interval between (a) the instant of
keying off the local transmitter to stop transmitting and (b) the instant the local receiver output has increased to 90% of its steady-state value in response to an
RF signal
Radio waves (formerly called Hertzian waves) are a type of electromagnetic radiation with the lowest frequencies and the longest wavelengths in the electromagnetic spectrum, typically with frequencies below 300 gigahertz (GHz) and wavelengths g ...

The RF signal from the distant transmitter must exist at the local receiver input prior to, or at the time of, keying off the local transmitter.
Receive-after-transmit time delay applies only to
half-duplex operation.

Transmit-after-receive time delay
In telecommunications, transmit-after-receive time delay is the time interval from removal of RF energy at the local receiver input until the local transmitter is automatically keyed on and the transmitted RF signal amplitude has increased to 90% ...

Attack-time delay
In telecommunications, attack-time delay is the time needed for a receiver or transmitter to respond to an incoming signal.
For a receiver, the attack-time delay is defined as the time interval from the instant a step radio-frequency signal, a ...
