NOTES: LNS notes: This tape was off speed and originally recorded first at 3 3/4 ips for the first portion of the voice announcement and then 7 1/2 ips for the remainder of the voice announcement and the entire recording. The playback speed for archival was 4.02ips for the first secion, based upon the recordist's 440Hz calibration tone, and 8.02ips for the 7 1/2 ips section based upon this same calibration tone. Heavy thumping in the recording is due to cable noise.
