Hi, i'm looking foward to buy TK-2207 Radios. It's for very light use (talking between pit and my pilot at my local speedway). The only thing I want to know, is if we need lisence to use Frequency range 136-174MHz? Or do we just program it at whatever channel we want in this range and we are good to go??
Thanks a lot!
Well, you have options. You CAN use
MURS, but MURS can get crowded and out of control making your communication intermittent. Probably not what you want while you're racing. If you do select this, and it is the path of least resistance (that's legal), use a good CDCSS code that's somewhere in the middle of the list so that your chances of having someone else break through are minimized. Try this one first. It's free and it might work fine for what you need.
You can get a license for
itinerant business frequencies. These are shared and depend a lot on where you are. The objective is to license a few and pick the one that has the least interference on it -- or -- cooperate with others on the channel.
If you're racing in one particular venue, you can get coordinated (through a business radio license coordinator) and licensed (through the FCC - both frequency coordination and submission to the FCC are necessary, the coordinator will send your application through for you) on one particular set of frequencies that are set aside for you and maybe a small, manageable number of other radio users who won't interfere with you. Most people do either this or the one above.
In the end, only you are responsible for the course you choose. If you just set up wherever, you might be okay for a while, or you might have some consequences. Some of those consequences could very possibly draw undesired attention to you, cost you money you don't want to spend, and/or get in the way of other goals you might have.
Good luck, be safe, and win lots of races!
