Tips needed for driving Uniden EZ133XLT - Help

Postby timmoore46 » Tue Dec 31, 2013 1:01 pm

Only just got it and I seem to get jammed in the selecting the saved channels in the 'hold' button commands and how the Srvc button interacts... I'm a complete newbie to scanning....

So the question is how do I get in to get the Scanner to acutually scan ?

I can select the 'Air' band easy enough but it all goes down hill from there....

the 1 2 3 buttons are fine but after that its pure luck what I get to work next.... *LOL*

Any thoughts most welcome ! A Tip sheet would be great !

Are you setting the squelch to just stop background noise?? If the squelch is open to noise it will not scan...

Press (Srvc/Fav) until the bank you
want to scan displays.
When HOLD icon appears, press
(Hold) to resume scan.


Only one bank can be scanned at a time.
The banks can be changed in the following order;
EMG > FRN > PMR > MRN > V-LO > FM > AIR > V-HI > UHF


To switch scan modes between
Service scan and Favourite scan:
Press & hold (Srvc/Fav). In Service
mode the FAV icon does not show
on the display. In Favourites mode
the FAV icon shows on the display


Press (Hold) at any time to pause scan on the current
frequency. HOLD icon appears.
Use the / keys to go to the
previous/next frequency in the
service bank or the previous/next
channel in the favourites bank.
Press (Hold) again to resume scan.



With airband, I can see two issues, one it coversd the whole of the airband, including the information beacons which simply push out the same few words of weather info etc & the other is that the whole band is in 8.33khz, whilst some of the channels are in 25khz steps..

108.0000 - 136.99166 steps 8.33khz, mode AM

Many many thanks ! That is the info I needed ! I will print it out and try out your tips ! I've been struggling so these are pure gold dust to me !

As a matter of interest I noted that it eats batteries at a surprisingingly fast rate so I modded it.

I found that my recharegables did not work as 3.6V was the minimum it would wake up on also +5V was fine, so using a Rapid Electronics part number 20-1080 (5M long 2.1mm DC Extension lead) to add a DC power socket to the empty battery compartment and plug in an external +5V DC supply. normally it takes about 80mA with occasionally a bit more so a 7805 regulator works fine with a 470 mfd electrolytic capacitor +16V rating and a 2k resistor hung on its output, I have loads od 2.1mm plugged power supplies hanging around so the I can leave it scanning all day. For mobile use a small 6V Lead-Acide battery is fine. Its worth noting than the battery compartment connections take very kindly to getting soldered.

My daughter got her pilots license last March and its nice to listen in when she visits, got me started with an ambition in Airband listening.

Many thanks again,

73's

Many thanks ! I've printed out an extra copy so I can write comments on it !

A good few years ago I used to write Quich Start Guides for complex Equipment we manufactured.

I always started with a Noddy guide to getting it to do something simple.

That gave the customer who had paid a lots of money for one of the these devices confidence in using it.

Each function had its own Appendix, plus a good Index and job done.

So meeting a terse Mensa challenging manual makes me cringe ! Yes it meets its Spec but why does it take a couple of weeks to get it working for someone who has never seen one before ! *LOL*

Rant over.... *LOL*

So your help has been very greatly appreciated !

: ))))
