In addition to the regular branch receivers with a 12-kilocycle bandwidth and the monitoring branch receiver with a bandwidth, two other receivers are provided in the experimental receivers have a 30-kilocycle band width and are used for pulsereception. They are bridged across the inputs of the two regularbranch receivers and are connected to a cathode-ray oscilloscopethrough a commutator.^ Various photographs of the MUSA receiver appear with explanatorycaptions in Figs. 16, 17, and 18. 362 BELL SYSTEM TECHNICAL JOURNAL.
