MaxTalker TK-W70
MaxTalker sent over these radio free of charge in exchange for this video review.
This radio did a pretty good job on the testing. The batteries actually tested better than their advertised rating! The radios are fairly clean on 2M, but have a 2nd harmonic problem on 70cm band. The receive audio quality has something to be desired, and broadcast FM radio doesn't sound too great. The radio does seem to be water resistant! The radio is advertised as a 10W radio, but only puts out about 8W on 2 meters and about 7W on 70cm. The programming software is functional, but nothing too special.
Quirks that I will probably do a follow up video on:
1) No DTMF tones. You can't control repeaters or hotspots with a lack of DTMF tones on the keypad.
2) The radio actually seem to transmit EVERYWHERE! Not a great thing! I will try to look at output power on alternate frequencies, specifically 220 MHz.

Baofeng UV-5RM. I'm not sure I can figure out what Baofeng is doing. The UV-5R series of radios finally after years seem to be clean now (at least the all the recent ones I've tested,) and then this radio is a "newer" version, and they seem to have forgotten all they learned on the UV-5R!

Baofeng UV-5R! Are these radios actually CLEAN now?
Lol I haven’t pushed the send button since I purchased it.
I have a pair of UV-17R that came with firmware 0.01. Useless. In your travels did you find a way to upgrade the firmware on these units? Baofeng support said NO but I don't give up easily. This version can't xmt on ham bands but I think starting with 0.08 the radios do! Along with other functions.
What is the website ? I can’t find it Thank you
Very nice review! I would be interested in a video with a list of radios you have tested that you consider spectrially clean.
why would you even put a $35 radio on an anylyser? did you put your baby monitor or garage door opener on the test also? How about your cell phone? send them to me if you just cant stand owning it Ill share them with real people who would enjoy them. Tom W8FIK
That's great! We always wonder if a radio is what is says it is. 👍
As a noob just starting into amateur radio I was looking for a radio to dip my toes in with. From the get go I want to be clean transmitting and this video has helped me. I now know what not to buy.
Thank you for the comment and for watching!! Welcome to the hobby!!! 73!
You're a bit too narrowly focused on the 2m harmonics issue. For $29-$30, you get a tri-band, fully unlocked radio that can clone another radio's frequency and tones with 1 button press, includes a scramble function (not real encryption of course, but it'll keep neighborhood kids from understanding what you're transmitting), its tough, expendable as its so cheap, transmits higher power than most HT's which are limited to 5 watts, and has a large battery with USB charging. Kind of an unbeatable value in my book.
I will not argue any of your points. The issue here isn't "value" or "features," it's that the radio is technically illegal to use in the U.S. Any amateur radio operator should be concerned about their radios operating within the requirements of the FCC which grants us the license to use the frequencies we have. Also to note, the "scramble" function you mention is also not legal for amateur use, or for use on FRS or GMRS. With all this being said, everyone is free to purchase whatever they like. I just try to inform fellow hams that their money may be better spent on radios that are legal and perform better than radios that don't. In the same price range you mention in your reply, you can buy clean radios with the same functions. A good example would be the TIDRADIO TD-H3.
@@KC4NWK Fair and logical points, with regard to the 2m spurious emissions, though 70cm was clean based on your testing. My main interest in radio comms is for emergency prep & occasional use during convoys with friends in the back country, so legal considerations are secondary to me. Of more concern is to be a good neighbor and not interfere with others via harmonics on 2m. I will keep that in mind and limit usage there when using this HT.
I got the AR-5RM Problem solved and I can pick up aircraft transmissions. Awesome little unit
Does it mean AR-5RM is one of the clean radios from Baofeng?
Why do mental midgets focus their attention on matters of such insignificance?
Tidradio is hands down leading the HT race, only company I've ever seen to listen to the consumer and make updates to improve their radios.
Nice viedo. Have a question. I have bought new UV-17E, if the radio is on, it drains the battary in 5-6 hours even without any transmitting. Do you have any idia? The batttary charges in 2-3 hours with ca. 2400mAH.
