QK7: 3V FM Transmitter Kit
VIEW LARGER IMAGE
Yes, It's In Stock! This is a KIT and requires assembly!
The most powerful bug for it's size. Uses trimcap for easy tuning in the FM band. 50 meters within buildings, 300meters or more in open. Full documentation and battery holder included, 3vDC.

Price: USD $12.95

Special: 100+ items at $10.75 each, 50-99 items at $11.01 each, 10-49 items at $11.66 each

Quantity: QK7: 3V FM Transmitter Kit
The Comrade FM transmitter (FM Tx) is about the simplest and most basic FM Tx it is possible to build and have a useful transmitting range. It is surprisingly powerful despite its small component count and 3V operating voltage. It will easily penetrate over three floors of an apartment building and go over 300 meters in the open air.

It is superior to many other similar FM Tx kits available. We have examined a total of six kits and found them all to have higher component counts, higher current drain yet a poorer performance than this one. One kit we bought simply did not work at all. A second had an incorrect transistor on the output stage; when replaced with a proper RF transistor its performance improved immediately.

The circuit we use is based on a proven Australian design. It may be tuned anywhere in the FM band. Or it may be tuned outside the commercial FM band for greater privacy. (Of course this means you must modify your FM radio to be able to receive the transmission or have a broad-band FM receiver.)

NOTE: The output power of this FM Tx is below the legal limits of many countries (eg, USA and Australia). However, some countries may ban ALL wireless transmissions without a license. It is the responsibility of the purchaser to check the legal requirements for the operation of this kit and to obey them.

The kit is constructed on a single-sided printed circuit board (PCB).

Dimensions: 46 x 19mm
