Dual-Concentric Potentiometers
AF — SUB AF gain controls for main
receiver (inner, or smaller knob) and sub receiver
(outer ring, or larger knob).
RF / S Q L — SUB RF gain (and/or squelch)
controls for main and sub receiver.
Two menu entries are provided to control squelch
directly: CONFIG:SQ MAIN, and SQ SUB. They
can also be used to reconfigure the RF gain controls
as squelch for either receiver, and to select FM-only
or all-mode squelch. See Config Menu (pg. 53).
Multi-Function Controls
The upper two multi-function controls set up
receiver filtering. The lower two controls adjust
transmit settings. Each control has two primary
functions (white labels) and a secondary function
(yellow). Tap a control knob to alternate between
its primary functions, indicated by two LEDs. Hold
a knob (~1/2 second or longer) to select its
secondary function.
Filter Controls
The primary functions of the filter controls are:
S H I F T Shift passband either direction
L O C U T Adjust low-frequency response
H I C UT Adjust high-frequency response
WIDT H Adjust width of the passband
As these settings change, so does the filter graphic.
Crystal filters are selected automatically (or
manually using XF IL , pg. 15). Also see Filter
Passband Controls (pg. 23).
The secondary functions of these controls are:
NO R M Normalize passband
Normalizing the passband sets the bandwidth to a
fixed, per-mode value (e.g. 400 Hz in CW mode)
and centers the passband. (Also see user-defined
normal settings, NOR M1 /2, pg. 24.)
I/ I I Select preset I or II (per mode)
Presets I and II each hold a continuously-updated
DSP/crystal filter setup (pg. 24).
Transmit Controls
The primary functions of the transmit controls are:
S P E E D Keyer speed in WPM, 8-50 (8-100
if CONFIG:CW QRQ is ON)
M IC Mic gain
C M P Speech compression level
P W R RF output power in watts (pg. 26)
The present transmit mode determines which
primary functions normally apply; for example, in
CW mode, the SP E E D / M IC control defaults to
SP E E D . You can always tap a knob to override
the present selection.
The secondary functions of these controls are:
DEL A Y VOX delay (voice/data) or CW semi-
break-in delay, in seconds
MON Voice or data monitor level or
CW/data sidetone level
You can optionally LOCK the MIC, CMP, and
PWR control settings; see CONFIG:PWR SET.
VFO Tuning Controls
VFO A controls the upper frequency display. This
is normally the RX and TX frequency. In SPLIT
mode, VFO B controls the transmit frequency (pg.
36). VFO B also controls the sub receiver (pg. 37).
The controls to the right of VFO A include:
FR E Q EN T Direct frequency entry (pg. 15)
SC A N Start or stop scanning (pg. 40)
F INE Select 1 Hz tuning for both VFOs
and RIT/XIT offset
CO A R S E Select coarse tuning rate (pg. 22)
RA T E Select one of two normal tuning rates
(10/50 or 10/20 Hz; pg. 22)
L O C K Lock VFO A (use B S E T to lock B)
SU B Tap to turn sub RX on/off (pg. 37).
Hold to link/unlink VFO A and B on
the present band (pg. 37). A long hold
(2 seconds or longer) enters diversity
mode (pg. 38).
VFO A can optionally be coarse-tuned using
the RIT/XIT offset control if both RIT and XIT are
off . See CONFIG:VFO OFS.
