Mr Kogawa’s Micro FM Transmitter is a short range FM radio transmission kit, it can be tuned to broadcast on any part of the FM range and is amazingly clean and stable. A connection for an optional external antenna means that you can boost the range if you wish to do so. The original design of this transmitter circuit was created by Mr Tetsuo Kogawa, he is an artist, teacher and all round guru of Micro FM.
