• To anyone looking to acquire commercial radio programming software:

    Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.

    If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.

    To obtain Motorola software see the Sticky in the Motorola forum.

    The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.

    For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).

    This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

Commercial Gear for CB?

Well, FRS also requires a fixed antenna, is limited to 0.5 watt, and is FM which would make such a bizarre combination impractical and probably expensive...

I read through the FCC rules and have a question about remote control.

§95.419 (CB Rule 19) May I operate my CB station transmitter by remote control?

(a) You may not operate a CB station transmitter by radio remote control.
(b) You may operate a CB transmitter by wireline remote control if you obtain specific approval in writing from the FCC. To obtain FCC approval, you must show why you need to operate your station by wireline remote control. If you receive FCC approval, you must keep the approval as part of your station records. See CB Rule 27, §95.427.
(c) Remote control means operation of a CB transmitter from any place other than the location of the CB transmitter. Direct mechanical control or direct electrical control by wire from some point on the same premises, craft or vehicle as the CB transmitter is not considered remote control.
Would a homebrew cross band repeater be considered "direct electrical control by wire" since it would be wired to the other radio?


I also saw that CTCSS is allowed. You'd probably need an external encoder to not violate the internal modification rule.
§95.412 (CB Rule 12) What communications may be transmitted?

(b) You may use your CB station to transmit a tone signal only when the signal is used to make contact or to continue communications. (Examples of circuits using these signals are tone operated squelch and selective calling circuits.) If the signal is an audible tone, it must last no longer than 15 seconds at one time. If the signal is a subaudible tone, it may be transmitted continuously only as long as you are talking.

A 27MHz AM 4 watt transceiver that will also do VHF FM in the FRS band at .5 watts and a fixed antenna? :roll:
Nope, Frs and class D citizens band are two separate services, so not happening. You'd need one radio of each band. ;). 73, n9zas

Well thank you for recapitulating what I've written previously Captain Obvious... :lol:

I was simply pointing out the absurdity of the entire idea!

I think there was a Standard talkie, that was produced for awhile that included Murs, and Marine band or something like that but I never owned one. Not sure if it had frs or gmrs. 73, n9zas

Anyone have an opinion on this? I'd use a TK-880 for the UHF radio.

If you made a cross band repeater that included a CB radio then you would be remote controlling the CB by virtue of the other half of the cross band repeater. Although I don't find any specific wording on cross banding CB its generally not legal to do that between different services.

§95.655 Frequency capability.

(a) No transmitter will be certificated for use in the CB service if it is equipped with a frequency capability not listed in §95.625, and no transmitter will be certificated for use in the GMRS if it is equipped with a frequency capability not listed in §95.621, unless such transmitter is also certificated for use in another radio service for which the frequency is authorized and for which certification is also required. (Transmitters with frequency capability for the Amateur Radio Services and Military Affiliate Radio System will not be certificated.)


It seems a dual band CB radio is allowed if dual certified.

Guess that many of the newer CB radios are illegal that have the WX channels. Those are in another band near 2-meters. Thus, those CBs are multi-band radios.

They are certified and weather is receive only so I'm not concerned. I'll look up the FCC ID when their search form is working.

No, they are fcc type accepted because they have a secondary receiver for nws channels. They cannot in no way transmit there. 73, n9zas

The FCC is aware of the weather alert feature as noted on the grant. To be complete they could have added another grant under 15B for 162.400 - 162.550 showing no output like they do for scanners.

Not going to overthink this. MURS would be great for what you want, but the radios are scarce. Cobra 25's are good CB's, and most truck drivers have CB's in their trucks. Go with simple, quality, Cobra 25's and you are good. No, there are no "commercial grade" CB radios. Amazon.com: Cobra 25 LTD 40-Channel CB Radio: Car Electronics

And he's still wanting a portable solution. Like I said, it seems that the best solution is almost using someone to dispatch with a CB and UHF base.

Crossbanding a CB...there's some stuff that would have to be built. (Legalities aside).
