What is an advantage of a cellphone over a VHF radio?
While both use high frequencies that are line of sight range only, the cellphone connects to a cellular network of transceiver antenna towers that are interconnected (via either landlines or microwave links) permitting cellphones at practically unlimited distances to communicate. VHF radios can only communicate when they can "see" each other (or both can "see" the same VHF repeater).
What did heinrich hertz do with the electromagnetic spectrum?

Where can the operator if a pleasure craft obtain marine weather forecast information?
The operator of a pleasure craft can obtain marine weather forecast information from several sources, including the National Weather Service (NWS) or the relevant meteorological authority in their country. They can also access weather apps and websites specifically designed for marine forecasts, such as NOAA Weather, Windy, or Weather Underground. Additionally, VHF radio broadcasts provide real-time updates on marine conditions, which are crucial for safe navigation. Lastly, local harbormasters or boating organizations may offer updated weather information tailored to specific waterways.
Does GPS satellite have the same frequency with AIS?
GPS Satellites use two frequencies 1.57542 GHz and 1.2276 GHz. AIS operates in the Marine VHF band using channels 87B, 161.975 MHz and channel 88B, 162.025 MHz
Weather forecasts particularly on the water can change quickly. What is the best method to monitor the weather while out on the water?
The best method to monitor the weather while out on the water is to use a combination of a marine VHF radio and a reliable weather app on a mobile device. The marine VHF radio allows you to receive real-time updates and alerts from the National Weather Service, while a weather app can provide detailed forecasts and radar images. Additionally, keeping an eye on the sky for changing conditions and having a plan for safe exit in case of sudden weather changes is essential. Always ensure that your devices are charged and have backup communication methods available.
