CB is for the people wanting to communitcate on a every day manner, not for use to support companies. There are commercial licences for a reason, and im not saying for the to "F**k Off" entirely just F**k off the Inputs and leave the repeator for every one else that uses radio's for a hobby. Their use of the Input disables many people using the repeator. As I was once told and now am trying to live by "Simplex Rules!!" Meaning you wanna communicate use a simplex (for naighbourly use or for business use). This Limmits the Range of the Commercial users. Congrats to them that they have come on the radio wave scene, but leave the business use to a commercial radio. Before i go ill leave this for you to ponder, If commercial are MENT to be allowed to use Citizen Band, why is there a commercial licence out? Appart from the revenue the government makes its to littim the traffic tramsmitted on public stations.
But that's where you are wrong ... CB IS for commercial companies to use for their own benifits in EXACTLY the same way that you use it for your own benifits.
The law say you get treated equally, there is not one special rule for you and another for somebody else.
The same can be said of hobbiests using CB radio... if you want to use radio for a hobby, get a Ham radio licence ... just because your too stupid to pass the test is no excuse. Oh... but it's a different story when the shoe is on the foot, comercial operators have money. Bzzzzzt. The law does not descriminate against them because of wealth nor does it descriminate against you for intelligence or lack of it.
The problem is one of education. In ham radio there are also no "rules" as to how the bands are used, but there are "understandings or agreements" like the first 100KHz of a band on harmonically related frequencies is used for weak signals like EME. Satellite segment, packet segments OR repeater inputs.
The difference between ham radio and CB is that the users are educated. They go out of their way to not to cause trouble.
In the case of CB, no such effort is made on the part of anybody. In MOST cases, it is normal to say "fvck you" and carry on reguardless.
It's not just commercial opperators, it's any user particulary repeater users.
So when a naive crane operator uses ch31 today, it's a matter of not knowing kind of negligence, as opposed to the repeater users who comes down to ch31 and abuses and jams the crane opperators rather than doing the right thing.
The right thing would be to contact the commercial user and explain to them that channels 5, 31-38 are allocated for special use and that their use of such channels causes problems for other users of the band. In the case of somebody like a crane operator, you jamming them could see you end up in court both state and federal (ouch) for multiple charges if you cause an accident. Contacting the union/company and highlighting the case that using CB (especially on those channels) has the potential to cause accidents.
An example that happened a few years ago, my Hang gliding instructor uses CB radio for his operations to talk to student in the air. He puts the CTCSS on to make it more secure. He's quite aware of channel allocations, but that didn't stop some fvckwit jumping on the channel and giving a student in the air wrong and dangerous instructions.
This had the potential to kill the student, something as simple as "turn left now".
So I dragged out the RDF unit and found the guy and reported him to the cops. They took all his radios as punishment else he prefered to face more serious charges in court.
Hang gliding instructors and most other commercial users of CB are small time operatos who cant afford the big ticket licence fees that come with owning, operating or using a private channel. Those that can afford it or need better security do use private channels.
Bottom line is they aren't doing anything wrong, and it is you acting illegally by insisting that they don't use the band by depriving them of access.
Using ch31-38 simplex isn't illegal, it's just not recomended. Might I suggest you try education, either of others least not yourself ?
