[TrunkCom] Rebanding has begun on Motorola trunked systems

[David McCormick]

Some rebanding developments have been made by Wayne H.:

Radio Shack Trunking Scanners with programmable tables:

Here is the table to program:

ChLO ChHI Step Offset Base

440 559 25.000 440 851.025000

000 719 25.000 0 851.012500

720 759 25.000 0 848.000000

815 831 25.000 0 846.625000

958 958 25.000 958 868.975000

961 1022 25.000 0 843.400000

This is meant to support systems whether they are in the process of 
transitioning from 866MHz freqs or have already switched over and only 
use 850MHz frequencies. The two systems which have been mentioned in 
other threads on RadioReference (Alabama and Vacaville, California) have 
made complete transitions. Vacaville specifically was using 866 and 
immediately moved off them to the 850MHz freqs.

To simplify programming, if your system has rebanded and does NOT use 
any frequencies above 862MHz you only need to program the two ranges below.

ChLO ChHI Step Offset Base

440 559 25.000 440 851.025000

000 719 25.000 0 851.012500

GRE America Trunking Scanners:

The GRE scanners will support rebanded Motorola 3600 trunked systems. 
This is done by setting up a custom table for the system object 
("TSYS"). I believe there are certain GRE models that do not have 
programmable custom tables (100 and 200?) so unfortunately this solution 
may not work for you. If someone can provide more information I'll 
update my post accordingly.

To update the custom tables for the GRE radios you need to navigate to 
the system object. To get there via a TG hit PGM, EDIT, CURR, down arrow 
once to select the TSYS, ENT, press FUNC then down arrow to jump to the 
bottom, arrow up once to highlight "T Tables", use left or right arrow 
to choose "Custom", and then ENT. You now will have access to each line 
of the custom table where you'll input the information given in the 
linked thread above. Press SEL and then type in the values. Make sure 
they are done in order. When complete press "Save" each time to make 
sure each stage is properly stored. Now you're ready to go!

Please post programming questions in this forum. To help others, do not 
PM me with questions. Thank you.

Uniden scanners:

You will need to wait for a firmware upgrade if they provide one for 
your specific model. These models do not currently support custom tables.

 >Pass the word, at least two systems have been discovered to be using 
newly rebanded frequencies and no longer are being trunk scanned 
correctly using the current trunking scanners.
