OK, just to clarify again.

The first stereo was an aftermarket one, I replaced it with the factory one from this car(8. Then I tried the one from my other car(87). After 3 radios doing the same thing, I tried hooking up the original antennae with a new antennae wire. Now today I put the 87 radio(the one I've been using lately) back into my other car(the 87), and it didn't work.

The aftermarket stereo has the same symptoms and is an older pull out unit, the two factory ones are like the one here.

It does work intermittently, it just jumps around to different frequencies.

thanks again for the help guys, it'* impossible to find anyone that will say anything other then buy a new aftermarket stereo.[/url]

Its hard to say what the issues will be with those stereos... They were full of issues... I went through 3 of them in my 91 Bonneville LE... The one in the pic should not have the CDM box, but it should have the amp on the left side of the unit... Sometimes the right front channel will burn out and either get flat or very static like... Other times I have heard of the tuner going out and getting funky... I have never had the funky tuner issue with one of those units tho.. Usually burnt out channel or 2... About 4 or 5 years ago I started using these units from the Loaded SE Bonnevilles or SSE Bonneville.. But they have a delco loc function( PITA to get around )

Here is the unit I switched to..

I wouldn't mind getting a newer unit for my daily driver, but it would have to be all black with red/orange lights like my factory one. The problem is that I'm not sure that'* such a good idea since I've lost three radios in a row in the same car in a short time period. I'd like to narrow down the cause first.

Just an off the wall question... What voltage is your alt putting out?

And by chance what voltage do you get at the 12v constant and 12v switched wires?

~12 volts with engine off, ~14.5 with engine running. The car'* voltmeter is always dead steady.

check with a external Volt meter at the battery. dont rely on the the dash volt gauge.

I've tested right at the radio, it'* good. While the car'* voltmeter may be a little off, it'* still good for checking for peaks and drops.

The tank circuit in the FM tuner block has probably gone bad. Wandering stations, while not very common with digital tuners, can still happen when the capacitors and resistors (more commonly now part of an IC, but may by individual surface mounted components in an older unit such as yours) used to select the IF frequency fail, in your case they are likely going into thermal run away.

Time for a new radio.

Thanks for the information. However, I've already replaced the radio twice. Aren't I risking destroying yet another radio? I need the source of the problem.

Ultimately your radio needs to be repaired or replaced. Unless you somehow had voltage back feeding through the coax I don't see how its possible. Go to your local stereo shop and grab an antenna extension of reasonable length and substitute that instead of the antenna lead that is already in the car. Purchase an a stereo that offers a return policy so if by chance it does become damaged you can easily return it for a refund.
