1993 buick lesabre radio weirdness
 
When i have the balance in the middle, only comes out of the left side and when the balance is turned to extreme right and volume turned up some, sound comes out of both sides equally but the right side crackles and hisses while the volume is down.

Never seen that. Maybe the pot for balance is just dirty/broken. Those old radios aren't particularly hard to disassemble, but you may have to just desolder the pot and actually open it to inspect/clean it.

Also... I don't know if any of those Buicks ever had an optional amplifier, but be certain it doesn't have one, as that may be your problem area.

I did have a similar GM radio in a chevy van once that only received a morse code signal, for the letters KM over and over again.

Where were you located at the time? The only navigation aids that use "KM" code as an identifier are not in the US. :scratch2:

That might be the case.

Chicago, lol? Why would navigation aids be using morse code identifiers broadcast as sound beeps in analog radio? :scratch2:

For easy identification... The 2 and 3 letter code id is related to the airport name...

It is possible that these low frequency signals might be picked up by the if amp in AM radios, particularly auto radios that often have an if frequency in the 200 to 300 khz range instead of the more common 455 khz.

Note: 262.5 khz is apparently common auto radio if

Just hit the auto salvage yards and save yourself the trouble.
If you remove it yourself, you can get if for $20 or less.

I mean maybe, but it was only two letters, over and over. Pretty hard to screw up.
