This goes a long way to explain why you don't see more in the way of TETRA systems here. https://www.powertrunk.com/pressroom/tetra-in-north-america/

Those are generally mutually exclusive. It can listen on those frequencies, but depending on model, can't receive AM transmissions. And the cheapo ones generally can't.

Brand new to radios of any kind except cheap blister pack radios for the kids. I got a cheapo baofeng to mainly use to listen too in emergencies, or God forbid maybe call for help one day. But it's basically just for the hurricane kit. I won't bore you with a whole program file but what I did was make one side of the channels 1-50 national "universal" frequencies. I have all 22 GMRS/FRS channels, I have the important civilian marine VHF channels since I live on the river (9,13,16,22,68,68,71,72), I have the 5 M.U.R.S channels even though I really dunno what those are, I have the national simplex calling frequencies for 146, 446, and 223, the international space station because why not, the airband emergency channels such as vhf guard, the 2 air to air ones, the helicopter to helicopter one, the air search and rescue one, the military uhf gaurd, and finally something called VSAR16 which I believe was ground search and rescue..... Does this sound like a good comprehensive list? Anything I'm missing as far as universal nationwide frequencies? I have the local stuff on the other side of the channels (999 and down) to make them more organized. I won't go into that list, I'm just focused on the national stuff first. Thanks in advance!

This the most current version of the CPS I could find on-line in the attached photo and have installed. I think I saw a reference to a V3.09.13.406 in the link below. So far I can't find a place to grab a downloadable copy. https://www.ebay.co.uk/itm/267314153152

Depends on the price. I'm cheap.

Thanks for correcting my miss understanding.

I agree with all of your comments... Especial having it be the courteous thing to do. Some of my posts can get a bit spicy, so I feel it's important to point out that while I am having a conversation about not needing permission from a legal or regulatory standpoint, I do agree that it's someone's personal belonging, that we are using (or asking to use), and as a civilized society we should be mindful and respectful of that.

We are discussing GMRS, which has different rules, but for the sake of discussion... First, why would I be on those GMRS frequencies. Well, to use the repeater that the owner may otherwise want you to ask for permission, or any other repeater on the same frequency. There is a lot of overlap in the DC metro area. I can be heard on 3 different repeaters on .600 in my area when I am only using 20w. Also, fixed stations may transmit on those 8 channels without going through a repeater. I disagree about the interference and trespass concerns based on the FCC rules for Amateur Radio and trespass laws. If I am using a repeater without the owners consent, I am not causing interference nor trespassing. Use of the repeater itself is not causing interference. Intentionally talking over people and making it so others can't use it (or the frequency) falls under the harmful interference rules, which would be different than needing permission. Again, there are no laws that I have been able to find implying trespass on non-real property. I have two points to debate on this comment. Again, you are referencing Amateur Radio, not GMRS. There are different rules. Additionally, there are only 3 letters I could find that were issued to amateurs in the last 10 years for using a single repeater. All 3 letters were sent in 2017, went to 3 different people, and the complainants were the same person/trustee complaining about 3 people causing problems at or around the same time, preventing the trustee and club members from using their own repeater. So, there was a lot more to it than just not having prior authorization to use the repeater. With regard to GMRS, I cannot find a single direct warning letter for GMRS repeater use refusal. Not one. Meaning, there are no publicly available FCC warning letters or Notices of Apparent Liability that mirror the amateur radio pattern above, i.e., issued to a GMRS operator for continuing to use a repeater after being told not to. FCC rules clearly grant GMRS repeater owners control, but enforcement is murky at best. According to Part 95 rules noted in an earlier post, a GMRS licensee “may disallow the use of its GMRS repeater by specific persons as may be necessary” to carry out responsibilities under the rules. This implies the owner can refuse access. However, there’s no record of the FCC stepping in if a GMRS user ignored a private owner’s request to stop using a repeater, unlike the amateur (Part 97) precedent. Also, in 1999 the FCC issued a formal opinion in WT Docket 98-20, 96-188, RM-8677 and RM-9107 (https://docs.fcc.gov/public/attachments/FCC-99-139A1.pdf) about implementing a rule to require users to get permission to use a repeater 'prior' to repeater use. It has not been brought up since. Here is the text... "...repeater operators ask that we require users to have permission before using others' repeaters. We decline to adopt such a rule because it would interject the Commission into a GMRS licensee's private management of its GMRS system, including its repeaters. Such a rule also would be inconsistent with our efforts to eliminate unnecessary regulations and burdens for GMRS licensees and applicants. We emphasize that users are free to take steps to prevent unauthorized use of their facilities, including turning the repeater off as necessary, limiting or disabling receiver sites, and using tone-operated squelch or digital access codes. Moreover, the rule suggested by petitioners would do nothing to change access to repeater; even with the rule, an unauthorized user could cause a repeater to transmit, absent some engineering solution to limit access to the repeater input." Short of a new opinion from the FCC or a rule change, this very clearly states that GMRS repeater owners are on their own if they want an operator to stop using their repeater.

