Each line is one channel of the international maritime VHF channel plan: the channel number, the frequency ship
stations transmit on and the frequency coast stations transmit on, in MHz, or "-" where the plan gives coast stations
none (channels 06, 08, 72 and 77, ship-to-ship only). The values are copied as printed from:

  ITU Radio Regulations, Appendix 18 (Rev. WRC-15), "Table of transmitting frequencies in the VHF maritime mobile
  band", Final Acts of the World Radiocommunication Conference 2015, pages AP18-115 to AP18-117:

Cross-checked against the channel table of the English Wikipedia article "Marine VHF radio" (same values for every
channel listed here) and, for the ship frequencies, the US Coast Guard Navigation Center's VHF channel table.

Left out on purpose: channel 70 (digital selective calling, data only), channels 75 and 76 (guard channels either side
of 16, limited to low-power and AIS use), the single-frequency variants of the duplex channels (1019, 2006, 1078,
2078 and so on), and AIS 1 and AIS 2 (161.975 and 162.025 MHz, digital ship positions).

The app listens on the coast station's frequency where the plan gives one, since that is what a receiver ashore hears
on a duplex channel; on single-frequency channels both are the same. Countries may use some channels differently
(Appendix 18 notes), and channels 24 to 26 and 84 to 86 may carry digital (VDES) traffic in some areas.

Frequencies are facts of an international treaty table, not a creative work; no licence applies to them.
