Crystal controlled stethoscope audio transmitter

Ideal for audio monitoring through window glass, wall and even ceiling, this contraption is highly sensitive due to the presence of piezoceramic converter based sensors. As a lithium 3V cell CR2450 powers a built in power supply mechanism in a tiny cylindrical case, it can easily be mounted on window glasses due to its minute size and special design.

Remote control via radio frequency is made possible because of its flexible external antenna. To make the most out of this device and to get the best quality of sound, use it in conjunction with our specially designed WFM scanning receiver IC-ERRE.
