What VHF channel is Coast Guard?
Any vessel in distress should use Channel 16 VHF-FM (which the Coast Guard does monitor). Channel 22 is the most common working channel for USCG in the event of an emergency. The following list of channels are those available in the United States for VHF Radio communications.
What is the frequency of Channel 16 VHF?
VHF Channel 16 is the international distress frequency; it broadcasts on a frequency of 156.8 MHz and is received worldwide by any VHF radio.
What radio frequency Do ships use?
If you have radio telex, your ship’s transmit frequencies are: 2 502, 4 173.5, 4 176, 6 271, 8 388.5, 12 498.5, 16 692.5, 22 316. Non-SSB (i.e. Broadcast Stations’) ‘Time’ signal are on 2.5, 5.0, 10.0, 15.0, 20.0, and 25.0 MHz at various times of day.
How can I listen to the Coast Guard?
The proper way to undertake a radio check is to contact the coastguard on the appropriate channel. In the Solent area Channel 67 is used. Check your almanac. If you want to call the coastguard on the calling channel use CH16, although they’ll probably send you to CH67.
How far will a 25 Watt VHF radio transmit?
For example, a 25-watt marine radio will roughly have a maximum range of 60 nautical miles (111 km) between antennas mounted on tall ships, but that same radio will only have a range of 5 nautical miles (9 km) between antennas mounted on small boats at sea level.
Do CB radios use UHF or VHF?
These services began in 1945 to permit citizens a radio band for personal communication (e.g., radio-controlled model airplanes and family and business communications). In 1948, the original CB radios were designed for operation on the 460–470 MHz UHF band.
What VHF frequencies can I use?
The general services in the VHF band are:
- 30–49.6 MHz: Licensed 2-way land mobile communication, with various sub-bands.
- 30–88 MHz: Military VHF FM, including SINCGARS.
- 43–50 MHz: Cordless telephones, 49 MHz FM walkie-talkies and radio controlled toys, and mixed 2-way mobile communication.
Is marine VHF AM or FM?
It uses FM channels in the very high frequency (VHF) radio band in the frequency range between 156 and 174 MHz, inclusive, designated by the International Telecommunication Union as the VHF maritime mobile band.
Why does Coast Guard say Pon Pon?
A pan-pan call is warranted to attempt urgent radio contact with an approaching vessel that may be in danger or is approaching a dangerous close-quarters situation that would risk collision. If the vessel is heading to shore and wants an ambulance crew at the dock, the local Coast Guard station can arrange this.
How far can VHF transmit?
A typical VHF station operates at about 100,000 watts and has a coverage radius range of about 60 miles. A UHF station with a 60-mile coverage radius requires transmitting at 3,000,000 watts.
What is the frequency for distress safety and calling?
156.8 MHz: International Maritime Distress, Calling and Safety Frequency. 243.0 MHz: NATO Combined Distress and Emergency Frequency.
How can I get a free MMSI number?
U.S. Non-Federal User Mariners not required to carry a marine radio (e.g. recreational boaters) and who remain in U.S. waters can obtain an MMSI through approved organizations such as BOAT US 1-800-563-1536, U.S. Power Squadron, and Shine Micro (primarily for AIS).
Do I need a Licence for a VHF radio?
Anyone who uses a Marine VHF Radio needs a licence. If you need a radio, you may need both a radio licence and an operator’s licence. This depends on the type of radio you have and how you use it. Once installed in a vessel, a marine VHF radio requires a ship’s radio licence.
