pa When you say "keeping it to one station"... do you mean the AM or the
pa FM?... I want to be able to change the AM, but if I have to keep the
pa Blaupunkt at one frequency to receive the signal from the converter, I
pa wouldn't mind at all.


There used to be all transistor converters like that back when. Now
that I think of it there might even be one in the garage here. I'm not
sure though, but the last time I was clearing room for the car I
vaguely recall coming across such an FM converter on a shelf. Would it
be something you might want if it works?

A*s*i*m*o*v

.... I can't remember the last time I forgot something.

GS Seeing as how you are a "packer fan" I may have just what you are
GS looking for. I have one of those FM to AM converters. Got it sometime
GS in the 70's. It is a very small box about 3/4 inch high by about 4 x 6
GS inches. Used it in a car that came with only an AM radio. Just plugs
GS into the antenna jack and the car antenna plugs into it. Needs to also
GS hook to 12 volt power. Push the button and it switches the converter
GS in line. Set a push button on the am radio the the output frequency of
GS the converter and tune in your FM station with the knob on the
GS converter. It is mono FM though. No stereo. Works great. Email me at
GS if interested.


I found the converter box in the garage shelf I had mentioned. However
it turned out to be an 8-track converter. Remember 8-track?! WOW!

A*s*i*m*o*v

.... I cut it three times already and it's still too short!

Hello, I have a 1969 Porsche that has an original, Blaupunkt, radio.
The AM works, but the FM does not. I was trying to find information on
a "FM to AM converter". If anyone has a schematic, or any advice at
all, I would GREATLY appreciate it. Thanks in advance!




I'd call these guys up (http://www.radiomanrepair.com/) and see if
they'll provide a quote for repair of the OEM radio. You'll have a
neat, operating vintage car radio, and you might even get the cash
back when you sell the car.

It isn't trivial to convert FM broadcast signals for reception in the
AM band. You pretty much need a back-to-back FM receiver and an AM
transmitter to do that, and the RF work associated with homebrewing a
converter would (honestly) place the task out of reach for anyone who
needs to ask how to do it. :-)

They used to sell FM to AM converters for car radios. They 'worked' ok.
Watch ebay for Audiovox FM Converter. Here's one example.

Hey if you are interested I have the EXACT same unit that the above link
points to (except mine was OEM'ed by Lafayette radio and has their name
on it). Is it worth anything near what the audiovox unit sold for?
