- Here we take a look at the Baofeng UV-K61 Tri-Band hand held radio. Yet again, this one fails miserably. How hard can it be to design a radio that does what the specs say?
Luckily, it's not very expensive, especially with the below coupon.

A cheap chinese clone of a cheap chinese radio. What a world we live in. The Quanshengs deliver so much fun for so little money already, why would anyone get this one.
A lot of these radios are sold under different brands. I expect this is the same.
@@paulsengupta971Yep, I found them on local shops branded "Texas" and amusingly it's cheaper than Quansheng's 😅
I really wish baofeng would make a 10, 11 and 12 m tri-band walkie-talkie that did all mode AM FM and sideband, I know so many people including myself that would love to have one of these radios
I agree, I managed to get an SuperRadio / Albrecht multi mode Handy with SSB and a Clarifier, memories. Mic port, Small wire snip to open it up to 24Mhz - 30Mhz . And even something to challenge a Yaesu FT817 portable multimode rig. would be a smart move but way more of an expensive challenge looking at Yaesu's amazing build quality. .
Absolutely! FYI, Rumour has it that AnyTone might have something in the works :)
@@mostlypostie1 nice
@@mybrighton lucky, those are as rare as hens teeth, I'd love to get my hands on one.
You can get a Jopix CB-514 handheld that does 11m, as intended, but can easily be widebanded.
With the radio off, hold the PTT and FUNC button at the same time, then turning it on, you can wideband it after selecting the correct table. Table 1 is CB, which can be selectable for the country you are in. Table 2 is wideband odd frequencies, and Table 3 is wideband even frequencies. Thus, the tuning steps can be set at 5KHz by changing between Table 2 & Table 3. There are a further 3 tables, but these seem to be variations of different CB channels. In wideband mode, its frequency range is 25.61000MHz to 30.10500MHz. Unfortunately, it is only AM & FM only.
I believe it is a version of the President Randy, but at a much cheaper price.
The Quansheng has exactly the same problem with AM. The Egzumer mod on the firmware delt with that. Looking at the box of this Baofeng you cannot tell the difference between the Quansheng and the Baofeng... so... I don't know but it seems to me the same manufacturer?
I would suggest it's the same radio. I would suggest that it be flashed with the Egzumer software. Go on, Mat, try it.
Quansheng has less buttons.
@@stefanp4258 Hmm, yes, maybe not quite the same. Maybe not quite the same firmware then.
Maybe not exactly the same radio but the same manufacturer.
If that's the case it excellent news lots of mods ++
My TID TD H3 and H8 radios are not clean on 2M or 1.25M and are generally pretty dirty on 70Cm as well. There are clean Chinese radios, but even within a brand, there are wide variation on spurious output.
I have 2x UV5R's . That's enough junk in anyones life ! (owned for nearly 4 years and still working fine on 2m and 70cm ).
I know that some sources disagree, but the TinySA only puts a "1" on the fundamental because it labels peaks in order. But it's not a harmonic, it's the fundamental. The harmonic labeled "2" is actually the first harmonic, not the second. The "2" simply means it is the 2nd peak.
And here is me thinking that it is properly known as the Fundamental Harmonic. This is what I was taught.
@@TsiolkovskySportingLocks Like I said, some sources disagree with me. But a fundamental is a fundamental, not a harmonic.
@@TsiolkovskySportingLocks Think of it like on a guitar. You play a string. That's the fundamental. You touch it at the octave to make it vibrate in halves and you get a note twice the frequency of the string. That's the first harmonic.
I was always taught 1 is fundamental and 2 is first harmonic, but when I said in previous videos that 2 is first harmonic, I got flamed in the comments more than a witch burning at the stake! So now I just say fundamental and second harmonic and 99% of people know what I mean.
@@TechMindsOfficial The sad hams that are flaming you probably could not even explain what a balun accomplishes. Ignore their ignorance. It is astounding how far amateur radio has fallen from being a technical hobby.
Oh dear... I have several of the Quanshengs, and even a Retevis "Quansheng" clone. None have spurious emissions over what is the acceptable limits, so Baofeng certainly had a wobbly with this one. Steer clear of this one.
I bought a quansheng kv5-8 about a year ago. I've left it alone and not upgraded the firmware. It cost around £12 delivered. Less than a pizza. I'm not technically minded but I've used it alongside a couple of baofeng UV 82s and a uv21 (bought at a car boot sale for £16). Both brands perform reasonably well. I've swapped out the antenna's for what are most likely fake Nagoya's. I'm assuming they are however the do perform better than stock. On all these handhelds I can usually hit a repeater that is roughly 7 miles away. I do have to go up to my nearest high point and I'm still impressed that they get out that far. I speak to contacts who use Zello and other network stuff but as a free standing walkie talkie not using any other tech they do seem to work. The AM on a standard Quansheng is just about listenable, if you're into that, or really bored. Pmr 446 is interesting. I do have a licence but I'm still not quite sure of using a 5w radio (or more) is covered on this band. That being said, it feels a bit like the old fashioned CB in that people are bending the rules. Which are ment to be bent. On a side note I bought a CB radio during lockdown. Running a big old base loaded 6 foot whip. It was great on the 11m ssb but the UK channels were either dead or some guy playing music on ch 19 with an echo mike at about a 1000w. Some things never change.
