3.3.8 BEAT FREQUENCY OSCILLATOR OPERATION
The Beat Frequency Oscillator feature is available for selection when the
receiver detection mode is set for CW operation. This feature injects an
offset frequency into the signal path so that unmodulated signals produce
an audible output. The BFO feature permits adjustment of the offset
frequency by
±
8.000 kHz, adjustable in 10 Hz increments, to alter the pitch
of the audio output. When the CW detection mode is selected, the BFO
feature is activated by pressing the BFO key. When active the LED on the
key lights, and one of the digits in the BFO field of the display flashes.
Each press of the BFO key moves the flashing digit to the next digit,
determining the resolution of the EDIT knob. Selection of the BFO
frequency may be performed by direct keypad entry (in kHz), terminated
by the BFO key, or by rotation of the EDIT knob.
The secondary function of the BFO key (when the SHIFT LED is lit) is the
+/-ZERO function. It determines the frequency sense of the frequency
offset. Each press of the key switches the BFO between a positive offset
value, a negative offset value, or zero offset (+0000).
3.4 MEMORY PROGRAMMING
The WJ-8611 Receiver contains a 200-channel programmable memory for
storage and retrieval of receiver parameters, and a 200-channel lockout
memory for storage of lockout frequencies associated with F1-F2
frequency scans. Each of these memory sections is programmed with the
receiver parameters used for the receiver’s Channel and F1-F2 scan
operations. Before a scan operation is initiated, the appropriate memory
must be programmed with the parameter data that is to be used in the
operation. The paragraphs that follow describe the memory programming
operations and the memory applications.
