I feel a few things need to be addressed for part 15 am to work effectively in today’s harsh environment.

I feel a few things need to be addressed for part 15 am to work effectively in today’s harsh environment.

While i agree there needs to be a change of the rules for part 15 antenna length and possibly grounding, these changes may or may not help our cause if the problem of interference on the am bcb is not addressed as well.

Not only addressed but handled with extreme prejudice.
Today and for the past 10+ years advancements in technology has brought with it more and more interference on the am and sw bands.

In some areas even Fm is affected by noise from several sources.
For example: I subscribe to Road Runner High Speed as well as Time Warner Cable t.v. but with these conveniences come sacrifices, not only my money(lol) but interference on am/fm radio’s.

I know this because we have turned off our services before and the noise was almost non-existent unless you step outside with a walkman or boombox and maybe walk across the street to where the lines go from the pole into the conduits underground.

This noise is everywhere the power lines or cable tv lines follow the roads or is following the property lines of home owners up and down the roads of London,ky.
Also noise from fluorescent lights, digital gas pumps, street lights, leaky cable lines, power lines and much more. These things mentioned above are everywhere. Have you ever tried to to listen to any radio station while parked at a gas station?

Those pumps and lights put off so much hash , listening to a radio is pointless unless you are close to a high powered radio station.
6 years ago when I was heavy into CB Radio i had this complaint about gas stations and dollar stores, the noise blanker on my Grant Xl was worthless, i could transmit but forget receiving.

Something needs to be done to limit or even eliminate this noise now before it get’s so bad that radio is considered useless.

I can remember back when i was in vocational school towards the end of the 80’s and early 90’s i had a 35-in-1 Heathkit setup as a AM Broadcast Station and was transmitting 1/4 mile clearly.
It was on 1610 khz and I listened to it at as a friend of mine let me hear it over his phone, noise back then was limited to the usual suspects, mother nature and the occasional noisy light switch.

The point is, I could hear the signal 1/4 mile away and all i was using was a ground wire attached to the outlet in my room and a Buick car antenna (telescopic kind) on battery power.
My audio source was a tube type Webcor Reel – to – Reel and a make-shift matching transformer.

Just try that in the city these days and see how far it gets you.
I’m not against re-vamping the part 15 rules for am antennas or sorting out the grounding issues, but in order for low powered am to work, the noise needs to be removed or controlled more closely.

I would think this would fall under Spurious Emissions and if not, then it should be considered that from now on.
