3. A-band (FM on 2m, 1.25m, 70cm) B-band (All Modes, All Frequencies)
(Dual Band Display)
(Single Band Display)
[A/B] to switch between A-band and B-band
[F], [DUAL] toggles between single and dual display

4. VFO vs. MR [MR] = Memory [VFO] = Variable Frequency Oscillator
Recall a Memory
Frequency or Name is Displayed
Memory Number is Displayed
[VFO] = Variable Frequency Oscillator
Key in a frequency
Memory Number is NOT displayed

5. Simplex vs. Repeater Simplex: Rx and Tx on the same frequency
Example: Rx on MHz, Tx on MHz
No Tone
Repeater:
Rx on one Frequency
Example: MHz
Tx on an Offset Frequency
Example: MHz (+ 0.60MHz offset)
Tone (most repeaters require an access Tone)
No Tone (blank), T, CT, or DCS (DCS is not widely used)
Tone Frequency (example: 94.7Hz)

6. Repeater Concepts Rx Tx K6DCS 147.225 + 94.8Hz 147.825Mhz 147.225MHz
(only if tone = 94.8Hz) Rx Tx
K6DCS
94.8Hz
Mhz
MHz
Castro Peak
Standard Offset = 0.60MHz
PTT
Tx = MHz T=94.8Hz
Rx = MHz

7. STEP Frequencies may be selected in increments of the “STEP”
Default for 70cm (440MHz) is 25kHz
Some repeaters are not aligned to 25kHz increments, for example, MHz To set STEP to 5.0kHz:
[F], [STEP]
Select 5kHz with top knob
Don’t forget [MNU], OK

8. How to Key-in a Frequency
Select Band-A, select [VFO] mode, then press [ENT].
You will see _ _ _ _ _ _ displayed.
Key in the 6-digit frequency (examples: , , ). The decimal point will automatically be entered.

9. Activating the Tone Functions
Press [TONE] to switch the Tone function on ( T is displayed)
Press [TONE] again to select CT for CTCSS (Encode/Decode) or DCS, or turn the Tone functions off.

10. Multi-function Key [MNU] (“Do it” or select Menu) – Press down
ESC
[MNU] (“Do it” or select Menu) – Press down
[OK] (“Do it”) – Important after making a selection!
[ESC] = Escape (Don’t do it) – to the left

11. Selecting a Tone Frequency
While the Tone function is ON, press [F], [TONE]
Turn the Tuning control to select the desired tone frequency
Press [OK] or [MNU] to complete the selection
