Usdx $170 SB/CW HF Radio
« on: October 02, 2021, 03:49:22 PM »

Has anyone bought and used the Usdx QRP radio? I see it advertised for $170 approximately with accessories but the only reviews I have found is a few fluff pieces that were added buy the MFG./Seller.

They quote 5 watts out on internal batteries and 10 watts with the external 12V DC input, SSB and CW.

If you bought one what was your experience with the seller and your impression of the product.

Radio can be seen at: https://www.ebay.com/itm/255126670263?chn=ps&norover=1&mkevt=1&mkrid=711-213727-13078-0&mkcid=2&itemid=255126670263&targetid=4581183927179148&device=c&mktype=&googleloc=&poi=&campaignid=418233787&mkgroupid=1241348861725295&rlsatarget=pla-4581183927179148&abcId=9300542&merchantid=51291&msclkid=d715ade4825811006898ccbc6079b514

To quote Clint Eastwood, "Do you feel lucky? Well...do ya?" After all, it IS flea-bay.

Looks like a clone of another radio I've seen, maybe one of the Xiegu radios?
They say if you get a defective one, you have 30 days to return it, and you pay the shipping. To China, of course.
Based on some of the typos in the ad, it seems like they really don't know what they're selling.
Hilber transform? Seriously? It's Hilbert transform.

I don't know, if you've got $170 you won't miss, and you feel a bit lucky, this might be worth a try.
My gut feel says this is something to stay away from.

Mike - you can build one for a lot less.  I ordered some uSDX boards and a sack of parts and had less than $100 in my uSDX V1.01  This is the one I built and I may have talked to you on it, can't remember...

I bought one that was similar, and sent it back after a week.

in a nutshell it had poor sensitivity, and had unwanted emissions on whatever frequency it was set to receive on.

nice idea, nice form factor, not really for prime time IMHO.

There is a section on the uSdx on https://groups.io/g/ucx the discusses the original kit, as well as the Chinese knockoffs.

Please take a little time to read the notes by DL2MAN (he develloped uSDX) and how Chinese dealers try to make money:

Thank you for reading and viewing before ordering!

This story just keeps repeating itself & sounds just like the "Recent RS-918", a Chinese ripoff of M0NKA's nice little mcHF transceiver.  Nothing anyone can do legally, but we can vote with our credit cards - just stop buying Chinese ripoffs, support the designers by buying their products.

I recently purchased a Chinese knock-off of the usDX rig which is called the usDR+ on eBay for $188.00. It has worked great on SSB putting out about 7watts. This past weekend I worked stations on 20m, 15 & 10m. I live in So. TX and contacts were East Coast, West Coast & Canada. If you purchase one of these the factory settings need to be adjusted after a coupe of hours I got it working good. Some HAMS that got it on eBAY say it is a piece of junk, well I found that it is a good QRP radio once setup correctly.  73

always good to see more rigs on the market... the usdx has now appeared on the s. american river, so you will always get your money back on a bad purchase... last time i checked they were ~$180

You can now buy a "non-clone-knockoff" uSDX kit here:
 https://rowaves.com/product/trusdx-5-band-multimode-qrp-transceiver-kit-assembled/
as referenced by the designer DL2MAN here:
 https://forum.dl2man.de/viewtopic.php?t=62

There appears to be a waiting list.  But it doesn't seem too long.
