James Douglas Radio Question

[eric wissing]

James, in another post it was mentioned that you have a satelite radio in your car. How briefly, did you get that to work? The Sirius Radio That I have transmits an FM signal. Did you convert one to transmit AM? And are you running 12 volts? Thanks, Eric

My 6 volt 53 Cranbrook has one of those FM converters that has been adapted to operate on 6 volts. MyXM radio actually operates on a reduced 12 volts down to 6 volts so a cigar lighter with no voltage drop works well. I just dial the AM radio to the converters frequancy then the converter to the XM frequancy and turn on the XM radio. Works well. I did the same on my 63 Belair without the reduction in voltage.

Eric,

I have a prototype for a AM Transmitter. You use an antenna "Y" and plug it in. What ever you play into the transmitter is picked up by the radio. You can still use the radio just like normal.

I can use an iPad, Xm radio, or anything else with an line level output.

I don't know what Bob Amos is talking about as the FM transmitters that you can get with the XM radio's is FM and our radios are AM. Bob, can you elaborate a little ?

I have two units I am building now for a couple of friends. In small quantities of one and two they are rather expensive (around $200) but the folks I am making them for a re driving 1930's Cadillac's and Packards so they can afford it.

Best, James

James it sounds a bit like the AM transmiters that people use to broadcast to their home radios. Many collectors of old radios like to control the music that is comong out of their 24 tube 3 ton Scott radio. Thanks, Eric

Eric,

It is based on that type of unit. It has to be modified to work on 6 Volt Positive Ground however.

The ones I use can work on 6 to 12 volts and either ground. It is also calibrated as a direct feed, so as to not overload the radio.
