Tx Deviation / Channel Spacing

(Conventional Personality, Frequency Options)

HGDefinitionMob%26Port.jpg

Selects the transmit (Tx) deviation and corresponding channel spacing for the current Frequency Options profile (record / row) of the current Conventional Personality. The Tx deviation is the maximum variation (in kHz) that the selected carrier - frequency can differ or swing from its un-modulated center frequency. Channel spacing refers to the allotted frequency difference between adjacent channels within a specific frequency band. DotGreen.png The radio also uses the selected Tx Deviation / Channel Spacing values when this personality is operating in Direct / Talkaround mode.

When the Mixed Vote Scan Enable field is Enabled and the Mixed Vote Scan Tx Steering field is Disabled, this field must be a match for all Frequency Options in the current Personality; otherwise the CPS considers this field’s value invalid.

When the 12.5 kHz FCC Narrowbanding Mandate applies for this codeplug, and

when the value of the Tx Frequency OR ( Direct Frequency OR TA Frequency when enabled for Direct / Talkaround operation ) falls into one of the FCC Requirement ranges.

5 kHz / 25 kHz

VHF, UHF, and 800 MHz Bands using 30/25/25 kHz Channel Spacing.

DotRed.png This selection is invalid if the following scenario is true:

When the 12.5 kHz FCC Narrowbanding Mandate applies for this codeplug, and

when the value of the Tx Frequency OR ( Direct Frequency OR TA Frequency when enabled for Direct / Talkaround operation ) falls into one of the FCC Requirement ranges.

2.5 kHz / 12.5 kHz

VHF, UHF, 800 MHz, and 900 MHz Band Analog and 12.5 kHz Channel Spacing.

DotRed.png When Tx Frequency falls within the 900 MHz Band, this is the only valid selection and this field becomes view-only.

DotRed.png This selection is invalid if either of the following scenarios is true:

(When the Rx Voice / Signal Type field is "Non-ASTRO Mode", and

when the Secure Operation field is set to "Hardware", and

when the Voice Secure / Clear Strapping field is not set to "Clear"),

Or
