Most of the... difficulties ordinarily in volved in picture reception work will be pre vented because manufacturers will supply equip ment especially designed for the purpose and if the experimenter understands the principles of the system and can handle amplifier and oscil lator circuits, he should have no di¿iculty in setting up his Rayfoto recorder and having good picture reception right from the beginning.
