My quansheng K5(8) will transmit from 13mhz to 1300mhz but you are right, on 27mhz you are looking at less than 10mw output.
On 446mhz you will get 3.5w, all radios are optimised for 435mhz on the UHF band, the baofengs are the same and even my home base which will do 50w vhf and 40w on 435 does 30w on 446..
Don't delay on flashing the custom firmware, forget the expanding of the frequency range , its the vastly better firmware that is desirable, the egzumer firmware is the best .
I have to pick a bone, Dont call CTCSS privacy codes, they are nothing of the sort and offer no privacy at all, everyone can still hear you, you just Dont hear everyone else, its just a squelch control system.
From the factory they are 3.5w on 440, but some of the reflashes also adjust tx up to
just over 5w
Bought the quangsheng uv5r8 a couple of months ago, cost just under 12 quid delivered. Have run it alongside baofeng uv82's on 446 and 433 MHz and it works a treat. Can hit a repeater at about 8 miles off from my nearest high point and have had contacts up to Sheffield, Bury st Edmunds and Norfolk. Yes admittedly some of these contacts are using zello or some other black magic but as a free standing handheld it's pretty good. I'm in Rutland by the way so to be able to talk across 60 to 80 miles or more is out there. I don't quite get the net radio stuff but to be able to use a bog standard walkie and talk to guys at that distance however it works is brilliant. I have a licence but limited equipment so some of the PMR and 11m are easier to get in touch with. My wife thinks I'm a right anorak despite the fact that I played in punk/hardcore bands for 25 years and ride motorcycles. Radio is a unique and underrated hobby. And it's useful should other systems fail. Thank you for your videos and tips.
Hi Dave. LOL my wife thinks the same. Radio is a bit of an odd hobby in 2024 but it does no harm. Amazing cheap radio you bought and good to know it worked well.
Yep, i understand and if SHTF (shit hits the fan), everything goes black, then that is your only communication setup and I've used it a UV K5(8) with a Baofeng on free PMR, this time low power and it works like a charm indeed. Dunno if it exceeds the 0,5 watt limit ?
Great video.. I'm an expat living in Florida and just got 2 radios here. Best video ever. Can't wait for the updates.. Thank you..
My Quansheng can now transmit CW, APRS and SSTV. Grazy good radios. Geat video The Mod's don't have effect on the warranty, because you can always load the original firmware back into the radio.
Frid in the shed I learn lot from you about bying quality cbs radios with AM FM ssb and antennas for cb radios my friend
Frid in the shed your retevis ra 79 Quansheng had held ham radio is awesome my friend
Happy New Year Greg
Tnx for the review! I used to play with cb in the '90's and built multi element quad beam antennas reaching out 75+ miles using just 4 watts! So much fun!
Been doing deep dives on the HAM scene and wow...hooked!
This radio is tops on my list but def plan on building antennas again! Chipset on this radio unlocked allows rx/tx all over the bands!
Tnx from Virginia, USA!
Thanks for the info!
Cheer's Fred, that review really helped, I've got a clone version coming in the mail, ordered it a couple of weeks ago. I really only wanted to use it as a cheap, versatile but flashable kinda wide enough band, scanner. I was glad to hear that you gave it the thumbs up as a decent scanner in your review plus the FYI of the longer antenna to help receiving. I'm not hardcore into radio's so all this advice helps a rookie like me. I am going to steer clear of the transmit side of things as once I mod it, with the situation here, i do not want to cross over into the Dark Side in that respect. But the feature is there if the need is required down the track. Lookin' forward to the programming how-to video next! 📻 🙃 👍
I jail broke mine I'm now speaking to aliens in the vicinity of Sagittarius b😮 honest😂
Love it :-)
😂
Mine gets as far as Gallifrey.😂
Welcome to the darkside LoL, just becuase we could send over 0,5W you dont need to. I have TS T9+ and could output "8W" on PMR but just becuase I could don't means I transmitt with full power. Yes it even illegal to transmitt on Low on PMR446 but if you do it some what responsible nobody will know think anything about it
@@Dynamit008 But some do.In the PMR net I go on people are using the crt space u.They transmit on 10 watts.I doubt it will interfere with anything like hospitals or emergency services though.
