Midnight Design Solutions SDR Cube and NUE PSK Modem
I built the SDR Cube and NUE PSK Modem perhaps close to 15 Years ago aafter seeing the articale in March 2008 QST article and learning about Mifnight Design Solutions.
Taken from the documentation: The SDR Cube is a single-band QRP transceiver consisting of an embedded DSP controller coupled with the Softrock RxTx v6.3. Sized at 4” x 4” x 4”, the appropriately-named Cube also contains a full complement of built-in user interface: graphic LCD for spectrum display, typical controls for frequency, mode and signal management, and I/O connectors for connection to the outside world.
Taken from the QST Articale : At the heart of the NUE-PSK digital modem sits a new and inexpensive 16-bit microcontroller from Microchip called the dsPIC33F. This device combines a standard control processor together with a computational powerhouse digital signal processor. While the conventional control processor instructions handle the display and keyboard I/O, the DSP instructions are what actually perform the complex PSK31 demodulation, thus allowing the NUE-PSK modem to be the first economic solution for digital modem operation without the aid of a PC sound card.
