"Frequency modulation radio service, an accomplished fact before the war, will be expanded to bring this noiseless reception to listeners in every metropolitan center across the land.
Radar Work Aids Television
"Our war-paced engineering and production of radar will yield proportionate advantage for television, its scientific first cousin. All answers for a completely satisfactory black-and-white television service already are at hand and war-learned lessons will speed development of improved color television."
Mr. Evans sees shortwave playing an increasingly important part in world affairs after victory with international shortwave stations fostering mutual understanding and good will among nations.
"The war has taught us that these long-range stations, which know no barriers of geographical frontiers or racial prejudice, can become powerful adjuncts of every nation's State l)epartment or Foreign Office. Hitler and Hirohito demonstrated their maximum abuse. It is tip to post war planners to shape this force to maximum good among nations.
High frequency heating, the electronics science's newest contribution to better-quality-at-lower-cost manufacture, also will reflect war developments in its post war applications, Mr. Evans said.
"Aided most by shortwave development will be its dielectric applications which have to do with non-conductor materials," he pointed out. "Already used to bond plywood, cure plastics and dry nylon yarn, this newest tool of industry will find hundreds of new opportunities to improve production and reduce costs for post war manufacturers.
"Also benefiting from the lessons of war production will be induction heating which is not dependent upon ultra-high frequency operation. This wonder process which has been reflowing tin, at a saving of up to 6 5 per cent. of this war-scarce material, will provide new and dependable manufacturing shortcuts in heat treating metals, annealing electrical steels, brazing and welding and many other essential shop operations."
