usDX 3 Band Portable HF Transceiver - Any Good?

[@normnpat]

Ordered from Ali Express and want compliment them on their quick delivery and the radio works great. First day hooked up to 12volt power supply and made several contacts on 40 meters, all at a distance of about 250 miles from my qth. Qrp is my favorite part of ham radio and this little radio makes an excellent addition to my collection of tranceivers.

[@kchaney56]

Sweet, I am not usually not interested in a low power radio but this one is super small and very cool, match this with a GREAT ANTENNA and you could hit gold.

[@johnnorth9355]

I have the larger 'black brick' version and have hours of fun playing around with it . Cleaning the circuit board is a must if you don't want (even more) strange things happening and junk the supplied microphone - they are rubbish. The internal mic works well and get the settings right and you can work condittions to very acceptable distances at QRP power. For a cheap portable bit of fun they are brilliant because if you drop them (I have) it's not an instant gasp of horror. I use mine on a small magnetic loop and on a EFHW which it seems to work best on. The black brick has an internal battery (great and lasts for hours) but the extra bands are rubbish as the tx power is so low. 73 M7BLC. NB - SWR needs to be well below 1.5 for good results.

[@TruthVSLies]

I have the black brick as well. Very good at JS8call with it. Though I don't think I'm getting the 5 watts, as the built-in swr meter says 1.5w. Either way it's working well enough. And yes, the battery seems to last forever.

[@johnsinclair3067]

Just ordered one a couple days ago. Love the form factor as it's more like the qcx mini than any other of the SDX variants. Time to start planning an internal battery and usb-c mod. Thanks for the run down.

[@Bueromensch1]

i have one and it works so well (in CW) on my FD3 Antenne.. i use a Atu-100 tuner. I have QSO,s almost every day with europe (20m often with 599 Rprt). Great nice qrp rig! i love it. 72 & 73 de HB9LBX

[@heinerrambold8889]

Bought a truSDX kit some time ago. It features a small oled display and I could choose if I wanted the lower bands oder the higher bands. Wired it so that now it covers 80,60,40,30 and 20m. It is quite ok for such a small radio. It has a proper tx signal ; not standard with chinese qrp rigs. Thanks for the video!!!

[@DarthTater5738]

For that price you may as well get the 5 band trusdx

[@LeeMcc_KI5YPR]

Sure. But this case looks so much better than the 3d printed trusdx. Performance? Hard to tell without testing.

[@dogastus]

The Chinese writing on the end plate translates as "I have you in my dream, very nice!"

[@DerekDominos]

With this dream Chinese became reach and you became poor without factory and than without work

[@Panoramix0874]

For this amount of money, you can get a QMX with the same form factor and that is a superior radio in my view. You should test it IMHO...

[@johnmine5609]

this Radio and a 40 meter EFHW a rechargeable 12 volt battery and a BOOFWang UV-5r and a rollup up Jpole and you have a nice small and cheap go box com setup for the ShoeString Budget folks

[@HamTechRadioScannerDrones]

I like mine :)

[@dimitristl]

I Bought it a couple of weeks ago, I believe it needs new firmware because it is for three bands and the software supports all HF bands, and also the software has SWR/PWR indication but there is no ferrite core inside detecting SWR/PWR. The last problem have turned me to open the cabinet to check why the SWR /PWR indication was Inop, it was showing permanent SWR 9,9 when it was ON, and I found that there is no SWR/PWR sensor Hi Hi I have also installed pins to ISP programing provision on PCB for future firmware update, and the last, in order to save money they used two M3 screws to support the display board on mother board instead of four as it happens to your radio too Hi Hi

[@eacuatrogndecoalfagnd5295]

the ssb audio quality is much good than usdx v2 plus thanks for this review goog job EA4GND thanks

[@johancolpaert7663]

Would like to have one too for mobile use attaching the audio out to the car audio system

[@multilecful]

Looks pretty rough inside. Like its been through the dishwasher 😮

[@LeeMcc_KI5YPR]

Some PCB shops use a dishwasher to clean water-soluble flux.

[@audiobrian1]

@@LeeMcc_KI5YPRyes indeed, and that results in cleaner looking boards then the traditional solvent - cleaned boards, in my experience.

[@nnasab]

I like it as a back up, also the price is good.

[@DerekDominos]

I like it as rubbish

[@66vds]

Какова частота установленного туда кварцевого резонатора? 16 или 20 МГц?

[@MRSZ5440]

I want to ask a question do you need a roof top radio antenna to get good TX/REC?

[@JohnR_ytbe]

It's cute... I just can't see me actually using it. Nice to see it though.

[@ihavecojones]

Why?

[@kb9mtd-aaronwebb]

Hey Matt. Have you tried to populate the USBC space with a connector? They can be found free(ish) on vape pens! I have some here and would love to know if population of this connection makes sense. 73 for now Thanks for the video!

[@TechMindsOfficial]

Hi ya! I didn't look to closely, and my initial assumption was it could be used to charge an internal battery, which of course would need some kind of charging chip. So I think if the USB C socket is missing, so would any further components. If I get a chance I will open it up again and take a look, but I didn't really want to remove the LCD where the components would most likely be, if they were there. Cheers and thanks for watching :-)

[@MidlifeRenaissanceMan]

Re the CW settings. Does it support a straight key ??

[@DerekDominos]

It support a silent key

[@MidlifeRenaissanceMan]

@@DerekDominos ghost key ???

[@TruthVSLies]

Might be a good little qrp JS8call radio.

[@TheArtofEngineering]

Looks like the QMX but that is 5 bands.....and a better rig :)....Even without SSB.....which is slated for firmware updates. 73 de VK2AOE

[@johnc3403]

A QCX-mini or QMX with SSB out of the box (I know there's a little board and mod) would kill off the competition, imo. Particularly with POTA SSB activations becoming so popular.

[@mikewillis1592]

I never got the point of these radios as you still need an antenna. By the time you have packed that and the battery and an antenna tuner, you may as well take something with all that built in. KX3 for example or X6100. OK so it is cheap.

[@lampshadesneeded]

i would get one for travel. i fly crap european flights with tiny baggage allowance. this and efhw can fit in a pocket. also if it gets lost or destroyed i wont be so sad

[@LouiseBrooksBob]

Don't need a tuner for a tuned antenna. A 40m end fed half wave would cover all the bands for this radio: 40 metres, 20 metres and 15 metres.

[@TobotronPrime]

Generally I agree I have the X6100 and a G90 both just work - but these are fun to experiment with and you don’t have to be quite so delicate with packing/handling them.

[@mikewillis1592]

@@LouiseBrooksBob An end fed would need some form of impedance converter to 50 ohms though.

[@DerekDominos]

The difference between this radio and Kx3 is like a peace of shit and something good to eat

[@welshbikepackingadventures]

I want one!

[@DerekDominos]

But you need to pay for this Chinese rubbish

[@zerobow9413]

Maybe $50 earth dollas

[@Hank_W6IR]

They were too cheap too even comment out a few lines of code for band selection from the usDX 8 band radio.

[@lampshadesneeded]

maybe its so you can change the filters. if i had one i would lose 40m and change filters for 10m

Brother... It's a multiband, smaller than palm size HF transciever (it's slightly bigger than the pixie) capable of SSB, costing less than a "proffessional" VHF HT. What the hell do you expect?
