Great to see another video on these excellent amazingly low priced radios. As you know, I have no problems getting into the GB3GR repeater in Grantham from Mansfield using one of these, and am also able to do that using my BF-T1. From the date stamp, I see you are time travellers too. 😜 73 M7TUD
It's Amazing How The Chinese Can Produce Them Radios At The Price They Do I've Got A Little Baofeng UV 5R III It Really Is A Cracking Little Set Pushing Around 4 Watts Great Video Lads Bless Up
SDR and power mosfet's mean no expensive ceramic or crystal filters, nothing to manually tune, wide band front end and TX PA, and easy to mass produce. but it does mean very poor strong signal rejection, Most Private Business Radios are still Superhet as they have to work under all strong nearby signal condtions
And they’re not a bad little 70 cm radio for FM repeaters and a simplex a bit more power up to sort of the 4/5w would be nice but for the money you can’t really complain they’re good radio 73 Tom VK3FTOM
Yes, I am the sole owner of the repeater & personally pay the site rental & electricity bills at the commercial 2-way radio site where it lives. Richard, G0OJF, UK
Sad to say that for security reasons, no photographs are to be taken at the commercial 2-way radio site where the repeater lives. If I recall, the license power limit is about 12W. In order to try & not suffer from pirates or wallies, there are no 'courtesy tones'. The repeater comprises of all-new equipment about 3 years ago & is a commercial talk-through base station, PSU & aerial filters each in 19" racks & the aerial is a Diamond product manufactured specifically for repeater use. It is single antenna working. In line with license requirements, the repeater sends it's callsign in morse every fifteen minutes. Richard
@@ukfmcbradioservicingTango21 Yes i under stand for security reasons,12 W is perfect as it shows when you and MR C have used it with hand portable radios.Yes i get fools on the 70cm and 2 meter repeaters where i live it is a pain at times. Chris
Bit much for 70cms without the repeater. Well done on the demo. You need line of sight or height. I agree on the cost of radio, why should it cost thousands. No fun in that! A cheap radio like that will put you on air on the Foundation Licence.
Yes, as I mentioned in the video; a gentleman in Sheffield sometimes joins us on GB3GR on our 8PM Wednesday night net using one...and that's a good 65 miles to the repeater. Yes, it's plugged into his roof aerial, but is still less than 2W. Richard, G0OJF, UK
The aerial that comes with them is poor, a later series UV5R aerial works better and thats a dualband. i use 17cm Kenwood TK3107 PBR 1/4 wave, a 16inch 5/8th would be ideal but a commerical one would cost more than the radio
Yeah, of course it's not 10W. It's more bullshit than VW car spec figures! The US goverment determined that the absolute safe power limit for UHF handhelds is 7W, so it's best to have them 5W & under. I've been in commercial 2-way radio for 4 decades & have yet to see UHF handhelds over 5W. I would always ensure UHF radios are 5W or under before returning them to customers. Richard, G0OJF, UK
@@ukfmcbradioservicingTango21 depends on the field strength? 10w into a 16inch 5/8 might spread a wider lower field strength to your head than 5w into a short helical?
You have to program it for frequencies you are licenced to use. It would be illegal to use on PMR446 freqencies for example. So we programmed it for 70cms amateur radio channels for which we are both licenced. Richard, G0OJF, UK
The slim jim is effectivelt a folded dipole so has no gain or loss & is a great aerial for people who have little space. Here at the base end I'm using a 'white stick' colinear base station aerial which is 3 x 5/8 wave stacked with quarter wave groundplane radials. Bear in mind I'm in the middle of nowhere with an acre of garden & no neighbours for 1/2 mile. Richard, G0OJF, UK
@@ukfmcbradioservicingTango21 I am sorry but I got one working on 88 to 108Mhz and really pulls in stations very effectively I would be making another for 174-239Mhz some time.
