@koudimm You can ask the Youtube user (fortyfiveplayer) who sold these boards, but I'm afraid there are no more available at this point.
Your next best bet is the Talking House transmitter--it's the only thing I know of that comes close to the fidelity of this unit. They show up on the secondhand market pretty regularly.
@Fuzy2K It was interestingly different, though I didn't really care for it. There was also a limited edition holiday "spiced" Pepsi product.
I wonder if Pepsi Vanilla is still on the market (or its variants, lemon and lime Pepsi)...I remember having an online conversation years ago where I said that Pepsi Vanilla would be a great idea and then it came out. Even though I'm sure it didn't happen because of my little post, that is The Power Of The Internet(tm).
@V8Jagnut I thought I did well putting it together--but the stereo part didn't quite end up working. Fortyfiveplayer has agreed to take a look at it, so I've sent it back his way. It should be interesting to see what happens!
@bradman5505 I think the Samsung monitor should stay alive for a while yet, since bad caps were the only thing keeping it down. At least I hope it does--it has a nice picture, even though there are some small scars in the top layer of plastic on the display panel.
damn, nice to see an AM-Stereo kit out there.. wonder what the range is on that.. anyway, best of luck, and check out those Atom D525 vids I made.. xD
@Sansui350A With a good antenna, I gather that it is supposed to have a pretty good range, maybe even 'more than it really should'. If you want one, I'd definitely get one, because I think it was said that when these are gone, they are gone.
@coolbluelights AM stereo broadcasting surfaced in the 1980s. What killed it probably depends upon who you ask. I'd say it was a combination of factors--too many standards, many radio buyers not knowing about it or caring, and the already-entrenched FM stereo broadcasting.
I didn't even know about AM stereo until the early 2000s, long after most of the party was over. Even so, a few stations still broadcast this way.
I would not recommend this as a first electronics kit.
@uxwbill haha well I restore tube radios as a hobby, i've been doing electronics since I was 11 or 12 and I've been taking stuff apart since I could use a screwdriver so i'm definitely not a beginner :D this will be a fun project for me^^
@coolbluelights Oh, right! Sorry about that, not sure what I was thinking. I probably WASN'T thinking, something that I'm guilty of more often than I should be! It's much the same thing on this end...I too have been taking stuff apart since I knew which end of a screwdriver to hold. And later, I learned that things could also be put back together (hopefully before anyone got home)! :-)
@THEtechknight The only FM transmitter I have is an Arkon Resources SoundFeeder SF120. It's not bad, but the stereo signal gets noisy quickly as distance from the receiver increases. It also tunes a little bit outside of the proper FM band (85-110MHz on my unit).
Good thing to know there are AM Stereo transmitters available for assembly. I just got my first AM Stereo receiver this week in the form of a Delco radio unit from a 1989 Buick, and it's been ages since I've assembled something by hand, so this is just the ticket!
Reminds me of when I built a AM/FM radio back in electronics school (NEC, which changed to Education America, and probably isn't even in business anymore) way back in 1995.... hard to believe that was over 15 years ago.
Wow, thanks for this Bill, looks to be a lot of fun, gonna order mine right away. I really miss the old Heathkit and Allied Radio, Lafayette, etc. I've built a bunch of them and would love to find the first one I ever built, which was a tube type Lafayette stereo amp back when I was in jr. high school. I search for these every now and then on Ebay.
I got one of these myself and finished mine in about five hours. Very good sounding audio from the finished transmitter even with a receiver with a fussy C-QUAM stage.
Remind me of the older days I used to build cable describers years ago I think it was after I got out of the navy in the late 80s I got a schematic from a electronic magazine had to get the parts from radio shack back when it was a real electronic store but no more today and all the new cable boxes are digital and you cant get free cable anymore . Good luck on the project.
That's neat. Can't wait to see what you accomplish with that kit. I remember listening to AM Stereo as a kid from WOWO when they were still broadcasting music. It sounded great for as far away as I was receiving the signal.
@yamahonkawazuki This is a (so far) low powered radio transmitter that operates on the standard broadcast (AM) band. And, if the receiving tuner can support it, this also produces a stereo signal using the Motorola C-QuAM system. Regular AM receivers will ignore this part of the signal.
Toward the end of its assembly, the power output is supposed to go up. I have yet to watch that video or get that far in the building stage.
@uxwbill What happened to C-QUAM? I remember it being much bigger in the 90s and 80s. I can't find a station that broadcasts on it around central Wisconsin/Milwaukee/Madison.
Far as I know, AM stereo has been around since 1985 - my sister bought a brand new 1986 Pontiac Grand Am with a top-of-the-line sound system that featured the AM stereo mode.
AM stereo is definitely unique, but is, of course, limited by the natural (lack of) frequency response of AM broadcasting.
@SwingMan1937 The FCC approved AM Stereo in 1982, but it took a few years for radios to reach the marketplace. Since 1994, U.S. AM stations have been limited to a maximum frequency response of 10 kHz (versus 15 kHz for FM) in order to reduce adjacent channel interference, but with your own low-power transmitter like this, the audio response will only be limited by the bandwidth of your receiver.
oh pepsi throwback! can't wait till can find it again.

ive got a single-tube AM transmitter, sure it only broadcasts about 20 feet, but hey it works. hehe.
I built an FM transmitter system, which you can find in my youtube videos. not exactly legal, but it was fun...

uxwbill 1 year ago
@uxwbill My best guess it would need a high-Q low-pass filter slapped on its output, and itll suppress the harmonies for anything outside the band.
the BH1415F is a nice IC, thats what i used. it also tunes outside the band a little bit too. .
