From a practical matter, how does the deaf pilot report 10 miles out
without steeping on other transmissions? Is there a device for this?

Some (most/all?) radios have a light that comes on when it is receiving a
signal, often green and another light when transmitting, usually red. My JRC
and Icom handhelds and Microair radios have these Tx/Rx indicator lights.
