Elevation relative to sea level is irrelevant. AGL is relevant. Just express things relative to each other.

It’s one choice. There are others and without a basic familiarity with your situation I would not make a recommendation. What exactly are you trying to do?

Any tunable GMRS antennas will work as long as you have enough distance between them. Vertical separation requires less distance. A duplexer is easier, but has its own disadvantages. Tune the transmit antenna to 462.xxx and the receive antenna to 467.xxx where both frequencies are from the appropriate Main frequencies.

Are these for GMRS? Do you have an experimental license that allows you to do DMR on GMRS? What channels do you want to use? What is it that you’re having problems with? What have you tried, what do you hope to achieve, and what experience do you have? More questions will almost certainly arise; you gave us very little information to start with.

The radio plus repeater setup in the pictures is not GMRS and will not support GMRS radios.

There are steel disks that are peel and stick on one side to attach to your roof. Then you just stick the magnet to it.

This^^^ I’m an admin on three Facebook groups, including one with 10,000 members. It’s a thankless job except for the really nice people, which fortunately is most of them. This forum is remarkably well behaved. Sometimes a person gets impatient or drunk posts and makes an idiot of themselves, but for the most part we all get along even though we may disagree.

Relax, forums are meant for conversations and sometimes conversations meander, especially when the original subject has been exhausted. Calling people idiots almost never works. Of course, neither does telling someone to relax.

I agree, but it’s a different situation. HK went from being a British colony to being basically given to the PRC by the British. Taiwan has considered itself the rightful government of China (Republic of China) since 1947, and thus part of China. The PRC considers Taiwan as being part of China also, but obviously disagrees about whether they’re the rightful government. The United States has implicitly (and occasionally explicitly) stated that they would protect Taiwan from PRC aggression. Nobody except Taiwan is in a position to negotiate away Taiwan’s independence, but a change in philosophy by an incoming U.S. president could signal less commitment to protecting them which would result in a takeover by the PRC. I worked in Taiwan and grew to love the people there. I would hate to see them betrayed by our government.

Garmin is made in Taiwan. At least the one I have is. China might think it has a claim to Taiwan, but at least right now they’re separate politically and philosophically.

I used to use Tapatalk for the too many forums I belong to, gun forums, rocket forums, programming forums, and radio forums, but one of the forums discontinued Tapatalk support and I changed to using Safari. It seemed to work better and allowed me to access everything on all the other forums so when I replaced my phone and iPad I just never loaded Tapatalk. I’ve never missed it. There were a few things I just couldn’t see in Tapatalk, maybe related to sigs. But Tapatalk was fast and a fairly thin client that worked well when the phone I had had less memory. I have nothing against it; I just moved away from it.

I wouldn’t let power lines prevent me from putting up an antenna on a mast. There’s a huge separation between 60 Hz and 462 MHz. Trees are a challenge, depending on the density, height, and moisture content, but you still shouldn’t assume defeat.

Sub channels are a misnomer. There are only 30 channels in GMRS. Subchannels refer to a tone or digital code which is used to tell a radio when to ignore transmissions and it’s just another name for CTCSS, PL, etc. Every repeater will have a CTCSS tone or a DCS tone on the input, which your transmit tone MUST match or the repeater will ignore your transmission. However, the tone mode is less limited. Right now you say Chirp shows you’re set to TSQL. That means your radio will only break squelch if that particular tone is received. If you set that to TONE, instead of TSQL, it will still send the tone you program, but it will allow anything through. That’s especially helpful when you’re getting started so you can hear someone tell you you’re using the wrong tone.

Wow, what an ignorant, dismissive, and biased comment. Blind people read, probably better than you. They overcome their disability much more gracefully than you seem to travel through life. My friend Maurice is a deaf and blind ham. He has a braille reader that reads the text from his screen and presents him with a braille representation of each character. He also uses an application called Voiceover that speaks text from his screen to his hearing aids. The OP said that his screen reader was unable to process the picture that Randy posted so we know he has a screen reader. Once again you’ve demonstrated your lack of reading comprehension and made yourself look like a complete jerk.

No, you do not need to load the Tapatalk app. Randy, one of the regulars here, reacted to your question about legality by posting a gif showing Michael Jackson eating popcorn with a caption that says, “I’m just here to read the comments.” Of course he didn’t realize you were blind when he posted it. Several of us, including me, reacted to his gif by clicking on the “laugh” reaction. The question of whether repeaters may be linked through Zello or other internet links is a hotly contested question that has resulted in entrenched positions and some hurt feelings. There are several other threads discussing whether linking is allowed by the regulations or not. Unfortunately, your question is unlikely to receive an authoritative answer. Many repeaters are linked and the FCC hasn’t taken official action against them, but the FCC does have a statement on their website saying that GMRS repeaters may not be connected to networks, even though some of us dispute that the regulations state that. So, I don’t have an answer for you, but I hope the background information will help you make your own decision.

I just read through the manual. On some radios, you set the Tone Mode to TONE instead of TSQL, it doesn’t expect or use the Rx DCS. On your radio, that’s set with menu 29, SPK. When SPK is set to SQ, it doesn’t require a code or tone to receive. It reproduces all signals it receives on the RX frequency. Unfortunately, your radio doesn’t appear to allow different codes for TX and RX DCS. For the 9800, if you’re set for DCS it expects both transmit and receive DCS codes to either be the same code or inverted versions of each other. You didn’t say what the two DCS codes are. So, try setting menu #7 DCS.COD to the tx code, menu #8 to match the normal or inverted value needed, #29 SPK to SQ, and #23 RF SQL to a squelch level that you can live with, since your radio won’t be breaking squelch based on a received DCS Code. If that doesn’t work for you, then you may have to use one side of the radio to transmit using one DCS code and the other receiver to receive using a different DCS code. Sorry if this doesn’t work.

Set it to TONE, not TSQL, and it will transmit using a tone and receive anything regardless of the tone.

My favorite Garmin GMRS radio has a setting to enable the repeater channels. When the setting is on, no digital data (GPS location and text messages) are sent.

I’ve reported your distress call to Rich. He’s usually very good at responding but he is just one person.

It’s the same radio as the TYT MD-UV380. I bought one of those and installed openuv380 on it, which replaced the factory firmware and made DMR much easier to use and program. OpenUV380 also supports several levels of speech. Once I made those changes I sent it to my blind friend to use at the National Federation of the Blind Deaf/Blind convention in Orlando earlier this month. He’s going to send it back along with one other for me to load the same firmware. It worked so well that I thought I might get another. If you get one and send it to me I’ll do the same for you.

I might pick up a Retevis RT3S, like this, with GPS: https://www.retevis.com/rt3s-radio-cable-longantenna-sparebattery-bundle-us

None of us do, but knowing that is the way to learn.

You seem to be projecting. That’s a bad way to start a week. I hope whatever it is gets better for you.

Go through the manual and set everything that has a timer or reset time to off or zero. https://tidodmaster.oss-us-west-1.aliyuncs.com/h3/H3-Ham manual.pdf

Welcome! What are you trying to set it up to do? I don’t have one but others do and will need to know more about your goals.
