Great video, the answer to your doubts (track 2:10) is "200 Channel memory" bro. The item you got here is the same exact variant of the QYT 25 Watts 2 Way radio models, and the model you got here is a QYT KT-7900D, I know it from the buttons, they almost look like the QYT KT-8900D model but the buttons are different, this one is a KT-7900D variant which also has a 200 Channels memory.
In the Philippines we have the SRRS around 325mhz. (Equivalent to FRS and allocated for license free radios)
Start video... wow, nice radio... giant hand enters frame... holy crap that's a small radio!!!
I have the brand x version of this radio. Bought it mainly for its 220 ability. It worked great on 220 for two months ,then slowly lost receive. rebooted and reprogramed and it worked for a day. Right now I use it on a linked system for transmit and have to listen to it on the 2 meter side.
That worked! I had to use my old W7 laptop for the COM port to connect to the radio. Thank you!
Looks exactly like the Btech mini UV 25x4
Thank you for posting this radio. I got one and it works and sounds great. I thought this radio had quad monitor so you can listen to more than one repeater or frequency. Mine does not and I hope I can find a way to listen to more than one frequency. Most radioes like this can move to any frequency in use.
I have the QYT 7900D version, it monitors all the channels you program into the screen...at least mine does...can't hear anything on mine anymore only lasted 2 years and has already failed won't be getting a replacement radio, lost interest in amateur radio completely.
In the United States of America, the US Military (US Government) operate from 225 Mhz to 400 Mhz. The majority of that is Military aircraft communications in the AM mode. But around 370-390mhz there are a lot of military bases that have P25 trunked radio systems operating. There are no civilian, personal or license free freqs in that band, so like you mentioned, for US hams it's a more of a tri-bander radio.
Thanks k you I have been looking at the qyt version for my truck
I have the QYT 7900D. I thought it was a great radio but of course you get what you pay for mine has already died (lost audio completely) after only 2 years of very light occasional use, not impressed. Won't be replacing the radio with anything else, nothing I really need one for in the first place.
Save your money buy a brand name radio like Yaesu, Kenwood, ICOM, etc. Skip these cheap Chinese piece of shit radios, they will quickly ruin your amateur radio interest because they don't work very well and don't last long.
awe man i really want this radio!!! and its priced right and everything!
Mine came yesterday, within 15 minutes of use and it's dead.
North Woods like a robot
same as QB25. 220 seems to be a seperate internal amp thus the clicking when a 220 freq is in a memory. not the best squelch. perfect for new operarors like me.
its always full of hash on recieved signals on 220 = static
Just ordered one. liking what im seeing thanks for the vid. 73..
I'm looking to small. And as you said a size about the size of a slice of bread will work great in these newer cars with not much to any room for mounting. I'm going to get one of these and will be mounted in my small cubby hole in front of my auto shifter. 4 bands under $100.00 I like. Hope it's not to bad to program with software. Thanks for your review 73 George KI4NBE
Don't waste your money.
There are some Personal Radio Service en.wikipedia.org/wiki/Personal_radio_service frequencies in the 350Mhz range. Wonder if that's related.
Why can't Kenwood make a quad 220,440,6, 1.2 I would buy it.
I have found that many of these Chinese radios have poor receivers. In addition overall receiver noise and squelch performance is poor as well. Showing power out good of course. I would recommend spending more time on receiver performance sensitivity on each band with a service monitor. Nice demo of the features. Thanks for the Video.
sensitivity is published in the manuals. i've got a bunch of expensive yaesu and expensive fancy icom and the chinese stuff holds up well. i also have a rohde & schwarz spectrum analyzer to verify FCC compliance... the cheap chinese stuff passes.
Very good! It would be nice to see the receiver performance demonstrated on a commercial service monitor.
The power out isn't that great either, at least not on the intended frequency you are transmitting on. It will look good on an ordinary power/SWR meter, but when viewed on a spectrum analyzer, about 25% of the power is on spurs and the second and third harmonics!
Found this about the Baofeng UV-5R, it transmits way better than receives; products like Wouxun are better. Especifically in 5R, disabling TDR, disabling save mode and reconfiguring squelch levels as an exponential series via CHiRP improves things a lot. But yeah, a radio with analog front-end, Chinese or not, is better at reception.
