4. 29mHz cordless phones. Do any still exist?


I don't remember any cordless at 29 MHz. As I recall, the first cordless
were 1.8/49 MHz (you could buy antenna kits with a long wire for base
transmit. We could get around a 4-5 block range with those). Second
generation went to 46/49 MHz, and could be heard on many cheap baby
monitors.
