Just recieved this unit today, after purchasing it some weeks back in China, as it was so ludicrisly cheap, not least from a danish perspective., where everything is very pricey.. as both shipping and VAT +25% elevates it a lot. but 17 - US in total with VAT and shipping, seemed weirdly low, with incl. AC chargercradle, beltclip, typeC cable just seemed to cheap to pass on.. just did a wattage test on K5 146Mhz - High-mode peak 5.05W and settles around 4.99W (SWR1.01 dummyload) - Medium-mode peak 3.44W settles at 3.41W (SWR1.01 dummyload) - Low-mode peak 1.54 setttles at 1.52W (SWR1.01 dummyload) If anybody checked theirs at 146Mhz, would love to hear the values. Used Wattage & SWR tool surecom SW33+ with a 20W dummyload that came incl. (an wattage/SWT tool to around 30 to 35 bucks). The only other programable walkie i got is, the 8800+ which is way more expensive at around 55 US. thx for the hint abolut this software, could make these KV5 very popular

Easy way to jump into the 23cm band is put in 999.999 then hold the up button then at the same time press the down button and it will jump to 470, press the down button to jump down to 300 then again press the down button and it will jump to the top of the 23cm band, will show something like 2995, just the '1' missing. If you have it set on 25khz steps it's easy to go down to where you want . Save it in memory like normal and when you retrieve the frequency it works, save doing the procedure again. Getting it to jump bands by holding the up button as above but this time a press of the middle button on the left seems to do the same trick. Radio also TX on 925.5 which is our allocation. Don't expect much power out but it's a handy shack tool as a signal generator.

I would think you might want to turn down the RF Output Level on the TPI to something like -85dBm to verify it will receive well on a low level signal.

I think in past videos on Quansheng you mentioned many other names associated to it. For example availability here in the States it's easy to aquire a Anysecu radio which is identical to the Quasheng and to which I was able to perform one of the earlier hacks to unlock 220 band.BTW it's OK for receiving but not for transmitting , little to no pwer output. Nice little radio but tempted to try the Quansheng hacks just to see if workable for extended recieve like you have tried. I get the risks & may brick it but enjoy experimentation and radio was pretty inexpensive and cheaply enough to replace if I choose. I'll let ya know what happens down the page once I get to it !

[@lt4324]

Just FYI, I work 220 repeaters with no issue, full quiet, but of course depends on terrain and distance.

[@Spirit_Of_Prophecy_777]

The AnySecu is the radio I used for this firmware and it works. K5_26 top of the firmware update list. In case you are interested. Same radio. I have both Quansheng and AnySecu radios. TX on 54 MHz is usable on FM. Below that, and AM is poor audio, even receive. So, 50-54, 144-148, 220-225, 430-470 MHz. I have not tried 29 MHz FM audio yet. You'll need a resonant antenna, on other bands, or an antenna tuner that will tune QRP, or very low power, 1/4 watt, 250 milliwatts.

[@johnlannigan9831]

I mentioned elsewhere Gary that I use one of the sub $20 3 watt amps with mine and an adjustable attenuator to prevent overload. These amps need between 2 and 10mw drive to get 3 watts out. SO far I've had contacts on 11m, 10m 6m and 4m with good reports, we dont have 220MHz here in the UK.

[@Spirit_Of_Prophecy_777]

If you program 999.995, in the 5KHz step mode then use the arrow keys to scroll UP, it will take you down below the AM radio band 000.oo on the display. Not sure what the receive is down there. I am unable to receive AM radio from a local AM station at 1590 AM. The display does go there. Using the UP arrow left of the speaker, it takes you down to 000.oo on the display. Not sure how to get 1.3 GHz to program into the 6 digit plus 2 display, 999.995.oo. The firmware does work. Version K5_26 which is the latest firmware? AnySecu radio model UV-K5, same radio. So far tested, 28-30, 50-54, 144-148, 220-225, 430-470, 900 Mhz Ham bands and beyond. FM, TX and RX confirmed.

What is the difference between the encrypted 18 to 1300 bin and TX 50-850, AM 18-850 bin?

[@johnwest7993]

Displaying frequencies on the screen means pretty much nothing, even if the oscillators will oscillate on those frequencies. There are hardware LC filters built in, preselectors, (bandpass filters,) low-pass output filters, etc, that will block reception sensitivity and output signals on any frequency that is not among those designed into the radio. So on receive the radio will have 2 bandpass filters. Either one or the other will be switched in, period. The radio will be essentially deaf to any other band. On transmit there will be 2 low-pass filters, one for each band to filter out harmonic multiples above the transmit band. The radio will switch in one or the other, period. The transmit output stages themselves are tuned for those 2 bands, so their impedances will typically go to Hell very far outside those bands, so the chance of blowing them goes way up. Multi-band radios are expensive precisely due to having to add banks of the correct filters and impedance matching elements, and of course the switching for all of those bands. These frequency-opening mods aren't the magic mods and secret bands that are a joy to so many hackers and experimenters. They are simply detuning a radio so that it no longer works correctly. Playing with these parameters in these HT's is equivalent to tuning a car engine so that it operates well above red-line into a constricted exhaust system. Everything is just wrong. You don't get a race car. You get a blown-up engine or one that won't start. I'd suggest that if someone wants to experiment with multi-band mods they should start with an ADX type rig, some down-converter circuits, a bag of toroids and capacitors, a soldering iron, a NanoVNA, and a TinySA. That way actually works, and coincidentally is what hams are actually licensed to do, with the exception of transmitting on anything but a ham band.

