r/gmrs

The TidRadio TD-H9 a GMRS radioclaims to offer ARPS, but this seems impossible. How does APRS which uses only 144.390 MHz in North America work on GMRS which uses only 462 & 467 MHz?

Update: I didn’t expect this much interaction! A couple of things to please keep in mind:
(a) I’m just a regular guy, dad, husband. I’m paying for this out of my own pocket, with the understanding that things get lost damaged broken and forgotten about.
(b) 5w radios do just fine on the rides that we do, and if someone needed an accessibility device, we would likely put them immediately behind one of the guides for secondary safety
(C) I want to be able to throw these in a harbor freight pelican, and know they’re there when I need them. For this reason, has to be a hand held mobile radio and not a mounted device.
(D) thank you all again. I’m just a guy who saw a need. Our group is over 25k in our state, we frequently ride, and I see this as an opportunity to to be more inclusive in our events

Hey Yall,

I’m part of an off-roading group that primarily uses GMRS radios for communication on the trail.

We recently had an event and one of the attendees has a disability requiring them to use a cochlear implant.

As someone who believes that off roading is for EVERYONE and that EVERYONE should be INCLUDED — I was really disappointed with myself for not being prepared.

I was speaking with a friend of mine who wears a cochlear implant and she let me know that as a deaf person she runs into this all the time — but that things are getting better with Bluetooth connectivity. She explained to me that most hearing disabled individuals use either a cochlear implant or a hearing aid — almost all of which are Bluetooth enabled.

This has now chased me down a rabbit hole and I need help:

I want to get 4 decent handheld radios with Bluetooth connectivity for the express purpose of being available for the hearing disabled.

Unfortunately, the options are pretty slim between Retevis and some others. A quick search of Midlands website has me thinking they don’t have BT on their handhelds at all.

Help, please. I want to do the right thing here for our organization where we can be prepared and never find ourselves in a position of not being able to accommodate

I have been using this radio for about a month now. Love it!

My question is about the compass. I am not sure/clear how to use it. How am I supposed to read it?

It is calibrated. When I turn around, the compass doesn't work to give me the correct direction.

What am I missing???

I enjoy talking on my radios (HAM) while I am on long raod trips, and though I would throw a GRMS radio into the mix, so I got license and picked up a mobile GRMS radios. And wondering is there a channel the would be good for road trips (such as on ham radio on 2m and 440 we have the national calling freq)

Asked in the chevy subs as well with no reply.

I have a 2025 Chevy Equinox regular not EV or Hybrid.

I asked the service guy if I could install a ham or gmrs radio, he said no. The electric system won't allow for it, even strait to the battery. The system cant handle the load.

I emailed chevy, nothing.

Can't find any documents or install advice anywhere.

Thought about putting a Jackery type battery in the back and running off that and charging it via a cigarette outlet.

Thoughts?

I have a mobile GMRS radio, and every so often, usually early in the morning, I'll turn it on and it'll act like it's in monitor mode - every channel will break squelch even if there's nothing transmitting, and the RX meter will show 2/9 on most channels. From what I can see, it otherwise receives signals just fine.

I can up the squelch and that helps, but I find it's very sensitive and that starts to cut out actual transmissions as well as repeater squelch tails.

Another thing - when this happens, usually a few hours later by late morning it clears up and the radio behaves normally.

I'm most worried about whether there is moisture in the NMO housing or getting into the RG58 cable causing a short of some kind. But I don't know how a shorted antenna behaves, what should I expect in that situation?

Is there anything else I can try?

Hello, I was on an overlanding trip recently, and some of the vehicles had FRS radios, and some had GMRS (myself). According to the frequency charts, both radios should be able to share channels 1-22. We used channel 1. I could hear everyone on the FRS radios crystal clear, but they could not hear my GMRS transmissions at all. Like I wasn't even transmitting. I tried that radio with another GMRS on channel 1 when I got home, and it was indeed transmitting, and I could hear each radio on the other at home. Does anyone have any idea why I would be able to hear the FRS operators, but not the other way around? Thanks!

Does the fcc really care if I transmit on gmrs frequencies and repeater frequencies without a license ,if all I do is just press the PTT button and say nothing?

Hello, I am fairly new to the hobby and ive been doing some research but i figured id ask here. am i legally allowed to listen (not transmit) to the Noaa weather stations. My gmrs is a Wouxun KG-935G Plus GMRS, i got it mainly to keep up with weather and radio transmissions in emergencies or to keep a eye on barometric pressure while fishing

I recently got my GMRS license and was reading the FCC rules and it says that your antenna can not be removable, and that your radio has to only be able to transmit on the specific frequencies listed in the GMRS section, so if I can program the radio with any channels I want does that mean It doesn't qualify for GMRS or if I make those channels RX only then does it qualify?

As far as the antenna situation, the ones I see on amazon don't have an integral antenna most screw on, and can be changed for a longer one, are those alright and can I use an external mag mount antenna in the car to get better signal from other cars that are with me?

A few days ago I lent my sister an HT to try and see if we could connect via a repeater. She lives about 75 miles away as the crow flies. There's a repeater on the Promontory peninsula in the Great Salt Lake and I was able to contact her tonight via that repeater. This repeater thing is magical! I remember as a little kid having walkie talkies that only worked a mile or two and these little things could hit all 3 counties away!

I'm building a 50w GMRS pack radio and wanted to see if a 6dB mobile antenna could be packed with it. Are there any 6dB mobile antennas that are TNC or can be converted from NMO to TNC? I kinda don't want to deal with NMO for a pack radio and most of the pack radio kit available are smaller connectors. Can I just unscrew the top antenna from most NMO connectors?

What is the process like of a GMRS license on the FCC website?

I recently bought a radio for scanning GMRS repeaters running from a local shopping center. The Hooters restaurant in the shopping center has a repeater turned so loud. I can hear it from miles away. The restaurant announced when their female staff has to be walked out back and customer credit card information all over the radio.

From a business perspective, internet-based push to talk systems using cell phones would be far more secure. We have done so much work with this over the years with data management that radios are the weak link for business communication.
