McIntosh Communications

McIntosh Communications, a Las Vegas 2-way Dealer, expanded into the Salt Lake area around 1999. Known for having a very agressive sales force, McIntosh operates LTR Trunking in the 450 MHz range.


Ensign Peak - SLC

Ensign Peak has less of a coverage range than Farnsworth, and other sites in the Oquirrh's, but it puts in a stronger signal into Downtown. Most, if not all, of the traffic on this system seems to be at The Gateway.

Farnsworth Peak - SLC

Update 5 May 2011 - From recent montitoring, it appears that McIntosh has been actively migrating users off this system, probably putting them on MOTOTRBO (digitized audio). Fleets I am no longer hearing have been greyed out. I am just beginning to analyze MOTOTRBO and NXDN signals I have found in the 450 - 470 MHz range, and will add that info to this page when I have something useful.

Understanding LTR

If the concept of trunking is completely unfamiliar to you, start here first.

Typically, the display while receiving an LTR system will read something like: 1-02-156

Interpreted, this means area bit 1, the fleet's home channel is 02, and the fleet's ID is 156.

The area bit can be either 0 or 1, and all channels in use by the trunking system will have the same area bit. If if a frequency has overlapping coverage between two LTR trunking systems (and there is a case of this in this area), one system must use 0, and the other 1.

Both the home channel and fleet ID identify the fleet. 1-02-156 and 1-01-156 would be two separate fleets.

1-02-156 will home on the trunking system's channel 02, with the speaker silent until a radio on fleet 1 02 156 begins transmitting. If channel 02 is being used by another fleet, and a user on fleet 1-02-156 begins transmitting, the system will automatically (transparent to the users) send the fleet to one of the other channels.

Each LTR system has a unique table, which assigns a frequency to a channel number. Channel numbers are from 1-20, allowing an LTR system a maximum of 20 channels. The table is programmed into the system, and into each subscriber unit. Changing the table would require reprogramming every single radio on the system.


Any additional information you could provide on these systems would be appreciated.