I also don't have anyone at home to reply on range tests, so I've set up openrepeater OS on a raspberry pi and made a "Kenwood" cable connecting to a USB sound card so I can activate parrot (DTMF 1#) so I can hear my transmission repeated back.
Just purchased a quangsheng uvk58 and programing cable. I don't have a ham licence but want to use it solely as a handheld scanner. Looking forward to the chirp vid as I've never used it before. A firmware flash vid would be good too for us newbies..... keep safe pal, cheers.
Hi. Chirp video up later today.
I have argued so many times with people about the frequency ranges in radios. Sre some radios can be opened up to listen to frequencies well outside what they are supposed to. Just because you can hear a frequency doesn't mean you you can successfully transmit on those se frequencies!
Yes spot on. Well outside the radios capacity.
Yes, me too. Even though the IC itself is able, the circuitry is just not capable of transmitting certain frequencies.
the new Beken BK4819 is different check out its data sheet
the UV5R and most other dualbanders use the RDA1846
@@CB-RADIO-UK No it isnt, see the Beken BK4819 datasheet
Its only TX PA filtering thats limiting it
Modt u can tx vhf 137 to 160 no issues and 420 to 470 mhz, we use to use all sorts at airshows on various opened radios, discrete freqs illegal of course
hey my opinion is dont use the desk charger atleast not in the same space as your cb radio,it interfair it create,s alot qrm when you put the handheld in the charger
got the quansheng uk5/8 the other week great little radio , airband reception is toss but i think the firmware upgrade sorts it . good vid fred looking forward to the next one.
Frid in the shed your utube videos are awesome my friend
also in the new filmware come with a am fix the sound quality is much better then,also you get a s meter and you can turn your mic gain up till 15db
In US, CTSS is used to open up repeaters.
I have the UVK5 and it recieves and transmits on the GMRS/FRS 462--- freqs very well. You can unlock this radio to transmit on most bands. You might need different antenna to max it out.
Is there a tutorial on how ?
I use this as an excellent all in one scanner, with the 0.21 Egzumer mod: I listen to the airband (CLEARER than my actual flying radio), to CW on 28.025 to 030 on the USB, to all the CB band on FM, AM and USB, and the vhf ham repeaters, as well as the PMR which I programmed. For fun I transmitted on the commercial FM radio with the Fagci mod which lets you transmit on any frequency (of corse as you mention it is useless with all the harmonics…). Spectrum mode is a good scan alternative for singling out the peak station. Memory scan is very fast! Frequency s an is correct.
For $20 its a pretty good receiver, I do the same with mine.
Just got my quanshang radio this weekend this afternoon took it to stanstead airport Burmer Rd plane spotting area and wow the control tower and approach stanstead channel s was clear you could hear clearly the conversation between the tower and aircraft as they land and take off in am mode I paid 23 quid!! For mine off eBay
Great video Fred
Ordered both Quansheng and ATS 25 after watching your videos. Think i may have to do a HAM course to get more knowledge.
Hi. Yes a great idea to really open up the hobby.
FRED thanks that was great timing got my self a Balfug UV5R and it’s great. Yesterday I ordered a UV5R+ or it’s called a UV5R H , sorry can’t remember but I know you know what I’m on about. It’s got I’m shore 3 band if I’m saying it right, with AM AIR craft. BALFUG . With the little green button on it. Can’t wait to see and hear it. But what you were saying about programming , is something I really do need to see. Got the leads and the disk for programming but I’m not got a computer. So I’m ready for you break down on how to do that. Thanks again and and I’ve ordered a sirio 5000 , because I’ve moved to Leighton buzzard, and I don’t won’t to push it at the moment. Anyway sorry for going on. Thanks again for letting us see how everything works on your channel, because I understand it because the way you explain things. Thanks again Alan from Leighton buzzard 🇬🇧💯🍻👍👍
Cheers Alan. I totally get the programming thing as i rem it broke my head a few years back with the UV-5R. Video up later today which is very very clear and slow. You can just use the keypad which is slower but works. I did it recently on my RA-89.
@@CB-RADIO-UK thanks sorry it was a long cheers 👍
I commented on on of their videos showong it off that its just a rebranded quansheng and well funny enough that video disappeared also someone was asking if the "maker" of that video as they referred to them as could make changes in the radio and i replied "Its a Quansheng UVK5 i recommend looking online for a tutorial to modify said radio" and i get greeted by a reply calling me an idiot, that was fun well i replied back "Ignorance is bliss" and boy did that get the person riled up they were calling me all sorts of names.
