I know some of you have mentioned the fact that there's a loud low-pitched hum or buzz over the speakers when the radio is set to AM and the Pilot passes under high voltage power lines.

I listen to AM frequently, and unfortunately I often drive a road that has powerless right along the edge for miles. The hum is so annoying I have to switch to FM or CD.

Has anyone every come up with a fix for this? Aren't there interference filters that can be added between the antenna and the radio unit? The AM reception is solid otherwise.

This is the first vehicle I've ever owned that did this.:bsflag:

I'm surprised that this is your first vehicle that does this. I've never not had a vehicle do it.

am hum

I HAVE THE SAME PROBLEM. ANY TIME I GO UNDER LINES I HAVE THE LOUD HUM. I THINK IT HAS TO DO WITH THE ANTENNA. I ALSO HAVE SOME BREAK UP UNDER BRIDGES, ETC. I AM STRONGLY LEANING TO XM AS A SOLUTION. I JUST UPGRADE THE FRONT SPEAKERS ANS SUB BECAUSE OF THE POOR OEM UNITS.

You will find in any vehicle that is equipped with a AM (amplitude modulation) radio that it will be VERY prone to power line noise. Not a whole lot you can do about in the normal type vehicle or house consumer type radios. FM (frequency Modulation) type of radios do not have near the trouble by virtue of their modulation scheme. Run an electric appliance (i.e drill) near your car while listening to the AM portion of your radio and then do the same while tuned to the FM portion. IF AM station is strong enough it MAY overpower the noise so do the test tuned off a station.
If you really want to get into the theory of it, do a search on power line noise and its characteristics, just get a big cup of coffee!!
yes there are noise limiters that are used in some radios but not that I have seen in normal consumer auto/home radios.

The fix is easy.....listen only to FM stations.

Believe it or not, my Pontiac Montana's radio does not do this. Only once in a while and even then, the 'hum' is very low. But for some reason, the Pilot radio seems particularly susceptible to this "AM hum".

All vehicles are different, but my previous Chrysler and my wife's Toyota don't do this. Driving along the same road with the power lines along the side, you may notice a few crackels now and then, but not the constant loud hum.

I want to figure out a fix for this. Thanks for everyone's input.

Same problem here.

I have the same problem with the AM.

My Volvo 850 wagon, does not do that and has a crystal clear AM.
The wagon has the samilar type of antenna embeded in the cargo area window, and has an amplifer connected (OEM).

I complaint to the techanican at my 1st service, instead of checking for loose connection, he just debated with me it is the same situation with the cellular phone :confused:

Nothing has been done.

Yep, best it is the first with a sub-woofer!

All Am will pickup 60Hz hum, just most radios don't reproduce much below 200Hz.

Some one should have mades the Sub turn off on AM. :confused:

AM Radio

The last car I owned that did this near power lines was a 1971 Chevrolet Nova that I got rid of in 1979. Now that is saying something. The first time I drove the Pilot under a power line while listening to AM it brought back some good old memories, but there is no excuse for a vehicle having this problem in 2003. Personally I don't listen to AM much so it's not a problem for me. If I did listen to Am I would be P O'd big time.

Its not an excuse, it is the nature of AM.

Radio buzzes when going under hi-power electric line

Just took delivery of my 2004 Pilot on 10/14/2003. It's an EX-L equipped with the 6-disk CD Changer (under-seat).

I noticed on my way to work at the nuclear power plant the next day, that when I drove under the High Voltage (500KV) output power lines while playing the radio, that there is a bunch of static & buzzing noise played thru the speakers until I get out from underneath the power lines.

I also noticed this occurring on my drive home as I passed beneath power lines of lesser voltage along the highway. My previous vehicle didn't do this.

Is this static / buzzing sound normal?
Is there anything that can be done to reduce the static?

Actually it was Steely Dan, Stealy's brother.

Ok, So after reading thru this entire thread, the bottom line is that there isn't anything that can be done to the Honda AM Radio system to minimize the buzzing? That we should just live with it, listen to FM, Tapes, or CD's, and be grateful we have such a nice vehicle? :roadtrip:

Does that sum it up?