Thumbs up for using _shite_ to good effect, especially with the follow-up chuckle
Another great video Mat. Minor point: we would say the 2nd harmonic is -18db down from the fundamental, not -18dbm. -18 dbm is an absolute power level. -- Wayne K3WM
Why do you have a line through the text?
@whiskeymike5154 bloody script writer is getting laid off! :-)
I don’t think any of these radios should be able to advertise airband when they sound so bad on airband. That noise actually hurts my ears.
They can be flashed with software which will make it right.
Lol, thank goodness you're not in charge here
AM is often poor on chinese radios... is this a case of it being exceptionally poor?
I can test for myself, 1) too small a sample size and 2)not near an area with airband traffic.
Would you consider this for a future video? Chinese radios and their performance on AM?
The quansheng uv-k5 was unfortunately, everething is the same. Now, if FT8 could be transmitted then device would be useful mega.
Hi, Which one is the brand you recommend at the last part of the video? could not get the brand right as my Listening English is not that good .
When a Chinese manufacturer has to clone another Chinese manufacturers products, you know they are very desperate for sales.
I thought they do it because it’s easy money and there is no intellectual property protection in China.
I think these are all coming from the chip manufacturer - I think “clone” is the wrong way of considering this.
It’s a generic white-label radio where a manufacturer can just buy it and have it styled as they wish. It’s not as if Baofeng, Quansheng etc are rolling these boards - they’re mostly just brand names.
Baofeng are pretty much finished in the $20-$30 radio market.
Quansheng have accidentally created a Monster with the UV-K5/6.
Given the emissions harmonics noise, this is definitely NOT made by Quansheng....
So Quansheng cloned Baofeng and now Baofeng clones the clone.
What I dislike most from Baofengs is the huge size of them. At least this is smallish. This looks like a rebadged QUANSHENG UV5-R plus, not a counterfeit, although the air band sounds worse on this one.
Claims about "spurious emissions" are spurious. A five watt radio's 'spurs' are in the order of microwatts, and shall cause no interference at all, unless your😊 radio is FEET from the offender.
The American FCC was concerned about the huge numbers of cheap Chinese radios entering the US., so came up with the 'spurious emissions" rule to control the numbers getting into the US., some other countries adopted that too.
You said you'd never ever reviewed a Baofeng angai -_-, just like i said to my wife i'd never bought a radio again 😅
thats either a deliberat clone or manufactured for Baofeng by another outfit, may be even Quensheng themselves. I wish theyd just spend a little time getting an all band radio to work right, ide buy it even if they had to charge a bit more for the extra dev time & compnants becuese it would still be cheaper than the like of iCome ect wich i simply just can not afford.
You should have tried to load the Egzumer firmware to it.
Interesting idea, albeit, this radio may have a different chipset?
@@l.a.2646 LOL, they're all the same, this one is also branded Quensheng UV-5R with the bigger battery and blanked off USB-C port.
On AM it has the same issues as Quansheng
The analyzer results should be considered as only a data point, and with a grain of salt. Keep in mind we're testing cheap chinese radios with cheap Chinese analyzers. I've been seeing way too much stock going into what those readings show than there really needs to be.
And I've seen reviews where they appear to be massively overdriving the spectrum analyzer and likely creating harmonics there. Not necessarily here, but another YT channel. Yes, grain of salt.
@vitogriffin8902 Actually, the TinySA Ultra is extremely close to top end gear in terms of harmonic measurement.... That's not just a "out of the air" statement, I have seen it tested.
@JimAndyAllyn You can work out how much power is going into the TinySA Ultra by looking at the attenuation value and the peak dBm of the fundamental.
@@TechMindsOfficial I've seen them used beside higher end analyzers and be pretty far off... I guess that speaks to the quality control of the manufacturers putting out the cheap electronics. Either way, there's more going on with the harmonics and what actually causes interference than an analyzer graph and an FCC standard. Everything transmits on the neighboring harmonics, and I can hear NOAA VHF broadcast on 49-50mhz, as well as some of the local VHF ham repeaters .. the difference is that those are putting out a couple hundred times the power of some HT that you'd have to be standing on top of in order to get any actual interference. It's much ado about nothing. LED lights, motion detectors and security cameras cause way more unintentional interference than any HT. It just doesn't really happen outside of the testing environment.
I use a direct connection, through 30dB attenuation with the radio normally around 1 watt output. I have performed the same tests with Yaesu, Icom and Kenwood radios using the same setup, and none of those have high harmonics. So I think my TinySA ultra is proving the point. Every time I show spurious or harmonics, someone always pipes up to tell me I am doing it wrong. I am sure that even if I had a £5000 Spectrum Analyzer someone would say I'm doing it wrong...
To be fair the Quansheng out of the box sounds just as bad on the airband. Same goes for the h3
This is a BAOSHENG ! 😂 .
I hate blue screens , it's hard to see, same old poor signal meter, same AM flaws as the Quansheng UV K5 / K5 (8) K6 that is easily fixed with Egzumers Mod on those radios only. No Antenna tests yet I see so I'll stick with the 100km Quansheng to Quansheng K5s range test l saw both using the stock antennas. 1 extra button on the front so don't be trying Egzumers Mod just in case it bricks it. Get a Quansheng k5 k5(8) or k6 before you can't.
Nooo its terrible
smells like a poor clone
I'll go with the shite diagnosis
