I have refreshed the firmware of the 18-1800 transmission version, but it still cannot transmit in the aviation frequency band 118-136. The receiver cannot receive sound, but there is a prompt on the screen and the green light will also be on. May I ask how to solve it? Does the hardware need to be modified?
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
@@HamRadioDX Can I do the same on the 5r plus?
Nelzya in Russian means disallowed ) SWR in this radio (factory antenna) is good at 145 and 430 so it is no surpise you can hear airband which is slightly below. With tuned antenna or wideband antenna like from those rtl sdrs you will be able to hear much more. What a great model they made!
I think it's worth mentioning that two other very talented people worked on the firmwares and collaborated together with Andrej (Tunas1337) on making these possible. I can't wait to see what else the three of them achieve together, and I hope more people join their efforts!
Hopefully they will do the QuanSheng UV-5R firmware as well. I tried to upload it and it gives an error.
THANKS ! THANKS TO THESE GUYS! Seriously, Moznja Ilji Nelzya, I Love Them !
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.
This works great and i have RX now on 23cms as well..
thanks..
First!
I found that firmware page yesterday, that's a whole rabbit hole to go down, isn't it? I've got my K5 hooked up with the AIOC board and a pi running direwolf at the moment. Apparently, I'm gonna have to tinker with new firmwares in the next couple of days. Good job, mate!
Nice! Yeah I chucked it on quickly this afternoon. I still don’t know how to manually input frequencies above 1 GHz without it selecting a lower band. Also need to do sensitivity tests
Ahhh!!! You made me order another radio! Since none of my DMR radios can receive in AM mode, or even operate in 108-136 Mhz, I had no choice! Darn You! 😁
Glad I could help!
108 to 117.975Mhz is aircraft VOR beacons, aircraft coms is 118.000 and up.
Thanks for showing me this awesome hack, much appreciated. My UV-K5(8) model works on all bands including CB in AM & FM.
Glad to help. Thanks for the Super Thanks too!
What did you install this firmware from the video?
@@psiho_051 No i gambled with the new model UV-K6 with a custom firmware tested on the older UV-K5. The firmware is available on a different site.

Thanks for this video!!! I have installed the 18 to 1300Mhz bin file and it workd like a charm. Have to do some more testing tomorrow, but so far it looks good.
I think it said 1300 Mhz.

Which diode?
Or snip the green wire .. lol

@@redbluff2583 Icoms
Amazing, just what I was looking for! Thank you so much!
Awesome Hayden. Very cool seeing my handle listed as a new member. 😀
someone needs to add a trunking mod to the UV-K5 . ;)
Also, when you punched in 1000 MHz on the TPI, you could click the Modulation tab and punch in a 1Khz FM tone with modulation level set to 20% or so. That way you could hear it on the UV-K5. ;)
and..... 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. Right now at your -40dBm level youre not really making sure there arent issues with the Front End of radio in hearing weak signals. 👌
Thanks you again for being a member!
Yeah I just threw it on quickly and I was preoccupied with trying to get it working on 1.2 GHz to see how it is on the ham band. I'll need to do some further sensitivity testing later. Once I can work out how to actually get up to 1.2 gig in the radio
Great mod to radio. I found that on uk 6m & 4m bands second harmonic was higher than fundamental frequency. Also found that TX worked on air band. Looks like pa stage filters are only for 2m & 70cm. Good fun but have put standard firmware back as don't want jets falling out of sky. 73s G8GRL
i bet a small transmitting loop woul get those harmonics back in line.
VHF 118-136? or ads-b 1090M?
TX in AM?
@@david_ropes yes. not great but legible and definate not fm
Nice to hear that! Which soft exactly unlocks the TX in the air band? I fly a glider, so sometimes I need a backup radio.
Bought a K6 as well, hacked firmware works fine on it.
Firmware works great on mine, no issues thanks to all creators!
Installed new firmware now, and done some initial testing. It does receive, but sensetivity on lower frequencies (under +/-70Mhz) is not great. Its is noisy all over the spectrum as I can see if you transmit. But still fun to play with and see what it can do, I am still surprised that it works
what cable did you use? mine doenst work
@@pe1owg439 i used the ordinary programming cable. Remember to hold ptt while you turn on radio to be able to update
@@pe1owg439 If you have that Baofeng usb-to-headphone mic jacks, try to push it harder to the body of uv-k5. And be sure you have unzipped the uv-k5 usb-driver file. That was resolution of mistakes I initialy made,..
Ware do you download that portable radio tools program?
@@damiengirvan5020 Regular Quansheng site. After you unzip uodate you must unzip driver setaretly program which is part of update.
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.
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?
