The SDR (software defined radio) receiver kit "PMSDR" by IW3AUT is a very easy build SDR-RX, as the vast majority of components are assembled in the form of SMD components already on the board.

Besides the installation of the board in an optional enclosure which is mechanically prepared for the reception of the board and the connecting terminals by means of appropriate housing openings already have been only a few "conventional" components to fit on the board. A construction period of the receiver hardware including software installation on the PC / notebook for the operation of the receiver software is required - provided that adequate computer knowledge - is possible within one hour.

The "PMSDR" receiver use the USB port of PC/Notebook for its power, so it needs no separate power supply.

This provides the interested "surfers" a low-cost All-Wave receiver kit (long wave to 6mBand) and that has to do not shy away from the reception power produces the comparison with more expensive, conventional receivers. Requirement is a PC / notebook with the necessary for their operation software that can be downloaded from the Internet ("WinRad and PMSDR-specific drivers).

Thus, this kit from the price-performance ratio is viewed from particular for newcomers and SWL, and students a very interesting option. But even for "seasoned" OMs / (X) YLs the device offers a wide range of applications, in addition to the well-functioning pure receiver property, as well as to observe the propagation conditions "at a glance" or the assessment of transmitting signals

For the operation of PMSDR a standard PC or notebook with MS Windows XP, VISTA, 7 and a full-duplex soundcard with stereo input is required. As software offers first "WinRad" (free use), since relatively easy to configure.
