What is the calling and distress frequency on a single side band?

The radio frequency 2182 kHz is one of the international calling and distress frequencies for maritime radiocommunication in a frequency band allocated to the mobile service on primary basis, exclusively for distress and calling operations.

What are US calling frequencies?

146.52 MHz
Across all of North America, the National Simplex Frequency (also referred to as the calling frequency) is 146.52 MHz. In areas that use 15-kHz channels, the adjacent channels are 146.535, 146.550, 146.565 MHz, etc. moving upward. Below the calling frequency are 146.505, 146.490, 146.475 MHz and on.

What are the two frequencies that commonly used for distress urgency and safety?

The frequency band 406-406.1 MHz is used exclusively by satellite EPIRBs (emergency position indicating radio beacons) in the Earth-to-space direction. The frequencies 161.975 MHz (VHF-CH AIS 1) and 162.025 MHz (VHF-CH AIS 2) are used for AIS search and rescue transmitters (AIS-SART) in search and rescue operations.

How many HF frequencies are available for DSC distress related calls?

MF/HF DSC devices monitor multiple distress, urgency and sécurité bands in the 2, 4, 6, 8, 12 and 16 MHz bands. At minimum, controllers will monitor 2187.5 kHz and 8414.5 kHz and one more band.

What is the international distress signal?

The international emergency sign for distress is three of any signal: three shots, three blasts on a whistle, three flashes with a mirror, or three fires evenly spaced. If you’re near an open space, walk an X in the snow, grass, or sand. Do not light signal fires until you hear an aircraft.
