[Motorola] VHF MAXTRAC/RADIUS

[K0DAN]

Programming up some old MAXTRAC & RADIUS mobiles.

The RSS fields allow you to type in "split" channels (e.g. 159.1275) however 
when you hit "enter" the software rounds up or down so you end up off freq. 
and not exactly where you want to be.

Is there a "cheat" to get these freqs programmed in accurately? I think 
holding the ALT key (?) lets some ham freqs get programmed in out of band? 
There's another trick using a hex editor? Will any of these (or other) 
techniques let MAXTRAC/RADIUS go to these splits, or are these radios simply 
to old to do something that sophisticated?

Using the "warp" function is nmot a desirable solution.

Thanks!
