IF and detector board  


  This kit is an IF amplifier and detector board for an FM tuner.

The IF bandwidth is switchable between wide mode for low distortion and narrow mode for better selectivity. An 8-pole 230kHz filter is used for wide, and 180kHz and 150kHz filters are added for narrow mode. Even narrower filters like 110kHz can be used also.

The detector can be double-tuned for even lower distortion, but for that alignment a signal generator and a distortion analyser is needed. Basic alignment can be done using a multimeter.

The board also includes an ADC for implementing a field strength meter, and a circuit for generating stop signals for automatic tuning.

The board needs 15V DC, which is normally supplied by the MPX board.