@@TMS5100 or just because its Chinese right
Unboxing video is so 2012. Made me laugh. Good one. 73
Sure, but a few unanswer steps.
How to determine appropriate firmware to use. I have something called "MS9" It is slow. I would like to get rid of all the memory wasting stuff and just load KODI on boot. Mine came with a full OS. I dunno if its 32 or 64bit, max mem, cpu, etc.
What specs do we need to know and how find them?
Then what, where, to find.
EXACT same mic on the new BTech 50 watt mobile, too.
mic resemblesres Kenwood commercial mic I have on a tk-862g uhf but has DTMF .
Great for a small car (I have a truck LOL) thanks for the review, well done.
Very good 👍 review, thanks
good review. I have two Yaesu quad band HTs and use the heck out of them and love the 1.25m band mostly. Unfortunately none , as far as I know, the main Japanese mobile radios do not support 1.25m. Please let me know if I am incorrect in that statement. This has the 1.25m 220mhz I have been searching for to use in my Jeep as a base station connected to a Diamond tri-band antenna. Excellent review and will try it out. Thank you !
You said you had a vid on that bluetooth mic... I cant find it... WANT...!!
Great video & amazing intro
Thanks for the video. these sets do require some knowledge and study, and some trial and error. That mike looks a lot like the stock one on my Kenwood TM281, the buttons are a little turned around. I have the luiton LT 898UV and the stock mike was no good so I bought a Kenwood style knockoff mike that has no keypad. The sound quality reports I get are much more favorable.
you may have had an answer on this - but the 350 mhz band is part of the mil band -
good review thinkin bout buying one for a go box for ares
This unit is no longer ava.. does anyone know what the new models are? very interested
Radioddity has the QB25. Same radio.
looks interesting , however seems like the Chinese radios don't seem to last very long. but as you said for a "go box" may be worth the price.
I wouldn't recommend wasting money on one of these or any of the other knock off's. Buy a brand name radio or don't buy at all. I have the QYT version it has already died after only 2 years of light use. They are junk. You get what you pay for a pile of trash.
yeah because its Chinese, we get it
i have the dual band version of this radio. the programming software leaves a lot to be desired but the radio works just fine.
Put up a 300MHz repeater up for your own red dawn repeater
looks just like the qyt TK series
I'm pretty sure this exact radio is sold as a Radioddity QB25.
I got a practically unused one for very little, and I'm planning on using it to set up a 1.25m repeater.
What kind of power supply do you recommend for use as a base station?
Great Video! I'm looking for a radio for Packet service into a TNC-X, would this work with the correct cable from the Microphone jack? Thanks,

350.000 I belive is or was a military frequency.
And police in Lithuania.
How does this compare to the Baofeng UV-25X4 or the QYT KT-7900D? Which one is the best?
Also, does this support cross-band repeat and simultaneous receiving of multiple bands, are the VFO's completely independent? For example, on the UV-5R the radio can only receive on one VFO at at a time, not on both simultaneously.
Also, are the VFO's locked to one band only, in other words can you set more than one VFO to the same band, like have 4 different 2-meter frequencies at once or 4 different 70cm frequencies at once, or does each VFO have to be a separate band?
hmmm.... There is a chance that the 350Mhz band is MIL comms in Europe. It IS locally.
GreekPreparedness Im from Bulgaria and one taxi driver told me some taxi was on 390 something ,so parts of 300mhz are free to pay for and use. I hear two firms on 147.625 and 147.175 where I am the other ones use 50mhz and some are with tablets and internet.
Im not sure how many firms will use unproven chinese radio through for busines use
That is called "Freebanding" and is illegal. Just because the frequency isn't busy in the area doesn't mean it is yours. I heard of a taxi company in the Untied States that got busted big time because they were using 2 meter ham frequencies so they wouldn't have to pay for a license from the FCC (it is illegal to use ham frequencies for business use). The cost of the fine was a lot higher then a license would have cost them.
Amazon lists it as "Dual band transmission" ,"4 Band receiving", "4 band standby" I see yours in the video does transmit on 4 bands. Seems a gamble the way it's listed on Amazon as to if you'll get one that transmits on all 4 bands.
Mine came yesterday, within 15 minutes of use and it's dead.
@@CityToTheWoods Yeah they're not very good.
Hi Eric,
Have you ever tried the Seesii PROTEC SP7200 Tri-band antenna? Suggestions greatly appreciated.
