Possible 'Pirate' Radio Station(s)?

GMDSS System Global Maritime Distress Signal System, SOLAS requirement

VHF-FM Radio Marine Band 156-158 MHz SOLAS requirements to maintain a listening watch on distress frequencies

Coordinate small boat activities around SeaStead, each small boat equipped with one of these too.

Relatively small radios, low power (~25w ERP), small antennas (2 meters or less in length, max. Handhelds ~8" long)

VHF-AM Radio Aircraft Band 118-136MHz

Coordinating air traffic inbound and outbound.

Several frequencies: Departure/Approach, Tower (landing), Ground (ground movement), coordination frequencies

Air Traffic Control radar

Air Navigation aids? VOR/DME/ TACAN or rely on GPS?

"Company" radios for SeaStead operations, similar to business-band frequencies (VHF-FM High at 150MHz or UHF-FM at 450-470MHz and/or 800 MHz trunked system. Will probably require robust encryption.
