So what is so important about VFO B? Doesn't VFO A have the same capability? If so, then that which is so important on VFO A can be done on VFO B. Just let the software do its job and learn to use it as designed.
I think hams spend most of their time dreaming up ways to make things complex. It is a frickin' hobby folks and no more complex than pushing a dang button. Of course, I know many hams have difficulty in doing just that and thus expect the software developers to do it for them. Grrrrrrr!!!!!
