Radio or Speaker problem? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

67CHIP72 · 04-13-2008, 05:55 AM

When I turn the original AM radio on in the truck at full blast on a quiet night I can just barely hear it. Do you think the radio has a problem or the speaker has gone bad?

P.S. I have good hearing

id wager on a blown speaker, if the radio is still pushing sound even to the smallest extent its probly not bad unless u broke some stuff in the radio dukes of hazzarding ur truck reaently

The antenna can cause low volume also. If you have a known good antenna, try plugging it in before pulling the radio.

Has it ever worked? Here's what I did would do.

First check it with another speaker and if volume is still low, take the radio out and give the volume knob variable resistor a good cleaning with elecro clean.

One last thing is to make sure the antenna has a good clean connection and adjust the pod under the tuner knob for maximum reception...

in my assembly instruction book it give a procedure for peaking the antenna trimmer
1. set antenna mast at a height of 31+/- 1.0 inches
2. set volume control knob at max volume
3.tume radio to a signal at or near 1400 kc
4. adjust antenna trimmer screw(+/-2 screw rotation) until maximum volume is received
5. turn receiver off
try this I hope this will help

By process of elimination, bad speaker and antenna. Now that I have it all working, it's ime to put it back together. Thanks for the help everyone.

67CHIP72, good to hear you found your problem... Now, when you get it all fixed you can help me out. See if you have an AM station beyond 1510 or higher in your area and see if you can get it. I can't seem to get a 1620 station that we have in our area....

Check in here to see if you do...

It's possible your dial is not turning all the way to where it should. Now that you asked me this, I tried mine and it only turns right to just past the 14, yet that is a vietnamese station too. I tried listening to it for a station identification, but all I understood was "Disneyland". Another non functioning radio I have turns past the 16, but I have no way of checking the stations.

You have these staions that may be available depending on your reception.

KMPC 1540 AM 32.6 mi. Los Angeles, CA Asian
KBLA 1580 AM 35.2 mi. Santa Monica, CA Spanish
KAHZ 1600 AM 27.4 mi. Pomona, CA Asian
KFOX 1650 AM 34.9 mi. Torrance, CA Asian

If you can't get any of these, even faintly, I think that tells me that it's our old radios. Maybe they can't go beyond the low 1500's.

Thanks.
