Magnetic Antenna Mounts and Paint Damage
SteveShannon replied to Over2U's question in Technical Discussion
That protects the base of the mount, but isn’t effective at protecting your paint. The vinyl will still move against the car’s painted surface, maybe even easier than the rubber. Iron dust (which is everywhere because 5% of the earth’s crust is iron) will be attracted to the magnet through the vinyl and can become embedded into the vinyl where it will abrade the paint. If the vinyl is stuck to the paint then it becomes the sacrificial surface that the mount grinds against. -
If they used their call sign as their ID, or if they’ve included it in a post you can find it with a search. It’s possible that they have a sign-in for the website but not for the forum. But, if you know their call sign it is very easy to look up their name and address using the call sign lookup on the website here or in the FCC database. What’s the call sign?

I bought the NanoVnA from R and L electronics. It is well built and has N connectors rather than SMA. Used with nano Vna saver software it’s a piece of cake to use. But it’s not my favorite. I’ve worked on an MFJ 269D analyzer. They’re poorly built and I would never buy one. Now I have two different RigExpert analyzers. I really like them. They are my favorites.

Radiodiddity UV 5X/ Baofeng UV 5G
SteveShannon replied to WSAH452's question in Technical Discussion
No, doubling the power won’t double the range. You might be surprised but doubling the power might not make any real difference in range. Power isn’t the limiting factor. -
Almost no antennas truly transmit on the one (and only one) frequency where they are resonant, yet they transmit well enough. Although that’s an MFJ SWR meter and the numeric value might be incorrect, it still will show you where the SWR is the lowest, so I wouldn’t worry too much about that. Like WSAM454, I absolutely would suspect that the frequency you are transmitting is the 462.xxx MHz frequency instead of the 467.xxx MHz frequency. I’m sure you set it right in software, but radios sometimes try to outthink us. Try using one of the factory repeater channels (23-30) with the correct CTCSS or DCS tone.

From the Guest forum introduction: Note to Guest Users: To participate in all Forum threads, you must be registered at the main MyGMRS.com website listed below. In order to register at the main website, you must have a valid FCC issued GMRS license and call sign. It can sometimes take up to a week for the FCC database to sync with the MyGMRS.com database, so if you try to register at the main website and get a note stating that the license listed in your application is not valid, please wait a couple days and try again. Once you are registered at the main website, THEN you can also register here at the forum. Thank you.

Did you look on the repeater page?

Would like to know what radio you are using

Custom built coax cable with connectors or pre-built?
SteveShannon replied to WSAW350's question in Technical Discussion
Instead, I suggest that you get the factory made cable with the N connectors and use the adapter on the radio end. Electrically it’s the same but having a factory N connector on the cable where it connects to the antenna will be more weatherproof. -
Filter out only one DCS code?
SteveShannon replied to kapoijerj334's question in Technical Discussion
It is feasible. The feature is called lockout. Unfortunately no retail GMRS radios that I know of have it, but scanners and some commercial radios have it. -
Radiodiddity UV 5X/ Baofeng UV 5G
SteveShannon replied to WSAH452's question in Technical Discussion
It’s impossible to reliably say. They might go from one block to another or they could go miles between upper floors of two different buildings. -
And for the record, you should never have to worry about being a bother when you’re asking questions.

Here’s a better description:

Each DMR repeater is a kind of a gateway into a network of DMR talkgroups. So a repeater connected to the Brandmeister network can be used to connect to almost every talkgroup on the Brandmeister network. So, my local DMR repeater has the Montana Chat talkgroup as its default talkgroup. But I have a bunch of channels configured that allow me to simply change channels and key up (as long as nobody is talking on the repeater at the time) and the repeater will be connected dynamically to that new talkgroup and not to its default talkgroup. Usually a repeater will eventually times out and return to the default talkgroup. I keep busy channel lockout turned on on my DMR radio so I don’t interrupt others.
-
If you get on the right talkgroup it can be busy all the time. TG 91 is worldwide English speaking and has conversations full time. But keep in mind that when you get on a DMR repeater and change talkgroups, everyone else listening to the repeater is taken to the same talkgroup. If you want to hear lots of activity and not just use the repeater locally, a hotspot is really the way to go.

He hasn’t been here since 2019.

RT System software can automatically populate repeaters in your radio’s memory based on location (zip code plus radius is just one way). Chirp has similar features. Use the memory banks or zones of many radios to create zones that reflect different locations along your journey and then just switch from bank to bank (or zone to zone) as you travel. Alinco’s DMR radio even has “roaming zones” and a built in GPS.

Here’s what their website says: WHAT IF I JUST USE AND DON’T JOIN THE SYSTEM? We won’t kick you off the System. However, we will notice if you’re on a lot and haven’t joined. You’ll probably get an email or phone call to encourage you to become a member. The PAPA System is member-supported and we depend on membership to support repeater maintenance and site rental.

Paid repeater? All ham radio clubs encourage membership and gleefully accept donations. We might have a difficult time paying for all that goes into the expenses associated with repeaters otherwise. Im not a Papa member and I certainly can’t speak for them but I suspect that if you donate what you can they’ll not mind you using the repeaters.
