Get a pair of FRS radios with a call button. Push that and it makes a noise on all other FRS radios in range on the same channel. For your use you'd want an older pair with shorter range.

I don't even know if such a critter is available, but I don't want to be slaved to some monthly service like they tout endlessly on the telly. Something about the size of the fob for your car keys with its grouping of buttons. Those things are tough and can only be destructed by time & button battery failures. Working range maybe 100ft thru the alu siding of the house so it can catch me even if I'm on the rider trying to control my jungle.
