If ask someone to standby, I mean just that;
"Wait for me to finish doing whatever I have prioritised over you and I will get back to you."
The response I expect?
at most, one or two of them quick r/t clicks will be fine. I dont need your callsign, I know who I've told to standby and even if there was confusion, your callsign will be at the beggining of the relevant transmission anyway (as it would be on my "pass your message" command).
Thats my opinion anyway.
Traaaaaaaaaa.
