NO NO NO NO NO NO If they must do this thing, and the government deems it necessary, let the government give them 20 KC of the government assignments and least the ham bands to hams.  The goovernment use of the HF bands has diminished considerably over he past 40 years, and they have it to spare.     ----- Original Message ----- From: Joe Ivey To: digitalradio@yahoogroups.com Sent: Wednesday, February 22, 2006 11:05 PM Subject: Re: [digitalradio] Re: NTS and traffic handling and digital Doc,   It is just more B S from those that want to turn ham radio into an email server. What needs to happen is give those a 10-20 KHZ segment of each band and let them do their thing and if anyone else was operating in that segment would have no reason to complain about QRM.   Joe Ivey W4JSI   Age is mind over matter If you don't mind, it does not matter     ----- Original Message ----- From: doc To: digitalradio@yahoogroups.com Sent: Wednesday, February 22, 2006 8:03 PM Subject: Re: [digitalradio] Re: NTS and traffic handling and digital I would like to see the documentation of this. As a former employee of a state emergency management agency and a former section emergency coordinator and a Ham for a long time the scenario described must be missing some important variables. If HF Winlink could hold effective communications on HF then so could a dozen or more modes.  There is no technological reason why HF Winlink was "the only" reliable mode -- unless the modes chosen were skewed to be certain of that outcome. Not looking for an argument, just some healthy cynicism based on a little knowledge of politics and science. HF Winlink may have been "one of many" modes more capable of effective weak signal communications but one cannot ever make the claim that it would be the "only". Add to that the need for redundant hardware and the high value of simple over complex and HF Winlink would be a poor first/primary choice.  The hardware is so rare as to be readily postulated as "probably unavailable" at both ends and the complexity of the systems rise above standard emergency requirements for mission-critical applications. A third-tier or fourth-tier nice-to-have perhaps.
