PANEL DESCRIPTION 1 IF NOTCH CONTROL NOTCH outer control p 28 Adjusts the center frequency of the IF notch filtering frequency while the IF notch function is ON The auto notch function DSP equipped type only can be used together with the IF notch function Simplified example of the notch function APF NOTCH APF NOTCH APF NOTCH Turns the auto notch function ON and OFF in SSB mode The red indicator lights when the function is ON SELECT SWITCH SEL p 54 In the memory mode designates or cancels the MAIN readout memory channel as a select memory channel for select memory scan when pushed momentarily appears when the MAIN readout channel is a select memory channel Cancels all select memory channels when pushed for 2 sec ELECT disappears from all select memory chan nels Toggles between memory scan and select memory scan during memory scan FUNCTION The notch function eliminates unwanted CW or AM carrier tones while preserving the desired signal s audio response The filtering frequency must be adjusted to effectively eliminate an unwanted tone for the IF notch or turn the auto notch function ON 2 kinds of notch functions IF DSP are adopted in the DSP equipped type AUDIO PEAK FILTER SWITCH APF p 30 Turns the audio peak filter ON and OFF The red indicator lights when the function is ON Use the APF control to vary the peak frequency IF NOTCH SWITCH NOTCH p 28 Turns the IF notch function ON and OFF The red indicator lights when the function is ON The auto notch function DSP equipped type only can be used together with the IF notch function Use the NOTCH control to vary the filtering fre quency AF LOW PASS FILTER SWITCH AF LPF For Non DSP type Turns the 1 5 kHz cut off audio low pass filter ON and OFF AUTO APF NOTCH SWITCH AUTO p 30 For DSP equipped type Turns the auto audio peak filter ON and OFF in CW mode The peak frequency equals the CW pitch frequency set in P set mode or by the SQL control p 43 Turn the PSN demodulation ON using P set mode in advance p 42 The red indicator lights when the function is ON The audio peak filter can be used together with the auto audio peak filter to boost up the attenuation MEMORY CLEAR SWITCH CLEAR p 49 Clears MAIN readout memory channel contents when pushed for 2 sec in the memory mode The channel becomes a blank channel and BLANK appears This switch does not function in the VFO mode MEMORY WRITE SWITCH MW pgs 50 52 Stores the MAIN readout frequency and operating mode into the MAIN readout memory channel when pushed for 2 sec This switch functions both in the VFO mode and memory mode Memory write and clear can be performed to the MAIN readout only MAIN SUB CHANGE SWITCH CHANGE pgs 33 35 Toggles the frequency and selected memory channel between MAIN and SUB readouts Toggles between transmit frequency and receive frequency when the split frequency function is ON VFO EQUALIZATION SWITCH EQUAL p 33 Equalizes the SUB readout frequency to the MAIN readout frequency when pushed for 2 sec Equalizes the receive frequency to the transmit frequency when pushed together with XFC for 2 sec while the split frequency function ON MEMORY TRANSFER SWITCH M V p 51 Transfers the frequency and operating mode in a memory channel to MAIN readout VFO when pushed for 2 sec This switch functions both in the VFO mode and memory mode 8
