THE MOST ILLEGAL CB RADIO EVER!!?? | QUANSHENG UVK58

The Quansheng UVK58 is a radio hackers dream, because it's based on the Beken 4819 rf chip which covers between 18 MHz - 1200 MHz. We have already see how well the receiver performs thanks to other youtubers, now lets see what happens if you try transmitting with it!

Firmware tested:

This video shows tests conducted in a controlled environment, I am a licensed amateur radio operator. I am not responsible for the irresponsible use of this firmware.

This randomly appears in my feed and I have no idea what any of it means or why this guy is so excited but I’m just happy to be here for the party 🎉🎉🎉🎉🎉

Looks perfectly fine for CB band!
Splatters over 10Mhz ✅
Has roger beep capability ✅
Mic turns up past 100% ✅

@2:25 Ham operator here. And no not complaint at all. You are wonderfull doing showing what are the risks on doing this . Teaching people about this ham or non ham is wonderfull..!! Keep up the great work mate. Radio is wonderfull... Loving your videos !

As a ham operator of over 40yrs I'm all for these cheap Chinese radios, their value for money is off the scale!😂👍

It's worth noting, for anyone who is after one, that the UV-K5, UV-K5(8) and UV-K6 are all the same guts, just in a variety of similar cases, and different backlight colours.
The UV-K5 plus, in addition, is a hateful thing with a jarring blue backlight and no USB-C charging.
UV-K6 is my preferred favourite.

I've had a handful of those 'illega' CB radios. Small list - Cobra 2000 with extra channels, Golden Eagle with extra channels, Trinidad with extra channels, Yaesu FT-101e (i know not illegal but I used it on CB), 5k linear amp with a set of Moonraker 4 beams. Miss talking skip and CB's in general. Great video, thank you!

[thelydiaspringexperiment]

a few of us are working on hardware mods to match the firmware. the filters will be switched by spare gpio to give a better low pass or resonance at 28mhz as that is the only fm compatible hf band for non type approved amateur gear. if thereis space, filters could also allow 6m band at reasonable power, but i am working on the 28mhz 5w mod.

I am 55, and I have always wanted to learn all about how to use these radios since I was a child. I just stumbled into this channel and sub'd, hoping to learn as much as I can from this community!

[PendejoRyan]

I have one of those. Its surprisingly well built. That USB charging is a game changer as well. I installed the S-meter mod on mine and that was about it. I think you hit the nail on the head about someone developing this radio further and i am excited to see what comes of it.

[leonvanderlinde]

You get military handhelds that transmit from 26 MHz to 520 MHz. SDR can give you the ability to do from 1 MHz to 1200 MHz. You just need a linear amplifier to follow.

This'll stir up the angry old radio men brigade!! 😂😂😂😉

[HamRadioDX]

Great summary and test Andy. The Quansheng is truly a cool little unit that I don't think even Quansheng expected to be so popular!

[superpieton]

The UV-K5 tests on the CB band show that its output power figures are in µWatts (yes, *MICRO* watts -- 228 µW to be precise).

[MhWow]

I have absolutely no idea what any of this language was talking about, but it was super interesting.

[MegaSlimmm]

I haven't operated radio for years, was A and B class license at 14 and 15 years respectively, 43 now. But remember being involved with some cutting edge stuff back then, copper tube wave guide for Microwave frequency transmission and some first satellite packet radio. It's come along way and glad that the door was opened to the interested. Love the look of this, always had soft spot for hand held with power ✌️

[Biokemist-ok]

Beautiful!!! Now I need one to keep in my SHTF box...

[mostlypostie]

*UPDATE! TRY THE IJV FIRMWARE. It will TX a very clean DSB and CW signal on the 2/70 bands. It also has a very nice user interface. 73.

Original post:
In the frequency scanner/spectrum mode, after pressing PTT to lock the frequency in, If you select SSB, And then toggle to the DEV setting and lower this to around 200 or 300, It will actually TX a reasonably good sounding double sideband signal. You can not only listen to SSB but you can talk there too! Amazing. (I did this test on 2m where I am licenced, and where the radio is reasonably clean (on VHF).

[gtretroworld]

Brilliant video Andy and a great little inexpensive radio to experiment with. I am unsure why some are fussing as this is what amateur radio is all about, obviously most know this is always going to splatter where it was designed to TX but for RX there’s no harm in my book.

[Siskiyous]

Radios can be legally modified in America by hams. The only issues would be use out of band, or spurious emissions. The actual changes are perfectly legal.

Andy is the number 1 CB guy of all the radio amateurs. That's why I decide to pass my radio amateur licence. Way to go Andy if you want to lure the top tier cb crowd into radio amateurism.
