QUICK OVERVIEWThe 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 was designed by Martin Pernter IW3AUT and it's similar to the "SOFTROCK XTALL project", but with many more features. This way a great many hams can listening all shortwave bands 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, G8JCFSDR and SDR-SHELL (for Linux) on the PC. A powerful DLL Interface provide the PMSDR as bidirectional tunable Panadapter, and many possibilities to interface the PMSDR to other software and/or transceivers.

System Interfaces Block Diagram
- continuously tuning the entire HF-spectrum: standard tuning range: 0,1 - 55 MHz
(some boards delivered after Sept. 2010 works also above the guaranteed upper limit of 55MHz, up to 70 Mhz)
- extendend tuning range up to 165Mhz with reduced sensivity through the 3th harmonic mode- measurments test results (TNX to Eraldo, I4SBX)
An external preselector is recommended for frequencies below 2MHz and for the 3th harmonic Mode.
- IF amplifier output clipping level: 2,45Vp @ -13dBm RF input level
- IF (I and Q output signal) bandwidth: 155 kHz @ -6dB
- Power supply : 5V / 155mA (+15mA with LCD module)
- USB2.0 interface, only USB powered (no external supply are required)
- high speed divider CYPRESS CY22393/4 (for the tuning range: 0,1 - 2,5 Mhz)
- new low jitter clock generator SILICON LABS Si570 LVDS
- interface for optional LCD
- interface for optional boards (transmitter, preselector ecc.)
- 3 Bandpass filter on board + 1 Lowpass filter on board + filter bypass (broadband input)
- IF-Chain with rail-to-rail OP-AMPS for 5V
- I/Q outputs for PC Sound card
- I/Q optional differential outputs for professional PC Sound cards
- PIC18F4550 Controller with USB-Bootloader
- DLL support trough USB interface for Winrad by I2PHD & PowerSDR-IQ
- PCB: dual layer, 80 x 100mm
