FunctionControls:
Function Button controls the features marked in Blue under the control button.
Press the “FUNC” button and immediately press the desired feature button to
perform the task. For instance, if you wanted to turn on the HI CUT feature to
tone down the speaker. Press “FUNC”, then press “+10 Khz/HI CUT” button to
enable HI CUT.
The “FUNC” button can also be used to program many other features of the
radio. These features will be covered in greater detail later in this manual.
Page 3
FunctionProgrammability:
The “FUNC” button controls the features marked in Blue under the control
button. The “FUNC” button also opens the programmable features of the radio
via a control menu. The programmable features of this radio can be set by
Computer, or by manually entering the Function Menu.
To open the Programming Mode via the Function Menu, Press and Hold the
“FUNC” key for 2 seconds. Press the “FUNC” key again and again to select the
different programmable features. Example: Press and Hold the “FUNC” key for
2 seconds and the “FUNC” icon will apear on the display. Press the “FUNC” key
again and the “STP” menu will indicate the Frequency Tuning Step of 10 Khz. By
turning the Channel Selector, the step tuning will change to the desired
frequency steps.
Press the “FUNC” key again to select another item. Change setting with the
Channel Selector. After 5 seconds of no activity the new setting will be saved in
memory. The Display will show each Option and Setting to the right side.
STP (Step Tuning Programming) or (Frequency Tuning Step)
This menu is to set tuning step while adjusting CLARIFIER knob
Options Available: 10HZ 100HZ 1KHZ 10KHZ (Default: 10HZ)
CLA (CLARIFIER) Mode Setting (Default: RT)
This menu is to set functions of the CLARIFIER knob. Options are as follows:
+ FIN: Fine Tuning. When this option is selected, users can Only Fine Tune
the Receive Frequency by rotating the CLARIFIER knob.
Option “1” will appear on the LCD.
+ RT: When this option is selected, users can adjust Both Transmit and
Receive. Option “2” will appear on the LCD.
+ T When this option is selected, users can Only adjust the Transmit
frequency., Option “3” icon will appear on the LCD.
PUS (PUSH Function Setting)
This menu is to set functions of the PUSH knob. Options are as follows:
+ COA: When this option is selected, PUSH and turn CLARIFIER knob to
adjust COARSE tuning. Option “2” will appear on far left of the LCD.
+ T: When this option is selected, PUSH and turn CLARIFIER knob to change
Only the Transmit Frequency. Option “3” will display on the far left of the LCD.
Page 4
+ STP: When selected, PUSH function will change Frequency Tuning Step
of the CLARIFIER knob. Press In on the Clarifier knob and the frequency
step setting will blink. (Default: is STP)
Change as desired.
ASQ (Automatic Squelch Control) (Same asAQ on Mic) Default is OFF
TOT (Transmit Time-Out-Timer)
Sets the TOT timer. When the mic is keyed longer than the TOT time set,
the radio will stop transmitting on that single keyup.
The speaker will emit a prompt until the PTT key is released and keyed
again. This setting keeps the radio from being keyed up for long periods
of time and heating up the Final Transistors.
Options: 30-600s Step: 30s (measured in seconds)
Default: 180s
SC Scanning Type Selection (Default is SQ)
Sets Scan Mode. Options are as follows:
+ SQ: When SQ is selected, scan would stop when a valid signal is
detected. The radio would resume scanning after signal disappears for 5
seconds.
+ TI: When TI is selected, scan would stop when a valid signal is
detected. The radio would resume scanning 5 seconds later, whether
signal disappears or not.
TSR (Transmit SWR Protection)
Sets whether to enable Transmit SWR Protection function or not.
+ ON: When ON is selected, the radio will detect the SWR of antenna.
Once the SWR is beyond the SWR setting, the radio will not transmit
The speaker will emit warning prompt. Then, “HI S” will display on the
LCD to remind you that the antenna SWR is too high.
+ OFF: When OFF is selected, SWR Protection function is disabled.
NOTE: To protect the radio from long transmissions under high SWR, the
radio will automatically start SWR Protection once the SWR Value is
higher than 20:1. (Default: ON) (SWR=<10:1)
*TDC (Power Supplied Voltage Protection)
This menu is to choose whether to enable Power Suppy Voltage
Protection function or not.
Page 5
DISP (Default is TF)
Sets the content displayed on the LCD on transmit.
+ TF: When TF is selected, LCD displays transmit frequency on transmit.
+ SR: When SR is selected, LCD displays SWR value (Ex: “1.2” on LCD).
+ BAT: When BAT is selected, LCD displays DC Voltage (Ex “13.8DC” on LCD).
+ TOT: When TOT is selected, LCD displays TOT remaining (Ex: 170”on LCD).
RBF (ROGER BEEP Frequency Setting) (Default is 1050 KHz)
Sets Roger Beep Frequency. (300KHz—3KHz. Shift step is 10Hz).
RBT (ROGER BEEP Holding Time) (Default: 500ms)
Sets Roger Beep Holding Time, (50ms - 1000ms). Shift step is 50ms.
CFR (CW Side Tone Frequency) (Default: 1050Hz)
Sets CW Side Tone Frequency. (300Hz- 3KHz) Shift step is 10Hz.
TON (Transmitting Single-Tone Frequency) (Default: 1050Hz)
Sets Transmit Single-Tone Frequency. (300Hz -3KHz). Shift step is 10Hz.
PROGRAMMING VIA PC
The Alpha 10 “Max” Can also be programmed via a Computer using an
Optional USB Cable and Software. Programming via Computer allows
more flexibility by offering the option to change Operating Frequencies
and Channel Spacing. Of course, all other programmable settings can
also be set via the software.
The USB Cable plugs into a small Programming Jack inside the Radio.
The Software is Windows Based and comes with Drivers to support the
cable.
