Ben,

When is just clicking PTT an acknowledgement?


Never, ever. Period.

There's a lot of supposedly cool stuff being said and done on the radio
which in the end is just hogwash. This is one example. Others are "with
you", "tally-ho", "no joy" or the ample use of "Roger" where "Wilco"
would be appropriate. If it's not in the AIM or the PC/G, don't use it.