I'm not really sure. You could check and see if the battery save mode is enabled. Check menu 3 and see if SAVE is set to OFF. For best battery life while monitoring, you could try to set it to 1:4. Thanks for the question and 73!!
Maybe I missed it. Were you testing in Ham mode, or Normal mode?
Thanks for the question. I have tested these radios in all different modes, and the RF performance is the same. The filtering is a function of the hardware, not the firmware. Thanks for watching! 73
Having worked in manufacturing for 31 years, im skeptical that Tidradio didnt just cherrypick 3 good radios for you to review. Id love to buy several of these but the first test results are very telling of normal quality in my experience. Hope im wrong.
I have a 5RM and have tested it for harmonics and found it to pretty great tbh, I think you may have got a hold of badly built one, or of course, I got a better built one. Either way they are cheap and most buying them seem to have issues even programming the damn things lol
I'm glad to hear that maybe there are some better ones out there. It is possible that I had a bad one, but from some of the other comments, I believe I'm not alone. :) 73!
Constantly saying uh is a little, uh, distracting. Your videos, uh, are, on the whole, very good and, uh, informative, except for this, uh, one little, uh, annoyance.
For $30 to get a tri-band that can Rx on all those other bands vs just a GMRS only radio seems a decent use case to me. Eg) use it legally with a GMRS license (and FRS), and never touch the PTT when listening on the HAM ranges. Harmonics issue solved, and you end up with a lot more listening functionality vs the identical chip in the 5G PLUS model that is GMRS only. Right? Or will it even suck on harmonics in the GMRS frequency ranges? Newbie here, so please dont scream at me 😅
The UV-21 got cleaned up months later.
Sounds like a sad ham. Baofengs aren’t for you. Channels that don’t review radios properly and just say “it’s a cheap Chinese radio, let’s put it through a test which the FCC doesn’t certify on and say it’s bad.” Will never grow. Bet you if you tested it properly, like the FCC tests it, you would find it performs just fine. They build them to pass FCC regulations, not an out of regs test. Videos like this are why many small sad ham channels will stay at 1k subs or lower.
LOL! Thanks for the insightful comment. Rather than trying to explain here in the comments, I would suggest you take a loot at this excellent video: th-cam.com/video/PvBk9BEUJQU/w-d-xo.html Also while you're there, you may want to let @TheSmokinApe know that his channel isn't going to make it.
What a b word
Alway this panic about harmonics. Bad harmonics on a base station you only use at home can be a problem in a city or village, but these radios are made for moving around off road, in the woods, moutains or desert. Harmonics are no problem in this case and no one will call the FCC and cry about it. Just don't use it as your main radio at home every day.
Hey thanks for the information! So are they any better now? How much do I need to spend and what should I get as an "acceptable" radio? thanks really appreciate it
Excellent presentation.
Thanks for watching! 73
I have 6 in cart. How do you know if these are the updated ones. Is there a batch number or date that determines?
TIDRADIO has indicated that Amazon stock should be current, as well as ordering direct from TIDRADIO. Thanks for the question. 73
@KC4NWK thank you
I have 6 in cart. How do you know if these are the updated ones. Is there a batch number or date that determines?
What does this even mean to Joe User? Why should I care about this?
I do these videos to provide information to my fellow hams about these radios that don't meet the requirements of the FCC. This allows them to decide if they want to spend their money on radios that are not "clean" transmitters. There is a possibility that a "dirty" transmitter could interfere with other nearby radio services or emergency services, and by the FCC regulations that hams agree to when getting an amateur radio license, these radios are not legal. All that being said, if a ham wants to spend their money on such a radio it is obviously entirely up to them. I just prefer to spend money on radios that are in spec and function as intended. Hope this answers your question. 73s!
