How wide is the audio bandwidth?Do you have to add that NRSCA post reception Eq so that it doesn't sound shrill? All AM BCB statiosn use the NRSCA pre-boost. The inverse shape is needed to compensate.
Or are Mr Rippell's mods sufficient.
We have a few very good wide-band audio transmissions on the AM BCB, and I've put a fair effort into getting good sound from my old valve RF stages 'tunah'. Search here.
