Having a problem,

Installed a new automotive radio (with CD, remote, and all the bells and whistles) in the upper front cabinet in or '74 - 31' A/S.

The AM radio signal will disappear from time to time and you hear a disturbing whine from the speakers.

Right now I suspect the radio is picking up interference from the new Xanex that replace the Univolt. I suspect this interference is from the Xanex because the weird whine occurs when the Xanex starts up to charge. Once the Xanex has done it's thing the AM signal returns.

Do we need a filter of some kind?

Anyone been there and done this?

Thanks.

Bob

Nairn,
I get the same thing while listening to coast to coast AM stations when I travel near high-powered electrical lines or sometimes when I pass tractor trailers (maybe CB interference). Not sure if there is much I can do since I am mobile.

In your case, is this a unit that has AM antena inputs or is it a car radio type with an internal antena?

If it has a place to plug in 2 wires for AM (most house units do), you can make a simple antena with wire and position it away from the interferance (see site below for making the antena). If it is a car radio and built in AM antena, the only thing that works is moving the radio away from interference or sometimes turning the radio may work but if it is mounted stationary, that will not work. I don't know much about filters but the article below mentions getting an inline filter that plugs in between the Univolt and the wall receptacle it is plugged into that may be able to help (really not sure on this though).

AM Radio Interference

The radio is a new 12 Volt automotive radio with AM, FM, CD, and MPD.
The aerial is mounted externally on the trailer. The PO changed the original aerial at some point (probably ran into a tree and broke it).
This noise interference is when parked and tuned into a known strong AM signal.
Thanks, Bob

Put in another stereo in our latest AS, this time there was not enough room for the components so I built a box for each.

Is that a hinge on the top of the speaker box. I am about to upgrade my speakers and have the material for the box. If it is a hinge, how did you secure the bottom.

mwells,
Not to answer for Nash but looking at the top 2 photos in post #33, it looks like 2 90 degree angle brackets, one at the top and one at the bottom, doesn't look like it's hinged. Can see the top one in the first photo and both in the second.

BTW - Looks good Nash and I bet it sounds great!

Bose system in 72

I bought a Bose/Onkyo Combo system from Sams. Put the receiver in the overhead bin (above the Vizio 2"LCD) and the speakers on the front panels by the door and kitchen. There weren't any previous speakers installed so I started from scratch. Of course the small Bose speakers are offset by the subwoofer module that also houses the crossover. I mounted it under the sink and bought a cheap plastic cover panel from The Shack. Also put a small DVD player in the bin next to the receiver.
