All stations using 2182 kHz were required to maintain a strictly enforced three-minute silence and listening period twice each hour, starting at h+00, h+30.
and 500Khz….
Silence and listening period on 500 KHz between h+15 and h+18 and from h+45 to h+48.
S.P’s on 500 Khz were 15 to 18 minutes and 45 to 48 minutes past the hour. On 2182 it was on the hour and half past the hour .
500kHz 15-18 & 45-48 minutes past the hour
2182kHz 30-33 & 57-00minutes pst the hour
