Radio Shack PRO-96 Setting Squelch for, Trunking

The control channels for some Motorola trunked radio systems may change on a day-to-day basis. To ensure that you will not miss traffic when the control channel changes, enter all the known control channel frequencies into the channel storage bank. If the control channel changes, your scanner will automatically lock on to the new control channel. If you do not know which system channels are used for the control channel operation, we recommend that you enter all the system frequencies into the same bank.Ô

When the scanner decodes the Motorola control channel and finds talkgroup activation on a voice channel, the scanner displays the control channel memory location on the top line, the received frequency with VC (voice channel) on the second line, the bank and control channel memory location number on the third line and the Motorola talkgroup ID number on the bottom line.!

Setting Squelch for

Trunking

For optimal receiver performance when scanning both trunked and conventional systems, we recommend that you set the squelch close to threshold. Navigate to a programmed channel in manual mode. While the channel is idle, turn the squelch control fully counterclockwise. You will hear a loud rushing noise from the speaker. Turn the squelch control

Ô NOTEÔ

Frequency fleet map and talkgroup information are also widely available on the Internet.

For example, at www.trunkscanner.com.

! IMPORTANT !

To listen to the transmission, the mode setting of the trunking control or system channels must match the mode setting of the associated ID list (MOT for Motorola and APCO- 25, or ED for EDACS). When an ID code is received, the ID list for the bank is searched, and if found, the text name stored for the ID appears in the scanner’s display. If not found, scanning resumes immediately unless the bank is in open trunking mode.
