As part of my recent deep dive into technojunk, today I am writing about GMRS (General Mobile Service Radio). You know, those inexpensive walkie-talkies that advertise a 20 mile range. But, before that I am going to update my status with my other endeavors in this arena.

Since I am coming back from a long weekend of hunting, I am writing this ahead of time. At least at the time of writing, I have successfully installed the driver for my SDR (Software Defined Radio). I can hear consistently broadcast FM stations. I am still working on installing the program that I want to run on Linux called SDR++. Eventually, I will need to add a second SDR in order to make the scanner work.

I also purchased a CB last week. This is a great tool if you are going to be in the woods during the week. The reason is that it helps you stay in touch with what is happening. Log trucks are on the CB frequency and I don’t know if you have ever seen the roads, but you don’t want to come head to head with a semi truck. This will be my entry into CB because you know it takes two to communicate. I have plans to add more radios. One final reason that I did it was because my dad has a CB and so I think it offers communication is an area that phones will not work.

When you buy these inexpensive walkie-talkies and read the instructions, it says that there are some frequencies that require a license. FRS stands for Family Radio Service and I already said what GMRS stands for. But what does it mean? Well, FRS frequencies are from 462.5625 to 467.7125 MHz and GMRS is 462.55 to 462.725 MHz. And what it really means is that these walkie-talkies can operate on both spectrums. Furthermore FRS is open like CB whereas GMRS is supposed to require a license.

As far as I know, no one has ever been prosecuted for using a GMRS frequency without a license but you should know before you use those channels what the expectations are. I am not entirely sure why they actually require a license to use, but regardless it is a pretty low bar of entry. The license only requires paying a fee and it is good for ten years. I am thinking that I will just go ahead and get the license.

I have been aware of this requirement for a long time. My frugal solution was to stick to channels on the FRS band. Over time, I don’t have all of those channels and frequencies memorized and I don’t remember what I should and should not use. I think that the cost of entry is pretty cheap and if I am thinking of going further into radio I might as well be above the board.

In case you didn’t get the title innuendo, you have to go back to the mid-2000’s to the song Ridin’. “Try to catch me ridin’ dirty.” I heard this phrase when I lived in SC and it means driving without tags (or legally). That is what it is talking on GMRS without a license. Anybody can buy a radio and in theory start using it. This is also true in the ham radio band in the 144.0-144.1 and 219-220 MHz. That is the honest truth, while it does require a license to use these radios, there is nothing stopping you just like speeding.

Generally, I am not for most sorts of regulation. In this case, it probably isn’t a bad thing. I don’t know if you noticed, but GMRS and FRS overlap in their frequency range. What if you started broadcasting over the cell phone range? We have collectively agreed that there should be some boundaries in use of the electromagnetic spectrum for purposes of safety and privacy and even exclusivity.

I know that it is strange to hear, but not all government rules are useless. It is the purpose of the federal government to setup rules when common interests overlap. Some of the intent of the mission is to keep noise off of frequencies used for safety and security. I think that we all want the ambulance to arrive in our time of need. They lose their way when it comes to administrative power and enforcement and move beyond scope of purpose.

I realize that I went kind of technical today. For me, I am learning so much about what things use what frequencies, it is kind of like assembling a puzzle. I will try to keep the jargon down to a minimum in the future, but I may do a more technical post so that I can refer to that as a baseline.

End Your Programming Routine: In the end, I don’t really care whether you use the GMRS frequency without a license. I feel like the radios are so inherently limited in range and usefulness that it really doesn’t hurt. I have had trouble using them from car to car on a road trip, so it is a really localized problem and whatever harm can be had by improper use is pretty well contained. That being said, I feel like it is my duty to investigate the process, benefits and drawbacks.
