program baofeng bf888 with prm446 thru chirp

[akamyers]

I hope someone can help. I am trying to program some new Bf888 s with the PRM frequencies. I have finally got the chirp software which I can read and download new info onto the radios but when I install the PRM frequencies they will not work. I can reinstall the factory frequencies and they work fine.
I also would like them to communicate with some existing Motorola TLKR80's if poss but not essential.
If someone has a screen grab of the info to put in that would be fantastic.

Try Miklor.com, I know for sure they have the images listed, but not sure if they go through the entire set up of prm446 channels or not. Quick search of google showed they are not part certified for that radio service so that could be why there are issues as well.

PRM 'frequencies' out of range for that radio.

Pmr446 frequencies thru chirp

Thanks for responses. First off made a mistake as its pmr 446 not prm. Just wondered if I can find out all the settings required, I don't really understand all the numbers and just hoped I could get a screen grab from someone in the know! Thanks

I think one issue you may also be running in to is that PMR is very popular in Europe, but I have had my radio programmed to the channels and listing for about an hour now and have not heard one thing on them while the 70cm bands are pretty busy. I even gave it the benefit of using my aerial for 2m and 70cm and not one peep...If you get a few friends that live really close, you might have a pretty good private radio system.

PMR446 is not a legal radio service in the USA. It cannot be used here. As such, if you hear anything, they are licensed amateur operators or licensed business operators. There is no license free service in the USA on those frequencies. The frequency allocations are different. That is a strictly European service.

Additionally, the user needs to check with their governments to see if those radios are legal to be used on PMR446 in their nations.

I assume the original poster is in Europe.

How fascinating! I'd never heard of PMR446, nor of the Free Radio Network (Free Radio Network) before.

It's neat how they have set up a huge international network using RoIP software that actually mixes PRM446 and 27MHz FM portables.

It's a pity something like that hasn't any corollary here in the U.S.

It is likely highly illegal.

They actually allowed the USA Family Radio Service (FRS) at one time; however, legalities nixed that plan.

It was using the now-defunct eQSO software that was ported for that stuff. eQSO went away, due to unpopularity and allowing unlicensed users too much access. Kind of like a before-Echolink type thing.

There are some dongle-type things that plug into FRS (or whatever radio you can adapt it to) radios that can let you set up some sort of VOIP to allow you to Skype via radio.

Download from Radio to get clean image, Radio->Download
Have CHIRP auto populate PMR Freqs, Radio->Import from Stock->EU LP and PMR Channels
Disable all but PMR Frequencies in the list (last 8)
So it starts at channel 1 click the Auto button, then click Okay on the dialog
Upload to radio

It is likely highly illegal.

Here in the U.S. it would definitely be illegal. Nonetheless, there are at least two Americans currently on-line with questionable frequency choices:

444.725 FM CTC 114.8 (a 20 watt repeater no less!)

462.56250 FM DCS 664N

Of course, one could quite legally use the FRN Client in PC Only mode to connect with other folks around the world without breaking any laws, but seriously how much fun would that be? I can get on 20m phone and talk with folks who at least share some of my interests!

Europe has three license free low power UHF radio services:
PMR446 (12.5 kHz analog FM)
dPMR446 (6.25 kHz digital similar to NXDN)
DMR Teir I (12.5 kHz DMR)

The frequencies used are all part of the 70cm amateur band in North and South America and require an amateur radio license in those countries.

I am indeed in the UK.
Thanks nd5y, any idea which of those sets of frequencies I would use, is it pmr, dpmr or dmr? As for all the dtcs code, tone squelch, duplex and offset's, tune set what's it all supposed to be?

 

[akamyers]

Cheers khytsus, found that but all codes appear to be in the 433 range, I think im looking for 446?

You missed the part about: Disable all but PMR Frequencies in the list (last 8)

You would use the analog PMR446 frequenecies which are the first 8 that I posted.
Your BF888 is not capable of any of the other digital modes and is probably not legal to use on PMR446 anyway because it puts out more than 0.5 W and has a removeable antenna.

 

[akamyers]

Cheers Tom, we have applied for a licence so using these in the interim. What do all the other numbers mean, sorry to be such a newby!

 

[akamyers]

Khaytsus, Ah ha, found that bit now, thanks. Now what do all the other numbers mean? Should I touch them? Can you increase the squelch?

 

[khaytsus]

You can change squelch in software or via the radio itself, yes. If you start the radio in certain positions of the knob and a button pushed, it'll do different things. Look up instructions or read the manual, it's not too bad.

PMR446 radios can legally have removable antennas as long as ERP ≤ 0.5w

 

[nd5y]

PMR446 radios can legally have removable antennas as long as ERP ≤ 0.5w

Not according to this RA357 - PMR 446 Information Sheet

5. RADIO EQUIPMENT
PMR 446 radio equipment must be handportable, have an integral antenna, have a maximum ERP of 500 mW and be compliant with ETS 300 296.
