What do you do when requested to "recycle" your transponder?


I was told that was the ATC's way of saying, "Hey...you forgot to switch
your transponder to ALT before you took off!" without embarrassing you.

Wow, lots of misunderstanding out there. Recycle transponder means to
turn it off and then back on again. "Check your transponder on" means
you have taken off and we are not receiving it when we expect to.
"Check mode C on" means we are getting the transponder but no altitude
information. If we are getting the transponder return and an altitude
but you didn't tag up properly it is because the code is wrong. 75% of
the time it is because you entered it wrong, the other 25% of the time
is because you are hangaing on to that piece of **** and even though you
entered the code right it decided to transmit a different code. Banging
on it usually clears it up.
