Not easy to find someone doing intermittent keying. But to just play music? Just sending out a beacon saying come get me.

I can tell you that the repeater association (ham, not GMRS) I belong to had been dealing with someone transmitting music every night at the start of a pretty big daily net. Months of it happening, repeated complaints to FCC and zero action or even a response. A little harmful interference is nothing big to them. It took tracking them down and knocking on their door to ask them to stop while handing them copies of the FCC "rules" on such matters. It stopped. Not because of the FCC rules, but because they realized that you can be found.

That's about right. It gets more complex if you want to start jumping between linked reperaters by "dialing" into them, A.K.A. Reflectors. https://www.vkdmr.com/using-dmr-reflectors/ https://pnwdigital.net/c-bridge-network/ Getting confused yet?

Something good the guy in the video did was look up the repeater call sign to see if the info on repeaterbook was current or not. If you watched the video you'd see that the CC of 1 was wrong and the current CC was actually 4. I have 2 or 3 DMR repeaters that I can use locally and a few others that are out of my area but places I may travel to that I'll probably add. It really isn't much different from analog, just more steps to get to where you want to be. If you take each step in a logical order and not get ahead of yourself then is should work out ok.

If the repeater had a DTMF decoder you'd put it on BOT and have that along with the repeater tone for double security.

Can the PTT-ID (or similar) be detected by the repeater and used as a filter, like a tone? If so it would be a one way to limit access on a private repeater used by a small community -- would not work for something large as the ID would eventually get passed around.

I bought one about a year ago. I had it replaced because it was going through some weird power on-off cycle when he PTT was pushed, but the replacement has worked fine. It was on sale for $5 less than the 20 and had good reviews (thanks Randy) and a few more features.

The problem I have mostly is discovering what talk groups are supported. There is no central database for DMR repeaters that has this info. Usual you need to search on line for a web site for the repeater, if one even exists. Then, what info you do find is likely outdated, talk groups no longer supported, new ones added and which of the bunch of DMR networks it connects too for linking etc. For some repeaters the setup is fairly simple, others it's a huge PIA. See attached file for an example. The best practice I found, if your radio supports it, is grouping everything by repeater in a zone for just that repeater. Then one channel memory is programmed for the particular parameters required for one talk group. You can have a few to dozens of entries for just one repeater. See attached photos. This is for my NX-1300DUK5 radio. https://forums.mygmrs.com/gallery/image/290-nx-1300duk5/?context=new N8NOE DMR Repeater.pdf

By “silent RX” do you mean the LED is coming on but you don’t hear any audio or do you mean you hear the carrier but there’s no voice? Keep in mind that not only repeaters transmit on 462.625 MHz but also people using simplex channel 18 for both FRS and GMRS.

Good morning. I am trying to set up my data bank for repeaters that I use/may use I Am in Quincy/milton mass area and I am getting a silent rx from some .625 repeater (I am using midland mobile mxt 15watt with midland roof antenna. ) I can't find any influence info on any repeaters on the what might be sending this phantom signal...oh...btw... test freq reception at granite links golf... way up high above boston. Thanks for the help.

Some types of radios are nearly impossible to find. I don't blame you for keeping it.

Any idea on actual output power in the 900 MHz band? I always scoff at the handhelds claiming 8 Watts, in a radio that size.....and when tested it is only 3-4 Watts and then drops off quickly to something a lot less than that. I like the displays and the layout of the radios though. Seem a lot like my Anytone 878 variant.

that was just a sarcastic snark remark against Ebay.. No way i'm letting loose of that radio and i'm pretty sure @Lscott knows that.

DMR ID/check I also need the frequency TX/RX of the Repeater I'll be using and I can get the Talkgroup/CC/TS from the Repeater info. Zone will be named "Digital" in my radio. I'm going to watch a couple videos to get more of a handle on things. This one looks pretty good at explaining things.

I have most vers but they are sitting on my server at home.. I'm away camping for couple weeks. What vers are you avter? I would stay below 8's because anything above excludes the motorola stuff due to lawsuit.

yes, you are right. how you write your add is the trick..Avoid speciic model number keywords because thats what they flag. Better to use detailed pictures with heading like Hytera Repeater instead of Hytera RD982 Repeater. According to my friend, Ebay flags specific Model Numbers basted on the information they get. Doing a serardh for Hytera mobile, transciever, repeaters or land base radios brings up the adds. A little more work for some of us looking for specic equipent but it is what it is.

Don't worry, you'll get used to OffRoaderX (or you can set the forum software to ignore his posts). I think he does this stuff for the attention - after all, "making contact" could be something as innocuous as asking for a radio check.

No, it doesn't. I also looked at the DB-20G. I ultimately went with the 25, not because of the additional power but because of the ability to quickly cycle through four channels instead of only the two available on screen with the 20. We have a dedicated channel for family communication that is always at the top of all of our radios. And then a local repeater under that, a NOAA channel, and then the last one is for simplex channels. If that doesn't matter to you, I'd go with 20, too. But the 25 does look cool and you can have a custom welcome screen.

Adding DMR channels is different from entering analogue. You need 5 things for a digital channel, your DMR ID; a talk group; zone; color code; and time slot. Groups such as Parrot should be also set as a PRIVATE call to avoid blasting the zone with your test message.

Welcome John

Well, I had to dig out my Talkpod A36 Plus cable, the FTDI cables don't work with this radio, but I did get it connected to the CPS and programmed a few analogue channels into it. It hit the 3 repeaters on the White Tanks(about 16 miles as the crow flies)and I made a contact on the Del Web repeater, all be it my TX was weak. This I'd only a 5 watt radio and we have a pretty bad storm moving through so that might be part of it. My 10 watt AR-5RM gets out very clear so the extra power does seem to make a difference. Next step is to add some digital channels to zone 2. I'll need to look them up to see which ones I'm going to want. I've watched some videos that mention adding a Disconnect channel(4000 iirc)and a Parrot (9000?)then the other channels like a World Wide and some local channels. I'll get it figured out. If adding the digital channels is about the same as the analogue ones then it shouldn't be too much trouble. Anyway, just wanted to share.

I'm for it. I live near the Van Buren/ Bledsoe line close to Fall Creek Falls.

I don’t think I provided any kind of interpretation. All I think I did is provide citations from official government websites.

Almost never.

Does the 5 watt less really make a difference between the 20G Vs the 25G?
