Thanks ? Both MURS and FRS prohibit store and forward. That might be what you remembered.

I do something very similar on ham 70 cm, using DMR. You can either transmit to a talkgroup called "Parrot" and then listen for your transmission repeated back or you can look at a dashboard and see the actual S value as you hit the repeater.

Nothing in the regulations establishes priority for simplex users or repeater users. We're all equal in the eyes of the FCC. ?

Which rule prohibits store-and-forward for GMRS? 95.587(d) prohibits it for FRS, but I don't find something similar in part E. I could easily be overlooking it.

By definition an open repeater is one that doesn't require permission, so no. Welcome to GMRS!!!

So I left my radio on listening on the analog side and I just heard the 70 cm DMR repeater ID itself. It did so in analog mode using Morse Code after the first DMR transmission in a long time.

Some repeaters do their ID without a tone. People who have a tone set for receive won’t hear it. Here’s where I first learned about it:

During our weekly nets the repeaters always break in and auto-ID. We just pause until it’s done. We understand that it’s required and I’ve never heard anyone complain about it. But that is for a repeater that’s not networked. On our DMR (ham) network, which is linked to the Brandmeister network, I don’t recall every hearing a repeater ID. I’ll have to listen on the analog side to see if it’s IDing itself there.

A person who has a repeater can link it to a network of other repeaters. Once it’s linked it’s a node on the network.

A better place to ask (or even read) is in the forum dedicated to GMRS networks. I haven’t done the process, so I can’t honestly answer your question but people who have have described.

Pi Shop also got some in today. “Hello! We have restocked a product you asked to be notified about. Please check it out before it goes out of stock again! Product Back In Stock: 1063: Raspberry Pi 3 – Model A+ (PLUS) - 512MB RAM Thank you! PiShop.us Support Team”

Tim, You're right. Someone will always be unhappy, no matter what you do. The problem is that if repeater owners are allowed to remove negative comments, every repeater will only have positive comments. Reviews will no longer have any value. You may be better leaving them in place. Many of us are capable of weeding out BS reviews from honest reviews. Steve

Being able to transmit on frequencies isn't strictly prohibited - the radio just has to be certified for the service which uses those other frequencies and for which certification is required. Also, it must not be FRS or Amateur Radio Service. Here's the portion of the regulations that addresses that: § 95.1761 GMRS transmitter certification. (C) No GMRS transmitter will be certified for use in the GMRS if it is equipped with a frequency capability not listed in § 95.1763, unless such transmitter is also certified for use in another radio service for which the frequency is authorized and for which certification is also required. No GMRS transmitter will be certified for use in the GMRS if it is equipped with the capabilities to operate in services that do not require equipment certification, such as the Amateur Radio Service. All frequency determining circuitry (including crystals) and programming controls in each GMRS transmitter must be internal to the transmitter and must not be accessible from the exterior of the transmitter operating panel or from the exterior of the transmitter enclosure.

No problem at all. Hopefully you will hear from @rdunajewski.

Almost every day this week Adafruit has released 100 Raspberry Pi model 3A+ for $25. Customers are limited to one only and you must have an Adafruit account with two factor authentication in order to buy. They appear in inventory at about 9:15 am Mountain each day. They sell out quickly and the 2 factor authentication isn’t explained well until you try to login after creating an account.

I don't know. I held off saying that yesterday. I didn't know then, but I was hoping someone who did know might answer. You deserve some kind of response.

With your permission, I can report this part of your post. That gets Rich's attention (it's not a strike against you!) and in the past he has helped others fix their usernames.

Also, consider the use case. If you’re mostly just hitting a repeater you might not need much.

You’re right, it’s case by case, but I would lean towards getting the antenna up a little higher.

It will depend entirely on the type of cable and how well your system is performing now. Every type of cable has a characteristic loss figure that is much higher at the UHF frequencies of GMRS. It’s usually specified in terms of dB loss over 100 feet and the loss is linearly proportional, so for 50 feet you would expect half that loss. Getting an antenna with some gain and getting your antenna up in the air can make up for that though. Using LMR400 you lose 3dB over 100 feet. That’s half of your output power and half of your input signal strength that you would be losing. That doesn’t mean that you cannot use it, but be aware of the limitations. So, over 50 feet, using LMR400 you would expect to lose a quarter each way. If you have a good strong signal both ways you might not notice. Switching to better cable will reduce the losses. Getting your antenna in the air will also.

Maybe that was MURS. If you can’t use the FRS channels because they’re busy, you won’t be able to use GMRS. With the exception of the repeater input channels they’re exactly the same frequencies. And you’re not allowed to use the repeater input frequencies for simplex between handhelds.

This! If people don’t know the rules they don’t have a chance of following them.

Will 2 watt MURS or FRS radios work for your purposes?

Welcome! You’re pretty fired up over a two year old post. You’ll fit right in here. ?

I agree completely and I believe that’s exactly what was intended when the FCC used the language “under the authority of the individual licensee.”
