Last year in April we posted about the Teensy SDR, which is a SDR project that involves running a SoftRock SDR on a Teensy 3.1 Microcontroller. The Teensy is a tiny microcontroller board that uses a 32-bit ARM processor and the SoftRock SDR is a HF only software defined radio kit that is capable of RX and TX. Back then the Teensy SDR has no enclosure and the user interface hadn’t been finished.
In his latest YouTube videos, creator of the Teensy SDR rheslip20 (aka VE3MKC) shows his latest improvements to the project and in the second video shows off the user interface. In the future he hopes to implement TX capability too.
