NY gets a new Exband AM

ai4i said:
Graveyards were called class D's. Regionals were called C's. If a station at a certain distance is half a watt and a much closer station is also half a watt, and the closer one overpowers the farther one by 20db but then they both increase to one megawatt, one million watts, the closer one will overpower the farther one by the same 20db at the exact same place, but they will each be 63db stronger within their own respective areas.

Absolutely true about the VHF aircraft Com band.

Class B are Regionals....Class Cs are 1 kw omni day/night and were meant to be "local" stations...but soo many are on the channels, it is a graveyard now; hence the name..Class Ds are daytimer only or flea power at night..
 
New cars don't have AM radios unless you want it as an option.

How many cars don't have AM as standard? I just bought a new Ford, it has AM, along with FM and satellite. No HD, although I think that's available with the upgraded system.

I was surprised how good the AM is on my Ford, better than on my old Chrysler.

I know of exactly one model of one brand that has no AM radio... The $80,000 BMW electric.

And that's only because the electric motor completely wipes out AM reception.

I was just going to ask about how electrically noisy electric and hybrid vehicles are. Miami-Dade County, Florida had or has a bunch of pickup trucks driving around with beds full of batteries.

I have a hybrid, and it has no difficulty with the reception of AM stations on its standard radio / audio system.

From what I have read, the noise issue is confined to some proprietary systems unique to the BMW all-electric model.

Funny, when I drive the 2007 Toyota Prius, FM reception, which is fine when engine/motors are not running, is marginally harmed when I drive (though I can still listen to strong local FM signals), shortwave bands, as well as 6m (50MHz), low-VHF TV (54-88 MHz) and 2m (144 MHz) are all but obliterated when driving, with noise especially heavy whilst coming to a stop, but the AM band is completely unaffected! Reception down to .1 mV/m is good, whether the car is moving or not (surprised the H377 out of me, too!)

You need to do some research. In 1990 there were 4,987 AM stations in the USA. As of late 2009: 4,790. By late 2013: 4,728. I don't have 2014 totals, I've been told to expect at least another 14 deletions.

Given the combined realities of AM core audience reaching mortality and the one viable mainstream talk format; sports slowly migrating to FM, it is fair to expect the declines to accelerate.

So about 200 AM stations going dark in a 25 year period? THE SKY IS FALLING!

I'm not a car expert. All I know is BMW made a special radio for this car and couldn't put AM on the radio because of the engine.
