Civilian Wartime Radio - Further Notes

[ppppenguin]

It's not the easiest waveform to lock a scope to. When the audio is semi-random, as you would get from a normal radio station, it's almost impossible. If you're using a signal generator it's a lot easier. If the SG has an audio output then you can lock the scope to that. Otherwise many scopes have an HF reject setting for trigger which will pass the audio modulation and reject the RF. Hence it will trigger on the audio.