Well, @Lscott wants one. He just said he’s looking for one. Why would you put it on eBay. Just sell him yours.

Thus my comment “for whatever good it does.” Kind of a here are the rules and guidelines now you all figure it out amongst yourselves while we here at the FCC attend to more important things approach. This wasn’t lost on me. I was just pointing out the wording of “may disallow” indicates you have the right to ask someone to leave, meaning they need your permission. As @OffRoaderX has pointed out many times, enforcement isn’t. The rules are what they are. Enforcement is or isn’t what it is. Manners and social decorum, respect for others, what do we have without that? You can’t force people to act like good humans. It’s better for everyone if we do. Does this change your mind?

Easy enough to roll through all the tones late at night. No one knows you are doing it until you hit the correct tone and then you can stop.

Pt580 Nice Radios. I have one.. It might show up on Ebay some day - If they let me :_)

I doubt that you will get an answer from him since he only made two posts to the forum back in 2021.

You can program Part 95 certified radios to listen on the repeater input frequencies too. I have found that I had to use programming software to do this. I have our GMRS repeater input set to memory on my base radio and a few hand held radios. I have done it with my Wouxun radios using the Won software and with the RT Systems software. Setting a radio to one of the repeater channels and hitting the tone scan will only scan for the repeater output tone. If someone goes through the trouble to program a repeater's input frequency and scans for the input tone just so they can be an ID10T is a total Richard Cranium move in my book.

Yes and no. The NX-5000 radios come with DES 4 key option out of the box, and those keys are software loaded. DMR Enhanced Encryption (ARC4) is an add on, but those are also software loaded. If you want AES, or more than 4 DES keys, you need the AE31k crypo module, then AES & DES are loaded via either hardware keyloader, or KPG-AE1 software. NX-3000 don't have anything out of the box. DMR EE is same as 5000, add on + software load. AES/DES need crypto and hardware or KPG-AE1 software. Kenwood VP8000 & VM8000 are entitlement based encryption, hardware is in the radio by default. AES/DES is keyloader or KPG-AE1, EE can either be done in programming software, or loaded via keyloader. I did have an issue with hardware loaded EE keys though.

Shaw was 100.0 TX only. Is it different now?

I downloaded the CPS from the Baofeng website. The issue isn't the computer or my operating system. The CPS doesn't allow a COM Port to be picked so it can't connect with the radio. I've had no problems programming my other radios so that wouldn't be an issue either. I enjoy setting up radios and have spent hours doing so. You've got to be able to connect to the radio to do anything and without that you're dead in the water. I loaded the CPS for the RT-4D, opened it and can select COM5 so I'll be able to connect to it when it gets here. I'm not doing any Firmware upgrades or switching to Open GD77, I'll run what came on the radio and be happy with it.

Exactly. But I believe that getting permission is the courteous thing to do. So, to summarize, if someone uses your repeater without permission, that’s not a rule violation. Repeater owners are responsible for ensuring that people who use their repeater obey the regulations. Repeater owners must find a way to deny access to someone who violates regulations while using their repeater. Repeater owners are in a tight spot.

Right, nothing prevents a person from listening on the input frequency for the input tones. Of course it’s easier with an opened up radio than it is with a 95E certified radio.

That's true. However a number of people on this forum also hold Part 90 licenses where it is legal. Unfortunately I'm not one of the lucky ones who qualify under the FCC rules to get one. Not exactly a topic for Ham or GMRS, but legitimate for the proper service. Don't forget that a fair number of commercial grade radios already have encryption built in. Just can't use it on Ham and GMRS. Of course when the SHTF, and government reg's are out the window, encryption might be the one thing that will save your butt from those that want you and or your stuff.

That makes it easy. One other forum member has some Kenwood NX5000's and he needs an external hardware key loader. The keys are store in a computer file, I believe, in an encrypted format for security. That's all handled by the key loader software. Many of my older Kenwood digital radios have an option board access port on the back side for plunging voice scramblers and digital encryption options. I've also found some info on the add on encryption used my some of the Kenwood radios in case anyone has an interest. I also have the hardware manual for a third party Voice Inversion Scrambler with Midian’s Kryptic Signaling with the schematic.

Since you know that its not legal on gmrs, then why are you using it there? Sent from my SM-S911U1 using Tapatalk

Encryption is not allowed in the USA amateur service. Businesses licensed in the business band are allowed Encryption. Sent from my SM-S911U1 using Tapatalk

You cannot use the repeater input frequencies unless you are wanting to access a repeater. So. You are deliberately interfering with or trespassing on a repeater if you access it. Now....if you are on the repeater *output * frequency, talking simplex, then you are good. The fcc has taken action against those who have been banned from (ham) repeaters. Usually, a single notice of violation is enough to keep the offending party off the repeater. Sent from my SM-S911U1 using Tapatalk

I've never had it happen, but I only just now posted my repeater as "open" so it's possible. I've been listening to all the repeaters in my area for months, though, and I haven't heard anyone being abusive, so I decided to risk it.