73 DE K5VPC - Jorge
Spring, TX
Havent figured something out about this radio. It seems to be auto intuitive as to whether a repeater is + or - and which offset is needed. HOWEVER....if you actually turn on the + or - and attempt to set the offset....well, it stops working. So ive been a bit perplexed as to how this is working then. Ive hit 4 local repeaters with no issues, but how is that possible if it isnt showing a proper offset?
Great Video! Would this radio be a candidate for use with Packet Radio, as it needs to be a clean a signal as possible?
No data ports for clean audio in and out which os what packet needs. This will not fit the bill
Can you show the power supply for this that connects to household power outlet? thanks
I did, search MFJ-4245MV
I have the Btech version, is the internals the same on both radios. They look the same on the outside, just different stickers.
Are there a way to change the model number at the bottom of the screen to your callsign?
I use Chirp and programmed the display on start up and I believe the bottom display. Don't remember if I put my call sign or name.
But why is your SWR so high into a dummy load? That throws off your power output measurements. With no disrespect intended if you want an accurate reading you use a Bird wattmeter with the appropriate slug and a 50 ohm Sinclair or equivalent dummy load.
Would have been better off using the 200 watt setting.
JustAnotherGuy if I had donations for all the extra gear I certainly would have that..
HamRadioConcepts :: I understand and I did not wish to sound ungrateful for the time and effort that you put into your reviews. It was just natural as an extra class especially to see above-average SWR indicating an incorrect power level. The fact that you were showing 17 Watts was because your SWR was high. At a minimum perhaps you could get a can dummy load. They are inexpensive and will give you generally a wonder One SWR up into the 440 band. You fill them with mineral oil. My way of testing is as I described. Generally on two meters you use a 2-foot interconnecting cable to your SWR bridge that should have a terminating load directly attached to it. You pick them up on eBay inexpensively. But that's okay. People get the idea. I'm amazed that this radio is so small and I'm concerned and puzzled that it got an FCC type acceptance when it covers the 350 disk 90 megahertz band when that is not an authorized fan for amateur or commercial.
I like it is there ONE that has 50w on all 3 bands for us..bc I want a good high power.
I figured that I'd give it a shot. Within 15 minutes it was dead, need I say more??
Really?
Yes, really. Sending it back tomorrow. The display started flashing then it took its last breath.
There is "ONE" review on Amazon, guess who it's from?
www.amazon.com/LT-425UV-Transmission-Receiving-Standby-LUITON/dp/B06WWBTLV4/ref=sr_1_1?ie=UTF8&qid=1495329078&sr=8-1&keywords=luiton+lt-425uv
My QYT version died after 2 years, well it still turns on but the audio is gone, no audio output at all anymore so you can't hear anything. You get what you pay for LOL. Definitely don't recommend them, I'm surprised my Baofeng handheld still works LOL. They're junk, don't waste your money. Buy brand name or don't bother, at least with Yaesu, Kenwood, etc. you may have some luck getting parts and help repairing any problems that may arise.
perfect
can it transmit at 1.25m and 350mhz band too unlike RX only like the newer 8900D? NICE
Can I use on a boat for VHF coast guard .
Great video thanks ..
1# How many memory channels for radio128 ?
2# Of someone's on 146.655 talking & another party is on 444.500 at same time does radio receive both signal vs the first that transmitted or it just received highlighted band ? TY 73's
You can only hear 1 channel at a time. Whichever channel transmits first is the one you are going to hear.
If you get a chance to try it on a tyt9800, would you please let us know. My radio came with a low audio mic.
Specs say only TWO band transmit. Four band in receive only. Were you able to transmit on 220?
Does this model, can you also Tx and Rcv on GMRS channels, suppose you need to put them in.
I have the new version of this... I like it $49
Homefront is it a good tech radio for amateurs just starting out
Charles Dan weirdo too The Truth? No, the menu system is a bit retarded. But if you are a quick learner its ok. Id probably get a used Yaseu 2 mtr as my first radio, BUT for $50 this radio surevis fun to play with and I love the performance.. Boy was I suprised.
Hi. Which kind of new version you have please? Where did you bought please?
which is the new version ? can you link it pls. thx :)
The 350-390 MHz is used for United States Military operations, if you transmit there you will likely meet the FCC real quick!
