... take audio output of my laptop and "broadcast" it to an AM radio* in my own house?

Some mystical box which takes audio in and outputs RF on an AM frequency?

Thanks.

Ah, a fellow antique radio aficionado. Many moons ago, Antique Electronic Supply sold a wireless AM transmitter kit. Worked reasonably well, but it did take a fairly high level of audio output from whatever was driving it to be heard. It looks like they have a different transmitter kit now, but the kicker is the power supply is sold separately. There is also Talking House, which comes up frequently on the antique radio group I'm on.
 
Dave - thanks for the suggestions. I've contacted Antique Elec Supply to ask what they'd suggest; their transmitter kit is no longer available. Remember the days when you could find just about any type of "kit" at Radio Shack, Hallicrafters, Lafayette, etc.?

FYI - here's a Western Television (1929) which after 20 years of searching, I finally managed to find.

Greg - great find. Thanks.

Any idea how to interpret the "1mhz 3mhz 5mhz" detail? Don't know if that would be received by a standard AM radio (550 to 1720 kHz).
Thanks.
Tom M.
Edit: I see the two jumpers for the "three channels" but have no idea how I'd set a kHz transmission rate (550 to 1720) on the device.
 
Hey Tom,
I have no idea, radio is outside my knowledge. Though 1mhz is in the range of 1720 khz. There is a bunch of stuff on Ebay when I searched for AM transmitter. Another thought is to install an MP3 player into your vintage radio. Velleman has a kit for that.
 
Got it. Thanks Greg. My addled brain forgot that 1720 kHz is same as 1.720 mHz. More evidence of brain fade.

At that price, I'll give it a try.
Tom M.
Edit: so setting the xmitter to 1mHz, then tuning the radio to 1000kHz should do the trick.
 
Update: just received that 1-3-5 Mhz adapter. Works perfectly!

I'm using a battery replacer transformer instead of the 3.7v battery required.

Nice to have a way to play laptop audio to the 1930 AK-74. thanks for all the advice.

PS - the old Western mechanical television sits on top of the radio now.
 
Ahhhh... Benny Goodman.
What's the alligator clip on the antenna for?
 
Thanks gents. Leave it to me to try extending the life of ancient tech!

The transmitter's included antenna (18" high telescoping) is wimpy, so I wired it to the hydronic baseboard radiator. Now the whole house is an antenna for the tiny adapter.
 
Greg - easy peasy. I'll just put my 1928 Radiola 18 on the *other* side of the room. Voila - Surround Sound!

1926, WWVA Wheeling West Virginia went on the air out of the broadcasters basement, in 1941 it was granted a 50,000-watt license. A few years later that was my favorite radio station with its old-time country music. Shame it went off the air in 2008, I guess FM pushed them out. I think it's called KXXV now? PJ
 
Hi Paul. I think what folks call "country music" today isn't country music at all. Hollywood and Nashville have taken their toll.

Here's country music to me:


And being a native Texan, here's what I heard while growing up in the 1950s and 60s:


Thanks!
 
Mrs JP and I are big fans of Cosy Mysteries. One favourite is Brokenwood Mysteries out of New Zealand. Mike Shepherd the lead drives a classic car (1971 Holden Kingswood) and is a huge fan of Country Music. (an ongoing part of the plot) I am not a big fan of country music but love the soundtrack of this show almost as much as the show itself. Some very interesting and very unique music. Much more akin to the roots.
