Please, it's JEAN Shepherd.
Spent most of the evenings of my youth listening to him on WOR. Since he was on late, a lot of that listing was done stealthfully “under the covers” with an earpiece I had wired into an old tube radio. He had a nightly radio show for years and did a weekly live show on Saturday nights from a nightclub call the Limelight. He often talked about building radios, DXing and ham radio as well as working in steel mills, his army days in the Signal Corp and reflecting on life and people. He is credited with coining the phrase “night people.”

You could fill a couple of CDs with the great instrumental hits of the 50s and 60s; here are a few more titles:

Midnight In Moscow--Kenny Ball
Apache--Jorgen Ingmann
Apples and Bananas, and Calcutta---Lawrence Welk
Sleepwalk, Teardrop, and Moonlight Serenade---Santo & Johnny
Petite Fleur---Chris Barber's Jazz Band
Lisbon Antigua---Nelson Riddle
The Good, The Bad, and The Ugly theme---Hugo Montenegro
Up A Lazy River---Si Zentner
Only You---Frank Pourcel
Canadian Sunset---Hugo Winterhalter
Mister Lucky theme---Henry Mancini (love that Hammond organ!)

I could go on and on! I'm showing my age now, as I can remember hearing most of this stuff on the radio when they were hits (I'll be 49 this year)

It's finished!
 

Well, I managed to get the AMT3000 transmitter assembled this weekend, and it went extremely well! I started on it late Saturday afternoon, and it took about three hours to get it assembled, and another hour or so to get it setup and tested. I have to say that this is one of the best put-together kits I've ever run across -- an excellent design, very well-made PC board, quality components, and clear instructions.

When selecting a frequency to use, the instructions recommend staying toward the high end of the dial, because the antenna is supposedly more sensitive at the higher frequencies. I was able to find a nice empty slot at 1610, but then I realized that some of my radios won't even tune that high. The next lowest open slot was 1390, so that's what I set the dip switches to.

It was then necessary to fine tune the RF section by hooking up a DC voltmeter, and adjusting a trimmer capacitor for highest reading. (Should repeat this adjustment when antenna is in its final location.) The antenna itself is nothing more than a 118" long piece of insulated wire. The 72" long ground wire only needs to be used in certain situations, since a low RF impedance path to ground is provided thru the AC adaptor and the house wiring.

With the antenna and ground wires just laying randomly on the floor, I connected my iPod digital music player to the inputs, plugged in the AC adaptor, and fired up the iPod. I adjusted the Gain, Modulation, and Compression pots according to the instructions, and then went into the next room to tune in one of my AM radios. To my great joy and amazement, rotating the tuning dial to 1390 brought in the cleanest-sounding signal I could have hoped for! No hum whatsoever, no distortion, excellent strength.

Naturally, my next step was to grab a portable radio and go strolling about the house to check the range and directionality of the signal. There was not a single place in the apartment that the signal was at all affected. So then I went out to my car to see if that radio would pick up the signal. Sure enough. So then I started the car and drove out of the parking lot and down the road. It was still plenty listenable to the end of the parking lot (about 100 feet from the apartment), but gradually started to fade as I drove further away. When I got all the way out to the main highway (about 400 feet away, I could still make out the signal, although very faintly. I was impressed!

What I really like about this transmitter is that I don't seem to have any of the problems that I've had with FM transmitters: low range, random fadeout, extreme sensitivity to antenna position, etc. The AMT3000 doesn't seem to care where the radio is in the apartment, or what position it's in, or if you walk past the radio, or carry it around. It just sounds great! So, If any of you happen to be driving past my apartment complex, be sure to tune in to AM1390, WPMS, and catch about ten seconds or so of my superb programming.

Based on this experience, I can heartily recommend this unit to anyone who wants an exceptional AM transmitter, and who has basic electronic kit-building skills. You won't be disappointed!

Excellent Paula! :thmbsp: Makes me want to build one too!

Congratulations on a winner Paula!
It does look like a fun project. :)

I'm a little suprised the AMT3000 isn't mentioned a little more on this thread than it is?
I'm in the armpit of decent AM, now I can enjoy everything on the web through any of my AM radios with more stations than can be imagined.
If you can melt solder and follow a step by step schematic, you are in like Flynn. www.sstran.com
(just a happy customer)

Although I don't have enough valve BC band radios (yet) to make an AM transmitter, I have for quite a while been transmiiting on VHF FM from an Akai tape deck, an kitset hard drive MP3 player or of late a spare computer. Early versions were simple mono transmitters which had wandering frequency that analogue tuners with AFC could cope with, but now I have a kitset small frequency locked stereo (www.jaycar.co.nz and jaycar.com.au). Requires some delicate soldering of surface mount devices. Runs from a 12v wall-wart. Range about 25yards with a whip antenna and about 100yards when fed up to the TV antenna! Doesn't hum and good quality. Music player is "MP3 Tunes", freeware on the net, does everything, segue, searching and sorting, random play etc. If you're using a really old computer with only DOS then MPXplay by PDSoft, also freeware (I know, I'm cheap!) is good too and also has an 'AGC' function.

There are some fellas supplying some parts for an AM broadcaster....

Nice thread! Really, nice!
I had such an idea for my R&S FM-transmitter, but I don´t dare.
When we married, our music came from a ´56 Grundig console with a Perpetuum Ebner Rex... you can load it with ten 45´s and it is playing them one after another. (By the way, I am made in 69.) Everybody came and asked: What have you done with this thing? It sounds marvelous.
I said: Nothing, but recap.
Strangers in the night, Melody d´amour, Ginny come lately, In the middle of an island, this stuff. Was nice.
And listening to a receiver is another thing than listening just to the amplifier.
Great.
Last saturday we saw "the sons of katy elder" on a ´59 television set. Grin.

ok all you guys now that you have teased me with talk about building a tube am transmitter i would love to see a set of plans or schematic!! i kind of under stand the theroy and am good with tube amp repair but dumb about transmitters -thanks for any help-gary

I own a rhode&schwarz am transmitter built in ´43. Looks like stolen out of u-96. Complete, but not working. A lot of fine mechanics and a hell lot of tubes in this thing.
Would be a good base to build a fine thing.

I have a Rohde & Schwarz EK-07 military shortwave receiver, & it is rather obvious it was made by the same people who made the Tiger tank...It makes an R-390A look like a tinkertoy by comparison...152 lbs of German precision engineering, at a "cost-be-damned" design/build philosophy. The German Army told R&S around 1956 that they wanted the finest radio that it was possible to build, & that's exactly what they got...

Wrong answer, Sandy, grin.
I hoped somebody would say: Really, an am transmitter by R&S, built down in 43, and looking like stolen from u-96?
And there is the possibility for modulate input signals?
Wanna have it!

We should make a new thread discussing fine arts by R&S.
I have no digital cam here at the moment, otherwise I´d show you sth.

Yours
Alex

I can only imagine what a R&S transmitter would be like...Especially for a sub..Harsh environment, difficult operating conditions, had to be run & serviced by a bunch of scared 18, 19, & 20 yr olds who barely knew what they were doing..

It is not made for a sub, it´s just looking like. Grey housing, big round dial in the middle, ancient looking amperemeter at the side and a lot of knobs. Hey, a friend of mine did the pa for Glenn Miller, and he was 19. And a prisoner of war.
Do not forget about the tank-like characteristics of R&S... they even stand emp-shocks...

Have you tried KRLW 1320 from Walnut Ridge? They play some pretty good oldies. (to me anyways :D)