In the USA if spectrum is used by the armed forces than it is their jurisdiction and not the FCC's. This makes it doubly worse.
Can you change the 350 to something other,like first and second row on 2m and the third and fourth on 70cm.
P.s. Can you do european power checks if its not bothering you (145mhz and 435mhz )
Hey, I'm getting into ham radios and I have this one, do you have any good sources that explain the purpose of the 4 bands? And the purpose of differing between uhf and vhf?
Bad swr or voltage or Watt meter, i have 35W on 220m with 13.8V
Can program these from the radio ? Without PC ?
Eric I just got my Ham License Technician Class this Luiton LT 425 is perfect for some who just got there Technician License
It cover all the bands I can legally use Amazon is out is there any where else I can look for a Luiton? Let me know Its Victor
How do you get it to display the Freq + Channel Name
I’m new to the HAM world, just got my license. I have my eye on two mobile radios, the BTECH Mini UV-25X4 25 Watt Tri-Band Base, Mobile Radio and the BTECH Mini UV-25X2 25 Watt Dual Band Base, Mobile Radio. What’s the difference between the two? Which one do you think will suit my needs as a new licensed HAM operator?
Don't waste your time, wait save the money and buy a brand name radio, these no-name Chinese radios give very lackluster results in both transmissions and lifespan. They'll just die or not work and there's no support for them at all, and the FCC actually says these Chinese radios are illegal to transmit on anyways, and its no wonder with the horrible quality they are, but the reason being is they can transmit on frequencies that aren't amateur radio frequencies but at the same time you as the owner/operator of the radio it is your responsibility to know what frequencies you are allowed to use.
The sound of the relays clicking when you change bands is the low pass filters being changed.
Your power measurements are somewhat useless as the swr is pretty high...... You would need to subtract the reverse power from the forward power to give you net power.
I have one, does great.BUT, how do you program it? the one I have came with a manual, but NOTHING was said on how to program it. so what good is it?
down load the program see google
So this radio doesnt have channels where you can save on ? does it have naming ? ---------- love this channel. im like a kid in a candy store LMAO
Anyone know how to Mars mod this radio?
how far can you reach a buddy with the same radio
Qual a antena indicada para esse radio?
Can this thing be used with echolink?
Nice. I have a similar radio on my channel.
I can't seem to find if it does DPL, can you assist?
Don’t forget to check harmonics
Aren't the 220mhz band and the 1.25m band the same?
Yea
В низу дисплея это S-METR ???? СПАСИБО.
How easy is it to program by hand for people like myself who don’t have a computer?
I just select the channel I want to use and input it into the A/B/C/D bank that shows on the screen...at least that's how I did mine not sure if these newer ones are the same but you hit the channel selector A/B/C/D till the arrow is pointing at that channel then just enter the frequency then go to the next one and enter a frequency, no programming needed. The menu is a really useless thing as it is with most radios unless you figure out the abbreviations and sub-menus which the book explains, and if you do repeater work, you'll definitely need to know the menus and sub-menus to be able to enter the offsets, tones, etc.
I have the QYT version of the radio in the video and after 2 years mine has lost all audio, not impressed, but you get what you pay for, buy a cheap pile of shit radio you get a very short lifespan and terrible transmissions at times. I don't recommend these radios, and the FCC doesn't either. Save your money and buy a known brand such as ICOM, Kenwood, Yaesu, etc. skip these cheap Chinese radios.
@@wildbill23c thanks, sorry but I’m just seeing this after two years, I ended up buying the yaesu ft300, been happy with it.
17 + watts reflected error
can this radio transmit on 220 mhz freq ?
220-260 mhz
Oklahoma HamRadio Geez mine can transmit damn near anywhere.... lol
Muito bon
Your meter needs calibrating since it is NOT sitting on ZERO where it should be but of course it is made by MFJ aka:My First Job.
1OFGODSOWN I did adjust it its on zero now
my radio is dead over heat causes...
Yep, mine would overheat without being used, and now has lost all audio. Only 2 years of very light use and its already dead...don't waste your money on these pieces of shit.
Hey Bro Where do I get a Luiton -425 UV I want to buy one
Radioditty QP25 or QB25 on eBay. 100$
Sorry nug when SWR is not 1:1 then your power meter does not shows correct power.
hooo - waah , I love cheap radio's . like toys for big boyz. keep it up sir ! 73s de KE0NAZ...
