That is the case in the US and possibly Canada too but not in the UK. It's a good reason for not importing a VHF radio into the UK because ch16 will default to low power. Some US units will allow low power to be overridden to give full power but it will normally revert to low power as soon as the PTT switch is released. Rather inconvenient in use.
