NDBs typically operate in the frequency range from 190 kHz to 535 kHz (although they are allocated frequencies from 190 to 1750 kHz) and transmit a carrier modulated by either 400 or 1020 Hz. NDBs can also be collocated with a DME in a similar installation for the ILS as the outer marker, only in this case, they function as the inner marker. NDB owners are mostly governmental agen… WebMorse Code Beacon Keyer (C) 2015, G. Forrest Cook Introduction. This circuit stores a morse code message as bits in an EPROM chip, the message controls a relay that keys a CW (morse code) transmitter. An Arduino microcontroller can also be used in place of this circuit, that eliminates the need to build the circuit and program an EPROM.
