military folks know you were there---if they don't outright hear you. But you WILL interfere with them, and THAT ain't a good idea--even if you never hear a word!! It doesn't mean that frequency isn't being used; it's just in a different way from the way we think of using a CB radio!
So, in today's changing technology environment, don't automatically assume that "that channel ain't being used!" The uses to which military and commercial entities put their commo resources are not dependent on what we as civilians think. They have objectives, communications plans, and needs that *we* don't understand. And as these needs change, these agencies, particularly military, are relying more and more on what we think is "obsolete" when, in fact, "old" technology is being used, just in new and better ways. ALE has been around since WWII, but in today's security environment, it has found new advocates. You wouldn't GUESS who actually had a hand in inventing ALE! It was a Hollywood actress named Hedy Lamarr!!! She was drop-dead, stunningly gorgeous, but also smart, too. Twenty six and 27 MHZ do, still play a part in this frequency-hopping technique. Hope you enjoyed this bit of trivia.

i believe icom has a radio that uses this type of communications
it is sold to be used in the land down under only
i think it is the 7400 series

Why not use MURS?

I just wanted the person to be aware is allSwitch Kit said:
A kill Joy is a kill joy , it can be looked at in many ways ,shapes or forms. My personal business is at hand ,yours and others are none of mine unless they directly effect my personal well being......this is when I have the choice to turn the cheek or find the need to make it apart of my personal business. Usually when it comes to CB radio , turning the cheek is a automatic occurance. A kill joy is in the eye's of the beholders , not so much in the eye's of the kill joy's , it's usually very natural for "them". No offence meant here to you Pluto ,leave it not to me to lable you or anybody else ,I personally think "they" do a good enough job of it on "there" own. The scratch in the record will continue to repeat itself and the song has remained the same for decades past. Peace
It's all good, Switch......I understand the term kill joy, I was just a messenger trying to not get shot.

Motorola has these, too. They are primarily put to military uses. Come to think of it, ALE is the HF equivilent of "trunking"!
And, BTW, the subject of "freebanding" and its effects on commercial and military HF communications was discussed in this conference! I'm afraid some of the attendees had less than complimentary things to say about those that do it-and it was coming from at least one military officer who is much aware of the practice!
As the use of ALE becomes more and more prevalent, and it clashes with "freebanders", it sounds (from the gist of what was said last weekend), it might get less and less "free"! . Other subjects covered were linking with state and local authorities to achieve that new buzzword---"interoperability". But that is mostly UHF and VHF stuff!73

I am not trying to stir things up but... it sounds like you are reporting:
The Military's new state of the art system is so fragile that a freebander could interrupt crucial communication?
If *I* were in charge of critical Military communication, *I* would recognize the FACT that 11 meter freebanding IS a world wide phenomenon and not localized to the US. I would acknowledge the FACT that the FCC is under staffed and funded to effectively police the band and that they have no authority outside of the US. I would then set out to design a system that was robust enough to get the job done, after all that is what Hedy Lamarr's goal was... to design a system that could not be jammed. That system may use 26MHz, but would not be adversely affected by someone using the commonly available 'Export' radio.
I am not condemning or condoning freebanding, just making observations.

And there's a lot in this thread I am not telling, too! For reasons that should be obvious to all, there is more to it than our discussion on a web forum! Things ARE changing, and it may soon be that a "freeband" won't exist anymore without consequences to those to encroach there!
