SoftRock page (page always under construction)
In this page are enclosed informations about SoftRock V. 6.0 that I assembled and now is under test in my shack
The Soft Rock is a low cost SDR receiver by Tony Parks (KB9YIG) that implements a simple Quadrature Sampling Detector
(QSD, see A Software Defined Radio for the Masses from QEX Jul/Aug 2002") when connected to a computer sound card and software such as PowerSDR.
These are pictures of version 6.0 I mounted in the 2006 June: (click to enlarge the images)
Initial mounting, the rear PCB has the SMT
parts (a little attention in soldering)
Input filter is a two toroid core band-pass , the third toroid is the mixer transformer
Final result: the three plugs are for : RF input, output to sound card, and power supply.
