Aircraft VHF coms should have changed to single sideband suppressed carrier (SSB) mode a long time ago. Doubled transmission would be easy to read without the carrier beat tone.
Never going to happen though as too much amplitude modulation (AM) equipment to be replaced now. If it had happened 50 years ago we'd all be used to it now. It could also have been introduced when many transceivers had to be replaced for reduced channel spacing.
