The PMSDR is a small, low-cost, HF bands full coverage "Software Defined Radio" receiver that use a computer USB port and delivers I-Q audio signals to the PC's sound card. It's similar to the "SOFTROCK XTALL project", but with many more features. This way a great many hams can listening all shortwave bands (from 100 kHz to 55 MHz) that can be achieved by having just a low cost hardware working with the powerful (free) software WinRad, written by Alberto I2PHD and now also with Jeffrey's WinRad, PowerSDR-IQ and SDR-SHELL (for Linux) on the PC.
The firmware can be upgraded easly through the USB Port.


NEW! (3/2/2012): This board is sold already modified like described in "Modification for PMSDR2.12".

This kit is delivered as a preassembled kit (only the SMD parts are preassembled, using automatic pick&place equipment and a preprogrammed microcontroller), so is it quite easy for most people to assembly only the "big" through-hole parts (LED's, strips, connectors, crystal ...) on the board.

The kit includes:

- PCB 80x100mm with Doku. print, all 175 SMD's are already preassembled.
- Si570 XO programmable clock-oscillator Si570BBC000141DG , LVDS, 20ppm
- Amphenol high quality BNC - Female (B6252)
- Jack - Female
- USB - Female
- Stripline
- Buttons, crystal and Led's
- Transformer T4-6
- Schematic diagram
- Assembly draw
- CD-R with: user manual Applications & drivers
