CHAPTER 7: MENU Items
The BCH-270 supports 51 menu items for setting various parameters that determine the operation
of the radio. This chapter details each of these items and how each item works. KEEP IN MIND,
MANY OF THESE FEATURES CAN BE ADJUSTED USING THE WINDOWS BASED PC PROGRAMMER.
To access the menu list:
Press F and then quickly key the menu item number or press the UP/DOWN button to find the
menu item. If the menu list has not been accessed since power up, item 00 – ANI is displayed.
Once the menu item is found, press the F button to begin setting the item function. Press the
UP/DOWN button to select the item function. Press the F button to confirm the item function
setting. Press the *V/M button to exit the menu list and revert back to the previous operating
mode.
During operation, the current menu item displayed will be the last menu item that was displayed
when the menu list was exited.
00 – ANI (Automatic Number Identification)
The ANI menu item allows for turning ON/OFF ANI RX decode operation of the radio.
If decoded, the calling radio’s unique ID is displayed.
01 – SQL (SQUELCH Level)
The purpose of the squelch control is to mute the speaker when no signals of sufficient
strength are present. With the squelch level (0-9) correctly set, the speaker will only un-
mute when there is a strong signal present. The higher the squelch level, the stronger
the signals must be to un-mute the speaker. The appropriate squelch level depends on
the ambient RF noise conditions.
02 – POWER (HIGH or LOW)
This menu item allows for changing the radio’s power level. The two options are HIGH (5W)
and LOW (2W) Power. Each channel group, A or B, has its own setting.
03 – REV T*R (Reverse Frequency)
The reverse frequency menu item allows for quick reversal (SWAP) of the programmed TX
and RX frequencies. In VFO mode this reversal is governed by the programmed OFFSET.
When the radio is set for reverse, the REV icon will be illuminated.
04 – VOX.SWI (VOX SWITCH)
This menu item allows for turning ON/OFF the VOX feature. VOX stands for voice activated
transmit. VOX.SWI works with the VOX Level menu item 24. When VOX is active, the VOX
level determines what mic level (1-10) will PTT the radio. Level 1 requires a loud voice,
whereas Level 10 requires softer voice. When VOX is on, the IVOX icon is illuminated.
