I think you invented the "ham radio tourism" industry. I'll check out some of those sights and towers next visit I have to the UK.

Thank you so so so much! You’re too kind. I really appreciate that!

They don't work at all well in a built up area. I have the same radios. At ground level I left one at home and walked 2 minutes up the road and it already stopped working. The higher the frequency the more it is blocked by obstructions. With mostly line of sight I got a decent range. I can't remember exactly what it was now but I posted a range test video.

@@radiosification It's then worse than 400-470MHz radios. What frequency is it using, 1-2.4GHz?

@@dare-er7sw yes, much worse than 400MHz band radios for getting through obstructions. They're using 2.4GHz.

@@radiosification HaHa, 2.4GHz is WiFi territory. Too bad. There are small VHF/UHF 1-2W analog transceiver modules available, one can easily build a homebrewed walkie talkie with privacy by adding a 40KHz subcarrier and modulating the subcarrier with FM voice.

Remember… the higher.. as in legitimately higher than were used to frequencies like above 5-6ghz are blocked more by buildings. WHEN. Will people learn that lower frequencies go through buildings better lol if you want good range, get a good 900mhz model lol or a lesser used band. Those 2.4ghz antennas are near the Wi-Fi bands so you want to avoid. Same with 5 and 6. Look for odd frequency bands

I also had 4 of the Trisquare radios. They were great but I had two problems with them. First, they went through batteries quickly. The second problem was if you had three or more on the same channel, they wouldn't stay synced.

Great to hear from you Ben

When you coming back on the radio ??

@blankreganon5395 do you need a license to use?

No license is required for ISM. They are limited to 1 watt. Amateur Radio shares these frequencies on a secondary basis. If you go over the 1 watt limit, you need to have a ham license.

@@cappicturesinc.4597 I'm glad to see there is a commercial solution. Although, at that price, I'm almost thinking the interface & two radios would be cheaper.

@@oliverw.douglas285 For sure, it just seems like a lot of work.

@@cappicturesinc.4597 Since I have limited hands-on experience with these radios, I'm speaking from more of a conceptual perspective. Theoretically, they could probably be interfaced through a very basic bi-directional repeater controller, which cross-connects receive audio from one radio, to transmit audio of the other. Obviously, the audio levels would have to be set to proper levels, to avoid overdriving or clipping. Beyond that, some sort of carrier-on or active channel detection would need to be brought out of each radio, along with the PTT or Push-To-Talk, to activate the respective transmitter, at the appropriate time. I apologize if I made it overly complicated. If the necessary connections from each radio, could be brought-out, & made accessible, I think a basic repeater could be made, utilizing two separate talk groups, with two 'donor' radios for the repeater. I think it would be an interesting experiment either way. :)

@@oliverw.douglas285 Ah I see, that could defiantly work. Don't worry about it, sometimes thinks need to be explained that way :)

That’s correct

2.4 ghz will travel as far as the curve of the earth will allow, the issue you may hit is timing, they are TDMA and the increases RTT delay may cause them to stop working.

No way it would be comperable,2.4GHz is more or less los in any real distance.whereas 70MHz is "almost" like CB/28MHz,propagates really well even beyond los. And we haven't mentioned Es yet.

@@joczo97 Yep, there's a reason these frequencies are used in microwave ovens, they tend to turn to thermal energy upon contact with 'stuff'. Up to 450Mhz works ok, penetrates objects and can propagate beyond raised terrain reasonably well. 🙂

@@joczo97 "E"s are good, "E"s are good...

Those things were pretty cool for what they were. AFAIK they used plain analog modulation combined with relatively slow FHSS (both unlike these Motorolas), so listening in probably wouldn't be that hard if you know what you're doing. There's a video on YT of someone doing so using Optoelectronics gear. Still a lot harder than plain old FRS/PMR446, though.

Whenever you want mate :)

@@RingwayManchester I'm from Oldham so I'll try up on werneth low you seem to reach a few people up that way.

Drop me an email, we can get on the air sometime for a test. Ringwaymanchester@mail.com

Is that strictly line of sight, mountain to mountain top?

@@rawcado Almost, in the case of FRS radios. The higher the frequency, the less the wavelength will bend or penetrate foliage.

That range is line of sight. Any radio will do 100km or more with line of sight

@@jplacido9999 yes, just like in the video, 100mw 2km

@@darkokelava4754 if you test a regular pmr446 or FRS portable, they will do dozens and even hundreds of Km once their have perfect line of sight... Only when propagation is particularly bad the range will be less.

No more than any other wireless router would

What about it

👀

Uh-oh these are licence exempt. Come on, do your homework before posting silly comments…

@@RingwayManchester is is what happens when my uncle uses my KZfaq lol, Apologies Lewis. I SHALL CORRECT HIM. Typical G stations 🙂

Ok 👍🏻 😂

I guess it's for people to talk to each other?
