Keyboard Frequency Entry
You may enter operating frequencies, for either the Main
(VFO-A) or Sub (VFO-B) bands, using the front panel
band/frequency selection keys.
Example 1:
Enter 14.250.00 MHz into the Main band (VFO-A):
1. Press the [
ENT
] button
to engage the direct fre-
quency entry process.
Now, beginning with
the “10 MHz” digit of
the frequency (the
leftmost digit), we will
enter the required dig-
its of the frequency.
2. Press, in order, the digits of the operating frequency,
using the [ BAND
] buttons (which have the frequency-
entry digit or decimal point on the right side of the
slash bar). In this example, enter
[
1.8/1
]
Æ [ 10/4
]
Æ
[

Æ [ 3.5/2

Æ
[

Æ [ 50/0

Æ [ 50/0

Æ [ 50/0
]
Æ [ 50/0
]
The decimal point after the “MHz” portion of the fre-
quency must be entered, but no decimal point is re-
quired after the “kHz” portion.
3. Press the [
ENT
] button once more. A short “beep” will
confirm that the frequency entry was successful, and
the new operating frequency will appear on the Main
(VFO-A) frequency display fields.
Example 2:
Enter 7.100.000 MHz into the Sub band (VFO-B):
1. Press the [
B
] button.
2. Within five seconds (blinking the
imbedded orange LED) of pressing
the [
B
] button, press the [
ENT
] but-
ton to engage the direct frequency entry process. Now,
beginning with the “10 MHz” digit of the frequency
(the leftmost digit), we will enter the required digits of
the frequency to be entered into the Sub band (VFO-
B) register.
3. Press, in order, the digits of the operating frequency,
using the [ BAND
] buttons (which have the frequency-
entry digit or decimal point on the right side of the
slash bar). In this example, enter
[

4. Press the [ ENT
] button once more. A short “beep” will
confirm that the frequency entry was successful, and
the new operating frequency will appear on the Sub
(VFO-B) frequency display fields.
A
DVICE
:
If you attempt to enter a frequency outside the operat-
ing range of 30 kHz ~ 60 MHz, the microprocessor
will ignore the attempt, and you will be returned to
your previous operating frequency. If this happens,
please try again, taking care not to repeat the error in
the frequency entry process.
Using the
[
SUB VFO-B
]
knob
You may change the Main band (VFO-A) frequency in 1
MHz steps. If you press the (VFO-A) [
BAND
] button, the
1 MHz steps will be applied to the Main band (VFO-A)
frequency. The imbedded LED in the (VFO-A) [
BAND
]
button will glow Red in the latter case.
When tuning in 1 MHz steps, clockwise rotation of the
[
SUB VFO-B
] knob will increase the frequency, while
counter-clockwise rotation will decrease the frequency.
Using the UP/DOWN Switches of the
Supplied MH-31
B8
Hand Microphone
The [ UP
]/[
DWN
] switches on
the supplied
MH-31
B8
Hand
Microphone may also be used
for manually scanning upward or
downward in frequency, respec-
tively.
The microphone’s [ UP
]/[
DWN
]
switches utilize the tuning steps of
the Main Tuning Dial knob; moreover,
when the microphone’s [
FAST
] key is
pressed, the tuning rate increases by a
factor of ten, in a manner similar to the
effect of the transceiver’s front-panel
[
FAST
] button.
A
DVICE
:
In the AM and FM modes, you may independently set the
tuning steps when using the [
UP
]/[
DWN
] switches. To set
new tuning steps, use Menu items “ 121 tun AM STEP ”
and “ 122 tun FM STEP .”
