You’ve saved me the time and effort of doing my own receive measurements. I have checked transmit and I was gobsmacked at how clean the output is on 2m and 70cm. Above 500MHz and VHF Low-Band and below it’s as dirty as a two bit whore, which is to be expected. Airband receive with the stock firmware is a non-starter, but some of the custom firmware options have addressed this.
I have one of these little radios and I was super impressed even with the stock antenna
@@14KiloWhiskyIsn't that what this video just did?
Thank you for this excellent demonstration, quite remarkable. I am pleased to see the cows seemed quite relaxed..
Good to see you back again!
Interesting video and you make a good point. There is a bit more to performance testing than a signal to noise test, it's fine when a tech is aligning a known receiver, but then again a receiver with no front end would give you the same results or better results. Adjacent channel rejection is a big factor of over all performance especially with VHF / UHF as the front end filtering is generally so wide. You would need two signal generators, it would be interesting to see how well the Chinese radio stacks up.
Evening Paul brilliant video mate I have two off them,, and thank you for sending my brilliant test meter I received it all OK
The main thing that sets apart the big brand radios from the budget minded radios is very basic. It is the price. Most use the same final amplifiers, batteries, and components. A really good example I noted recently for repairs are the Yaesu FT-8900 and the TYT TH-9800D. I had to replace the final amplifiers on both. Both had the same Toshiba 2SC5375 amplifiers. When I set them up, both had the exact same setup menu. Same final RD70HVF1 for VHF in both. Do yourself a favour and just buy 10 budget minded radios for the price of one big brand radio and pass them out to people in an emergency, or give one to someone to start a hobby for them.
Problem is cutting corners in the design, for example in the 9800 and 7800 from TYT they have two ICs that must operate between 3.3 and 3.6v, max rating with risk of damage and no guarantees on specs is 4.5v, the genius behind the TYT designs is feeding them almost 5v, but the worst part is that it seems they did this to "improve" sensitivity, cheaper than designing a better front end, compare the Yaesu front end with the TYT, TYT should have done it SDR receiver if the weren't gonna copy the receiver in a good and funnctional way.
If you dont modify the TYTs they are a time bomb, mine is modified and sensitivity has come down.
Yes Knoxieman! I had just asked for one of these for x mas just to have as a spare . Def looking way nicer than a boefeng!
Best HT I've ever owned , completely satisfied with it ..
Thank you for the thorough review of the UV-K5(8) aka UV-K6 handheld. I have been playing with mine for about a week now and and have found its performance to be pleasantly astonishing. I could not help myself and ordered another one so I would have a matched set! 73, W1AEX
Try the Quanshang UV5Rplus version, comes with a bigger battery you can use on your K6
and its cheaper than the K5, all it lacks is the USB C socket
@@user-em6vi6sj7p I have been looking to see if Quansheng will offer the UV5R+ battery as a separate purchase. Hopefully they will at some point but if not I will probably take your advice. Thanks!
I flashed mine with UVMODS firmware and am impressed with what this little radio can do. In this case the Chinese have a winner, most of my equipment is US or Japanese, but I have bought a couple of Baofeng's to give away to scouts, and for prepping, now this Quansheng to play with.
This thing is a real killer: Professional, sturdy look&feel, USB-C-charging, modifiable firmware, backlit keys, excellent B/W display (non reverse!), FM-radio, sold for almost nothing.
no usb-c charging,
@@MauricevdfHermsen oh yes it does
my second one does charge USB-C ... first one broke after 2 weeks. now i'm happy!@@Dycdom
@@DycdomIt's behind you. Oh sorry, though I was at the panto. 😂😂😂
They're good little radios, not perfect, but great for experimentation.
Interesting video, thank you for sharing Paul.. How do you find the receiver on the AM air band?
I highly recommend Paul's Sinad meter mine is brilliant money well spent👍
Good comprehensive review.
Excellent video!! Very well done on the testing and analysis! can you please give more information on the Sinadalizer. I realize you are in the UK and I am in the USA but could you provide schematic information or a website where more detail about the circuit can be found. cheers and 73 (Edit: I just found your other videos on the Sinadalizer and am watching them now)
I had another one of these delivered yesterday for £10.90 delivered aliexpress. Incredible little HT
Been meaning to pick up one of these radios for a long time, good demonstration of the radio as stock, I also ordered one of your sinad meters before they all sold out, been meaning to buy one for radio repairs and tuneups for a long time
The new firmware is totally amazing.
It allows receiving from 18mhz, with am/fm/ssb modes. As you said, it also allows transmission on some additional bands such as air band! So this is a "dangerous boy" 😂 (albeit with very limited power, fortunately)
Well worth the money!
watch some review before my uv-k6 arrive.
thank you for your review.
