6 REJECTING INTERFERENCE CHANGING THE CUTOFF FREQUENCIES (LOW AND HIGH FREQUENCY) TO ADJUST THE PASSBAND WIDTH CHARACTERISTICS In the SSB, AM, or FM mode, you can modify the passband width of the filter by changing the cutoff frequencies (low and high frequency). You can change the passband width so that interference will be outside the bandwidth of the filter. Low Cutoff Frequency Range High Cutoff Frequency Range Interfering Signal Target Signal Interfering Signal 0 Hz 600 Hz 2 KHz 5 KHz 4 Press [ESC] to exit. Pressing [FIL/SEL] (M) or [FIL/SEL] (S) closes the RX Filter screen. Note: ◆◆You can view the progress of adjustments while the sub-scope appears on the sub-screen. Mode Low Cutoff Frequency (Hz) Setting Value SSB/ 0/ 50/ 100/ 200 (default) to SSB-DATA 2000 (100-step) High Cutoff Frequency (Hz) Setting Value 600 to 2800 (default) to 3000 (100-step)/ 3400/ 4000/ 5000 AM/ AM-DATA 0/ 100 (default)/ 200/ 300 2000 to 3000 (100-step)/ 3500/ 4000/ 5000 (default) FM/ FM-DATA 0/ 50/ 100/ 200 (default) to 1000 (100-step) 1000 to 2800 (default) to 3000 (100-step)/ 3400/ 4000/ 5000 .

CHANGING THE CUTOFF FREQUENCIES (LOW

AND HIGH FREQUENCY) TO ADJUST THE

PASSBAND WIDTH CHARACTERISTICS

In the SSB, AM, or FM mode, you can modify the

passband width of the filter by changing the cutoff

frequencies (low and high frequency).

You can change the passband width so that interference will

be outside the bandwidth of the filter.
