I know someone could chime-in with a better understanding of this theory.
The AM on my Toyota Prius, doesn't sound that good.
I bought an older Japanese built HH Scott receiver, that was designed for better AM reception, as it has a three gang AM tuning condenser and tuned RF stage.  |
For maximum range at a given power consumption most modern transmitter rigs use DSP to compress the audio such that they can maintain 100% modulation (or as near to it as possible) almost constantly. IIRC PWM and other less than linear tricks are employed to reduce power consumption as well. It sucks for music, but in terms of keeping operating costs down (and thus pleasing corporate bean counters) it is a very effective system.
