I am looking for a 10 meter mobile radio that will also work on the CB band. Now before anyone starts on how its illegal to modify for CB and the 4 watt limit stuff. I currently have a CB in my truck but the only thing I use it for is lisitening to the truckers tell where the cops are sitting. I think I have talked on it maybe twice in the 6 years its been in there. I would like to replace it with a 10 meter mobile and it would be nice if I could find one that will also work on CB I do not care if I can transmit on CB as long as I can receive thats all I need. Having both in the truck is not an option because I am going to use the CB antenna for the 10 meter radio and do not want another antenna (I allready have 4) or have room for another radio. If anyone knows of one or has any suggestions I would apreciate it. I do have a scanner in the truck that receives CB but I have that connected to a 18" 1/4 wave so that really doesn't work unless I am right next to the person I am listening to. I have looked online and I see mods to change from 10 meters to 11 meters but that is not what I want. I want a 10 meter radio but would like to have the extended RX into 11 meters.

Many multiband HF transceivers have "shortwave, continuous" frequency coverage for receiving.

This is the way to go.  Forget about a "10 meter rig," and think about an "all band" rig (won't cost any more) that includes a continuous coverage shortwave receiving capability, as they almost all do.

All my HF transceivers (160-10m) can "receive" on the CB frequencies just fine.  They won't transmit there, but they can receive there just great.

An inexpensive and simple way to go is to find a Radio Shack 10 meter radio and install a switch box, like a Dosy brand, that will allow you to use one antenna for both your CB radio and the 10 meter rig on receive. When you want to transmit, just switch to one radio or the other. That way, you are in compliance with the rules and do not lose the ability to transmit on CB for an emergency or road information. For best overall performance, tune the antenna to 27.5. You will find the CB antennas very broadbanded. In the case of a 9 foot whip, all you have to do is take the spring off. This set up has worked well for me!  

A more expensive solution is to find a multiband HF rig that will receive CB and hook up an autotuner at the end of your CB antenna (hopefully, you are using a 9 foot whip for best performance). If you have trunk space near the antenna, this would also be an easy solution and provide more space inside for passengers.

What is the average range people are getting out of 10 meter mobiles running mobile to mobile? I'm not talking skip here just basic operating under decent conditions. The dependable range so to speak.

My experience has been the one watt per mile rule when communicating from mobile to mobile, unless one of you is on a hill or a bridge. The range is greatly expanded when talking mobile to base.

As an added suggestion on my previous post; when using   multiple radios on a switch box hooked to one antenna, always turn off the other radio when transmitting to prevent receiver saturation and or damage.

I think I am just going to scrap the CB and simply replace it with a 10 meter. The little I do use it isn't worth the trouble of trying to have both.
Another question about the range how does 10 meters compare with 2 meters for range? about the same? I am talking no repeaters or skip just average mobile to mobile comunication.

Thanks for the replys I apreciate it!!!

I bought one of the AM antenna to Cb boxes at a truck stop and used the vehicle AM radio antenna for the CB (used mostly for receive, not very efficient for transmit).  Then used a s/s whip cut for 10m for the HTX-100 radio.  As for range on ten meters, my experience in while I lived along the coastal GA swamps was 10-20 miles ground wave.  I used a 10m 3 element beam and the R/S HTX-100.  I havn't done too much on 10m since moving back to MN, aside from the fact that 10m is pretty quiet now.

I found a magnum 257 its one of the new models with the blue display. Seems like it would work great for what I would like it to do. Anyone used this radio or have any thoughts on it?

That's legal to use on ten meters; illegal to use on 11 meters, as it is not certificated for Part 95 (CB) use; in fact, it's on the FCC list of "banned radios."

However I have a feeling you'll use it, anyway...

This is the way I understand the "schizophrenic" laws regarding the FCC banned radios: It is illegal for a dealer to sell these non-certified "CB's" as the way the FCC categorized them, but it is completely legal for a ham of appropriate class to buy and use them on 10-meters (and 12-meters as some of these radios are capable)!    

We can also, of course, "home brew" our own transceivers if we have the talent, patience, and time to build one from scratch. We legally can even convert a true CB radio, somehow, to operated on 10 or 12-meters.  No "Type Acceptance" needed here either.

I also understand that it is completely legal to "open" any transceiver (HF, 10 meters, 2-meters, etc.) to transmit on non-ham bands or frequencies as long as the operator never, ever, transmits on these non-ham bands or frequencies during normal conditions.  The only exception would be a literal, true, life or death circumstance without any other options (no CB, cell phone, etc.).  In a situation like this, any radio, band, frequency or mode of transmission would be perfectly legal for hams and non-hams alike.  It has been done without any consequence.

For the "emergency" reason, I know several hams that will "open" or "unlock" all their rigs.  Virtually all of the ham rigs around can be opened by simple modifications (moving jumpers, cutting diodes, etc.)

I may be partially wrong but I really don't think so.

Try this:
Get a 10M radio. I bet there are good deals on used ones now. Get a radio shack CB antenna. Trim it to get good SWR for 10M.  Get a portable cheap CB radio.
Have them both connected to the same antenna using a duplexer. I did this. I listen to CB when I need traffic info and I use the mag mount CB antenna trimmed to 10M.

That was for the OP. I had an HR2510 for just that reason. It was nice to be able to talk to Argentina or Portugal on 10, then twist the knob to find out why the interstate is at a crawl. I never had anything to say on cb. It eventually died.

So I replaced it with a radio shack 10-meter ssb only radio. It was useless in traffic, so I had to mount two antennas, and a 2x4 under the dash to bolt it and a CB. Very silly and impracital.

Thus brought me to the IC-706 solution. Horrendous receive on 27mhz AM, and I never found an HF antenna solution that I liked.

A small cheap radio that will do 10 and listen on 11 is what the OP was asking about- and it sounds like the 257 fits.

P.S.: Most HF radios are easily modded for general coverage transmit just like the "10 Meter Export" radios- so lets keep things in perspective.

The answer is to buy an Alinco 135 DX 10, 12 meter mobile, it is computer programmable and NOT field or by changing the electronics so you could program it for receive ONLY on what ever frequency you desire between 24,510 and 29,700. That should make those so afraid some how a mike might get keyed on a Ham rig on 27, megs, if this should happen the world would surely end.

I wonder how the law suit of discrimination is going with the FCC's failure to ban ALL the radios made by the big 3 or 4 manufacturers not being held to the same standard that ANY radio modifiable to use on 11 meters can no longer be imported into the USA. The equal treatment under the law is still a part of our Constitution and would have to apply to all HF radios or it becomes discrimination and unconstitutional, because that is the only standard used for the ban.

It is an FCC administrative rule and not as law passed by Congress, likely the ban will be either be extended to ALL hf Ham radios, HF marine radios and HF land Mobile radios or be removed from all. Court cases take years and years to work their way to being dismissed or a settlement made, in the end it might cost millions to settle. I understand all the criminal cases HAVE BEEN dismissed already, that speaks very loadly to how the Courts may be viewing this as a matter of equal protection under the law and not as an emotional ham hate CB issue.

Or nothing changes and the FCC rule stands. I happen to have one of the 10-12 radios and dislike possibly losing the use of my radio, there again equal application of the law has to apply equally to all.
