The BST-25/216 Synthesized Base Station Transmitter from Comtek is an auxiliary base station transmitter designed to operate in the newly assigned 216-217MHz band under part 95 of the FCC regulations. For highest fidelity operation, the PR-216 receiver must be used with the wide-band companded channels.

The BST-25/216 transmitter incorporates the latest digital and analog technologies to produce low residual noise, wide dynamic range, and extended frequency response rendering the most natural sound possible from a wireless system.
