The back story is that after the TADD-1 I started working on a divider,
but instead of the PIC-based code decided to use a CPLD instead. It was
a fine idea, but involved me learning a whole new craft (PLD
programming) and despite help from some on the list, I never got things
to the state where I was comfortable with either the hardware or the
software implementation. So, the TADD-2 slipped to the back burner.
Then, two things happened: (a) I found myself *needing* a divider, and
(b) Rich McCorkle offered his version of TVB's code that could handle
both 5 and 10 MHz inputs; my need was connected with a 5 MHz standard.
By the way, for those new here, "TADD" stands for many things:
Totally Awesome Distribution Device (TADD-1)
Digital Divider (TADD-2)
Divider Dongle (TADD-2 Mini)
Digital Distribution (TADD-3)
At TAPR, we're working hard to use our acronym resources wisely.
