Is it possible to take one of these 162-174 Gov't split Systems Saber IIIs and program them in the 146-174 range? I have never seen a 146-174 Systems Saber III, only 136-150 and 162-174, which eliminates all of the frequencies that I use.

Thanks!

In order to gain OOB programming, you will first have to swap several internal modules first, in the proper band split you will be operating.

The VHF Systems Sabers use the same modules as the regular Sabers, same goes for the UHF version as well.

Here's a list of what you will need to swap out to lower your band split:

1. Synthesizer module(large square and shiny 'can' left-centered in the frame)

2. PA module(Lower right of frame, two tone in appearance, silver/gold anodized.

3. FDS(Filter/Detector/Switch), upper right on main board, up close to the radio's frame.

4. Filter module, upper right of frame and immediately to the left of the FDS module.

5. Antenna.... Obtain the proper antenna with the proper range yo need.

There is a post here that covers VHF modules, take a peek there to see what you are going to need to make the changeover.

Like any other major change, you will have to performa complete alignment to ensure the radio perfoms to spec.

Good luck!


Enterprize.....One to beam up!

This may not be too much help, since my knowledge is limited:

Motorola had a program for Systems Sabers using non-catalog bandsplits. I know at least one city where they have hundreds of Sabers and Systems Sabers on a non-contract bandsplit; these are maintained by an SP RSS, which the City obtained from Motorola. What you may find interesting is that I once watched some catalog Systems Sabers converted to the non-catalog split (from, from memory, 453 to 490-something) simply by running a bit of software into the radio; no hardware changes were required.

Someone probably knows more about this program than I do.

Jake-

I have purchased about 20 of the ex-Secret Service radios that had been at about 165 MHz (±). Changing no modules whatsoever, I reinitialized the radio with a 146-174 codeplug, and had 0.3 microvolt RX sensitivity at 146 MHz (and throughout the band) and also 5 watt TX output.

We have commiossioned 6 of these in our local Search and Rescue operations.

I have found that they are great for public service in the 155 MHz band, and work well in the ham band. No complaints here at all. Lately, the price has been right on this stuff, too.

Thanks for the information guys! I was hoping it could be done without changing and modules, since a factory 146-174 Systems Saber is apparently extremely hard to find!

But you will have to switch the antenna...

I think I can handle switching the Antenna, changing internal components is what had me worried..
