Default vhf extra channels

What you are refering to are sometimes called the \"Expansion Channels\". I have been trying for years now to find out just what these channels actually are, where they are located (what frequencys) and how they are designated (what channel numbers). I have had no luck at all, beyond that some guys say they have and use them, and some guys that have heard of them but haven't seen them in action. Apparently there are some radios that can be set up to use them by simply opening up the back and flipping a switch or something like that, but I can assure you the M-127 is not one of them. Once again, this comes from what I have been told by people, not by any experience with the things. It seems to me that I've been told that certain models by Uniden and possibly Standard make it easy to get to these channels (but no one who has told me they use them has ever come back and told me how the channels are designated, so I have my doubts). So, that's one thing, they apparently exist but I have no good information on them.

The second thing is this. About a year ago the FCC published a proposed rule that would have allowed for doubling the number of channels we now have and use (this would have been USA channels only). They proposed to accomplish this by cutting the channel separation in half. Our channels are currently seperated by 0.050 MHz and they were going to cut that down to 0.025. So where we now have this:

USA 1 156.050
USA 2 156.100

We would come to have:

USA 1 156.050
USA New 156.075
USA 2 156.100
USA New2 156.125

And so on. For whatever reasons that never happened, and I have no idea why.

Now to ramble on for a bit, actually I just feel like ranting and raving for a bit this morning so you may choose to ignore what follows. The normal process for changing our frequencys would have worked like this: The radio companys would have lobbied long and hard for some new bobble for our radios. The Lobbbiest would have been wineing and dineing the cream of the crop, our Congress and the Political Appointees who run the Agencys. In this case the Agency in question would the the FCC, which has as its Administrator a fellow named Powell, who happens to be the son of Colin Powell. The Congressment would lean heavily on the agency to do as the lobbiest wanted, but that would have nothing at all do to with the favors bestowed on them by the lobbiests (don't believe that? Just ask them). The FCC would then have checked and found that our channels exist where they do and our power outputs are what they are and our licensing requirements are as they are by international treaty, but that they don't apply to our own USA channels so the those could be changed. That there are serious complaints about congestion on the frequencys. That there is no money to enforce current rules for radio use that would easily take care of the congestion problem. That there is an industry that would gladly support a new feature they could sell on radios. So the FCC would have asked a very few selected lobbiests to draft a rule they would like to see. The lobbiests would do that in a heartbeat, in fact they would probably reach into a brief case and take one out. The FCC would then publish that, or something very very similar, in the Federal Register, for all the world to see as a proposed rule. The publication would go on for some time, 30 days minimum I think it is, and a time would be set for public comment. The public would be invited to submit their concerns about any part of the rule, from the actual wording to its effects. The FCC would then have to respond to each comment. The responses would then be published, also in the Federal Register, and if all went well at some point down the road a Final Rule would be published, also in the Federal Register. Final Rules have the full force and effect of law, and so they would become the law of the land and the radio manufacturers would have the ability to submit their plans for new radios to the FCC for 'type approval'. This means that the FCC doesn't really ever look at a radio, just at the schematics (often just basic block forms at that), and that they approve any model that is on the market. Once Type Approval was granted the manufacturers could then start advertising these new generation radios as the most important safety featrure ever created by mankind and convincing you and me that if we didn't have one, and have one dam quick, that our lives and the lives of our loved ones would be in great peril. Pretty neat system, wouldn't you say? Here's the really neat part, sometimes during the phase where someone has to check and see if it is even possible to adopt the rule it is found that the Congress had ratified some multi-party treaty or another back 50 years ago. Sometimes they find that the treaty governed how we establish our channels so as to conform with the rest of the world and that the proposed rule would be in conflict with that treaty. When that happens the poor slob that had to do the checking is branded by the lobbiests, the Congress, and the Political Appointees as a Bureaucrat who is getting in the way of progress. What's really funny is that its not that the poor slob had any choice in comming back and saying that the rule couldn't be put in place because of the treaty that the very folks who are now in his face put in place.

I have seen many charter boats with two vhf's and they will operate one on U.S. channels and the other on international frequencies but you are right that some captains have private channels that they use and I have not been able to crack them either.
Mumblerone please solve the mystery

Thom,
I bought a Standard Horizon Eclipse Plus waaaaay back in 1988 for a new boat. This radio would do tricks and go to frequencies unknown to mankind.
Actually you could program any freq. from 140 +- mhz. up to 160 mhz. by taking the cover off and switching a slide switch then program the freq. that you wanted by the front panel buttons.......switch the switch back to the original position and that was all.
I even had the local police freq. programmed.

It was all printed in the back of the owner's manual.

This radio was sold with the boat and to this day is still operating.
I'm sure if you search long enough on the web that there is a site that will show you how to modify any radio.....some by just clipping a diode.

I ran a charter boat out of manasquan nj from 1987 till 1999 and we all spoke on the exp channels.The entire charter and head boat fleet on the nj coast uses them. If you have a standard vhf it is easy to do , open up the radio and flip the exp. dip switch, then program the channels you want. Icoms 120 vhf was easy later models were more tricky. Thom the 127 can do it but it is a software load from icom. Problem is that speaking on these channels is unlawfull so icom and standard are leary to tell you how to do it. You need your dealer to do it for you. I still use the exp channels now on my private boat. I dont talk much but use it for intell only, nice to have here in nj were it gets used alot. the marine freq starts at 00 and goes to 280 if I remember both simplex and duplex.

sorry... thought it was still available by looking at my profile.

I guess that feature went away.

Anyway thanks MUMBLER!

I too would be interested in the document being discussed. Being a HAM and a member of the USCG Aux, it could be useful (and maybe even legal!)

Thanx much!

Oh, and anyone know anything about any Icom IC-M502 mods?

It would be very handy if these things could be made to cover our AUXNET frequencies.

I fish out of Barnegat and would love the extra channel #'s, so that i could set them on a Standard VHF. I too would only listen, not talk, but my catch might benefit from the "info".

Mumblerone-

You got my curiosity aroused (common to "cat" owners...). If it's not a hassle, I'd appreciate it if you could put me on the list as well.
Thanks!

Expansion channels are available on many radios. Some you simply flip a switch inside the radio but most of the newer radios require a program change. Charter captains and others use them in lieu of a telephone. Gets rid of the endless chatter they don't want to hear and allows them to talk about things with out everyone hearing them. I think some or maybe all of the expansion channels are actually assigned for other use but I have rarely heard anyone on any of them.
