Given how small the screens are you almost have to hold it up close to see anything. The one thing all these laws show are the people who write them have little to no technical or operational knowledge of radio usage. Further what studies do they even consult, if any, to justify some of the stupid provisions in them. I just have to laugh when watching YouTube videos of cops in a high speed chase doing 90+ MPH driving ONE HANDED while calling out direction and road intersections on the radio. You can clearly see it in the body cam footage. I sure would like to know what course they took to learn how to "safely" drive like that, one handed using a radio, while the rest of us are considered a road hazard.

This also explains why manufacturers went to digital for the very narrow band channel setting, 6.25KHz, which at some point the FCC might mandate. The manufacturers claim FM using anything less than the current 12.5KHz channel spacing isn’t practical and the only way to achieve it is through digital voice technologies.

It’s a bit more complex than the above. Narrowband vs Wideband.pdf

This is exactly why the law is very poorly written. Leaving it up to the cop or judge to make a technical determination is not how the law should have been crafted. There is no “objective” standard and leaves it to the personal option of the officer or judge. That’s how laws get invalidated. Just to make it clear the law as written ONLY mentions some part of the upper body holding or supporting the offending device, nothing about the legs. I mention this because on more than one occasion I’ve had Hams tell me they send CW while driving with a Morse key strapped to their thigh. Dah?! That’s OK while a wireless BT speaker mic isn’t?

Stalin’s head of the KGB once said “show me the man and I’ll show you the crime.”

I’m guessing it’s a homemade repeater that went on the fritz. That’s why there should be a TOT, time out timer, on the transmitter. Also there should be a repeater control operator monitoring it too. The later should have the ability to remotely gain control of the repeater and disable it. I’m reminded of another story on the Ham band. There was a similar case with a continuous unmodulated signal. That case was tracked down by some Hams using DF techniques. The cause was the mobile radio’s mic got stuck in the seat back somehow where the PTT was pressed in. The owner never noticed.

No doubt about that point.

If the law is written in such a matter where it’s vague and subjective interpretation that varies from officer to the next courts have found these laws invalid and or unconstitutional. It seems to me the law is arbitrary without logical reason for the distinction.

I’ve had good luck with Kenwood radios. Most allow programming for wide or narrow band FM. My typical GMRS carry radio is the TK-3170. https://pdfs.kenwoodproducts.com/9/TK-2170&3170Brochure.pdf

So how does my remote control Bluetooth speaker mic fit into the picture? It seems technology is a step or two ahead of the law and it hasn’t even gone into effect yet!

If anyone is interested the attached brochure has the various models shown. Otto Professional Surveillance Kit.pdf

I don't care much for anything that sticks in my ear either. Mine are rather sensitive. After a few hours the ear starts to hurt a lot where the insert is located. The "D-Ring" is comfortable to wear for long periods. I don't much care for the lapel mike location. I have another ear headset that is a multi wire design. There is a long wire you run down your sleeve. The mike and PTT are on that.

That fits several model Kenwood radios I have. Those use the universal connector side port. The rest of them use the typical "K" type connector you see on the cheap Chinese radios. The universal connector is billed as being pretty much water proof compared to the "K" style. The negative with the universal connector is one of the pins can be energized with 5VDC which is used for some of the GPS and noise canceling enabled microphones. If you're not using an external speaker mike you need to have the side cover installed or you could short out the pins and wreck the radio.

All kidding aside I like the “D-Ring” ear hanger type better. Nothing to stick in your ear and my experience the sound quality is much better.

Need a Tee-Shirt with FBI stenciled on it too to enhance the effectiveness.

Yes, it is a lot to digest. The first chapter is likely all most people need to read. The bottom line is worrying about the different between an SWR of 1:1 verses 1.5:1 isn't worth the trouble.

From the looks of things I would say they are serious. However I'm shocked these people will bet their life on a cheap $25 Chinese radio. It's not like they went around begging for free radio handouts. From the money they spent on the weapons etc. they certainly can afford better quality radio gear. At least get something with good encryption, like AES256, if they're worried about the government spying on them. A cheap UV-5R isn't it.

Like these guys? https://radiofreeq.wordpress.com/2016/01/19/militia-radio-frequencies/

That's discussed in the book at the following link. http://www.w3pga.org/Antenna Books/Reflections III.pdf

That's cool. Looks like you're primarily a Motorola guy. I have a few XPR-6550's and XPR-6580 (CPS hacked to put it on 33cm band). You check my album out you can see my collection.

Which radios and models? I'm mainly a Kenwood guy myself.

Well at least we know where the Chinese are earning their bribe money.

Wow and that even rimes! ?

I typically saw the orange or yellow plastic ones. You mean like this one?
