Seems to me that there should be some sort of alarm, hooked to the radio
and which goes off if some small number of radio receptions occur without
any transmission by a controller in the tower cab. You'd need to set the
number higher than 1, but fewer than a dozen would probably be fine, and
would probably have woken this guy up in this case.


Just increasing the volume prior to napping works well. So I'm told.
