Cruiser's Maritime Mobile HF Nets (Times and Frequencies)

Because HF Radio operates over a longer range than VHF Radio it is highly suitable for long range communication between groups of cruising sailors who may be spaced far apart over the oceans.

HF Radio Nets are set up, either on a permanent, semi-permanent, or ad-hoc basis by groups of cruisers, shore stations, and other groups in order to facilitate this communication over a specific geographic area and at regular intervals.

HF Radio Nets for marine use are set up and run by "controllers" all over the world (Indian Ocean, Atlantic, Mediterranean, Pacific, etc.) to handle and co-ordinate this traffic from vessels sailing the oceans. It is important for cruising yachts to know these radio net frequencies and times so as to pass message traffic, log positions, receive weather information, etc.

Be aware that HF Radio Nets are often ephemeral and change from year to year. As cruisers and other users drift away from some nets, others will spring up in their place. Any listing of HF Radio Nets therefore needs regular updating to be considered even approximately definitive.

Amateur Radio Net Listing

All times are UTC (Greenwich = Zulu = UTC) unless otherwise noted. Please listen first to note the procedures of each net.

Mode used is generally upper sideband (USB) above 7.300 MHz and lower sideband (LSB) below 7.300 MHz.

Marine Nets

All times are UTC (Greenwich = Zulu = UTC) unless otherwise noted. Please listen first to note the procedures of each net.
