- In this video I detail some of the history of PMR446 radio and its use here in Europe (for now at least) I discuss the channel allocations, power levels and if you can legally use cheap Chinese dual band radios legally as PMR radios.
I also discuss EQSO and repeater operation of these radios.
Nice informative video post Paul I found it very interesting well done mate.....
Nice one Paul, interesting video! A lot of people don't realise how useful PMR is any how you can get some awesome distance. My best walkie talkie to walkie talkie was 63 miles hilltop to hilltop
Wow 63 miles that's stunning! When I tested the floureon the other night I don't think propagation was very good I might take them back when things improve and try again because in theory Line of Sight 6 miles should have been ok
How many watts was this walkie talkie and what antenna was used.
Most will agree that 63 miles is unlikely for any walkie talkie no matter the band its on
FRS radios in the U.S. are now authorized for 0.5 W and 2 Watts. However, the 2 W side is only available on certain channels.
Thanks for this information :-)
You are welcome.
No one FRS radios with 2 Watts - like as Motorola.
Btw. There are now some PMR versions of Chinese handhelds. Like the Baofeng BF88E which is a version of the BF888. There is also a PMR version of the Radioddity R2. They both come with fixed antennas and 0,5W output.
The new standard allows for removable antennas.
One way to extend range is to transmit with your legal PMR radio and receive on a scanner or a more sensitive ham radio with a high gain omni or a yagi mounted as high as possible. A magnetic mount mobile antenna would also work well in the car. You would need listen with headphones to the receiver to avoid feedback.
That's a good idea 👍👍
Same law here in Belgium with 0,5 w 16ch, but in Belgium repeaters, base stations and in car radio's are not allowed only portable sets in PMR446, cb radio is licens free and only 4W 40 channels am & fm mobile base or portable and only 2W for SSB
Thanks for this information 😎
The history of the 27MC
The 27MC tire became popular among American truck drivers in the 1950s. The "bakkies" were used for mutual communication and thus broke the grind of the long, mind-numbing journeys, but they could also help each other in the event of a breakdown. At that time, the use of these transmitters was illegal in the Netherlands. This did not change until March 3, 1980. It was allowed to work with 0.5 watts in FM and on 22 channels, provided they had a license (MARC license). This cost 35 guilders and could be bought by anyone without a course or training provided you were 14 years or older. It became an immensely popular hobby and within a short time there was also a huge crowd and it was almost impossible to cover long distances at normal times. Partly because of this pressure, 40 channels were later (in 1982) allowed with a maximum power of 2 watts to eventually reach the current CEPT standard of 40 channels with 4 watts on FM / AM / SSB.
Great explanation although I have to say, the image of the London skyline 0:39 is a true blot on the Landscape.
I guess Im asking the wrong place but does any of you know of a tool to get back into an Instagram account..?
I was stupid lost my login password. I appreciate any help you can offer me
@Colten Troy Instablaster ;)
@Archie Brock I really appreciate your reply. I found the site through google and Im trying it out atm.
Looks like it's gonna take a while so I will get back to you later when my account password hopefully is recovered.
@Archie Brock It worked and I actually got access to my account again. Im so happy:D
Thank you so much you saved my ass !
@Colten Troy Happy to help :D
Great info
Very nice video! I bouhgt 2 baofeng BF T-1 allready programed them, but they only communicate with each other with in 100 meters, but they communicate with a repeater 3 km away!! Theres something missing here! Can you help me please? Thank you it will be much apreciate it.
I have a BT_t1 and its TX and rx is fine. I did read some where that the antenna can suffer dry joint on the PCB.. so may be worth checking.. I have also done the audio mod so they no longer deafen you even at the lowest volume setting. Have you tried using other radios to see if it just one of your radios that is deaf or has poor transmit.
Another great informative video buddy but reminds me I did bring 2 talkies home from Florida in 2008 so wonder what they operate on ?
But in the flip side the world needs a standard so everyone don't interfere if the skip is up etc what u think?
Yes if they were FRS radios then you might want to check them Paul, thanks for the comments :-)
FRS was increased from 500 milliwatts to 2 watts in 2021.
Please can you tell me which is better walkie to use it with my family on ship cruise the most powerful and good battery life thank you I just thought about k wln what do you think about it
So how do repeaters work with PMR446?? Is it legal???
Hallo Gruppe, könnten Sie mir einen PMR Funkgerät empfehlen, das ich mit ohne Lizens nutzen kann /darf?
Danke!
How about cb on the old uhf police band there's 99 chns free 5 watts great
that control center/room at @ 2:56 :O ..
WALKIE TALKIE HAS LONG RANGE INPRESSED FOR 0.5 WATT
EVERYONE SHOULD HAVE ONE AS "BACKPU" NEIGHBOUR HOOD WATCH OR PET OR BABY WATCH OR " SECURITY " .
My best Is 26 miles :D
That's flipping amazing!
knoxieman he meant when he did London marathon. Lol
How about Chinese 409 MHz 20 channel radio in North America, Australia and Europe??
Not legal sadly
What happen if you use pmr446 on a baofeng uv-R5?? What's or where is the problem exactly??
There isn't one other than its not legal to do so in most countries because of the power output, even in low power the UV5R is too powerful to legally operate on PMR, that being said everyone does it to be honest.
I'm wondering if a Baofeng etc should be on wide or narrow mode.
Wide
NARROW
So just so I'm clear, You can NOT use DMR radio for GMRS, Right?
That's right you can't
That is what I thought, Thank you for your reply.
Can I legally use PMR radios In the USA and Canada if I am a licensed amateur operator in Canada?
No not legally but if you are careful and stick with low power PMR sets you won't have an issue, I hear FRS sets in the UK all the time.
Why are old a 25khz PMR soundig so much better (sounds louder) then the 12.5khz mordern pmr radio`s?
Wider bandwidth equals better audio quality narrow bandwidth equals less space for audio signal hence worse quality, that's why FM radio music stations are wide band.
Oke, so if I want a PMR radio, it`s better to buy a older 1 generation PMR radio due to the larger 25khz bandwidth?
Vic Green no. You will hardly notice difference unless you are a teenager
In sweden 446 mhz wee have dis radio in sweden for PMR 446 mhz
Do you have users in your country transmit on PMR with more than .5 watts?
Yes
Same here in the USA. MURS and FRS are being overrun by cheap Chinese radios pushing out exponentially more than the law allows. Thankfully I have amateur radio.
Not sure many people stick to the 0.5 watt rule here in the UK. Most users are using a baofeng uv-5r to transmit which can go up to 5 watts on high power. You can even get baofeng models that can reach 10 watts now for quite cheep, so I think the y0.5 watt rule has gone out the window for most PMR users.
In sweden are diss mhz 446 mhz
Fire in UK don't use analogue anymore
I think I sent you the channels on another thread somewhere on TH-cam each channel number and colour code for 1 to 8 which is simple as cc is also 1 to 8 tgid across uk is 901, but expect training centres to be differant and also some may have a freq channels extra with a differant tone but sane freq as u can add to national plan not take away from it though
0,5 /500 a half watt ;)
Great video! 73 de E73HAK
Thanks
Honestly! The monotone delivery of this video eventually caused me to lose the will to live. I just gave up!
I was quite poorly when I made this video
