Maybe I misunderstood - I thought he was suggesting using pads while tuning,
not during long-term operation.
Still, there are situations where pads in front of the receiver won't make a
change in usable sensitivity, but will improve intermod/overload
performance, such as at a site with an elevated noise floor. I remember
working on a 2m repeater on a cell tower that was under high-tension power
lines; a 10 dB pad ahead of the receiver wouldn't have changed the usable
sensitivity.
