We are a local chapter of DARC, the nationwide ham radio society in Germany. Our location is the North Western Black Forest. The Black Forest is a mountain range in the South West corner of Germany. Our members identify on air using DOK A5Ø. DOK identifies all local chapters of DARC as a letter followed by 2 digits. Letter 'A' denotes the Baden district. Award hunters collect DOKs for the popular DLD award (Germany award). A5Ø is relatively hard to work because of the moderate number of members (hardly two dozens). Contact us if you wish to set up a sked.

Most of our members are living within the Central/North Black Forest Nature Park. A natural highlight is the Kaltenbronn Reserve hosting Lake Wildsee and Lake Holoh (about 900m above sea level). It is an almost untouched wilderness, yet it is accessible to tourists. They stay on prescribed paths, preventing visitors from sinking into the bog. Lake Wildsee is the biggest raised bog pool of Germany.
Visits are recommended over the summer months since the temperatures in this area are substantially lower than in the valleys. Kaltenbronn Reserve is also the temporary QTH of one of the world's leading VHF contest stations, namely DR9A operated by a neighboring DARC chapter.

The formal home of the Murg Valley club is Mount Teufelsmühle(48°45.42'N 8°24.47'E, JN48es81) which is also hosting our UHF relay DBØTFM, APRS stations, and an Echolink relay. Likewise, it is the home location of our club station DLØMUR. As the facility is administered by the Black Forest Club (a non-radio org) we decided to keep the station profile low and to install our HF antennas only when needed. This keeps the visible impact low. Only the small relay and digipeater antennas are installed permanently on the tower roof.