Excellent Video 🖖
I like the crystal looking h3 versions,it would be cool if they would make the extra battery's also in crystal caseing.😁 It's not easy for a disabled person to read always the small displays ,Im wondering also if they have a option in the Menu to make the writings bigger or some other options.🤔
Another TH-cam says the GMRS version isn't as clean as ham version. Wonder if there's any truth to that? He felt they may additionally filtered.
In Europe minus 60 db for the first harmonic is required.
jsut looked up on amazon in canada. we have the baofeng uv-5r updated version under the name "baofeng 5rx" i wonder if they changed the name to avoid confusion
You do actually have to charge the battery before any power on comparisons. The UV-25 gooseneck antenna actually works better that the other one. I have 2 of the 25's.
TDA2822 is an audio output amp (stereo). I think they are using both channels in a mono "push pull" configuration for higher output. (just a guess) 73 OM
Thanks for the comment, that makes sense! ;-) 73!
UV - 21 Cannot receive and transmit in the range 150.0000 MHz -160.0000 MHz.
I got the TIDRADIO Bluetooth programmer to program the MaxTalker. MaxTalker doesn’t show up in the list. Tried UV-K5(8), doesn’t work.
What radio did you end up selecting? Thanks for the info!
Very thorough review and test. Thank you! 73 OM
Thank you so much fort he comment, and the view!!! Look forward to catching you in the comments again! 73!!
It’s thirty bucks! Who cares.. a cup of coffee is twelve dollars these days the thing is free not 1200 dollars…..
I feel dirty just watching this video...
Baofeng spurious frequencies forced me to give up my HAM license, disturbed my mental stability. I am now an unlicensed cell phone operator.
A few weeks ago I bought two of them through Amazon. when they arrived one of the radios was locked had to have a password to unlock it. I don't know what the password is do you have any suggestions ?
There are unlock codes on google, i believe it was just a string of zeros, but it did say some different models it was either zeros or 123.... Goodluck
As people found out from heleton these are useless
I for one dont care, the radio transmitts just fine I make a very good trip to different repeaters. I mostly use for monitoring purposes but in the event i need to transmitt it does the job. Just a normal guy not a radio dork.
Next time show the screen what we need to see it and reduce your own view .This split screen not good
ff6818 or bk4819 problem ?
Amazing video, I thank you very much, also a new subscriber. I just purchased this radio on Amazon, price is amazing. So I like the feature set but I wonder if mine will have the updated firmware. I will check when I get it. I enjoyed a ten year period as an advanced licensed ham operator. # KA4FLA which was so cool as I live in Florida . So with all the crazy stuff happening in the world I have become a casual prepper. The radios are for local malitia-esk coms when the SHTF. Certain neighbors will carry them. I keep all this microprocessor stuff in a faraday cage. I always want more power for longer range so I ordered the longer antenna 1/2 wave and I could put together an omnidirectional vertical antenna above my roof for extra range, no mountains or valleys around here, just flat as a pancake. Ten miles would work great for me, walkie talkie to base. Thanks again for the awesome video, I'm sure there are many who learned the "meat and potatoes" of this amazing radio. Ted in Sebastian, Fl.
Thanks for the comment! Sounds like you have a plan. :) 73!
So you are saying it's just fine if I'm just trying to listen?
Yes, perfectly fine for listening. :)
UV-21 PRO V2 is out do you plan to test that one?
Baofeng just slaps the UV-5R motherboard and the cheapest into a new case and calls it the UV-9R, UV-17 Pro, UV-82, UV-21R. Literally, there's no difference in all UV series dual-band ham radios (2m and 70cm). Just some minor battery, outer case, and display changes. Don't fall for this type of marketing. I've been a ham radio operator for 30-plus years, and I know these radios inside and out.
New guy here, loved the video ❤ great analysis, definitely helped me, I would also like to request a similar video on Quansheng UV-K5, K5(8)/K6, if possible off course. 73s de S21JDR
I'll try to put the Quansheng in for its own video. I have a couple more that are in line. Thank you so much for the comment and view. 73
