I find this a very interesting topic. As it has been often said: Ask 2 hams a question, and you will get at least three opinions. So, I was thinking, is it legal, when using a repeater that requires a PL tone to access, ID with your PL turned off? I guess what I am really asking is do you have to identify yourself through the repeater, or just identify? Though not exactly the same thing, I know a lot of commercial repeaters turn off their transmit PL when IDing. Commercial users don't particularly like hearing a MCW ID all day. I know it would be inconvenient to actually try to turn off PL to identify, this is more of a hypothetical.
