Sec.  80.108   Transmission of traffic lists by coast stations.

   (a) Each coast station is authorized to transmit lists of call signs in
   alphabetical order of all mobile stations for which they have traffic on
   hand.  These traffic lists will be transmitted on the station's normal
   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.

   (b) The announcement must be as brief as possible and must not be repeated
   more than twice. Coast stations may announce on a calling frequency that
   they are about to transmit call lists on a specific working frequency.
