Directed messages too - so I don't need to hear somebody modify a flight plan etc.
Radio has progressed, but in practice digital transmission isn't necessarily all you suggest, and BTW what protocol should we use (oh, just think of the headaches trying to work that standard out!).
There is still a place for simple analogue radio that has reasonable range, works everywhere around the world, and doesn't have multiple buttons for you to f*** up and miss making the area broadcast you should make...
However I agree some AM transmitters may be less than perfect. Perhaps when they're inspected it should be a requirement to put them on a SpecAn to check their harmonic levels are ok? Also properly checking antenna connections & bonding etc so something isn't rectifying, mixing, and re-transmitting (or receiving) on another frequency would surely be some steps to go through in order to resolve whatever issue is occurring here.
