Fax receiver for VLF and SW

A receiver circuit is described which, in its basic contiguration, opens up the trequency range below the range allocated to long-wave broadcast services. This so-called VLF (very low frequency) range is particularly interesting to the radio amateur because it is used by weatherfax and other utility stations. Several stations can be received which transmit weather charts, satellite images tor sea and air navigation, and miscellaneous meteorological data. The receiver is simple to modity for shortwave reception on 80, 40 or 20 metres.
