Over the past two years I've built & experimented with numerous low powered FM transmitter (as well as a couple of mediumwave & shortwave circuits, but that's not going to be the focus of this page... maybe some time later). What I'd like to do is tell you about some of the exciters I've built & describe the various strong points and weak points of each. Pirating is a fascinating & addictive (but ultimately illegal) hobby. If anybody out there is thinking of starting up their own station, take a look; I hope that my recommendations will be of some help to you.
Each of these units was built from a kit. All of these can be purchased completely assembled and test, though that usually increases the cost significantly. But... even if you DO know what your doing, this is often the best way to go since the people who will do the assembling for you are often the ones who designed the circuit in the first place. This reason alone makes the extra few buck a worthwile investment So, if your not too handy with a soldering iron, leave the kit-building process to the pros (especially with the PLL devices; they can be a PAIN IN THE ASS even if you know what your doing. Believe me... I know what I'm doing & at first I wished I'd NEVER EVEN ATTEMPTED the Broadcast Warehous circuit! It came out alright after a while, but I did eventually have to send it back to England for a tune up. Also, all transmitters here are monophonic. Click on the links below for more information.

This transmitter is built around Veronica FM's 50 mw mono transmitter board. For those of you who don't know your milliwatts, that's 1/20th of a watt of output power. I originally built this circuit to re-broadcast CDs and other audio sources throughout my house, but after some experimentation I found that if it's hooked to a good antenna using good low-loss coaxial cable, a loud, clear signal is possible at distances of more that a mile. The example you see here is built into an ordinary water-proof single-gang junction box (availible at any hardware store for less that four bucks). Add to that the fact that the transmitter circuit itself can be had for around $25USD & you can easily see that it's possible to put together an honest to goodness, local FM broadcast station for well under $100USD (that includes the feedline as well as the materials to build the antenna). |
