Waikiki Trolley and Multiple Users
System Type: LTR Standard
RF Band: 400 MHz
Introduction
This LTR system is located in Waikiki and has numerous
users including the Waikiki Trolley and area hotels. Armed with
a Radio Shack Pro-97 scanner, I was able to scan through the upper
UHF band and note down and confirm logical channel numbers assignments
for the following frequencies. System frequencies may not be related
to one another, as we get a whole wide array of different users
on this system.
System Layout
Single site system located in Waikiki.

Monitoring This System
Any scanner with LTR trunking capability can be used to monitor
this system.
System FrequenciEs
The following page lists system frequencies in LCN order.
Frequencies must be programmed in the correct channel slot as
indicated in order to hear system traffic. Failure to do this
will result in your scanner tuning into a wrong transmission or
completely miss a transmission altogether.
The talkgroup ID format for an LTR system is AA-HH-UUU, where
"HH" is the home, or main, channel that the user is
assigned. The talkgroup ID one way of determining a systems logical
channel numbering (LCN) order. When an LTR system is idle, all
transmissions will be done on the home channel. However, if the
home channel is in use and there are multiple users who share
the same home channel wants to use the radio system, other radios
will "trunk" to different frequencies within that
particular system to carry on the conversation.
The big caveat then, is that even if the LCN order might appear
correct, the frequencies entered might not be related to the system
you're monitoring. If the home channel is busy and the radio needs
to trunk to an alternate channel, but the alternate channel in
your scanner has an incorrect or no frequency, your scanner will
not track the system properly.
This is what I suspect with this system, but have not encountered
any situation where the radio had to trunk to a different frequency.
Currently working to refine and compare information between what
I have and what's on the FCC database.
