Dtcs code, Offset frequency, Dtcs polarity

DDTCS code

Sets DTCS code (both encoder and decoder) for DTCS squelch operation. Total of 104 codes are available.

(default: 023)

OTHER FUNCTIONS 11

DOffset frequency

Sets the duplex offset frequency within 0 to 20 MHz range. During duplex (repeater) operation, transmit frequency (or re- ceive when reverse function is set to ON) shifts the set fre- quency. (default value may differ depending on operating frequency

band and versions)

DDTCS polarity

Sets DTCS polarities for transmission and reception from

“NN,” “NR,” “RN” and “RR.”

(default: NN)

DTuning step

Selects tuning step from 5, 10, 12.5, 15, 20, 25, 30, 50, 100 and 200 kHz for [DIAL] or [Y]/[Z] operation. (default value may

differ depending on operating frequency band and versions)

• Transmit : normal	• Transmit : normal
Receive : normal	Receive : reverse
