Sigh, I didn't notice that spreadsheet for some reason ... I did set
the one for PL and I've been looking at it all AM.
I tested VHF and UHF this morning and fixed a couple of problems. I
probably made multiple errors that cancelled themselves out or
something as I'm now able to decode my test cases for lowband,
highband and UHF.
I'll have a look at the spread sheet I'll probably answer questions
that I don't even know I have yet...

I posted the X9000 freq calc .xls with sheet protection on (w/o password) to keep cell formulas from being accidentally overwritten. Trust me it happens.
It can be unprotected and the formulas can been seen.
I left the graphic representation of the byte data in it to help illistrate the composition to those that dont quite get bit data.
The how the 10 bit, 8 bit and reference bits are stored in the 3 bytes per freq value and where they are stored in a mode's 24 byte set are on the "info" page of the 1st version (LB only) Dennis found somewhere (RR maybe) that I posted years ago. I dont know if that made it here but Dennis posted a link to it early in the discussions. I think I still have a .psf version I made and sent to Casey back then too. I'll see if I can find it and post it
I have discovered more than it covers and some corrections may be needed. I stopped researching it shortly thereafter.......
After things began to fall in place, the LB was the simplest. Only one PIN switchpoint for TX and one for RX, and no C1/C0 calcs.
One rule the RSS uses for all bands is that 6.25khz reference is used for any freq divisible by 6.25, even 440.000 or 52.525. The 5khz reference can be used of course in calculation but the main divisor, hence the 10 and 6 bit values change for that frequency. Edit the value, recalc the CS and away ya go. The radio doesnt care it will generate the same freq for either calculation.
For compatibility, I made the calculator comply with the RSS's 6.25khz rule.
The PITA was sorting the C1/C0 values used by the VHF and up
calculations.
