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 specific 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.
