I have a lafayette cd4 demodulator and I need to know if it's functioning properly. The radar light never comes on while playing cd4 records, or the jvc setup disc. My question is, can I go into audacity and generate a 35khz tone and just run it into the demodulator. If the demod was working ok shouldn't this light the radar? I'm trying to figure out how I can tell if the demodulator is working properly or not because I need to know if it's the demodulator or something else in my setup.
