If a Saber II model (ex H43QXJ7139CN) is potentially able to support a bandsplit of 136-174 (according to Batlabs model breakdown chart) is the 136-174 bandplit option identified when the codeplug is built or is it particular to that individual radio. In other words any model H43QXJ7139CN can have a bandsplit of 136-174 provided the codeplug is built with that specification. Sorry for my ignorance and thanks for the help.

I think you are asking whether it is a function of the software or Hardware that tell the radio its bandsplit option. Really it is both. The model H43QXJ7139CN could be either a HI (146-174)or LO (136-150.8 ) Band Split. The RSS tells the radio its bandsplit configuration and this could be completely incorrect if someone misprogrammed it.(Band-split not in agreement with the modules installed).
So, the first thing I do when I receive an unknown radio is to open it up and look at the P/N's on the various modules. This gives me solid proof of the units hardware capablilty. The VCO is the critical component in this version as it determines the HI-LO Bandsplit. Other parts PA , FSD, 2 Pole Filter can be made to operate slightly ouside the original bandsplit limits with maybe slightly reduced specs. but they will function.
There are some that say they can squeeze extra coverage out of their Saber VHF Hi-Splits to cover the entire 2 Meter Ham band
(down to the 144 region) but this "UNIQUELY" varies from radio to radio and personally my attempt at this ended up with a SABER where the VCO would not lock on anything below 146. I had to acquire the correct VHF Lo-split modules and install them in order for the Saber operate that range. As I said "This varies Radio to Radio" so you might get lucky.
Then there is also the option of programming a Hi-Power VHF as a Low-Power VHF and extending the receive of a 146-150.8 to 146-174. I have never done this since my operations are limited to the 144-148 Mhz.
You might could squeeze in a listen to the weather channel every once in a while if you desire.
This Saber VHF model can be confusing for the beginner. Hopefully I made some sense out of it all.

The VCO/Synthesizer is the largest module in the Saber. It is square and located beside the rectangular Gold piece (PA Module.) It has the P/N stamped on the bottom of it so you have to remove it to actually read the numbers. The rear cover needs to be removed also as the screws that hold the VCO in are attached to it.
The P/N (VHF Version) will be one of two:
-NLD8201A 136-150.8
or
-NLD8210A 146-174
