The whole project is based on an idea of a swedish fellow, which in his page describes
the use of a TV tuner to construct a radio tuner which receives the frequencies
between 45 and 860 MHz in a step of 0.011 Hz controlled by a PC using a serial port.
I have used his idea to construct a control unit based on a PIC microcontroller to send the
control codes to the tuner, and a 2x16 LCD display, showing the frequency and mode received.
Below you will find the improved schematic of the receiver and the control unit.

The superscanner main board Control unit version 5
The enclosure pre-painted and coloured
System assembled and wired for testing
Right now I am working on the code for the PIC microcontroller which will be published
when I will be satisfied by the results.
