No flames here, Mark, Maybe we should have stuck with straight keys - those bugs might obscure transmissions - maybe a 10 wpm speed limit. But no, folks added microphones and heising coils. Next thing the cans went to the sideline and there were loudspeakers, then Central Electronics with the multiphase exciter, and here comes sideband and warbulators....2M and 6M AM gave way to fm - point being this should be progress - just as digital has surpassed almost every analog strong hold.
Your telephone network has used PCM digital mux since the days of N Carrier went away - remember LD calls with cross talk in the back ground - gone. Digitized voice is in its infancy in ham radio, but I do believe with continued development it will continue to gain acceptance. I am not so big on critical traffic on ham radio - that is what public safety networks are for. We as hams provide comms for events like marathons, parades, etc, and during disasters, augment failed and downed public systems. Critical traffic is not intended to be hams mainstay. - kind of off topic for repeater builders, though. As for serviceability I have been a bench and field tech since 1972, when selenium rectifiers stunk, and tuned lines were king. We could actually repair radios then. Today, unless you have hot air soldering / desoldering stations and a microscope, I defy the average tech to get into board level repair - has nothing to do with digital, or smarts, or education and everything to do with automated manufacture and unbelievable reliability. It was unusual to see a tube radio in a butane truck go 6 months without some kind of failure. Now it's unusual for a modern radio not to outlast several butane trucks - things have changed. Our technology has changed too - the diddle stick is replaced with digital pots and firmware upgrades - flash new data and go. The really sad thing is my profession is also fast disappearing - 2 Way Radio Shops are turning into dinosaurs - we still change mics and volume controls and do minor repairs - but most major fixes go to a depot because who buys several thousand $$$ in custom repair and testing fixtures to change a 128 pin IC that cost $20 and fails in 3 out of every 500 radios in the first 2 years ??? So, no flames my friend - I too don't like all the change taking place but like a wise friend once said "a bend in the road is not the end of the road, unless you fail to turn." 73, Steve NU5D n9wys wrote: > Gentle people, > > Although I'm usually very open to newer technology, this digital (or better > said, "digitized") voice thing has me very concerned.