Loving the Quansheng and of course SSB receive too. Times are changing with radio these days
If the digital part of my Yaesu FT-991a quit working, I wouldn't miss it a bit. I hate digital Ham radio. Cheers from eastern TN
Selectivity, IMD, etc are more useful measurements. But no one on CZcams does the measurements that actually matter. I'm still curious about a head to head comparison between this radio and the original version of the radio. Are they electronically different, or are the changes merely cosmetic?
I have both radios. Up on a hill top the quensheng was swamped and overloaded with a nearby transmitter. The FT70D however was ok. I was calling and calling on 2m using the quensheng and wasn't hearing any replies yet I was told several people were calling me back. When I tried the FT70 I was able to work those stations no problem.
Best audio of all HT with the extra firmware.
Good bang for buck. I will do the mod and use it mainly for receiving.👍
The Quanshang UV5Rplus is the Baofeng UV5R killer, its a K5 made to look more like a UV5R
with a bigger battery that can be made to fit the K5 but without the USB C socket. and cheaper
than the K5, its worth getting for its Larger Battery alone
Welcome back.
The (copy?) Nagoya didn't really improve on the original antenna on the Quansheng.
Most 771 are too short and dont resonate anywhere, except perhaps 220MHz
I like the AnyTone HT's. Big battery and speaker are important for me.
I once bought a Icom 2820 and id51. But the quality was really bad. The price was huge for that.
Now i'm using a Chinese FT2980 and a Anytone.
Ive had more fun with the uv5r and AnyTone, then with those overpriced Icoms. And they ship it with extra's.
Something those big brands can learn from.
I use the baofeng for monitoring and occasionally TX on marine band
I've recently bought a couple of these k5 and they're great little radios. I've just also got hold of a couple of uv17 and theres nothing in it.
New generation Chinese radios are the way forward
The UV17 Pro V2 are higher power, at least 6 watts, Baofeng are now using V2 in the name
to signify the high power versions of all the new handys
(V1 standard 4 to 5 watts, V2 6 Watts plus)
What is the difference between a k5(8) and a k6? I keep seeing are for these but they look they same?? Is there a table somewhere?
What's the use of the flashlight on Baofengs?
To help you find your good radio.
£25? Thye are around £15 (€18) on Ali..... With the new firmware the AM reception is way better then it is out of the box. Super radios. Can you do this again after installing the newest firmware? Nice informative video.
I paid £9.69 for mine from Ali, with free shipping, it was due to arrive boxing day, I got it on the 23rd
Just ordered a second one, paid under £11 for the first one, second one was a hefty £17.... well worth the change of firmware. HF SSB receive is quite a novelty from a handy, albeit with poor sensitivity. No idea what the dynamic range is like, not intensively tested it yet, hopefully better than the UV5R...
The radio comes stock with a multi band antenna, switch to an antenna better suited for the frequency.
The stock compromise antenna is a jack of all trades, master of none.
@@juanbait9670 I have not tried a "suitable" antenna for HF receive, the stock antenna does a fair job on 2m/70cm, there really is little need to compromise on these bands.
I may try it on one of my HF antennas, certainly the actual receiver sensitivity is not great at HF frequencies irrespective of the antenna.
Great video. Do you have any contact details? I wanted to message you directly about a replica antenna prop you produced in the past.
Excellent discussion on the Quansheng, really appreciate your work in putting this together. Overall performance is quite good and I'm very satisfied with my UV-K6. Do you think these Chinese radios are spying on us?
How? using the 406MHz (somewhere around there?) cloning frequency they all have in them? If so there's a reflash to change the default frequency.
Only when they are modded are they good any of the quansheng models
The reflashes are worth having, for the improved AM RX alone
@@user-em6vi6sj7p yes I agree
has anyone tried the built in cross band repeater? Can you confirm if it works?
Uuuhhh. K5 with 770 is booming. BUT: Yaesu has nicer modulation.
K5 can be reflashed for more mic gain
Yes they are not perfect and you get what you pay for but for the money they are amazing if your just a regular person just slightly interested in radio go for it they are cheaper than a take away meal !
Really got my hopes up and then realized it's RX only air band. 😩
Hello Paul Nice video and locations. Banbury way. I got a Yaesu FT70D (some YT videos I did) and an old school 2nd hand Baofeng I think is nicer. They ok in really early days I was told, 2013 model or so radio but guess not that old, still can buy, ok could when looked 10 months ago when bought it for £5. UV-B5. Done tests to myself on SDR as you or a local play along and listen, talk to me when cranking power up and down and changing radios and antennas, He is patient!. Baofeng chuck out spurious emissions, maybe not as an old model when think they where better. Cant test, no idea but tend to use that one out and about as the digital a complete waste of time back home. works in a few high locations a walk or bike ride away locations the digital to Fusion access points if on the longer antenna. Got genuine longer ones for both radios as opposite connection, one to other. Nice video. FD70D a disappointment but as in a comment, if out and about in RF noisy place bet I know what would work better and not chuck out nasties everywhere, Still a test at home, Cheap chinese was better but in reality, guess not. Right by some radio station, mobile phone mast, Big transmitter. Any good then, who knows.
