Kalundborg 10 MHz frequency reference
Ever since the long-wave broadcast station Kalundborg changed its frequency from 245 kHz to 243 kHz to comply with the CCIR's recommendations for a 9 kHz raster in the LW and MW bands, it has become possible to use the carrier tn the locked frequency standard described here. Kalundborg is a 300 kW long-wave transmitter in Denmark, with a range of about 500 km (300 miles). This article is, therefore, of particular interest to our Scandinavian readers.
