I have this installed in my ford.
It is apparently a japanese radio from the 60's or 70's..
It picks up russian AM channels trough the AM setting in the radio and it works quite well. (yellow light for AM)
But it doesn't play any sound when selecting FM setting in the radio. (Red light for FM)
I'm thinking it might be because in the 60's the FM signal was different than now.
Can i use a FM converter of some type that i just put in between the radio antennae cable?
Such as one of these:
To make it work for modern FM signal?
Do these boxes really work? Or do i have to solder and modify the radio somehow to make it work.
All i want is to be able to play the modern FM radio in mono trough my one speaker in the front.
