two different MDC acronyms. I'm referring to Motorola Digital Communicator.. So yes i 'get it' Motorola Data Communications is acceptable. I'll still stick with MAGA though

Tried to connect the new tones and nothing info on when it's going to be back up?

YEP, that did the trick! Don't know, "why it worked," but can guess there was something in the internals that prevented the access either to the channel selection of the Tone selection. After recording all my setting in the MXT-400, I did a RESTORE function. The RESTORE function reset the internal components back to factory setting. I input all my previous setup options and it works like a charm!

A Better Term Would Be That Repeater Access Would Not Be Allowed. So In Short - Yes. It Could Disallow Someones Use Of A Repeater.

MDC Is Legal For Use On GMRS. MDC Is A Motorola Brand Name For AFSK - Auto Frequency Shift Keying. See Definition Below: AFSK Encodes Digital Bits Into Two Audio Tones To Be Transmitted On Analog radios. § 95.1777 GMRS tone transmissions. In addition to audible and subaudible tones used for receiver squelch activation and selective calling, to establish or maintain communications with specific stations or to access repeater stations (see § 95.377), GMRS transmitters may also transmit audio tones for station identification (see § 95.1751). § 95.377 Tones and signals. Personal Radio Service stations that transmit voice emissions may also transmit audible or subaudible tones or other signals for the purpose of selective calling and/or receiver squelch activation. These tones and signals are ancillary to voice communications and are considered to be included within the voice emission types, e.g., A3E, F3E, and G3E. (a) Tones that are audible (having a frequency higher than 300 Hertz), must last no longer than 15 seconds at one time. (b) Tones that are subaudible (having a frequency of 300 Hertz or less), may be transmitted continuously during a communication session.

Line A is still a thing. What has changed is GMRS frequencies are no longer part of the restrictions. I still have multiple FCC frequencies for public safety being held up in Canda.

Yes.

Hello all, I recently got a Ailunce HA1G radio and have been trying to get it working with a PTT ID required repeater in my area. Everything I have tried so far has not been working. I sent up the repeater channel, added my assigned ID to own ID under signal settings (or call ID if your programming via CPS), set to BOT at 300ms and set the channels signaling setting to one of the dtmf signaling lists I have. Anything I maybe missing? Any help on things I may be missing or tests I can do is much appreciated.

My At-779UV does the red blinking light thing too. I just jiggle the mic cord and it resolves. Haven't had the audio issue described.

Might be a dodgy connection from the mic cable? those RJ-45 connectors aren't the strongest things in the world. If you jiggle the connector at the radio does it happen? I've noticed it do weird things if I disconnect or connect the mic or programming cable while the radio's on.

I'll have to let the repeater owners explain how it works on repeaters. My ham mobile can block incoming signals based on the tone, but that's different from an ID code. I don't think any radio I have can decode IDs even though they can transmit them. [A newer radio I have has an encryption function but it isn't legal to use so I can't even test that.] All my radios are analog.

[The cutesy title is a play on the brand name.] Just had an unnerving occurrence where no sound was coming out of either earphones or the radio speaker (receive LED and signal meter did indicate it was receiving). I tried all the relevant settings I could think of to no avail. After giving it up for broken, I tried turning SUB back on and switched to B -- boom!, sound blaring out. Switched back to A and sound there too. And it worked with earphones too. Doesn't make sense but I'm glad it started working again (no signals to test with right now). The other odd thing I've noticed is the red TX LEDs will come on briefly at random times when I'm not touching the radio. No pattern to it that I can discern so far. And the mic is hanging up where the PTT button is not touching anything.

I mean, "obvious" is a strong word, but yeah, it's certainly logical. I was just making sure. I assume that's not something that analog radios are able to do? You'd need a digital radio, yeah?

While you're waiting for 702's reply, I'll say that if specific IDs are required, then would it not be obvious that revoked IDs would be blocked? But for the official procedure to ban someone, the owner is supposed to send a letter to them (probably after telling them).

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.