There are 2 versions of the Baofeng UV-B5 the original ones serial number start 10
and the later ones serial number starts 15
@@user-em6vi6sj7p hello Stephen. Found you qrz. No photos. Proberly the phone. Have a got old or new. Will see later.
Cant get the battery out. Pack up with things in the battery slots, it was loose. Pain to take off, Cant to to info sticker under it. forgot that. Is a nice radio. Yaesu one tends to stay at home if going for a walk, no point taking digital one as only 2 places that work if lucky when get some height. Digital a bit of a non thing in the way of repapers where we live.
this is the k5.8 version the orinial k5 is fully black
Imagine what they can do if they put in a bit of real effort....
Might be a daft question but I'm new to this, if you have two of these can the ne used similar to a walkie talkie?
Yes, but you need to check local regulations to see if that is allowed, and on what frequencies.
Licensed radio amateurs can use it within the bands assigned to them, sometimes other bands are assigned to license-free usage (PMR), but it differs per country what is assigned and whether you can use these generic radios or need to use a specific type-approved model for that country.
@@Rob2 If they meet IR 2044? then they can be used on Business simple frequencies
if you buy the licence £75 for 5 years
@@user-em6vi6sj7p Again, you need to check local regulations. It depends on where you live. In some countries there may be no radio regulations or supervision at all.
@@Rob2 thanks for your reply, I assumed this was the case.
One thing that bothers me a little (they all have the same problem) is that you can't use an external microphone for repeater use. When receiving the repeater it won't go in TX. No problem when pressing the PTT on the hanheld itself. Seems a weird bug somehow. But I can live with that for the price of it 🙂
That is probably intentional and maybe configurable somehow. It is done to prevent transmission on top of others in simplex use, also in VOX mode.
You may have the no TX if busy switched on?
@@Rob2 No config found, it goes in tx if pressed the ptt on the set itself , just not with an external mike
@@user-em6vi6sj7p Nope :-) Checked that first.
Has anyone performed a cyber security test on these radios?
한국어 자막이 없네…
Jumped over the lazy dog,not lady dog .that way it uses ever letter of the alphabet
8 months too late to the party?
? He is perfect on time I think
My radtel rx 470 receives better than my ft 70 d.

Not, it does not. Compared to a simple Yaesu FT-4X, it is deaf as post.
quanshen is a nice,cheap toy.... My Albrecht ea 2990 AFS is much better on 10 meter ssb. MUCH....
Don't waste money with crappy things... Just buy real gear 😅
I hear you, but don't waste money dragging quality items through the mud, either. It pains me to say it, but these things are as disposable as a carton of beer. Who cares until next Friday.
@@davidbrayshaw3529 why not for outdoor activities like hunting... You're right 👍😉
@@14KiloWhisky I love "nice things". I really do. And it goes against my grain to call something "disposable". Damaging or losing an ID52 is going to spoil your month, not just your weekend. With one of these things, you're probably not going to draw breath to say "whoops", if you cook it.
And as much as I'm a bit of a perfectionist, I'm getting older and good enough is something that I value more, now. These things have their place.
@@davidbrayshaw3529 you are absolutely right 👍
Dont be fooled by the cheapy Chinese Radio....They are as wide as a barn door and not very selective in noisy environments. The Spectrum on transmit is also a mess with lots of Spikes out of band. Yaesu have filters and are spotlessly clean. You pay a lot more but thats the reason. Also if you read the instructions DO NOT CHARGE BATTERY VIA USB
I cut the end off the USB cable it comes with for a project, it only has a black and a red wire in there... Makes the do not charge! even more stupid.
Puzzling you think this is filthy, since it's been tested as very clean by several youtubers on video.
@@de_w8tam He may say it a bit bluntly, but it's true that transmit TX can sometimes be a mess, especially if you use Freq out of band.
I'm just interested in the AM air band receiver quality which I'm not expecting a super result
Remember we’re talking about VHF/UHF, for most uses RX will be functionally the same; most people aren’t doing weak signal work with these anyways. Of course this is anecdotal, but I don’t have much performance difference between my Yaesu and Quansheng
icom kenwood yaesu is master piece Chinese radios trash.
What a nice review! Thanks for your time mate! I am subscribing right away ; i ordered one of these a couple days ago from AliExpress and I'll see what I get ;)
