- Jan 3, 2012Matthew:I can think of a few legitimate uses for HSMM too, but the list is very short and in the majority of cases there are existing amateur radio systems that will do the same thing - much better - with less expense and complexity.It literally boils down to a solution desperately searching for some kind of problem to address. This desperation has created some humerous moments, like the time I was told about an amateur radio HSMM network that was going to provide national coverage. - I've heard that one several times, believe it or not, and I always get a giggle out of the cluelessness it highlights.Laws of Physics or Economics? - They have no jurisdiction over imaginary HSMM applications! ;-)The fact is that HSMM is an obscure offshoot of amateur radio that revolves around experimentation and discussion. It's great for those who would far rather 'imagine' than actually 'do' something. There are rare instances where a determined individual has demonstrated some practical bent with HSMM technology - but so far mobody has demonstrated a practical use for HSMM that does an amater radio job that is generally recognized as being needed to be done, and does it with less expense and complexity than that of existing systems. This has literally never occurred.HSMM lost the popularity contest, so to speak, quite some time ago. After several years of the ARRL utilizing all of its considerable resources to promote and hype the ARRL HSMM group out the wazoo in every issue of QST, the amateur radio community responded ( where they bothered to respond at all ) with a great big yawn. Then one day the ARRL HSMM group was mysteriously no longer there, dead without even a whimper. Needless to say, the strident ARRL HSMM hype in QST evaporated at the same time.There is a lesson there for those who 'imagine' that HSMM is suddenly going to become relevant today on the say-so of a few disgruntled enthusiasts.Calls to create more infrastructure to fail for emcom use with HSMM systems are not going to go very far, as the smart money on emcom today is to back up infrastructure that tends to fail, not attempt to develop systems that ( Duh! ) require more of it.Mobile, flexible, ad-hoc systems that can pop up anywhere at a moments notice by utilizing software and methods that amateurs are already coversant with - and do not have a steep learning curve associated with them - are recognized as being most effective and most useful in an actual emergency. This pretty well leaves HSMM's emcom usefulness on the same 'imaginary' level that characterises HSMM's usefulness in a general sense.In your reply, you stated that you could think of "a number" of amateur radio uses for HSMM. Then you went on to note two... VOIP links are the only application that you could suggest with confidence - but exactly how many amateurs do you see going to all of that additional expense and complication when they can just use the internet for VOIP linking?If you are not limiting yourself to VOIP, there are existing repeater linking systems that do a much better job, on a much larger scale, with much less expense and complexity. If we put on our thinking caps for just a moment and realize that most repeater linking is done to cover relatively long distances, one must wonder at the thinking that would seriously suggest SHF radios for that kind of application.Once again:Laws of Physics or Economics? - They have no jurisdiction over imaginary HSMM applications! ;-)The VOIP repeater links actually in use are generally done via the internet crutch in order to realistically hope to cover the distances involved. thus setting back amateur radio repeater linking by decades. Progress in actual amateur radio technology is thus retarded, not advanced by the alleged 'advance' of VOIP linking.So we are still waiting for a single practical demonstration of something both useful and desired - that HSMM can do better, cheaper and simpler than existing amateur radio systems.By "practical demonstration" I mean something that a significant number of amateurs have found to be useful and successful. - Not the rare exception to the rule that may exist through the fevered clambering of an ingrown sub-community of frustrated cranks.I suppose John Lennon must the be patron saint of HSMM.Imagine...You have to be good at imagining in order to be a HSMM enthusiast - as the practical applications are simply not there.73 DE Charles, N5PVL----- Original Message -----From: Matthew PittsSent: Monday, January 02, 2012 8:43 PMSubject: Re: [BPQ32] HSMM-MESH
I can think of a number of them; VoIP links, file sharing during emergency operations (not sure if this would actually work), and other things that need larger amounts of bandwidth than what current data modes can offer. Power output can be boosted with amplifiers, since the modified units operate in the 1.2GHz ham band and they can be fitted with directional antennas if needed. I'm going to be buying a few of these myself and testing them at various Emcomm events here in Ohio this year.
