Radio Facsimile Propagation Requirments
Two companion facsimile symposium papers, prepared by Messrs, Mathes and Smith and W. H. Bliss, treat the related subjects of propagation requirments and test apparatus employed in determining such requirments, and deserve carefull reading. Radio facsimile development based on like procedure will go a long way toward eliminating much of the guesswork which was planly evident until the latter part of the third decade of the thirties.