[@noimnotarobotcanubeleiveit7024]

software mods preceed hardware mods these days. now we know the software can play nice we can poke around with the filters. maybe they can be bypassed then use a tuned filter on the antenna side to keep it legal. a mat-10 tuner taped to the back and a 5m whip might get kq2h on a good day?

[@BrekMartin]

Relax Nancy, it’s priced like the toy that it is. I mean really? This should be obvious to anyone who passed their exam.

[@BrekMartin]

Furthermore, you could quite legitimately bodge this radio and use it as an exciter. Tx low power, and do the filtering and PA yourself, or mix with an LO to convert for some other hardware. Not that I think anyone here cares about that, but it addresses the credibility of the mod.

Hey Hayden, Thanks a million for this video, my UV-K6 turned up yesterday, having used it for a couple of hours, I note a couple of things: It's easier to programme than my Baofeng UV-5R, without a programming cable I mean. I did buy a cable with the UV-K6, your video on the firmware upgrades was awesome, although it took a moment to get around downloading the firmware from GitHub, I've never had to do this before. The stock antenna makes the radio as deaf a a post, I changed it for another that I had and I could hear the local fire brigade of which I am a member, it was as clear as day! Not sure if I'm having a senior moment here, but in the programming software (with respect to 2m repeaters) it asks for the receive frequency and the transmit frequency, is that the radio end or the repeater it is asking for in either case? I stared at this for some time, thinking, what??? One final thing, in all of the frequencies I've programmed into this radio after the firmware upgrade, I still cannot TX on anything out of the usual 2m/70cm band plan, that is exactly what I wanted, I can RX but not TX.

[@HamRadioDX]

I’d recommend using Chirp mate to program - it’s much easier and better than the QS software (I wouldn’t recommend using it or installing it). When it asks for receive frequency it means the repeaters TX freq (i.e. the frequency the radio listens to). The opposite way around when it asks for transmit. I hope that helps

[@KapampanganReviewCollaboration]

Great video thank you

[@mmpiforall5913]

I would think to Tx on unlocked frequencies, original antenna SWR would be too high, change antenna to match band you want to transmit on. Test your antennas on a NanoVNA to see that they match your intended application. Lots of antennas I tested peak off band! Lots of SWR and low range in band!

Same problem here. Haven't found a solution for this.

[@damiengirvan5020]

So with this mod I could listen to CB radio and pmr446 in the UK? And there is a transmission mod?

[@HamRadioDX]

Nah, the TX won't stretch that far... hardware limitations then.

[@damiengirvan5020]

@@HamRadioDX so what can the tx mod do?

[@damiengirvan5020]

Ware do you download that program portable radio tools?

[@rosie9490]

I would love to have that great RSSI and extra backlight time but not at the expense of loosing half the output power on 446 Mhz. It seems that not as much is lost on 433 Mhz.

[@NicksStuff]

That's in RX only? I'm a pilot and having a backup radio would be a plus in case of an emergency

[@byMarto_com]

Im curious about that limitation of the chip so it can't transmit from 630 to 840MHz

[@rickadkins865]

I bought one of these radios, but try as I might, I cannot get the firmware mod to update the radio. It keeps telling me the update failed, or it's not compatible, or whatever. *Nothing* seems to work. Any suggestions? I'm just trying to get the extended reception on the radio. I'm trying to load the Tunas1337 mod as shown on your vid. Thanks.....

Is it possible to unlock the frequencies of 50,000 mghto talk on the quansheng uv-6k?

[@Wesley-WSEL-698]

What trunked radio system has an analog voice that ou can hear that? is that an LTR system that you tuned into?

[@HamRadioDX]

We had an analog trunk system with digital control channels... analog voice was on it and shifted frequencies between talkgroups.

[@kd5yut]

I wonder how frequency agile it is and what the sensitivity is at 18mhz

[@handlebullshit]

Probably shit

[@g4wwk-k2f]

100watts at 18MHz connected to the aerial socket should open the squelch?

[@chichia6159]

perdona macho y gracias por los videos . una cosa , ya lo hice pero no me deja transmitir solo recibir . en cb . podias ayudarme . ?

[@anthonyabel8863]

Will this firmware update allow AM receive in the 300mHz range?

i need help to install the usb driver i get a error about the language is not recognized by the system or something

[@chilly_willy_allentech8328]

is there a moble/base non hh upgrade biger radio to this radio or oters like this ??? like GMRS-50X1 and UV-50X2 and TYT TH-9800D Plus

I have an error for install the drivers. Error: The current language is not supported by the Device Driver Installation Wizard. Can u help me?

