The T1154 transmitter and the R1155 receiver were the first radios I used to transmit and receive signals (in my teens in the 1960s). These transmitters and receivers were used in Royal Air Force heavy bombers and other aircraft during World War 2. These transmitters and receivers used Morse code and the morse code signal used to ‘chirp’ (sounded a bit like a demented bird on drugs!). Some ‘chirping’ Morse code here.
