Transmission site Landespolizeidirektion Karlsruhe, Police telecommunications facility on Lerchenberg hill, Wildberg, Germany

The transmission site on Lerchenberg hill near Wildberg is a police telecommunications facility with an 81-meter tower equipped with shortwave aerials. It provides radio coverage across much of Baden-Württemberg to support regional emergency services and law enforcement communications.

The facility was built to secure emergency communications for police, fire services, and disaster response in the region. It developed as part of Germany's distributed infrastructure for coordinating response forces across Baden-Württemberg.

The site is run by the Interior Ministry of Baden-Württemberg, and its radio networks coordinate police, fire service and civil protection units across the whole state. The name Lerchenberg comes from the hill above Gültlingen, a district of Wildberg in the Calw district. Until 1992 the grounds also served civil defence, which is why several underground bunkers remain.

The site sits on the Lerchenberg hill northeast of the Gültlingen district of Wildberg, about 20 kilometres west of Stuttgart. An access ramp leads down to the underground premises, and the grounds are fenced off as an operating police facility. There is no visitor access; the 81-metre concrete tower and aerials can only be seen from outside the perimeter.

The site lies on the Lerchenberg northeast of Wildberg's Gültlingen district, not in the Black Forest. Its 81-metre concrete tower carries 70-cm directional antennas and numerous 4-metre antennas, and several dipole antennas serve shortwave. Underground bunkers remain from civil defence use until 1992.
