Hub Defeats PL
Direct Frequency Enabled
200
This feature is only applicable to portable radios when a Vehicular Adapter
is used. Use the UP/DOWN arrow keys to enable/disable the Hang-Up
Box (HUB) Defeats PL feature. When Hub Defeats PL is enabled, PL/
DPL will be disabled when the microphone is removed from the hang-
up box. In the SECURE mode, the radio will go out of Proper Mode
Detect. This allows for monitoring of a Conventional channel to
prevent transmission during another conversation.
The default is Enabled.
Use the UP/DOWN arrow keys to enable/disable this feature. If the
Direct Frequency flag is enabled, the user can enter the Direct
Frequency in the CONVENTIONAL PERSONALITY screen (F4/F6/F3)
and modify it. If the Direct Frequency flag is disabled, the Direct
Frequency will be copied from the Conventional Rx frequency.
The default is Disabled.
