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.
