If you need it legally, find somebody who already owns it and use their copy. You can no longer order it from Motorola. https://forums.radioreference.com/threads/motorola-astro-cps-r20-01-11-is-legal-to-use-if-you-can-find-it.454916/

The quiz thing is not unheard of. Local net used to draw Trivial Pursuit cards instead of the usual "how was your weekend" question. As far as I know, this wasn't advertised anywhere, it was just a thing the net controller decided to do.

Hmmm... government customer doesn't require FCC certification.

You might want to read about FCC's ultrawideband rules. You can transmit anywhere from 960-10600 MHz as long as your power density is low enough. This happened in the early 2000's, and is used in ground penetrating radar, and everybody's iPhone 11+. Again, no regulation has worked fine at 2.4...

Agree with using monitor or CSQ. If the issue is with the squelch, try the other TX deviation settings. Also try the DPL invert option.

Ham radio and GMRS is not public safety. I said that. It's a hobby. The benefits are learning and training, and giving those benefits to the widest audience. Ham radio and GMRS are not maintaining public-safety grade communications. It shouldn't be treated as such. Not true. AM is the worst in...

What you mean is telematics, e.g. OnStar. Nearly all new cars have telematics because the EU made emergency crash response mandatory starting 2018. Car makers realized they could have an ongoing revenue stream selling services like remote start, sending you ads the moment you're due for an oil...

Which is perfectly fine. Digital systems are very good at dealing with interference. Heck, P25's got 4096 PL tones. Look at WiFi. Everybody's sharing a handful of channels, we got baby monitors, video cameras, cordless phones, Bluetooth, cellular networks all sharing the same spectrum. Yet my...

I understand cruise ships often use PTT over WiFi systems. A network of 10-20 WiFi APs is going to be a lot cheaper than buying 10 repeaters. See the Icom IP series, but again if you're poor, an app-based solution is the cheapest and there's numerous ones available. Further, the infrastructure...

Keep in mind, this is a NOV. His repeater was broken and he should have had measures to stop it, both with equipment and via monitoring and remote control. He needs to explain corrective action. Intent would matter for a fine, which would be proposed in a Notice of Apparent Liability for...

What's "dead" mean? No lights? Won't boot? Won't transmit?

I bet the person filing the complaint was a user at the same site, most likely somebody with a public safety system, and probably Federal. The complaint was filed, the FCC showed up and got access to the radio within the same day. Those Radii aren't meant for 100% duty cycle, if it was stuck...

As mentioned on the Baofengs at school thread, P25 repeaters cost 5-10x that of commercial-grade LMR systems, for fundamentally the same thing. Especially compared to DMR systems that give you 2 talkpaths in one unit by default. A question: why are the Baofengs inadequate for your needs? Poor...

I play loud music in my club, and an officer comes in and can't hear his radio. Is that a crime? Anyway, this has nothing to do at all with my real point that any detection method is becoming irrelevant when everybody's car now is required by law to have technology to measure the speeds of...

Nope. As you say, it's the intent of the law. The laws were intended and are applied to things like physically getting in the way of a police officer during an arrest. The laws predate lidar. The fact that states have anti-jammer laws only supports my argument. I didn't wash my car, so my...

If that applied, they should have arrested everybody who worked at Nextel and had a Nextel phone.

States would have to pass a law making laser jammers illegal, and only a few states have that. For radar jammers, the FCC already has authority under the Communications Act. In fact, RF jammers are banned under CFR regulations, so they could seize one under a warrantless search (inspection), and...

You mean MyView. They stopped updating MOL.

Yeah, lidar can be jammed legally since there's no FCC for light. What the new thing is simply to use radars that are very similar to vehicle radars. Two common systems in use are known as MRCD and MRCT, they use the frequency-stepped radar that anti-collision systems use, and being...
