WisyCom CST38 VHF Transmitter Module

Untested and sold as-is.

Item description from manufacturer:

General Description The CST 38 transmitter has been especially designed to allow best usage of MicroEar’s family “in-ear receivers”, and many modulation parameters such as deviation, level/frequency curve, compression factor has been optimized. Therefore CST 38 assures maximum performances of MicroEar both as sound quality and as audio level (in any case limited because of the very small size of receiver). Higher power transmitter are available to further increase the coverage area (cell); it is also possible to link in parallel several transmitters (in iso-frequency mode) to create a multiple cells coverage. MicroEar internal battery has about 30 hours working autonomy; in any case the original battery once activated (taking out metal label) has a limited life even in power off. When empty battery, MicroEar will drastically reduce audio level and receiver sensitivity.