I ve now got a original UVK5 and i have run them together and they are they same. The K5 has a slightly bigger battery.
Frid in the shed my hobbies are painting pictures 🖼 and listening to shortwave and ssb iam thinking about getting my ham license
I've done the Nescafé Gold mod , great firmware , it's better than the Maxwell HSE update , it will be better when hopefully it can add 1 spoon of sugar and stir my Brew on the next update ,, I gotta say the VAX is better than VOX mod, the floor is so clean , cheers Fred
LOL.
Hi Fred, That Chirp information was very useful, Many thanks.
Glad it was helpful!
Frid in the shed Iam thinking about getting a hand held CB radio with AM fm ssb my friend
Great introductory video as always for people wanting to expand on their radio interest.
If it’s the better accompanying manual you wanted, I get it, but at £30, I’d be wanting x2 of these.
Can’t see any point in paying £30 for a better guarantee, at £15…I’d just flash it and lash it, and buy another if needs must.
Cloning…I don’t think that would happen.
Boafeng might fight back with their own wide band chip version though.
With Egzumer 0.21 firmware works fine in RX on 27.555 usb but had to put a 88 108 notch filter on
😅😅😅😅😅
nice video Fred got me thinking il look in to getting one of thoes radios only to see would i get it even to recive on 27mhz. with the chirp software, wishing you a happy new year to you Fred and all the family
I believe pressing the A/B button for a second or two also does the same as using F + 2 (with the ezgumer firmware it does, not really sure with the stock firmware).
Thank you. from Thailand
Don't worry about "harmonics" from a five watt radio. Microwatts emitted from them would bother no one unless you happen to be the American FCC trying to stem the flow of Chinese radios into the US.
Would love to see you do a video on programming pmr manually including the step function !?!😎
Solid performer, Quanshang version cheaper and great quality.
You need to get more air to the radios in the background. Covering them like that makes for breakdowns caused by overheating.
Fair point. The desk is fully open at the back so they do get air flow.
@@CB-RADIO-UK Great stuff, and I really appreciate you replying, which is rare with others. 👍
4:55 No Fred, it will not be cloned. It will come off parallel production lines and cross branded just like yours is.
Yeah your prob right.
In the USA, where a ham can modify a radio anyway one likes I plan on modifying the internal filters to put a couple of UV-K5's on 10 meters and perhaps 6 meters instead of 2 meters and 70 cm. A TinySA and a NanoVNA and a handful of SMT inductors and caps and it's magically a different radio. Should be fun.
Happy New Year Fred :D
same!
Happy New Year guys
Hi I’ve bought my husband a Retevis RA79, purely to listen to aircraft’s, but I cannot work out how to set it up.
Do you do a video as to how to set them up at all.
I was hoping to receive it and just turn it on and listen. lol.
Hi. Sure this video should help. ruclips.net/video/DvgmHrCYJkA/видео.html
14:52 did I just hear 8 out of 10 cats?😅
Why cant they do a UHF version ,nothing on Vhf except Aviation band worth listening to .
Fred, seriously now , I don't care what they're doing with these mods , they are not a Yupiteru , I think they're as deaf as my great great gran
cheers fred yet another entertaining and informative vidio. are you considering getting the thunderpole tx. ? cheers and beers DJ.
Hi. I think the Thunderpole is good value compared to the Alan 42 but they really do not work that well unless you take them DX. We are all too spread out these days.
Hi I have a Retevis rt23. I have had it nearly a year and havnt heard a thing on it. Indoors I get about 4 bars of static. The bars only drop when I put squelch on. Not sure how to get fm on it either
Try pressing the "exit D" button to get your A/B switching
Thanks i will give it a go.
You should make a video flashing and showing off the egzumer custom firmware on that thing! I get it's been done a lot but still
Yeah i prob will go down that route.
Hi, usbc conector is only for charge
Fred show us your face for 2024 ... Oh common in all fairness. Great video tho. I am waiting my quansheng to arrive... 73s
Nice one Jimmy. Look at the 42 year net video.