They're basically disposable radios. I run these cheap radios in my Jeep, which rarely has the top on. If it gets wet or stolen, no big deal.
Can it transmit in the 150 bands
project desert chaos yes
Just bought 1, Got it 07/01/18 and tried to program it with Chirp, couldn't get it to write.Did not work. I used the supplied software on the disk that came with the radio and it worked PERFECT, Easy to program with it. I do have to this radio is BAD AS_ I will buy 2 more for my other truck and car. Will do update later.
i programed mine with chirp. just make sure you have the right driver installed. chirp was way easier, just cut and paste. at least it worked for me :)
Thanks for a great review of that radio. I just acquired one from a recent silent key. I got the radio, power cord, mic and the programming cable. I went to Luiton website and downloaded the drivers and software they have on site, but what I was looking for was a PDF of the owners manual. I have done a google search and just can't seem to find one. Do you know how I could get a copy of a manual??? Thanks in advance. I have sub'd to your channel. The name here is Juddie and my call is WD8WV. Email good in QRZ.com
1.5 SWR your not getting that power out
Its technically illegal for I to operate this radio but I can own it and listen to different bands.
Technically any radio is illegal to transmit on if you do not have the proper license to do so, and you are not using a frequency that is authorized by the FCC as an amateur radio frequency, some are only secondary frequencies, some only allow for morse code, etc. It is you as the owner/operator of the radio to know what channels you can transmit on within the limits of your license. Doesn't matter what brand the radio is, they are all capable of operating on non-amateur radio frequencies in some aspect...its up to you to know those frequencies and not to use them, or not transmit on them, you can listen but not transmit on frequencies not allowed amateur radio traffic.
I have had nothing but grief with the cheap Chinese radios. Every one has died over the years. I willspend more for name brand and/or converted Motorola or Kenwood before I will buy any of these. JMO !!
Ok boomer!
well, Paul, just bad luck...I have excellent radios, amps, tuners, etc in the shack, and great radios in the truck...I also have two bafueng hts and this new radio.....why people keep crapping on them is beyond me.....I personally do NOT know one person whose radio has crapped out on them....ALMOST ALL OF THE PROBLEMS IS WITH THE OWNER NOT COMPREHENDING THE PROGRAMMING. I KNOW IT SUCKS BUT THERE IS PLENTY OF INFO ON YOU TUBE....AND CHIRP IS FREE! THESE CHINESE RADIOS WORK GREAT.
What job in Jackson TN do you have that you can afford all these radios LOL
Jarred Jones never lived in TN in my entire life.
aww misheard the call. :) ok florida lol
Im guessing by the looks of it its a straight fm radio.
berapa duit bang...
Can this work as a repeater?
220 is VHF lol
Interesting radio, but I wish you could show it operating mobile. My experience with both Baofeng and Leixen radios is that they work great...until your car starts moving. That's when the quality of their receivers becomes suspect in my experience. They all perform great standing still, but they're meant to be mobile radios and hardly anyone on UA-cam tests them that way.
Mine came yesterday, within 15 minutes of use and it's dead.
North Woods 👌🏽
At first you did not made nullinv of cross needles, second the power is correct on scale only into 50 Ohms ! On 1,4:1 SWR the scale does work and meter is nog showing correct power!
Power measurement with so high SWR is completely inaccurate! Power meter shows correctly only into proper matched load... this your test says nothing.
Forward power is forward power. He is going into a dummy load at that point I believe.
@@johnlagreca6288 Simply not! Please read some basic physics. The power is detected by power meter wrongly (inaccurate value indicated) as it is not matched properly... If you will load it with different impedance then you will read different power on the meter > think about it why?
Yes Petr, of course as the watt meter is most likely measuring by E^2/R and assuming R=50. The question really is if we are going into a purely resistive 50 Ohm dummy load why are we seeing reflected power.
I am not familiar with the tool used here, but it appears the SWR is around 1.3-1.4:1. At 20 watts this would be about 0.5 watts reflected power which I don't see as a large factor in the power measurements reported in the video.
We are not splitting hairs here, we are just trying to see if the output power is close to the manufacturer specifications. To say "your test says nothing" because of 2% error is quite an overstatement.
These radio's are junk