Relax Nancy, it’s priced like the toy that it is. I mean really? This should be obvious to anyone who passed their exam.
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.
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 !
Just FYI, I work 220 repeaters with no issue, full quiet, but of course depends on terrain and distance.
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.
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.
Bout time somebody made a video on this... 😂
Thanks to you it was all possible 👍
very cool. i was already impressed by this radio as standard, but now i am super impressed 👍👍👍👍
Even if you can’t transmit on a lot of the frequencies, for someone that doesn’t transmit, like myself, that would be perfect.
I'm really new to this, never owned one before but I intend on listening and learning. What would you recommend I do first when it arrives?
When you PTT at 850.0 - NELZYA - is Russian for - “not allowed”
Ahhh thank you!
Oh of course it's Russian for not allowed haha
Sorry, I was playing around with the strings as a joke! That one made it past the publishing filter. - Andrej
Can’t you go into hidden menu and turn that off? Maybe....😉
What is the difference between the encrypted 18 to 1300 bin and TX 50-850, AM 18-850 bin?
Great video thank you
Nice, it even worked on my Anysecu UV-k5. Thanks much.
Hello. Is there already a modified programming software to save the frequencies?
Chirp ?
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!
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.
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
The list of the output powers you mention at 10:02 are the levels of the harmonics if you transmit with 27.254MHz i think.
@@MrKeys57 what did you have to change to get it fixed
@@MrKeys57i hate people that dont tell HOW they fixed it
@@TheBbarrow79 the upgrade is on Girhub, user Fiagci
its working with mine, can tx on fm broadcast band in fm or am, can just about tx cb27 but slight offset. above 1ghz the first 1 is ommitted from display. delivers tx into dummy load for am airband!
almost as good as my vx7r, if only it did sideband, eh?
if quansheng play smart they will play on the marketing generated by the hacker community.
there should be a new version of chirp for it soon. work is in progress
Really? All this works? I want to cover UK CB am and fm and pmr446.... And I'd like it to tx in an emergency.... But I was told it wasn't possible....
Awesome video!!! When the frequencies are unlocked does the radio receive and send a signal on all frequencies or can it only receive a signal?
Thanks in advance!
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. The system on a chip provides from DC to daylight, the circuitry of the radio does not support the entire HF bands below 18 MHz. Thank you. 73'
Holy crapola, im gonna have to try that as I now have two k5's. I just want the extra receive.👍🍻🤠
Update the firmware at your own risk 😉
I need to test sensitivity
But what about antennas?
I'm guessing with a beefy antenna it would improve Reception?
EDIT *_Subscribed & Liked too!_*
Thanks!
This is great stuff:) I love to modify things:)
where do you download portable radio update tools (v1.1.12)?
Just because the software can go down to 18 MHz doesnt mean that the hardware is sensitive there.
I Guess you like the post I put in discord it works great
I didn't see your post in Discord? Where was it?
Also congrats on getting to 2 years as a member!
I ordered it ! ...before it sells out!
@Ham Radio DX , do you know a programsoftware to upload the Bin file firmware from a Linux Mint computer to the Quansheng?
I searched on Google but i can´t find it.
OOoooo Yeaaaaaah
Update, Attempted to upload the hacked UV-K5 firmware to the QuanSheng UV-5R, it gives an error and says the filename does not match. So, no go on the QuanSheng UV-5R, to UV-K5 hacked firmware update. It will program with the QuanSheng 1.38 programming software and takes a codeplug from the UV-K5 as well. Wonder if the Google chrome online firmware upload version will bypass that error? Anyone willing to give it a try and post results here would be appreciated. Thanks 73'
Did you mean QuanSheng UV-5R Plus?
@@VideobyRenta Yes, the name badge does say UV-5R Plus on the bottom of the radio. Was only aware of 1 model UV-5R from QuanSheng.
Sounds like Edacs Control Channel, me gusta mucho :D
Ahh yes :)
Even if they hack the firmware the internals only work with certain frequencies, sometimes you can hear or transmit on resonant frequencies.
Be interesting to see what the sensitivity level is on 10m fm with the sig gen
I betcha it is lower than whale crap. Lol
with a short whip i can get am broadcast stations around 19-22mhz. i need to get a second one to tear down and see if there ae filters that can be bypassed/switched/tweaked.
its only the tuned components that stop the full 5w on most frequencies to tx, they no doubt present a problem on rx.
it may be possible to add some latch relays to add a bypass for rx, and a choice of inductors for the output filters on tx
@@jstrunck I bet you are right!
Very good video !!!
Now I'm extra happy I just bought this radio. Thanks man. Brilliant video.
