The limitations of VHF radio are obvious to all of us, so there's no need to repeat them here. And I'm suggesting a move up to SSB or satellite telephones. Surely, there is a better way to handle boat to boat or boat to shore communciations, with features like duplex, much greater range, less static. Right? VHF vs. Satellite phones: VHF can send a general broadcast, such as a pan pan or a mayday. Satellite phones need to know what number to dial in order to reach some boat across the harbor. One of the primary functions of the radio is to enable a boater to call for help in an emergency or respond to a call for help from another boat- removing the general broadcast aspect from communications capability defeats that function. SSB: SSB signals carry a very long way. Wouldn't the airwaves become so jammed as to be entirely unworkable in busy areas? As it is now with VHF, especially set on "low", you can be using a frequency in one location and somebody else can use the same frequency 15 or 20 miles away and you won't interfere with one another. I could be wong, but I think there are specific reasons why VHF is the preferred technology for short range transmissions in crowded areas while SSB is more popular for vessels well offshore and requiring extended range. There's no reason you couldn't put a satellite phone on your Parker and use that *instead* of a VHF for a lot of communications needs. My error. I meant to type ... NOT suggesting a move up to SSB or satellite, just for the reasons you mentioned. |