[@sdram7395]

Hello ! I have a problem with my radio. When I click on update an error message appears. It says "update program failed!". Since, I can no longer turn on my radio. When I turn the knob, nothing is displayed on the screen.

[@mmpiforall5913]

what firmware did you load?

[@whoisme678]

Now is the software availability intentional or not ?

[@itrstt66]

did you figure out out to change the frequencies?

[@laurentsetzer7094]

Very good video !!!

[@mmpiforall5913]

I ordered 2 K5 radios, hand mics and programming cable from same seller. Programming cable and CD say "Baofeng" (actually looks like "a/\OFENG") is it OK to use for firmware update? Also which Windows Version is BAD for this upload task? I'm reading there's a few bricked radios out there, but no reasons given. TY!!

[@jimcombs6760]

what do i need to do to allow my pc to open a bin file? it tells me i need to download a file to open but i dont know what file to download to open the bin file? sorry, im old!

[@mikeZL3XD7029]

Thanks Hayden, I bought one of these radios on eBay (sorry Amazon had none at the time), but I looked at the sale email and apparently I had bought a UV-K6?, it won't make it here until April. Is this a thing?, I was not aware of this model, have I been sold something different or is this a typo? Thanks for the upgrade info though, it's awesome.

[@HamRadioDX]

Hey mate. The UV-K6 is basically the same as a UV-K5 except a different speaker (apparently) and faceplate on the front of the radio.

[@ravyyyyyyy]

I have the latest firmware on my radio and it doesnt seem to be letting me flash the modded fw, tried the 1.19 and 1.26 versions, when i connect my radio and choose the file the update button remains greyed out, has anyone experienced this? I'm guessing the program only lets you update to a newer version and not overwrite or downgrade, is there any other way to do this?

[@HamRadioDX]

Check out this video - kzbin.info/www/bejne/o2TdiXuVlKeFhq8

[@Cheordig]

When I click update I get an error message saying "the length of the file is too much."

[@jcramond73]

Tried everything to get my windows 11 pc to connect to this radio, but no go, first it doesn't support the 2303ta ucb baofeng cable, then doesn't recognise it under the prolific usb to serial com port and unable to do the browser flash either. Not having a good run, anybody know another way?

[@harveydeniropresley]

How high do you turn the volume control up when going in to boot.update mode ? because it's not communicating with radio using CPS software.

[@HamRadioDX]

Just "on"... Hold the PTT, turn the volume knob and the LED light on the top comes on... plug in the programming cable and the TX/RX LED changes to blue. Then you should be good to program.

[@harveydeniropresley]

Yep, got that thanks,.all modded now and the Air band is super clear. With the stock firmware it was terrible.

[@daKnighty]

Does the firmware work with the quansheng uv-k5(99)?

[@funeflicks]

the link doesn't download it keeps opening a new window

[@MorrWorm8]

Do you need chirp to download the firmware? I’m a total noob at radios. Should I just stick with the stock firmware?

[@jannierossouw7533]

What program are you using there? (TPI Link)

[@andrevitor4576]

Eo baufeng 17 pro tem como desbloquear também? TKS Fort 73 de PU2VOS André. Tks

[@Joe64-E30]

Thanks, works perfek! But how is it possible to manage the new frequencys in CHIRP? CHIRP doesnt save this "illegal" frequencys

[@DjPaNik]

Ok but what antenna do you need to listen to 18-1300Mhz? The default antenna that comes with the radio is not capable of that I believe.

[@Nick_G7IZR]

Is the low power on 6m and 10m (and 4m) due to the mismatched antenna and the amp throttling back or were those results in to a 50 ohm load?

[@HamRadioDX]

Power level still to be tested on the service monitor but I suspect the results published are because the PA unit in the radio is not that broadbanded enough.

[@noimnotarobotcanubeleiveit7024]

@@HamRadioDX poke inside and play with the coils?

[@BobCarterMidAtlanticEngineer]

I suspect the low power and multiple harmonics on other bands are due to the band pass filters in the radio that are designed for 144/444mhz will not pass and filter the RF outside of those bands properly. I suppose one could bypass the internal filtering and come up with your own filtering on a small PCB and screw it in at the antenna terminal and then connect your antenna to the other side of your fabricated LP/HP filter. You would have to build a filter and change it out with every band that you wanted to operate on. The other limiting factor is the electrical characteristics of the PA transistor in the HT....will it actually produce one watt or better on the other amateur bands. That will take some investigating, which I'm sure someone is already experimenting with that part of the radio.

[@DonzLockz]

Holy crapola, im gonna have to try that as I now have two k5's. I just want the extra receive.👍🍻🤠

[@HamRadioDX]

Update the firmware at your own risk 😉 I need to test sensitivity

OOoooo Yeaaaaaah

Hi Thank for those explanation. Do you know if there is a firmware update for macos ?
