Should the receiver's AGC be disabled when testing a transmitter for

or better?
I doubt that it matters. What *does* matter is that you must listen
*away* from the transmitter's frequency.
To check for clicks, use your narrowest filter and tune off the signal
frequency, both up and down. If the transmitter is producing clicks,
you will hear them when the actual signal is outside the passband. Some
rigs produce clicks 3 or more KHz from the frequency.
Some people think that you check for clicks by listening to the signal
and hearing how 'hard' it sounds. This is not the case; you can easily
soften the signal to your ear by using a narrow filter. The real test
is "is the transmitter generating click energy away from the signal?"
