52 Trunking Operation
Notes:
• Base and offset frequencies vary for each type of
trunking system. You can get information about
these frequencies for the trunking system you want
to scan using
www.trunkscanner.com, other Inter-
net sources, or locally-published guidebooks.
• The scanner automatically decodes subaudible data
it receives in the VHF band.
• If you try to enter an offset frequency in the VHF and
UHF-Hi bands (137–174 and 806–960 MHz), the
scanner will ignore the entry.
Follow these steps to program Motorola trunking fre-
quencies in the UHF-Lo band.
1. Select the bank, then press PGM to enter the pro-
gram mode.
2. Store the base frequency into channel 00 of the
bank you selected, then store the trunking frequen-
cies into subsequent channels in the same bank.
3. Press TRUNK then repeatedly press MODE to select
MO (Motorola).
4. Press FUNC then 9 . 12.5 kHz (the default offset
frequency) appears.
5. Repeatedly press FUNC then 9 to select the offset
frequency you want ( 12.5 kHz , 25.0 kHz , or 50
kHz ).
Note: Offset frequencies above 50 kHz do not
appear and are used only for subaudible decoding
mode.
6. Program the trunking frequencies (see “Program-
ming Trunking Frequencies” on Page 50).
