PROGRAMMING YOU 245XLT FOR THE
N.S.W. GRN.
For those of you with a 245xlt, here is the correct way to
program your scanner for 400Mhz trunking for the N.S.W. GRN.
Firstly you should know that the manual has several mistakes
in it, and in some parts is not clear or doesn't explain
properly how to perform some functions with the scanner. I
found this when programming the scanner for 400Mhz systems.
The manual doesn't explain what the bAS (or base) frequency
is or what the offset is. If you follow the instructions
below, you shouldn't have a problem. Honestly, if you have
trouble getting it to trunk with these instruction, quit
now, sell it while you can. |
PROGRAMMING
THE GRN
Although the
UBC245xlt is not designed to trunk the New South Wales
GRN, which is based on Motorola Smartzone trunking, it
will if programmed correctly. It is therefore necessary
to follow these programming steps precisely in order to
maximise performance. Key presses are done in
RED. Important
information is done in bold type.
|
Step 1:-Turn the UBC245xlt
on. After which press and hold the
TRNK key for a few
seconds. This puts the scanner into trunk
programming mode.
|
Step 2:-If you have been
successful, you will hear 2 beeps and the screen
will be clear with the exception of bank and trunk
icons flashing on the LCD display.
|
Step 3:-It is now necessary
to select the bank you want to use for trunking.
Bank selection is made by pressing the appropriate key
(1-0) on the
scanners keypad. Only one GRN site should be entered
into each bank. Also only channels assigned to that bank
can be accessed. For example if you choose bank 3, only
memories 61-90 inclusive are available to the user.
|
Step 4:-After the desired
bank has been selected the screen will change and
display display one of the six option (as shown below,
with the appropriate mode underlined). It is now
necessary to select the type of system (trunking
protocol) you wish to monitor. As the GRN is based on
the 400Mhz band, which is UHF, the display should be
toggled to show E2 UHF. This is achieved by
pressing the arrow up (▲) or
HOLD key or alternatively, the arrow down (▼)
or LIMIT key until
the display shows the correct system. Press
E to complete this
stage.
The six trunking options are; E1 Type 1 800Mhz
Motorola
E2 800
Type II 800Mhz Motorola
E2 900
Type II 900Mhz Motorola
E2 Hi
Type II VHF high band 137-174 Motorola
E2
UHF Type II UHF 406-512Mhz Motorola

Step 5:-From the GRN
frequency data supplied on the GRN frequency page
on this site, select the site you wish to monitor. Enter
all the frequencies listed for the site using the
scanners keypad. To advance to the next available memory
slot use the up (▲) or HOLD.
If a keying error is made simply press the (
. ) ATT
key twice to start over. remember to enter all the
channels for the desired site, including the
control/data channel.
|
Step 6:-After all the
frequencies have been entered and are correct, it is
necessary to enter the base frequency as well as the
channel offset. This is achieved by pressing the
DATA key. The
display changes with the letters bAS and the frequency
406.000 is presented on the LCD display. So for the
UBC245xlt to function properly on GRN you must change
the frequency to 415.575, followed by the
E to enter the
altered base frequency.
|
Step 7:-Next, press the
DATA key once again.
The display will show OFS 50.0, change this to 12.5 by
pressing 1 2 . 5 on
the keypad, followed by the E
key. The programming sequence is now complete for that
bank.
|
Step 8:-To start searching
the GRN for active talk group press
SEARCH. You must do this
before you can enter talk groups manually into the scan
lists. By pressing manual while trunk searching, the
scanner will go to the first clear scan list memory.
Simply enter in a talk group from one of the pages of
the services on this site using the keypad (e.g. 13024)
followed by the E
key to enter it. |
NOTE. Due to the upgrading of the GRN in N.S.W. , some sites
now contain frequencies in a second and third channel range
(413.000Mhz - 415.500) , which means the 245xlt WILL NOT
TRACK these frequencies in a GRN trunk site. You have to add
these conventionally in your scanner, and scan them
conventionally. There is no current way the 245XLT will
include these frequencies into the tracking function. Uniden
does not intend to make future 245xlts track dual range
systems. Upgrade to a 780xlt to get around this. |
Hints and
Tricks You Should Know
Ok
there are a few hints you should know about the 245xlt.
Many of these are taken off the
Strong Signals
message board and the 245xlt mailing list.
1:-
If you get a flashing key lock symbol, and the scanner in
unresponsive to any key press, it means you have the scanner
in REMOTE mode. Press and hold the 'E'
key for 2 seconds to unlock the remote mode.
2:- To reset the radio (this is a FULL reset! you have been
warned!), turn the radio off and push and hold '2',
'9'
and 'MAN'
and turn the radio on. This will reset the radio and erase
all memory content.
3:- If you intent to scan a trunking bank in a conventional
manner, lock out the data channel, but if you return to
trunk tracking, make sure you lock back in the data channel,
or the scanner won't trunk that bank.
4:- Someone suggested programming the same trunking site in
2 separate banks. One for scanning with scan lists of talk
groups, and another for general talk group searching. this
way when you search, and talk groups you have locked out are
recognised when searching.
5:- Yes you can program conventional channel, such as 468Mhz
police, in a trunk bank in unused channels. The scanner will
scan the trunking system, then scan the other channels, all
at the same time. this is faster then having the
conventional channels in a separate bank.
6:- For those who wish to tap the discriminator of the
245xlt, the chip number is MC3361cd and the pin in 'PIN 9'
7:- For those who wish to make their own power cable, the
scanner is CENTRE
positive!
8:- Yes the 245xlt will work with the well know TRUNKER
software. Just set the scanner up for the BC895 (the latest
version of TRUNKER 3.8.1 supports the 245 directly) put it
into 9600 baud transfer mode, put it in remote mode and
start trunker!
9:- Read the manual CAREFULLY! Doesn't matter how
experienced you are with scanners, this one is different
from all the rest. Don't skim read the manual, you won't
work out how to drive the 245xlt.
Even experienced scanner
users have problems with this scanner at first!!

Other Tips
EarPhone Jack Modification
(doing this mod will void your warranty! You have been
warned! You are responsible if you stuff your scanner up!!)
For more audio power, say to run an external speaker (and it
is a bit quiet when you run an external speaker), the
limiting resistor on the headphone jack centre pin can be
bridged out with a piece of wire, OR You can run a piece of
wire from the ground of the BNC connector to the outer ring
(ground) of the earphone jack. Keep in mind that this will
drain the battery faster.
12:- Need to program in a trunking site for areas you can't
receive, for example if you are going on a trip somewhere?
The 245xlt won't let you add Talk Groups to a trunk bank
without it being able to receive the control (data) channel.
There is an easy way around this problem. When programming a
bank, add your local data channel frequency to the bank of
the system. Set up the trunk bank and hit search. The
scanner should lock onto the data channel, but not track due
to different frequencies of the site you want to program.
Hit MANUAL and it should then stop on the first available
talk group scan list channel. From here, you can enter all
the talk groups you like. When you have finished, take the
scanner out of trunk mode, and go the the channel you set
for your local data channel, and delete it (in manual mode,
hit '0' then enter). Now when you get to the new sites
location, you should be able to scan the talk groups lists,
instead of wasting time trying to find new talk groups for
the area. |
