I updated one of my (tr)uSDX transceivers to the mainboard revision 1.2 to see if it fixed the “howling” issue.
Category: (tr)uSDX
PE1NNZ has updated the firmware (beta version) on the (tr)uSDX to add audio over USB. This allows for digital modes such as FT8 over USB without separate audio cables.
After assembling the low bands version of the (tr)uSDX, I decided to try the high bands version of the kit, which includes 10, 12, 15, 17, and 20 meters. I mainly wanted the 10 meter band as we’re on the upswing of the current solar cycle.
Building an adapter to connect a speaker mic to the (tr)uSDX is fairly simple and can improve the experience when operating in phone modes.
The (tr)uSDX can be used for FT8 and other digital modes by using it’s CAT capability and audio in/out jacks.
The (tr)uSDX is a pocket sized QRP transceiver, capable of CW, LSB, USB (and AM/FM). It covers 80, 60, 40, 30, and 20 meters. What I find amazing about this transceiver is that it has a VFO, OLED screen, built in speaker and key, all inside of a pocket sized case. Further, it can decode CW and measure approximate SWR and power output.
