What is MF 2182 kHz?
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 kind of emission class is best suited for 2182 kHz?

Does the Coast Guard monitor 2182?
The Coast Guard keeps watch on the Global Maritime Distress and Safety System (GMDSS) SSB-HF frequencies 4125, 6215, 8291 and 12,290 kHz in place of the old international radiotelephone distress frequency 2182 kHz, Olsen said.
What is the frequency of very high frequency?
VHF, in full very high frequency, conventionally defined portion of the electromagnetic spectrum including any radiation with a wavelength between 1 and 10 metres and a frequency between 300 and 30 megahertz. VHF signals are widely employed for television and radio transmissions.
What is the frequency range for very high frequency?
30 MHz to 299 MHz
Radio frequency range from 30 MHz to 299 MHz. The sub-bands most commonly used by fire are: VHF-FM Lo band: Frequency Modulation 30 MHz – 80 MHz, of which fire frequencies are between 30 MHz and 50 MHz.
What is the range of MF HF?
Typically Marine MF/HF-SSB radios operate in the frequency range of 1.6 MHz to 30 MHz.
Where can I use extremely high frequency?
Extremely high frequency (EHF) waves can carry an enormous amount of data and find wide application in radar, simple-type terrestrial communications, and satellite communications.
What uses very high frequency?
In addition to VHF broadcasting, very high-frequency radio waves are widely used for ship and aircraft communications, disaster prevention and administration radio, police and fire radios, ham radio, and other applications.
What is range of very high frequency radios?
Is UHF or VHF better?
VHF radios are suited for long distances in and outdoor use. UHF radios operate at a higher frequency. This makes them ideal for wireless communications that need to penetrate through buildings, walls, or concrete. UHF radios are suited for indoor communication solutions, where obstacles are easily penetrable.
What is the difference between MF and HF?
Medium Frequencies (MF) designated for marine communication range between 1605 kHz to 3800 kHz and are called “t” band. High Frequencies (HF) designated for marine communication range between 4000 kHz to 27500 kHz and are called “u” band. Only the first five are used for distress and safety communication.
What is the Morse code frequency 2182 kHz?
2182 kHz forms an essential part of the Global Maritime Distress Safety System (GMDSS). It has an associated DSC frequency at 2187.5 kHz. Other international distress frequencies, in use as of 2008, include: 500 kHz Morse code is no longer monitored.
Which is the international distress frequency 2182 kHz?
2182 kHz forms an essential part of the Global Maritime Distress Safety System (GMDSS). It has an associated DSC frequency at 2187.5 kHz. Other international distress frequencies, in use as of 2008, include:
What is the DSC frequency of 2182 kHz?
2182 kHz forms an essential part of the Global Maritime Distress Safety System (GMDSS). It has an associated DSC frequency at 2187.5 kHz.
When did the Coast Guard stop using 2182 kHz?
Effective 1 August 2013, the U. S. Coast Guard terminated its radio guard of the international voice distress, safety and calling frequency 2182 kHz and the international digital selective calling (DSC) distress and safety frequency 2187.5 kHz. Additionally, marine information and weather broadcasts transmitted on 2670 kHz terminated concurrently.
