EFR GmbH

HKW-Elektronik GmbH has enjoyed a worldwide reputation for over 25 years. Originally based in the small town of Seebach, she has been continuing her activities at a new place of work in Wutha-Farnroda since November 1, 2015. It is internationally known, especially for processing long-wave information. With the development of specific circuits or, for example, miniaturization in the field of radio clock technology, the founding team Reiner Häcker, Klaus Katzmann and Friedhelm Wieg and their experienced employees have placed HKW on the market as a reliable service developer for clock technology. Despite the German roots, the team not only understands the long wave signal DCF77 of its home country, it is familiar with all systems existing worldwide, whether they are called MSF, WWVB, JJY or, for example, BPC.