@@CB-RADIO-UKwhat do you mean ? 😊
Watch my 42 year CB net video :-)
I got this just recently to listen to airband frequencies..can you recommend a decent antenna for better reception on this?
Hi. Yes antenna shown in this video. ruclips.net/video/DwE5rg8-95M/видео.html
Have you got your hands on the original Quansheng uv-k5? Would be interesting if you did and share some thoughts comparing both models. Everybody keeps saying they are the same, but are they...? I feel that Retevis, being a respected brand shouldn't fall behind when they clone radios...
I think other channels will prob do compares. Some people are saying that they are the same. It would be hard to call without totally stripping each radio down. Only thing i say for Retevis is that you get a 30 day money back if your not happy with it.
270 cm should correspond to 111 MHz. Should I expect this radio to transmit somewhat decently in the Marine VHF frequency span 156-162 MHz (about 192 - 185 cm wavelength)? Maybe with a suitable 1/2 or 1/4 fraction wavelength antenna (94 cm or 47-ish cm long)
In theory it should work on the marine band. However its not tested.
@@CB-RADIO-UK Thank you for responding. I guess the major frequency limitation is inside the radio and not in the antenna. Is my antenna length estimation optimal for the marine band, or are there something I totally misunderstood about frequency/wavelength vs. antenna length?
you can just hold the 2 button and 3 you dont need to use the f key :)
Thanks.
@@CB-RADIO-UK oww that dont work on the factory filmware,i didt know i flash the new filmware right out of the box hahaha
Will it communicate with mcdonalds i want a Aberdeen angus burger 😂
not anymore, up till about 5 years ago they used around 456 paired with 462MHz
or 453 with 459 on the drive through radios. i think they moved to around 800MHz
You’ll be wanting Burger King for the Aberdeen Angus!
Just bought one from aliexpress cost me ?10.28... yup cheap going to download firm update tomorrow 👍👍
Wow that is just crazy cheap !
back in stock at AMAZON UK
Good news
so funny the clone stuff and the real deal, and i think the Clone stuff is as good
Hiya Fred. Currently sold out on AMAZON on this date of my post. 73's
Yeah they sold out even before i got my video out. Still in stock at the main Retevis site.
Brilliant posts fred are you still on 305 regularly as would try to breaker In if poss best wishes to you and yours for 24 😊
Hi. Sadly they changed my work shift so I am no longer on the afternoon net. I believe the 6am morning net is going strong.
It picks up CB great.
Will be testing that in the future.
When you say don’t use this for CB, are you talking about the HF 27MHz band? Half the reason I just bought one of these is so I can use it on UHF 476MHz. Will this still be fine?
Hi. Is that Australia CB ?. I ve not gone higher that 446 but it should transmit although the power will prob reduce. It would help if you could find a SMA fit antenna for that freq.
@@CB-RADIO-UK yup, this is for Australia. I didn’t consider that the transmit power might reduce, but we’ll see how we go and I’ll report back. Thank you for the reply! P.S. I also have a Nagoya NA-771 copy on the way as well.
Billy no mates 😂😂
My biggest gripe about this and the Quansheng: no VFO knob.
Yeah. Mind you i cannot think of any 2m70cm handheld which is not button driven.
@@CB-RADIO-UKEven though I can't stand the menu system on the Yaesu HTs (or Yaesu in general) it is the one thing they really get right: the dual volume and vfo knob. Appreciate the video. This is a really interesting set of radios... I'm more inclined to think of them as an HT platform at this point.
Why is 270 cm (111 MHz) described as UHF? Isn't UHF correctly described as "The UHF band comprises the range 470-790 MHz and is used for the transmission of various digital terrestrial television (DTT) channels and for wireless microphones in all EU Member States."
Yes i would have thought that 111 MHz would be VHF ?
When I google 2 meter 70 cm I get results that make me believe that this is two different wavelengths and not 270 cm wavelength. 70 cm corresponds to 428.275 Mhz and 2 meters (200 cm) corresponds to 149.900 MHz. I don't know for shure what is right
my mate has one and mines coming soon.. sunday 5/9 both ways 52 miles hill top to hill top.on 446 ch 14. I think 80 miles will be the limit no prop...
You will need VERY good conditions for that contact. You never know though.