I bought one of these because of you. I wish I would have bought multiple so I can experiment on them and not run on the risk of damaging my only radio. I'm worried future models are going to be limited and locked down
Baofeng just went out of business 😲
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!!
Is there a way to open the radio up to transmit on Airbands? I know it wouldn't be legal but it would be great for emergency use if lost and you happened to see search aircraft looking for you.
You should be able to pick up an old but good Icom IC A2, etc for $50 to $100
it wont be 8.33k legal but most important Air channels are still on 25k steps
The UV-5K will receive AM, but its hardware cannot transmit AM, only FM. You might break their squelch, but FM coming into an AM receiver will likely be too distorted to copy.
@@paulplack490 You must never have tried slope detection of FM?
Tx on airband requires finals that are linear Class A or AB. Most cheap FM finals operate as Class C amps, no good for AM output.
@@mmpiforall5913 You only need class A/AB on an AM tx if you are modulating an early stage.Most AM tx use a class C PA with a matching equal power AM Audio amp modulator feeding the PA's collector or drain. I've used an AM HF comm rx with a 2M converter and if you slope detect FM (offset by around 5KHz) it RX fine.
haha yeah buddy!!!.. love your work mate!!!
Thanks mate 👍
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.
It worked great on mine, thank you so much. Is there any way to hack the CTCSS frequencies, even by firmware?
Its possible to allow transmit on the 6m 50MHz and 4m 70MHz ham bands, albeit very low power but its a very good start for experimenting!
You mean after the firmware is loaded or by using the secret menu from the PTT button & Power?
@@mmpiforall5913 after the firmware is loaded. I have a cheap Chinese PA power module that delivers around 3 watts for a few mw drive, I've had a few QSO's on 6 6m and 4m. Unfortunately the power out from these handheld radios isn't uniform across the range which will mean having switched attenuators across the different bands.
@@johnlannigan9831 Yes, power output is all over the place, from as little as .2W all the way to 6.7W at 136.5 Mhz!
@@mmpiforall5913 I have my UV-K5 running with the cheap Chinese amp and the output with filtering looks pretty clean. The only problem is changing frequency and remembering to alter the attenuation for different frequencies. This cheap amp needs an input of between 2 and 10mw for a full 3w out. I'm wondering if the output could be limited in firmware in any way, or a method of clamping the input to avoid damage to the amp?
i love how you download a russian developers bin file, and after hitting the limit it says NELYZA) that means "No, you can't)" in russian using translit in this context.
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.
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.
Kurz gefragt ist mit der Software. Der am Flugfunk sauber zu einfangen ohne Verzerrungen
The firmware upload tool has been updated to version 1.1.12. It causes an error on the larger .bin files. Anyone have the previous version 1.1.11 available somewhere? Tnx
Hi!, Just watching this video now I know it's been a while since its out.
at 7:42 how do you make it work so that you can listen to the trunked frequency? You mentioned that we have to manually switch frequencies how do we do that exactly?
I am guessing he tested with output at 500 mW...not much filter heating around the 2M band in his chart. The filters look pretty tight. I wonder if the filters will catch fire?
Not sure if they have changed something in the firmware update software, but the bin files from github are giving me file length errors when I hit update.
I did the firmware update from the link description. The TX version is not working on any of my two UV-K5
So you said there were "a lot of spurs", that means spurious emissions?
Suppose I had the extra rating so I could talk on the hf bands, and I tested the radio to confirm there are no spurious emissions, could I legally transmit on the bands I can talk on? Or is the radio only certified for vhf/uhf, so even if everything else checked out legally, it would still be illegal?
if you have the extra license, and you confirmed your unit has acceptable levels of spurious emissions as per your local government radio comms agency regulation, then it would be legal
doesn't matter what device you use, as long as you're following regulations, it would be okay.
though if you use a device designed for vhf uhf and you modded it to work on hf, I doubt you'll get enough power out of it
@@didotb01 thanks for the good reply! My dream device is a handheld that can rx/tx on every band. I'd be fine with 5 watts of output power because I know how important a good antenna and placement is, and I don't mind hooking it to different antennas for different bands, some of which could have amplifiers inline.
I just hate the idea of buying a nice hf radio that costs hundreds of dollars, but has to stay at home and can ONLY work on hf. I want a unit that can do everything and I can bring it with me
I had a ham test his unit at Hamvention, he told me it passed.
Do you need chirp to download the firmware? I’m a total noob at radios. Should I just stick with the stock firmware?
are supoort unlock too for k6 radio?
Bonza !
perdona macho y gracias por los videos . una cosa , ya lo hice pero no me deja transmitir solo recibir . en cb . podias ayudarme . ?
