Programming Motorola Trunking Systems (Uhf-Lo) - Grecom PSR-300 Owner's Manual

Follow these steps to program trunked frequencies:
1. Press PGM and select the bank.
Note: To move through the bank selection faster, press PGM then FUNC
and hold down
sequence of PGM, FUNC then
2. Press TRUNK to enter the ID program mode.
3. Repeatedly press MODE to select Motorola, EDACS (GE/Ericsson), or LTR
(EF Johnson) system to scan. This sets the talk group ID decoding method
to be used for the bank.
Note: If you select conventional mode instead of Motorola, EDACS, or LTR,
the scanner does not scan trunked frequencies. Trunking mode not selected,
press Mode key. appears.
4. Press PGM to enter the program mode.
5. Enter the desired trunking frequency then press ENT to store.
6. To enter additional trunking frequencies as subsequent channels in the same
bank, press PGM or
frequencies. (See "Storing Known Frequencies into Channels").
Note: If necessary, press MODE to change the receiving mode.
7. Press SCAN to start scanning.
Notes:
• If you enter a frequency that has already been entered into the same bank,
the scanner sounds an error tone and displays Dupl.Freq. and the channel
number that has been duplicated. If the dual entry is an error press CL and
enter the correct frequency. If the dual entry is intentional press ENT to ac-
cept.
• You may replace any frequency by selecting the bank and channel, press-
ing PGM and entering the new frequency.
If you make an error in the entry process, press CL as often as needed to erase
the incorrect data.

Programming Motorola Trunking Systems (UHF-Lo)

You can program the scanner to receive transmissions in the UHF-Lo band
(406-512 MHz) of the Motorola trunking system. You can receive these trans-
missions by checking the trunking system's control channel. You must pro-
gram the system's base frequency and offset frequency to do this.
Note: 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.RadioReference.com, other Internet sources, or locally pub-
lished guidebooks.
