Resurecting my 148 GTL St's or NWST, one board has 2 IC's IC1 and IC5, other has no IC1 or IC5, the radio I am working on does not have the IC's, CBTricks has the schematics for the board with the IC's, everything else looks identical, but cant find schematic for it, or just go by the IC board version of the schematic and specs?
