In a battle war situation - the last thing a operator military person needs to have to do, is dial in an exact frequency. I suspect this was one reason for crystal control. Also in secure comms nets - periodic crystal changes, would make code book syncing net frequency very practical and reliable. By definition, in the military, all radio operators - where war fighters first.
Does anyone remember Gabriel Heater? When I was a kid, out at my grandparents cottage south of Buffalo - everyone used to sit around the Philco radio - and listen to Gabriel Heater's news program, at that time about WWII. "..... and all the ship's at sea". 73, de Fred N3CSY ...just got a TH-F6A toy, should keep me busy, till K3 arrives :) ____________________________________________________________________________________ TV dinner still cooling?
