[Trunkcom] MultiNet

 Hmm, LTR seems kinda silly the way I understand it, if each agaency is
assigned a "base" freq. Suppose you have five freqs. assigned to an LTR
system and more that 5 on the system, wouldn't this cause problems? I
realize that they don't always stay on the same channel.
 I may be blind, but I don't see any real advantages of LTR over a standard
freq. assignment.

Multi-Net adds several features designed for Public Safety, such as
emergency functions, priority access, and wide-area coverage.  Although
both LTR and Multi-Net use sub-audible data signalling on the voice
channels, Multi-Net's signalling is different than LTR, and in a sense is
a different trunking type altogether.  Multi-Net also uses a control
channel (LTR does not), which is basically one of the voice channels
continuously transmitting sub-audible data (and unlike other trunking
formats, the control channel can simultaneously be used as a voice
channel).  Scanners that track LTR cannot track Multi-Net as it is a
different format.

They are made by the same company, EF Johnson (now owned by Transcrypt).
But, the LTR format is licensed to several companies who make LTR
equipment (Motorola, Kenwood, Uniden, etc).  Mutli-Net is only provided
by EF Johnson.
