Notes:

1) The International VHF Distress frequency was monitored (guarded) under normal conditions. If communication was required with aircraft, then another frequency would have to be selected.

2) The Administrative net would pass traffic such as:

- Notification of frequency changes among a force of ships.
- Items to be transferred by motor launch.
- Chatting. Although it was against regulations, the ships sometimes chatted with each other.
