Be careful what version you buy, or you could end up with something like this!
I believe someone, somewhere is mixing up the various uSDX/USDR model radios and combining them all as one model. If you Google uSDX, there are some excellent reviews of that radio - which looks nothing like this model. That radio has a tuning knob in the front and a SO-239 rather than a BNC; which this radio has
And always remember, for roughly $175 USD, you are NOT going to get a Yaesu 991A when you buy one of these.
Good post Bill!
Thanks for posting, you seem saved me from buying this trash.
I'm sorry that you were ripped off. The number of un-Godly people on the planet seems to grow exponentially.
You can easily find these clones in Taobao / Alibaba website. Nowaday many CN hams make / clone products and sell them internationaly, before these are only sold locally. Their concept of IP are very weak, and wonder minor product adjustment can save them from infringement, and particularly on those open source projects like VNA. So, buyer shall be intelligent enough to pick the right piece of product to meet their need, and promote IP right.
Glad this video was posted, this "clone" has really taken off the last few months on all the typical sites t hat have a lot of Chinese stuff. Hopefully the TechMinds one is a bad one off situation. I've yet to hear one on the air, the more simple looking version that doesn't have a built in battery and in a smaller housing seems to run around 129 US dollars. however, if any or all of them have a TX like the one in the video that may as well be a receiver only.
Well, gee whiz. I the review above doesn't seem to cover any of this cheap little SDR's menu configuration settings or indicate any attempt to properly adjust same for optimum results. I purchased one of these little guys on a lark, in fact it is the same exact one as shown in the review above (Software Version R1.02W), except mine has a properly sized smaller tuning knob. I have been a long-time home brew QRP fan for many years now going back to the early 80's but never dabbled with any SDR radios. It took some digging, but I found some rudimentary operating instructions for getting into the menu settings and making adjustments to set them up for the results I was satisfied with. After making sure I was not overdriving the audio and TX Drive parameters (TX set to 4 worked best for me with a PA bias to about 180). From my home QTH in central Ohio, I fired this little puppy up and right out of the chute on 20 meters I responded to a SSB POTA CQ from Scott about 20 miles south of Omaha running (POTA #K8283). I received a 5 and 5 signal report back from him in a nice QSO. I was running on the internal battery and pumping a whopping 4 watts to my 6BTV vertical out back. I was really thrilled I could make this little cheap guy sound good, hear at least decently, and actually work. While the receive side is unquestionably noisy, you can reduce the noise with the menu NR adjustments. On the lower bands like 80 and 40 meters, you can kick the ATT function on and set it up to about 13db to quiet things down to at least a reasonable level. But hey, what do you expect for something this inexpensive. Anyhow, this was my experience with the little rig, I happen to like it and I am going to keep it and may use it this next field day. Take this review for what it's worth, or not. Your call.
Best of 73's to all.
Some kits are lightyears ahead in the opposite to this what was shown in the video.
It is amazing how many hams are buying these chinese copy cats.
The uSDX project tried to work with Chinese companies to mass produce the radio and It eventually fired back and the Chinese ended up copying and selling a poor version of it.
Long story short, the only way to get the real original uSDX now called (tr)uSDX is by buying a kit which is right now available from two sites in Europe.
If you are interested in the long story, head to dl2man's website and you will learn how the chinese are selling poor copies of the radio.
If you think its cool to buy rip off projects from hams, keep buying uSDXs out of ebay and Aliexpress.
I'm still waiting for my kit to arrive.
