SSCA Marine HF and VHF Resources



For all the networking tools we have, there is nothing like the live party line excitement of a radio network. The HF nets are a great radio check and a source of camaraderie.


SSCA encourages the use of marine HF radios for the pleasure of communicating live with other cruisers in the same waters, beyond VHF range. Offshore, agreed HF frequencies used by rallies are fun and an important source of info on nearby weather. And it is fun!

Like the VHF radios we use all the time, HF radio is also an excellent way to coordinate emergency assistance offshore.


SSCA encourages cruisers to discover and use Near Marine HF and VHF nets. SSCA has also long supported Long Distance nets.

Near Marine HF Nets – 200-400 miles at 4mHz, 400-600 miles at 6mHz

These nets reach beyond VHF to cruisers in a region such as Maine, Chesapeake Bay or Eastern Caribbean. The range is good for keeping up with friends and exchanging info about local weather, safety and entertainment. To reach cruisers further away, see Long Distance Nets below. Near Marine HF Nets


Local VHF Nets – Up to 20 miles at 25 watts, may operate at 1 watt to be good neighbors

Check marina bulletin board. Ask on the dock. Some that we know: Local VHF Nets


SSCA is looking for opportunities to support local short term VHF nets such as the Norfolk Harborfest in early June. We are able to provide local marine and event info through our HAL ChatGPT. If you are interested in volunteering, please contact us at office@ssca.org.

 

Long Distance Nets – 8 and 12 mHz marine and 7 and 14 mHz ham HF


Nets typically start by asking for emergency and priority traffic, then position reports from vessels on passage, vessels recently arrived, and finally any boat-to-boat traffic which may continue after the net formally closes. Boats often share local conditions and boating news. Most important, calling in gives cruisers a radio check. Long Distance HF Nets

 

“Mic fright” is real! But treatable. Practice using your “rig” by calling in to nets. Net controls keep logs and will see you are new to the net – and they will welcome you. The custom is to give first name and boat name or first name and ham call sign on ham frequencies.

Set up you own net schedule for a rally. 

Key is to agree in advance time and frequency (and alternate frequency).

Opposite is an excellent example. 

Note that the rally was so large that organizers had two nets.

To enter a frequency on an M802:
Press Clar/RX button and enter frequency with CH and GRP knobs. Be sure top line of screen shows USB. All marine HF frequencies are USB. If screen does not show USB, press SET/Mode to cycle to USB.
Press TUNE button. Listen. If frequency is clear, you can say your boat name and location and "radio check".

To enter a frequency on an M803:
1. Select a channel that is programmed with a frequency near the frequency you want to receive.
2. Push [RX/TX] to select the RX mode.
• The RX icon lights blue.
3. Enter the desired receive frequency using the 4 arrow keys or numeric keypad so 08152.0 for 8152kHz.
For normal Simplex operation, there is no need to set a transmit frequency.

To check reception:
1. try the time frequencies which should be programmed as WWV: 5000 kHz, 10000 kHz, 15000 kHz, 20000 kHz.

2. try the USCG working channels for weather: https://www.weather.gov/marine/uscg_broadcasts
See at bottom of this page an excerpt from the table.
The times in Zulu aka UTC so subtract 4 hrs during EDT, thus 1115Z is 0715 EDT.

3. You are encouraged to do an automated DSC radio check with, by example, USCG Norfolk on 4207.5 kHz. See SSB DSC Test Calls
