My next DMR radio will be one of the radios that the Blind Hams version of Open GD-77 targets. A blind/deaf ham friend of mine is interested in the Tytera MD-UV380. He uses implants to hear his radio, so audio hints help him be independent, but on his way to independence maybe I can help by learning the software.

Okay: https://www.ecfr.gov/current/title-47

That works. Thanks.

But since you asked to be pointed, here are the GMRS rules: https://www.ecfr.gov/current/title-47/chapter-I/subchapter-D/part-95/subpart-E

You’re right. I don’t care. But that link doesn’t work on my iPad anyway.

No problem! Merry Christmas!

No, because the offset is always 5 MHz and most type 95e certified radios have preprogrammed repeater channels, there’s little need to specify both frequencies.

They do. If you look at the repeater pages you’ll find that they all receive in the 467 MHz main channels and transmit in full duplex on the corresponding 462 MHz main channels. Why do you think that they don’t?

Merry Christmas!!!

As others have pointed out GMRS is most frequently used between two or more people who know each other, but there’s nothing wrong with joining in a net or even transmitting on an unused channel hoping to make contact with other GMRS users. You could set your radio to scan the main 462 MHz channels to see if you receive any repeater traffic (repeaters transmit on the main 462 channels but the channels are shared with simplex users as well.) Welcome to the forums and Merry Christmas!

Yes, there is a driver that is compatible with W11. It might even be the one that works for W10. There were some problems when MS changed their driver model but by now the larger companies have caught up. Be sure you install the factory driver before plugging in your cable because otherwise Windows will attempt to install a driver that might or might not work.

Yes, sorry, I did mean Talkaround. I understood it as exchanging the Tx and RX frequencies. I could be mistaken. post script- I was wrong. I was thinking of Reverse.

You could be right but talkabout is a function that reverses the transmit and receive frequencies normally used to communicate through a repeater. That’s why I interpreted it as I did. Unless the OP says something we might not know what was meant.

Transmitting on the 467 MHz main channels is only allowed by the regulations to communicate through a repeater or for testing (or between two Fixed Stations), so if you mean for one person to be transmitting on a 467 main channel directly to another person who is then responding on the matching 462 main channel, it would technically only be allowed while testing, not as a full time communications mode. Or did I miss your point?

Perhaps bonding the body parts of your vehicle will help. Some people do it. I haven’t, but I don’t seem to have the same problem. http://www.k0bg.com/bonding.html

Here’s a pretty good document that describes what the National Electrical Code requires: https://reeve.com/Documents/Articles Papers/Reeve_AntennaSystemGroundingRequirements.pdf

So how did the static suppressors work on the masts and antennas on the ship and why wouldn’t that work on land? A direct strike to your antenna probably would be a very bad day, but a properly grounded gas tube surge suppressor near your entry point, as well as other measures, such as single point grounding of devices that are connected along the coax, adequately grounding your tower, and placing lightning rods higher on your tower than your antenna, can help prevent a direct strike in the first place. Before lightning strikes, a static charge often begins building up. A gas tube surge arrester can help avert the conditions that can lead to a “direct strike” by allowing that static electricity to dissipate more easily to ground rather than building up. I suspect the static suppression on-ship worked similarly. No single measure is perfect, but many thousands of professionally designed repeater installations survive storms annually (and some die). Of course you folks in Hamilton never get storms, right? Welcome to the forum! Steve, in Butte, where gallows frames serve as lightning rods.

Now that Raspberry Pi board’s are easier to obtain, maybe the node that’s sold on this site will become available. Someone has already done the difficult coding and there are several threads in these forums that discuss the configuration settings: https://shop.mygmrs.com/collections/repeaters-and-accessories/products/repeater-linking-bundle I understand that’s not what you’re interested in doing. I only mention it so you know what’s available. I wish you well in your endeavor.

A DigiRig is just a second sound card plus an interface for CAT control on radios that support it or PTT control for radios that don’t have CAT control. You could probably connect to your audio in and out from your computer but Zello needs PTT I would assume (I’m not knowledgeable about Zello). The thing is that you’re trying to reinvent a bunch of stuff that folks have already done using raspberry pi and pi hat sound cards. I think that’s wonderful; I love people who want to make things, but it’s definitely not an easy path.

We’re with you! Merry Christmas!

Do you have a duplexer? I have a Digirig. They’re very nice, but they require connections to the mic and speaker jacks, which will already be connected to your other radio for use as a repeater. Also, I don’t know how you intend to bridge from the repeater through the DigiRig, to the internet. Will you be dedicating a Pi to talk to the Digirig and serve as the Zello node?

You’re overthinking it. Just say the four letters and three numbers together. In time you may find that you like the uniqueness of your call sign.

This one is in the shopping area of this website. It’s capable of being mast mounted and durable enough for mobile use. https://shop.mygmrs.com/collections/antennas/products/nagoya-nmo-200c-dual-band-nmo-antenna There are several mounts there as well, including bracket style mounts for your mirror or ladder. Here is a mount that might work: https://shop.mygmrs.com/collections/antennas/products/nagoya-rb-100n-nmo-drill-and-bracket-mount-kit

We’re all capable of making comments that are baffling in retrospect. Don’t beat yourself up about it. You seem like an honest and humble person which is much more important than being a smart-ass.
