"Doug Dotson" dougdotson@NOSPAMcablespeedNOSPAMcom wrote "Jack Painter" wrote in message news:WeKFd.16260$B95.1392@lakeread02... . As far as bandwidth for prevailing conditions, there are quite sufficient bandwidths available in the Maritime Mobile Service. Below is a little paraphrased version of the new guard frequencies. Duplex is now history for all hailing and distress work with the USCG. What does bandwidth have to do with this. The bandwidth of an SSB signal is the same regardless of the frequency/band used. Doug, k3qt s/v CAllista Doug, It was a little Freudian slip, sorry. I was describing the more than sufficient "bands" that are available, and the context of the message surely was clear to that. I note that you nonetheless repeated pretty much the same information of my message in your answer. I'm sure glad you cleared that up before everyone thought bandwidth meant bands! G As to the comments you actually added, such as 2182 khz not being reliable or used any longer, 2182 khz is most certainly used as a distress and hailing frequency to raise the USCG, where it is monitored from every USCG Group, even in places like the Mississippi River where it has completely fallen out of use due to cell phones, which are never out of coverage in that area. Using equipment with considerably longer range capabilities than USCG Groups have at their disposal, I have never heard a call go unanswered in over six months of dedicated guard on that frequency. Many MAYDAY calls were answered by several USCG Groups at once. While I would hope we can continue to improve the quality of equipment available for this work, it is in no means incapable of doing the job that is expected of it. It is not likely, in my opinion, that satellite phone links or vessel and personal EPIRB's will ever completely replace HF emergency communications. If these newer and more capable equipments do render the average yachtsman or mariner less familiar with his HF equipment and capabilities (due to infrequent usage) then that is an issue that can be addressed in boating safety and professional standards courses. It would be too bad to see such capable means of communication lost to just an aging part of the hobby field, do you agree? Jack Painter Virginia Beach, Virginia |
