"Just leave it on...we'll control it from the truck"

[KBAustria]

Never leave control of your mike to anyone else. Turn it off when you don't need it, unless you want the whole audience to hear a private remark like "Now, what the ..."
It happens often enough when the mike is controlled by the R, it's not necessary to add further probability for mishaps
If switching the mike off produces unwanted static noise or something like that, then leave the mike in the dressing room.

KB - that is the smart thing to do. In fact, because of this conversation, I may contact the station and suggest they get a mike with an on/off switch. We'll probably be on again once or twice this year - I had no problem our second televised game on that station last year, but I was uncomfortable.
