==============================
International Radio -IRI Labs 1/2 tuning rate Mod
on Digital B unit - (X54-1840-000)(B/2)
Cut D106,D105,D110, and D109
Digital B unit is located behind the Sub display in a shielded Box
Its easy to do but a bit of a pain to reverse..
================================
I guess someone found they wanted to reverse it.
I'm going to check what the tuning rate of my Yaesu FT-ONE is. That seems better
