This thread caught my attention and got me looking at some cables I have here. I've got a rib to radio cable for LPE/Jag etc as well as a ribless cable that I borrowed from a friend. Took apart the DB9 hood and the board in there is easy enough to replicate... A MAX202, a handful of caps and a voltage regulator. Thought it was going to be an easy job until I took apart the actual radio connector... there is something else buried in the corner under epoxy and I can't tell what it is... it's an 8 pin IC of some sort with what looks like maybe a couple of caps on it. It's hooked to GND and VCC which goes up to the lower up the 2 pins at the top of the connector. Anyone know whats buried in there?
