CE-22 Program Software
7-2: DDec Type (DCS Decoder Type)
This command selects the manner in which
DCS is to be decoded.
Fixed = Decodes the type selected in 7-1
only (Normal or Inverted).
Auto = Decodes both types (Normal and
Inverted)
Press the SPACE bar to select the desired
DCS Decoder Mode.
8. Squelch
8-1: Sql Ofst (Squelch Offset)
The Squelch Offset function provides a
means to fine-tune the VXR-1000 squelch
level on a channel-by-channel basis, with-
out having to perform a full alignment.
The available values are an arbitrary scale
of 0 to 255. Use the Space bar and the Back-
space key to increment/decrement the
Squelch Offset level.
Note: Although the Squelch Offset range is
between 0 and 255, the squelch threshold
will be close to saturation if the value is set
to about 100 or above. Therefore, you will
observe no significant difference in squelch
threshold between the values of 100 and 255.
9. Encryption
9-1: Encryption
When ON, the VXR-1000 operates in the
"Encrypted' mode on this channel. The en-
cryption type is compatible with the encryp-
tion system used in the Vertex VX-10 (FTT-
15 module), VX-200 (FSU-1083), VX-400
(FVP-25), and the VX-500/510 (FVP-22)
models.
Press the SPACE bar to toggle Encryption
ON and OFF.
10. Channel Spacing
10-1: W/N (Wide/Narrow Channel Spacing)
This function selects the channel spacing en-
vironment in which the VXR-1000 operates.
Wide = 25 kHz Channel Spacing, ±5 kHz
Deviation
Narrow = 12.5 kHz Channel Spacing, ±2.5
kHz Deviation
18
Press the SPACE bar to select the desired
channel spacing environment.
11. Input Modulation
11-1: Mod In (Input Modulation Selection)
This function selects how the VXR-1000 will
utilize and apply audio signals which are to
be transmitted to the associated portable
radio.
Mix: Any audio being transmitted by the
microphone on the mobile radio
connected to the VXR-1000 will also
be transmitted to the portable on the
other band. If a second microphone
is connected directly to the VXR-
1000 and is also keyed simulta-
neously with the microphone of the
mobile, the audio from both micro-
phones will be mixed and transmit-
ted to the portable.
Mono: The VXR-1000 will only select audio
from the microphone which first had
its PTT key pushed. Audio from the
other microphone, if its PTT key is
pushed while the first microphone
remains keyed, will be ignored.
12. Mobile Monitoring
12-1: MBL Moni (Mobile Audio Monitoring)
This command determines whether or not
the receive audio from the connected mo-
bile radio will be routed to the VXR-1000's
EXTERNAL SPEAKER jack.
Press the SPACE bar to toggle the audio be-
tween ON and OFF.
13. Transmitter Power
13-1: Tx Pwr
(Transmitter Power Output Selection)
This command selects the desired power
output from the VXR-1000 on the current
channel. The available values are 0.5, 1.0, 2.5,
and 5.0 Watts.
Press the SPACE bar and the Backspace key
to increment/decrement the Transmit Pow-
er Level.
