OPERATION
FREQUENCY AND CHANNEL SELECTION
The VX-1700 includes the following frequency selection
capabilities:
 A VFO (Variable Frequency Oscillator) System
 ITU Marine Channel
 Memory Channel
 A one-touch (2.182 MHz) Emergency Channel
Memory, which places the transceiver on 2.182
MHz (in transceivers configured for Marine use).
 In the VFO mode, the frequency is displayed on the
right side, with the operating mode icon being displayed
at the left edge of the display. On the left side of the
display, the current synthesizer step size is displayed.
 In the ITU mode, the frequency and operating mode
are displayed as they are during VFO operation; how-
ever, the left side of the display indicates the ITU Ma-
rine Channel designator.
 In the Memory Channel Mode, the memory channel
number is displayed on the left side of the display (for
example, 1-005). The digit to the left of the hyhen is
the Memory Bank Number, while the digits to the right
are the Channel Numbers within that bank. Therefore,
in the example below, the display is indicating Chan-
nel #5 on Memory Bank #1.
 In the Emergency Mode, the frequency “2.182.0” is
displayed on the right side, with the special Alpha Tag
“EMRG.”
Frequency and channel selection are very simple on the
VX-1700:
Select the desired channel grouping (VFO, ITU, and
Memory Channel) by repeatedly pressing the keypad’s
[

)]
key. The circulation of channel groups is VFO

 Rotate the CH Selector knob to select the operating
frequency.
 If the tuning rate is too slow or too fast, the frequency
synthesizer steps may be changed by pressing the
keypad’s
[

(
STEP
)]
key. Available step sizes are 10
Hz, 100 Hz, and 1 kHz.
 The microphone’s
[
UP
]
or
[
DWN
]
button may also be
used to select the operating frequency. Pressing the UP
or DWN button momentarily will cause the operating
frequency to increment or decrement one step, respec-
tively. Pressing and holding the
[
UP
]
or
[
DWN
]
but-
ton in for 1/2 second will initiate upward or downward
scanning, respectively. Releasing the
[
UP
]
or
[
DWN
]
button halts the scan.
 The VFO frequency may be entered directly from the
keypad.
 Press the keypad’s
[
ENT
]
key momentarily, then
enter six digits of the desired operating frequency
(the “10s of Hz” digit can not be entered, even if
10 Hz steps are selected; this is a time saving fea-
ture). If you make a mistake during frequency en-
try, rotate the Channel Selector knob so as to cause
the erroneous digit of the frequency to blink; now,
press the correct number on the key pad, and con-
tinue with the remainder of the frequency entry pro-
cess.
 If you require split-frequency operation (different
transmit/receive frequencies), press the
[
ENT
]
key
momentarily, then enter the six digits of the desired
transmit frequency; otherwise (to transmit and re-
ceive on the same frequency), skip to the next step.
 Press and hold in the
[
ENT
]
key for 1/2 second to
finalize the entry of the VFO frequency (frequen-
cies).
 If you need to change the operating mode, press the
keypad’s
[

(
MODE
)]
key. Available operating modes
are J3E(USB), J3E(LSB), J2B (USB), A1A(CW), and
A3E(AM).
