I had unexpected challenges in
I had unexpected challenges in building and troubleshooting the (tr)uSDX Ham Radio transceiver kit. In general, this QRP radio is becoming very popular among the QRP radio enthusiasts. It is fully SDR design yet simple and ingenious schematics. It’s roots and prototype go back to the QCX radio from the QRPLabs. At the moment, it’s a unique multi-band design licensed under open-source rules by two hams - Manuel, DL2MAN and Guido, PE1NNZ. The license gives a right to anybody to produce and sell commercially this radio with the only condition it must be approved by the authors and produced with no changes to the original schematics and PCB’s. At the moment (October 2022) there is one kit maker from China approved good to make and sell the (tr)uSDX kits. Another company from Romania was producing the kits for a short time but is not now , except of selling out some stock items. All information on where to buy and explanations regarding the relations with the Romanian company is on the Manuel’s website https://dl2man.de , as well as all the technical information about the assembly and tuning.
My Chinese kit is functioning now but it took some time to figure out what was wrong and how to fix it. Some issues I left unfixed with a hope of good advice from you, friends. Please leave your comments in the comments section. I also have the Romanian kit which turns to have the dead MCU on it. I’m planning to replace the Atmega328P in this board, but not in today’s, in coming videos. So, please consider subscribing, if interested!
