[sci.electronics] Need FM Transmitter Ideas

stever@wjvax.UUCP (Steve Reinhold) (03/14/89)

I need to buy or build a low power FM transmitter which will work on the 
standard 88-108 MHz FM band. I remember seeing wireless microphones that do
this, and while in Japan I actually saw a watch with a 78 MHz transmitter built
in. 

The unit must transmit a signal with sufficient power to be received on a
standard FM radio with a range of about 100 feet. The signal source will be
standard audio from a tape recorder.

Has anyone seen such a device? If not, any ideas where I can find a circuit?
What is the FCC limit on output power of such devices?

Please reply by email as I'm not a regular reader of these groups.

Thanks in advance.

There is a article in the March issue of Radio-Electronics that is just
what you need.
