You can select any desired step setting. UNDERSTANDING YOUR PRO-92’S MODES You can program each channel with any of seven receive modes.
20-522.fm Page 29 Friday, May 19, 2000 4:35 PM With few exceptions, such as the VHF Aircraft and Marine bands, almost every other VHF or UHF radio system uses some form of coded squelch. By far, PL is the most popular mode among non-trunked systems. For most scanning use, try setting PL mode for all non-trunked channels. If you operate the bank in open mode, the scanner will display the appropriate code. AM Mode This sets the scanner to receive transmissions using amplitude modulation (AM).
20-522.fm Page 30 Friday, May 19, 2000 4:35 PM When the scanner receives a transmission on a channel set to the PL mode, it first decodes the PL tone included with the transmission. In the Open mode, the scanner stops on the transmission and displays the PL tone on the bottom line of the display (or displays None if no tone is included). In the Closed mode, the scanner only stops on the transmission if the PL tone matches the tone that you specified for the channel.
20-522.fm Page 31 Friday, May 19, 2000 4:35 PM LTR (E. F. Johnson) Mode This sets the scanner to decode the talk group ID’s used with an LTR system. This is a trunking system used primarily by business or private communications service providers, such as taxi cabs, delivery trucks, and repair services. LTR systems encode all trunking information as digital subaudible data that accompanies each transmission.
20-522.fm Page 32 Friday, May 19, 2000 4:35 PM Motorola Mode This sets the scanner to decode the talk group ID’s used with Motorola trunking systems. These systems are used by business and public safety groups to efficiently allocate a small number of frequencies (as few as 5) to many groups of users (as many as several thousand). To do this, each group of users in the system is assigned to a specific talk group. For example, the east side patrol officers might all be assigned to talk group 2160.
20-522.fm Page 33 Friday, May 19, 2000 4:35 PM For example, Police East Patrol might be assigned to group 12, making the full Fleet, Subfleet ID be 000-12. To properly map the raw Type I data to the correct fleet-subfleet format, you must program the correct fleet map into the scanner. Fleet map information is widely available on the internet for most Type I systems in use. Type II systems talk groups are identified by a 5-digit number. Valid talk group IDs are divisible by 16.
20-522.fm Page 34 Friday, May 19, 2000 4:35 PM When there is activity on an EDACS system, that information is sent out on the control channel. The scanner decodes the ID for the active talk group. In the Open mode, the scanner then goes to the transmission and displays the talk group ID on the bottom line of the display. In the Closed mode, the scanner only goes to transmissions that have ID’s that match a talk group ID that you have stored in the bank’s talk group ID list and have not locked out.
20-522.fm Page 35 Friday, May 19, 2000 4:35 PM OPERATION TURNING ON THE SCANNER AND SETTING SQUELCH 1.
