New radiobeacon monitoring instructions were prepared by the Communications Officer together with a communication chart for reporting radiobeacon failures, and showing all teletype, land line or radio connections in the District. A neon light bulb was installed in the pilot house of the COLUMBIA RIVER LIGHTSHIP as a visual check of the radiobeacon. The Quartermaster was instructed to check the timing every half hour.

The instructions for monitoring, as set up by the Communications Officer, were an improved revision over earlier procedure. Defective operation was determined to be:

(a) Incorrect timing in excess of five seconds.

(b) Improper frequency plus or minus .01% of the assigned frequency.

(c) Lack of tone modulation.

(d) Slurred or broken characteristics.

(e) Increased number of characteristics per minute.

(f) Sub-normal signal strength.

(g) Continuous operation for calibration purposes during the regular operating periods.

All previous instructions conflicting with the new regulations were cancelled. The District Coast Guard Officer further instructed that radio technicians be assigned only to such duty as that for which they had been trained and were not to be used in any other capacity. Commanding Officers were instructed to see that these assignments were carefully made.

Although radiobeacon alarm units were issued by Headquarters for installation on District radiobeacons, they had not been found completely successful. A radiobeacon alarm unit was improved by Chief Radio Technician D. W. Reid and was installed at West Point for thirty days' trial under Headquarters' authority. During this trial, the radiobeacon alarm unit proved successful as no failures were reported. As a result, Headquarters requested that a similar unit be forwarded to Norfolk to be tried there. No results of the Norfolk trial were received from Headquarters but the unit at West Point was still working successfully.
