Reducing RF Noise on Ships and Other Vessels Plying on Water

Communication on ships, boats and other similar vessels mainly is in the form of radio frequencies. But it happens so many times that the radio signals do not get transmitted in a smooth manner. Such poor communication might be caused due to RF noise, which is an interfering presence of frequencies that permeate the path of the original ones. Several complaints from sailors and boatmen commonly occur over not being able to communicate messages properly (Ocean Navigator, REDUCING RADIO NOISE AND INTERFERENCE, 2017). Poor communication over radio might cause misunderstandings, which is especially not welcome during dire situations. To avoid this, the people in charge of radio communications need to have a basic understanding of RF frequency interference and know how to reduce it by simple ways. The following points elaborate on this subject.

Applying Chokes

Radio signal interference may occur as a result of leaked radio signals that make their way into the battery cases. These signals might travel along the power conductors and if they enter the circuit breaker panels, a coupling effect may be produced on other instruments in the vessel. This may highly affect communications as well as ship and boat operations. For resolving such issues, a device that restricts the spread of leaked signals can be used. These devices are called chokes and they suppress any radio frequency signals that get interfered with the power wires (dieselduck.info, RADIO FREQUENCY INTERFERENCE, nd). This also does not cause any effect on Direct Current (DC) electricity sources. The radios can also be tested using a RF noise generator machines after applying the chokes to see if the system is working properly. These generators intentionally produce noise, which is mainly used to test equipment that operates on RF frequencies.

Clean up for a Better Signal

The is an important task that needs to be carried out for transmitting as well as receiving smooth radio signals. The radio antenna should be free from tangled wire coils, which can help streamline the signal frequencies. It is essential to clean the antenna part and other ground connections. It is better not to leave any antenna clamp loose. Improperly set up antenna terminals should be connected properly. The antennas should be periodically inspected for rusting and such deteriorating conditions. The batteries should also be changed regularly. Another way involves cleaning up the radio’s overall output. This is possible by reducing the output power. If radios are used on higher frequencies, they might suck in more power, which increases the likelihood of interference.

For ensuring smooth radio communication, indentifying the RF noise source, using RF shield and proper grounding are some factors that need to be considered. Apart from maintaining solving radio interference issues, it also is necessary for proper maintaining radar communications systems on ships and boats. Using a radar performance monitor is one way by which the systems can be tested.
