Pro-92 vs. Pro-94

Pro-92 vs. Pro-94

Post by Brian Clar » Fri, 15 Jun 2001 21:13:00

I am looking to purchase a trunking scanner and have been looking at the
two Radio Shack offerings, the PRO-92 and the PRO-94.  How do these two
measure up against each other (other than the 94 having twice the channel
capacity of the 92)?   Which one should I get and why ?

Thanks,
Brian Clark

PRO-92 advantages:

* computer programmable - a BIG, BIG plus
* can decode CTCSS/DSC - a BIG plus
* receives LTR trunked systems in addition to MOT and EDACS

PRO-94 advantages:

* More channels (minor, you will rarely, if ever, be able to use 500,
let alone 1000 channels)
* receives some extended freq bands

Dave,

Can you provide some more info regarding this? Does that mean in the 92 I
can't group all the fire freqs in one bank, police in another? etc??? I
really like the idea of alpha tags, but organization is even more important
to me.

Thanks, Pizza Man

You can organize the Conventional (non-trunked) Frequencies in
whatever manner works for you.  All FD in one bank, all PD in another,
all EMT in a third, if that is what you desire.

For trunked systems, each SYSTEM must be in one bank.  You cannot mix
different systems in the same bank.  This applies to any trunktracking
scanner.

Dave,

Great and informative answer. I have an original Uniden Trunk tracker. I
like being able to setup TG banks within the frequency bank , as you
described. It is a great little radio. Fairly easy to use, but I'd sure like
alpha tags and AA batteries, instead of the nicad-pack.

Thanks, Pizza Man
