VHF vs CB
#31
I ran into the guys from Rugged Radio at an event. I inquired about frequencies that they have programmed into radios they sell and the need for a license. They initially made it sound like anyone can use them without a license, but when I pushed a little more they said they sell radios to race teams with itinerant licenses and those radios they sell to the public they assume are being used to eavesdrop on race teams and that buyers should not transmit unless they have a license. It sounded like they were trying to cover their butt when I pressed them on licensing requirements.

This is the license for 151.715 which is BFG relay, as you can see if you use it anywhere outside the area it is registered to you will be interfering with businesses.

The database at the FCC site for the above mentioned frequency did not match up with what you showed above.
Thanks, and trying to do more research on these radios.
We don't want to interfere with someone doing business.
I am going to look into a 4x4 club that is a 501.c.3, if they an get a business license to use 1 or 2 frequencies.

That may be a good idea if you can find a club to pay the fees and regulate the radios to be sure they are Part 90 compliant. I don't think all baofeng radios are part 90 compliant.
Applications requiring frequency coordination in accordance with § 90.175 must first be submitted to the proper frequency coordination committee,
which will subsequently forward them to the FCC electronically. Access the WTB internet website at http://wireless.fcc.gov under Wireless Services
for frequency coordination committees and their mailing addresses or you may call the FCC at (877) 480-3201 (TTY 717-338-2824). Applications
and notifications of certain radio services are required to file electronically within Part 90 Land Mobile Radio Service. See § 1.913 on mandatory
electronic filing. NOTE: Applicants may apply to operate at different permanent locations, provided that the different locations are an integral part of a
single system, when licensed under a single call sign. Each group of six permanent locations constitutes a station to which a separate application fee
will be required. The instructions that follow are for filing applications. Select the purpose of filing and follow the instructions below:
Frequencies below 470 MHz (except 220 MHz), 902 – 928 MHz & Radiolocation and 3650 – 3700 MHz Band (PMRS)
New, Renewal or Renewal/Modification,Intelligent Transportation Service
FCC 601
FCC 159
Application Payment/Fee Type Code: PALM - $70.00 Fee AND
Regulatory Payment/Fee Type Code: PALR – $100.00 Fee (Per Call Sign)
cheaper for you to just study for your ham and pay the 15.00 for the test.

CB is open area communication while those 2 way radios you mention are for short distance or more obstructions. Ideally there would be a HAM radio that includes CB, hopefully there will be one day. There are limitations for each type and that's why you don't find a radio that can do too many different bands. A little antenna theory would go a long way. A similar sized antenna would be closer to wavelength for things like GMRS and FRS radios while being a fraction of the wavelength of CB (which is around 11 meters, that is the full wavelength size antenna, I doubt you have a 11 meter antenna on your Jeep). That being said, where CB trumps shorter bands (2 meter to 70 cm) is over longer open areas. An easy way to imagine it is the smaller the wavelength the more it can penetrate but can be lost over distance. The longer the wave length the more it blankets an area offering the benefit for long range flat area (typically found in long road situations). Also the CB signal can bounce giving it over the horizon abilities the smaller wave length can do. I hope this wasn't too difficult. I would recommend a cheap HAM radio and if you don't want to get a license program it for GMRS/FRS use. In a disaster in which life depends on it you could crank up the output thereby improving its range.
I have been using CB radio for about 2 years now and find that I can communicate with most anyone on a run. And then some people (without a license it seems) uses some VHF radios from Yuasa, mostly handhelds. I guess really it is a group decision and the frustration is not knowing what the group wants to go with ahead of time since some of the runs, I meet new people. Once I get a good group, I can see the benefit of a better VHF or GMRS system, but until then, seems CB is a good compromised choice. Unless anyone has any other suggestions?

You make it sound as if all you have to do is find an unused frequency and squat on it. That isn't how frequency management works. As the post you quote intimates, frequency management is a living thing. Frequency allocations change constantly depending on a lot of specialty activities--for instance a race, military exercises, etc. There is a VERY limited set of bands that are usable by those without licenses. And I expect you're fully aware of what those are. You may as well accept that all other frequencies are managed, and transmitting on them is restricted (sometimes so is even monitoring them). Stop searching for that "unused frequency" and get a license, then stick to the terms of it!

First is that unless the end users understand antenna theory they are unlikely to have their antennas correctly tuned and this will have awful performance from their CB's. They may not be able to hear others in the group. They may sound like Charlie Brown's teacher when transmitting.
Second is that a VHF or UHF radio will be operating using frequency modulation as opposed to a CB's amplitude modulation. This makes a HUGE difference in the real-world utility of the units. Think about the difference in sound between AM and FM bands on your radio....
Also the CB signal can bounce giving it over the horizon abilities the smaller wave length can do. I hope this wasn't too difficult.

This is by far the best post in this thread. Very good summary if someone is looking to what direction they want go.
