You can look in the Homebrew section of ARF for several different schematics of transmitters that are relatively simple to build. Most of them use a crystal controlled oscillator, so what frequency you are going to transmit on depends upon being able to purchase that oscillator component for the specific frequency you need, which is often not possible to obtain. However you could build one of the transmitters that has a tunable output frequency.

You could also buy a ready made unit from Talking House which has an ad on the right side of the page-------->

Most people have had the best luck with transmitters that operate near the high end of the AM band around 1600 or so.


Experience is what you gain when the results aren't what you were expecting.

+1 Dennis,

I exclusively stream off my computer/Internet. I like to listen to an oldies Internet station out of Connecticut. I have a small transmitter that I use which might work for you too. PM me and I'll send you a small PDF document that has the print and all the other information about it. Parts are cheap and simple, you should be able to get them all in your area.