Is there a way of using the programming software outside of the normal allowed freq's?
Mine won't let me put CB freq's into the software program.
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.....
What is the best radio tools software to use for downloading the UV K5 firmware
what do you mean radio tools software? Like every other Chinese Factory CPS
Its MS Windows
Soll das heisen Dasein am Band jetz die Frequenz nicht immer leicht daneben hängen
What software did you use to programme radio i cant find it please link
Thanks, works perfek!
But how is it possible to manage the new frequencys in CHIRP? CHIRP doesnt save this "illegal" frequencys
just done four of these, and my god....not as you'd think..
18, 20 and 28MHz all 1w or less, but will show between 90 and 110MHz higher on a counter (harmonics and lack of filters)
51 and 70MHz around 2w and show frequency on a counter and down to -108dBm and -112dBm.
145 and 433 around 3.5w with -128dBM and -131dBm which is great,
Airband was 4w..!! at -129dBm..
they do manage 1290Mhz..
but it shows around 100mW and frequency is showing 129.0MHz on a counter, although it is heard on a 23cms radio..
worth the effort ??
for £15 why not, at least you get 4mtr and 6mtr as well now, but use the correct antenna and ideally a band pass filter..
Very cool!
It was fun to play with. Receives 850 MHz well!
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
Hey!! whatsupp!
I don´t know why, I am cannot download the firmware for this radio. (from the official site). I click on the link and it does nothing... PLS HELP!! It does the same on my notebook and on pc...
Will this firmware update allow AM receive in the 300mHz range?
It should go to 27 MHz CB band as long as it will allow AM mode it be good for that. You can use the USB 3.0 cable also to program it.
You can? I've plugged it in several times out of curiosity and it doesn't even register in device manager in windows nor show up under lsusb on Linux. At least for me it didn't, and I tried both USB A to USB C and a C to C cable. No luck.
@@DeLorean58 Hmm mine did but it not allow to open as folder it shows as USB device on mine using Linux.
@@DeLorean58 tbh that would seem logical to upgrade it since it's got USB, then IDK what else it will do, if it's got a modem function of some sorts. But I think the fw ROM can only be flashed using the UART port behind the headset jacks.
the cooler thing would be networking via USB, shown as a standard modem, all that on HF/VHF for long range, but hey we can dream!
Has anyone had this rx on 11m or 10m? It has AM so 11m am? I have this radio amd that would be cool
@@josephwade3241 yes it works with the correct antenna and auto tuner just to be sure
That's in RX only?
I'm a pilot and having a backup radio would be a plus in case of an emergency
Anything on a fix for the airband AGC response issue?
Quansheng's official firmware may have a fix, but they have no release notes. Also try an external/better antenna
Interesting to hear a Aussie state a distance in miles, you use Km over there dont you?
Us Brits and the yanks will appreciate a distance that is easily imagined in our heads :)

Eo baufeng 17 pro tem como desbloquear também? TKS Fort 73 de PU2VOS André. Tks
that's an edacs system, i know those sounds anywhere
hi, in how mode i know this radio is the First or the Second VERSION model ??? this expantion fix FW is only for the band or have the SSB receiving ? 73
K5 has white backlight, K5 (8) and K6 has Orange backlite and a different case
The incl. TypeC to USB cable is solely charging and dont give acces to programming?
is it mandatory to gte one of these baofeng programming cable to upgrade it?
or could I use that incl. earphone cable with K5 that got that dual jack interface, and then cut the headhpne-end and suit it with a USB plug, if it got enough wire-strings and you know the USB pinout?
and use that as a makeshift programming cable.
No programming on the USB-C.
Yes you'll need a programming cable. Cannot use the earphone as you'd need a USB to serial converter chip and some other bits.
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.
So with this mod I could listen to CB radio and pmr446 in the UK? And there is a transmission mod?
Nah, the TX won't stretch that far... hardware limitations then.
@@HamRadioDX so what can the tx mod do?
Ware do you download that program portable radio tools?
The reciever is low on sensitive tried it on 1296 mhz 23 cms, need to be on high ground and high gain antenna possible pre amp
It's about time to buy another radio
Hi Thank for those explanation.
Do you know if there is a firmware update for macos ?
I performed the update but due to a power failure it failed to complete the operation. Now it goes into programming mode but it doesn't work anymore. Any idea how to reprogram?
which frequency generator are you using?
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?
Show. I did and worked. 👋👋👋👋👋👋👋
Great job!
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?
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.
@@HamRadioDX poke inside and play with the coils?
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.
Is it possible to unlock the frequencies of 50,000 mghto talk on the quansheng uv-6k?
Now is the software availability intentional or not ?
