Thanks for your clever design and work.

I learned decades ago that if you have such a device and want to profit from it you need to do your own manufacturing and selling. When a copy appears you produce V2 and so on. Don’t waste time on patents. In VK we had trouble with US firms making without licence, then some EU countries. China has only started this lately.

Commerce 101 teaches that the selling price is not related to the manufacturing cost other than it must exceed it by as large a margin as you can sustain. It’s a market price.

Sure your kit of parts might cost $50 but it takes a few man hours of specialist labour to assemble. Then there are all the costs associated with selling, advertising and freighting. Add another $100. Now a retail price of $200 looks modest. The cost of parts for any electronic device is always the least expensive component.

Thanks to you and your colleagues and I look forward to the next iteration.

Manuel DL2MAN has done some measuring. Not so great.

There is few group buys for the (tr)uSDX 5 Multimode QRP TRx, but if you are happy to wait for a kit next pre-order starts 5th Feb 2022 and mentions assembled units may be available March-April 2022.
This is a pre-order this product, £75/€90.

I ordered one of these uSDXs (vB as described by EA2BD) via AliX & received it in time for Christmas. In between numerous helpings of mince pies, I tried it a number of times in a few different locations with different antennas, power supply etc and the receive signal / audio was always very poor. Even with the bandwidth fully open at 3k I still couldn’t make out any SSB speech clearly as the sound was overtaken with a scratch rasping sound. It then completely shut down after maybe 30mins of total use so I arranged a return & they refunded my total purchase inc. shipping. Needless to say, I won’t bother with any more of the ‘cheap’ transceivers and will stick with my Yaesu FT817 for futuree SOTA activations.

73 all, Lea

I took mine out portable the other day - remember it doesn’t work perfectly out of the box, you need to dial it in…

Wade is right. A little adjustment goes a long way. To get decent receive audio especially. Must turn off AGC and NR, choose ATT and BW carefully. If done it as good a CW receiver as most others. Mine makes good power 80-15 but dead on 12 and 10. Overall 4+.

Hello everyone, I work SOTA with 2 QCX-mini on 20 and 40m. I may be interested in building a (tr)uSDX. Who has a comparison on RX performance between these two rigs?

Hi Nico,

As the main change between QCX (mini) and (tr)uSDX is in the transmit stage (parallel resonance class E system) I would expect a very compareable RX performance.
Maybe even a bit better as a lot of improvements went into the software since the QCX was released.

Thank you Joe, OK for example side, and if I understood the efficiency of the QCX TX stage is better .i.e. less consumption for same output power and coller output stage. Best 73 nico
