   working frequencies at intervals of:

   (1) In the case of telegraphy, at least two hours and not more than four
   hours during the working hours of the coast station.

   (2) In the case of radiotelephony, at least one hour and not more than four
   hours during the working hours of the coast station.

   they are about to transmit call lists on a specific working frequency.
