quote author=Tom Wells By the way, why doesn't ibiquity have a director of damage-control or something to refute the "wild claims" and "opinions"?
_Probably two reasons; these hobby boards attract only the tiniest minority of the public and there hasn't been any public outcry over this system.
MAYBE ONE MORE REASON? THEY CAN'T REFUTE THEM BECAUSE THEY ARE TRUE?I'm sure they appreciate those of you who do try to make the best possible presentation on their position.
A rather snide remark.
SOUNDED LIKE A SINCERE STATEMENT TO METhose of us who find various faults to pick with HD generally do so out of love for the medium, the technology, and the desire to preserve the best possible
service in the manner we have enjoyed since the inception of radio.
AM is fighting for it's future, I grew up with high quality wideband AM that sounded often better than FM, the average person didn't and the last two generations are not interested in it. The audio is the reason.
OR MAYBE THE MANUFACTURERS STOPPED MAKING WIDEBAND RECEIVERS BECAUSE THEY COSTS 2 CENTS LESS PER UNIT TO MANUFACTURE AND RADIO DIDN'T COMPLAIN ENOUGH? I THINK WIDEBAND AM SOUNDS MUCH BETTER THAN FMI accept that NYC and its environs has a perhaps one of the, if not THE most challenging, difficult RF environments to be found anywhere.
Whether that justifies changing radio everywhere else in the country is debatable.NO
station is forced to adopt this system It was AM broadcasters who demanded via the NAB their inclusion in what was originally envisioned as an FM-only project.
I BET THEY RUE THAT DECISION NOW.I have long thought core-urban dwellers have needed central RF distribution systems inside buildings in the same way RF is provided in the Lincoln and Holland tunnels.
The problem with this concept is that residential buildings are not Faraday cages, a tunnel is after the first 50 or so feet. The "leaky conductor" that works so well there would find it's signal clashing with OTA. our building has this problem with it's CATV system and it badly damages some channels.
Most people put up with FM multipath unless it gets horrendous but even on the WPLJ aircheck that I posted you can certainly hear how after the first 6 sec the sound clears. No point in reiterating the issues with AM.The problem is two-fold. Signal attenuation could be dealt with, but modern electronic design with discontinuous current devices added to the picture is what has precipitated the noise problem. Shouldn't the NAB have gone after requiring meaningful compliance with pt 15 unintentional radiator rules?
Maybe so, but with ever fewer people listening to AM radio there hasn't been a public outcry and the NAB would have stiff opposition from other business and importers of this noisy junk.
WHY DOESN'T RADIO ITSELF COMPLAIN ABOUT THIS NOISE WHICH HAS GOTTEN SO BAD, RADIO DOES NOT TAKE CARE OF ITSELF, THE PUBLIC DOES NOT COMPLAIN FOR THE MOST PART, THEY JUST TURN TO OTHER METHODSBad engineering is bad engineering. A REAL rheostat generates NO NOISE whatsoever. All the "loss" becomes heat, not a "right angle turn" of the waveform,
which generates RF byproducts over a very wide spectrum.
You can't be proposing a return to rheostats! I'am old enough to remember the waning day of their use in Broadway houses. Six or more piano boards (size of an upright piano) each with 6-8 fully loaded 6-10-14 kw dimmers and their smaller preset boards, many of the cores showing color. An enoumous waste of energy a sweltering place to work. Much better are the autotransformers and mag-amps.
WHAT'S WRONG WITH RHEOSTATS IN HOUSES AND OTHER RELATIVELY LOW POWER APPLICATIONS?, DIMMERS RAISE HELL WITH RADIO
I've worked on over 170 productions, almost all used scr dimmers some of these shows were broadcast via WNCN radio and/or PBS tv, there was never any problem with professional light control equipment.I suspect those who want decent TV in NYC use cable. Such difficult RF environments need special treatment and measures.
To ask everyone, everywhere else to lower their expectations for radio is hardly acceptable.
Again, no one is forced to use the iboc system.
YES WE ARE, WE ARE ALL FORCED TO LISTEN TO IT'S INTERFERING SIDEBAND HASH WHETHER WE WANT TO OR NOT.
Those who are "on the bandwagon" really ought to get a check from ibiquity for their promotional assistance.
That's insulting. I'am personally not on anybody's "bandwagon" I have a low opinion of businessmen and their republican puppets.
If you want to assign blame for the state of AM radio..blame the public that has deserted it. IBOC is a tool offered to an industry in decline. It'll probably fail and the churches, preachers and other hucksters will then overtake your's (and mine) beloved medium.
THE PUBLIC HAS DESERTED IT BECAUSE MOST OF WHAT YOU HEAR ON IT IS JUNK AND IS HEARD ON JUNK RECEIVERS, I'VE OFTEN WONDERED HOW AM RADIO WHICH WAS SO POWERFUL 40 YEARS AGO LET ITSELF GET TO THIS SORRY STATE WITHOUT A FIGHT. EVEN REALLY GOOD RECEIVERS MADE AT LEAST FOR THE PAST 30 YEARS HAVE JUNK AM SECTIONS, WHY? AND MORE IMPORTANTLY WHY DIDN'T AM RADIO GET TOGETHER AND DO SOMETHING WITH MANUFACTURERS TO IMPROVE THEIR AM SECTIONS?
