I should have clarified that this referred to in-flight operation.

Er...maybe because the "coffee grinder" controls hanging out in the open
got tweaked intentionally or inadvertently while in flight.  This was
a very common complaint, and once it occurred there was no easy way to
get the receiver back.  The pushbutton selectors with no tuning controls
on the early VHF command sets were praised by pilots in comparision.
The problem was enough to lead to the stabilized preset lock-tuned
command set communication receivers (R-25, 26, 27/ARC-5) in many USN
aircraft.

A fighter pilot isn't going to pull out a LM or BC-221 and adjust his
receivers with it in flight. :-)  This isn't easily done even on large
aircraft with a radio operator, since the receiver controls aren't at
the radio operator position.
