Hi again, I read an article on the web that showes how to build a home "AM X-mitter" from an old 5 tube am radio chassis. Has any one tried this out? I would like to know if anyone has made anything simmillar to it and how good it works.Also what kind of antennae would I use.

I want to broadcast some of my old records and tapes to my "radio collection" in my home/shop.
How much wattage is "legal"???

Has any one ever converted an old "CB" or a" SSB " amp for this??

Hope this is the right place to ask about somthing like this,
Thank's for any help or Idea's on this one, Dennis.

Hi Dennis

There are plenty of parts in an old 5 tube radio to build a small trandsmitter but it would take a lot of rewiring. Have you checked circuits on the internet? See address below.

Hi,
Converting a CB, or other amatuer/licensed radio is probably going to be the fastest way to get all of your electronic equipment removed from your house.

In seriousness, do not even consider converting an existing transmitter/transciever. You never know who might be on the listening end, or their temperment. Enforcement is somewhat rare, but there are too many instances where the FCC kicked in doors.

There are a few circuits that are allowed by the FCC for low power AM transmission, and FM transmission too, but they cannot interfere with any licensed stations, plus they are limited to power output of less than about 300milliwatts maximum radiated power.

The link Norm lists is for one that a lot of low power transmitters have been based on. They work well enough for the compressed signals of the 78's.

The circuit you mention initially is one that has a bit more power, and you could extrapolate something that work from the link Norm posted. As long as you selected an area of the spectrum where there are very few stations to intefere with in your area, you should be fine, even if your power should exceed 300milliwats by a little bit.

Thanks John & Norm for the Info. I'll take a look at the link for the one tube X-miter, I dont need to go to jail,just want to get my music up on my old radio's at home. The other x-miter uses a (50C5) for a output to antennae. I might build the one tuber 1st. and see how that goes.

Have you, or Norm ever seen a project for a FM X-miter?

Thanks a lot guy's,for your help, Dennis.

Dennis,

Could you email me or post a link to that site? I'd like to look at the AA5 xmtr.

Hi,
I am not sure what circuit the AA5 will be, but most low power AM broadcast transmitters that use tubes from an AA5 are just using the 6BE6 and 6BA6. In theory, you could set up the 50C5 as the final, and the 35W4 as your rectifier, but that would push the power into the range of interference. For a licensed Ham, it would make a decent low power transmitter; assuming that you are broadcasting outside of the MW band; that would make a novel conversation piece. QRP@5 watts or less.

I was interested having several extra parts AA5's around. I havve buillt the Pop Electronics "Bare Essentials" transmitter using a 50c5 and have been building up a plate modulator for it using the basic circuit from the Heath Twoer. Just wanted to see how someone had made this tube into a low power xmtr for the BC band.

Hi Dennis,
I converted an AA5 to an AM xmitter a few years back, based on a post to rec.antiques.radio+phono by George Gonzalez. Basically you series both sections of the tuning capacitor and connect to the osc to bring it down to the right range, then use the output tube to plate modulate the osc. About 5 steps and a few wires,a cap and a audio xfmr to couple audio to the xmitter (I used a 70v line xfmr off of a paging speaker). Be extra cautious if you try this, you could damage your music source or yourself.

Mine worked pretty well, had a small amount of hum that I couldn't get rid of (normal for AA5). Modulation could be better, but the cost was small. I was always nevrous using it, used an isolation xfmr with it. I have a Vetronics AM xmitter that I prefer much better.

Good luck & be careful of the AA5's, Robert
