Are you sure you're not thinking of the VX7?  What you describe is 
exactly how it works for that radio, but the VX8 makes a departure from 
the three-block protocol that the 7 (and others of that vintage) use. 
The block missing is the one with the mods in it.

Rick did some work on the VX3 trying to figure out the soft mod but I'm 
not aware that anything ever came of it.  Personally, I think its likely 
that Yaesu didn't carry that "feature" forward past the VX5/7 days.

Yep, the 2,5,6, and 7 all have that one block in between the header and 
the memory data, but the 3 and 8 do not (which is the source of my 
skepticism)

Hmm, well, I'm not too worried about the liability issues.  I certainly 
plan to throw up a huge blinking buzzing warning about doing something 
to your radio that you might regret.

I think that it will be fairly easy to re-use the same key/value 
mechanism underneath the covers without making the UI (for settings and 
mods) a big mess of knobs.  That's what I meant about using this system 
for generic settings and mods.  It will definitely need a little 
augmentation to allow it to be organized.

Thanks for the feedback!
