Emergency portable local radio communication

[Poppy]

When the cell towers are out, I would like to communicate with friends and family within a five to ten mile radius reliably (within hilly territory) and perhaps up to fifty miles away. I would like to be able to limit the distance so as not to hear conversations hundreds of miles away.

It would be good to hear the local police and maybe, be able to communicate with them.

Recommendations?

Ham radio or satellite phones. If it's hilly territory, you're going to need to rely on a Ham repeater and/or a rooftop antenna or tower.

It does not really matter ham, gmrs or frs, or cb, range is all about wattage. repeaters are nice if you can connect to them, or even have them where you are.
hills are not an issue if both are on the same side of the hill, if a hill is between them pretty much no band is getting thru, then you must have a repeater.
Sat phones are the best if you willing to pay service plans which are not cheap.

Note that anything with more reliable range than a couple miles is going to require an FCC license in the US. For the unlicensed bands, CB is going to get you the longest range (especially around hills), followed by MURS, followed by FRS. The 900Mhz ISM band radios (Motorola DTR series) are a bit better than FRS for line-of-sight communication, but I suspect will fare less well in hilly terrain.

You won't be able to legally transmit on the frequencies your local emergency responders use, at least not without their express permission, and your ability to monitor the channels will depend on the age of the radio system they are using. Many newer radio systems encrypt the communications, but older ones can usually be monitored as long as you know the frequencies.

Garmin InReach? Cheaper than a satphone, uses Iridium satellites and works well. But no voice communication, only messaging. Works really well from my experience.

Gmrs license is like a fishing license, you buy it, no tests, it covers your entire family, and costs about 70 bucks for 10 years iirc.
Ham license requires a test, like drivers permit, but study materials are available free online, for someone who knows electricity, and possesses common sense it is piece of cake, and you can do it over the zoom. iirc it is also under 100 bucks, you get your callsign after the test, which you are able to change after like a custom license plate.
In case of real emergency you can use any bands with no license. you may be able to talk to police in such case if they use simple analog radios, and their system does not require specials signal, aka tone to transmit, otherwise they wont hear you, if they use digital radios, you are out of luck.

Interesting information!
There are other satellite emergency devices available, with the ability to begin and end subscriptions pretty simply I understand. It would be great to hear from members regarding actual use. How effective is texting?

You will need a scanner to hear the Police. Check this website https://www.radioreference.com/db/ to find out if the police in your area are using encryption. If they are - you will never hear them. If they are digital, and this is very likely. They are probably using P25 digital encoding. Very few scanners do a good job of handling P25 simulcast, Uniden SDS100 will ($650). The website DB will tell you about simulcast in the area of interest.

You should not even try to talk on the Police frequencies. No good will come from it.

GMRS with good radios and antennas is my suggestion. You are not going to have to worry about hearing other stations 100s of miles away.

Oh, upon further thought, not sure those satellite emergency communicators suit your scenario. I know so little about them but thinking they are not able to text with another satellite device. Additionally, the satellite receiver that interfaces with others requires electricity, so if the area where the receiver loses power, satellite is useless.

I had a satellite radio years ago, limited utility because of complications with the service.

 

[alpg88]

aren't those satellite devices talk directly to a satellite? If they need a relay station wouldn't it defeat the entire purpose?

Emergency device sends signal to satellite. Satellite sends signal to ground receiver. Ground receiver connects with communication network. Ground receiver requires electricity to function. This is my understanding.

This is correct. Having said that, a satellite ground station that handles any important traffic will have a UPS/generator backup system.

You can text directly from one Garmin InReach to another one. It doesn't use any ground infrastructure. Grab a solar panel and you're safe in terms of battery. It's reliable and allows for suspension of subscription if not used. Bear in mind it's not like regular texting - there are delays since device checks for messages every X minutes (it's not connected to the satellite continuously).

Yes, the total wattage out makes a difference but the frequency and antenna configurations matter just as much. This is why a 1200 watt microwave oven run with the door open would barely be detectable down the street, but a 50 watt HF radio can be heard around the world.

Also, about the hill in the way: with the right antenna setup, the sky itself can be your repeater: see NVIS radio.

Well, all things being equal, power is what gives you range, Yes i'm aware of skyway propagation, but it is not possible with portable radio, it has neither enough power, nor large enough antenna. portables are usually 2-5Watts,with some up to 25watts

Best emergency radio is , imo, ham radio, it can be tuned to wide range of frequencies, unlike frs, gmrs, cb which have 20+ channels with set frequencies, ham radio is basically a scanner that transmits. the only downside is you need a license, but only to transmit, to own and listen you do not need one. My cheap uv-5r picks up all my local services pd, fd, ambulance, noaa....... pretty much anything in range i can pick up. including all walkie talkie channels.

Poppy- Where you are located most if not all police will be encrypted or trunked. Local municipal agencies (DPW, etc.) may still be using frequencies you can pick up with a scanner or handheld with a decent antenna. Communicating WITH any of the local agencies will be ill advised under any circumstances. Nothimg handheld will accomplish what you're trying to do even within the 5-10 mile range without repeater infrastructure. Take a look at the BivyStik, it's a satellite device that uses your smartphone to send and recieve text messages like the Garmin InReach, above. All things considered, probably the cheapest, easiest to use solution to your query.

Emergency SOS via satellite available today on iPhone 14 lineup

Apple’s groundbreaking safety service Emergency SOS via satellite becomes available to customers in the US and Canada starting today.

www.apple.com

apple offers emergency sos for two years from November 15, 2022 for free.
perhaps in the future they will allow seamless satellite texting when cell towers are down.

 

[scout24]

So, that allows text with 911, and just allows pings with other users (who also need a $1000 phone) with your location? Genuinely curious, not bashing.
