So let me ask a follow up question to this. If a radio can identify itself to a repeater and then the repeater can allow it access, can the opposite be true, as well? Can a radio be "banned" from a repeater by not allowing it's ID?

Update: It worked. I entered test mode and changed the unit to Mode 2. It now has the same range as the older units. Thanks for the speedy answers. I just didn't want to open the box and power the unit up if someone had already tried and did not have success. The new frequency range must just be listed that way for US sales... -Adam

Where I live is entirely different. I'm within range of 4 GMRS repeaters and I can go all day and hear nothing. One of them is mine and it's kind of a "stealth" repeater, but the other 3 are public.

I was just wondering if we we supposed to be programming our radios with an MDC tone, can anybody clarify?

Yes, I know I'm thawing out an old topic, but I thought it could use a refreshment. I have 4 repeaters on the air. I do keep a record of each repeater's users. Just not the email addresses. The "Run Reports" software as configured shows columns labeled Repeater Name, User Name and Callsign, Phone number etc. I am wondering if the columns labeled Number of Users, Requested Date, Approved, and Updated Date could be removed and put their email in place of them. Even if you couldn't download a .CSV file, it certainly would be easier than clicking on each approved member to glean the email address. What do you think? Doug Mitchell WROW 434

No, using Mobile Digital Communicator (MDC) signaling for voice on GMRS is not legal. The FCC prohibits all digital voice modes, such as DMR, on GMRS channels. MDC, though a form of digital signaling, is part of a digital voice system that does not conform to GMRS regulations.

Yes in Los Angeles If you want to send it to me at my address here on myGMRS with a prepaid return label, I woukd be happy to do it for you. Let me know your digital ID, too Is there no Ham Radio club nearby you in GA? Another option is to just purchase a preloaded OpenGD77 on a TYT-390 from Lets Get Ready Radios for $119 free shipping from Los Angeles (I do not get any commission): https://letsgetreadyinc.com/opengd390plus

I think the Open GD 77 cps is not set up correctly or is not a Valid one to use. Does anyone have one that does work and have everything needed to upgrade my dmr 1701?

STE is a separate function on Baofengs (and also RP-STE). This squawk I'm referring to is under Roger Beep. Anyway, around here, for ham, the advice is always to not use any of the stuff like that (STE, RP-STE, ANI-ID, access tone eg 1750). For GMRS, all I've seen is "don't use any DTMF codes on my repeater" (and of course, turn off the roger beep). My ham mobile can transmit my call sign (in CW?) but I don't use it in normal use.

PLEX wrote back and said the problem is caused when PLEX server does Library Scans on the QNAP which takes up unnecessary resources to communicate with QNAP. They have a recent update that solves the issue along with some other security isssues.. Installed the new PLEX server update it it looks like all problems with my COM Ports are now solved with Windows 11. No issues so far connecting my DMR radios to CPM.

I remember my first commercial handheld, it was the YAESU FTH7008. i purchased the radio since I was a Volunteer on Philadelphia's Operation Town Watch. Our group was one the first Town Watches to switch from Citizen Band Radio to GMRS. The one thing that I should have was obtain permission before purchasing the radio. I also wish that I had obtain my GMRS license, but I wasn't really active as I am now. I do remember our frequency was (462.725 / 467.725), I never really paid attention on the PL tone or Channel as GE used to use.

Nope. Nothing Illegal About It For Private Use. Businesses Use It Per Part 90 & It Is Also Legal For GMRS Under Part 95.

Mobile Digital Communicator. its en encrypted communications which is pretty much illeagle for public use. You can legally play with it on MURS or a business radio license.

DPL (DCS) Coded Squelch Repeaters Are Different On How The System Recognizes The End Of A Received Transmission. No Squelch Burst.

Reverse burst is usually generated on commercial 2-way transmitters to eliminate the squelch tail noise burst in systems using PL, or Private Line. "Reverse burst" is a Motorola term, and GE calls the same thing "STE" for Squelch Tail Elimination. Reverse burst or Squelch Tail Elimination ("STE") is a process that uses a change of the phase of the PL tone encoder for a short period of time after the user unkeys the PTT button. The term "reverse burst" is used to describe the deliberate phase change for a specific abount of time while the transmitter carrier stays on - about 150 to 200ms - with the phase of the PL encoder offset by from 120 to 180 degrees (180, naturally is a complete reversal). During the reverse burst time period the reverse phase stops the PL decode reed dead in its tracks - which slams the receiver squelch closed right now. By the time the transmitter actually drops off the air the RX squelch is already closed - which results in no burst of squelch noise being heard.

Correct. That Sounds Like A Squelch Burst. Most Repeaters Have The Option To Do A Reverse Burst To Eliminate The Static Sound At The End Of A Repeater Received Transmission.

That's the sound I referred to above as a static burst. I assume on my radio it's just a sound though, not an ID.

Don't Believe They Are. I Personally Don't Mind If Folks Use Them On My Repeaters, But I Do Not. May Sound Cool Like PD & FD - But To Me It Sounds Like Someone Is Pulling The Gizzard Out Of A Chicken From The Wrong End...... SQUAWK........

Baofengs can do that, but it's at least called something different, don't know if they're compatible.

No, Not At All. Kenwood Vertex Standard, Icom & Others Recognize This Type Of ID. MDC Is Commonly Referred To As The "Squawk" After A Transmission. There Are Also Other Types Of ID For This Purpose. They're Just Not Called MDC.

I thought that M might be for Motorola. So these guys are setting up repeaters for only Motorola users? That's the ultimate snobbery. I don't own one, never have, never will (don't like the company or the Motorola-only attitudes of users.)

MDC = Motorola Data Communications. It Is An ID Assigned, Programmed Into & Associated To A Specific Radio To Allow Transmissions On To A Repeater. It May Be A Pre, Post Or Both On A Transmission For ID So A Controller Can Recognize & Validate The Incoming Signal. Some Use It As A ID Only For Other Radios To Recognize The Individual Ttansmitting.

Motorola Data Communications

What is MDC? I don't think any of my radios have that. They do have other types of codes.
