A friend has a Uniden scanner ( don't know exactly the model) wants to know
if it can be re-programmed to include trunked frequencies.
Also some police forces are now using frequencies that step and skip(?) so
that they cannot be heard. ( don't know the exact term of this) , but can
the scanner be programmed to receive these type of frequencies anyway ?

Last but not least, Can ALL Uniden scanners be re-programmed using a
computer and is it fairly easy ?

Thanks for all the help.

Depends. Newer models of Uniden scanners are for the most part programmable
to receive trunked frequencies. Some
are not trunk capable.

You need to know what trunking system is used in your area as the
programming steps require setting the scanner to receive
the correct system (type and other configuration options).

The BC780XLT is a bit complicated to program correctly. But once set, you're
set. You need the frequencies which need to be set into the correct order
and in the right positioning otherwise the system will not work properly to
receive, and you also need to know the talkgroups for better handling.
Didn't get much co-operation from local scanner enthusiasts (they spent alot
of time on smart ass remarks) so I did it myself and works perfectly.

The BC780XLT is alphanumeric so once the frequencies are set it they can be
labelled.

It's a bit complicated but over time becomes fairly easy, but not
nessesarily less complicated.

Do not mix trunked and ordinary frequenices in the same channel.Use a
channel bank to store trunked frequencies and another for ordinary ones.

The BC245XLT is also programmable. But does not have alphanumeric tags.

Both the BC245 and the BC780XLT can use software if you use a 9 pin serial
cable

The biggest problem is that the trunked frequencies have to be analog
otherwise you need to get a digital capable scanner to handle APCO-25, and
if the police frequencies are on a digital system other than APCO-25, you're
out of luck. Most police
frequencies in the larger cities (but not all of them) are digital so that
the bad guys don't get an idea that Sgt. Wiggum is out
on patrol if if he's not eating donuts and drinking coffee.
