After the desired analog mode has been set, access the IF
bandwidth menu as follows:
1.
Long press [MODE] and use [ ▶ ] to select [IFBW],
followed by [ENT].
2.
Use the arrows [◀] or [▶] to select the desired bandwidth
and validate with [ENT].
(Greyed out values cannot be selected.)
User selectable bandwidths for each of the analog modes:
FM
6, 15, 30,100 kHz
AM
3.8, 5.5, 8, 15 kHz
USB
1.8, 2.6 kHz
LSB
1.8, 2.6 kHz
CW

SQUELCH
Squelch is a function which quiets the background "white" radio noise, when no signal is
present. It operates in analog modes (FM, AM, USB, LSB, CW) and the digital auto-mode
(AUT1). It has no effect for the individual digital modes (DSTR, YAES, DMR, D-CR(NXDN),
dPMR, ALIN, P-25, T-DM) as the receiver only lets audio pass through when a digital signal
is detected.
The squelch can be manually "opened" to allows signals to be heard, or "closed" to mute the
audio of the signal.
When the squelch is "open", the indicator
When doing a memory SCAN or SEARCH, the squelch setting is very important as it serves
as a threshold to the receiver to determine if there is indeed a signal or not, and when to
resume scanning.
Squelch type and threshold value example
(for busy) appears on the left side of the LCD.
