6. If necessary, use the number keys to enter a
new Offset frequency and press ENT. The S
in Step blinks.
If you try to program an offset frequency
in the UHF-Hi bands (806-960 MHz), the
scanner ignores the entry.
7. While the S in Step blinks, repeatedly press
or to select the step number: 5.0,
6.25, 10.0, 12.5, 15.0, 18.75, 20.0, 25.0, 30.0,
31.25, 35.0, 37.5, 40.0, 43.75, or 50.0 kHz,
then press ENT.
8. Press PGM.
UHF-Hi (806-960 MHz)
To program 800 MHz Motorola trunking:
1. Press PGM then TRUNK to enter the ID
program mode.
2. Press FUNC, then press or . The bank
number increases or decreases by one. If
you hold down or , the bank number
increases or decreases continuously.
3. If necessary, repeatedly press MODE to
select “Motorola.”
4. Press FUNC then 3. NORMAL appears.
5. Press or to select NORMAL or
SPLINTER and press ENT. If you are
uncertain about the base frequency, use
NORMAL.
The base frequency in NORMAL is 851.0125
MHz. The base frequency in SPLINTER is
851.0000 MHz. . If you cannot receive with
the NORMAL setting, change to SPLINTER.
EDACS Trunking Setup
EDACS (GE/Ericsson) systems transmit Talk
Group ID data on a dedicated control channel.
Scanning requires clear reception of the
control channel at all times, so EDACS systems
generally have a smaller usable area. You
can manually select the data channel, but an
external antenna can greatly improve EDACS
scanning. If you are programming frequencies
for an EDACS sysstem, you must store them
in the Logical Channel Number order (usually
listed as LCN#).
LTR Trunking Setup
LTR systems, assign each frequency a Home
Repeater (HR) number, and are frequently
programmed with unique ID codes for each
radio. LTR Talk Group IDs are organized in a
specic order, and to scan, you must program
the frequencies in HR order. LTR systems are
used primarily by businesses, such as taxicabs,
delivery trucks, and repair services.
LTR systems use a Home Repeater as part of
their Talk Group ID.
To save a correct Home Repeater:
1. Save the LTR channels in any order.
2. Set the bank to Open mode.
3. Manually select LT channels and watch the
LTR data on the display.
Your scanner displays the LTR Talk Group
ID and a number preceded by “R.” The “R”
number is the Home Repeater number for
the transmission.
4. The assigned Home Repeater channel must
equal the Home Repeater number. For
example, R12 must be programmed into
Channel 12.
