This document shows construction and testing with cor board version 6.2; a prototype built for R&D, then in 2010 for a backup repair (FRU) serial # 44.
Some view angles of the cor board installed in a working (and standby FRU) "HUB" repeater for the 20 repeater (support). The front panel controls are easy to understand and adjust. The right shows the board flipped up for radio's PCB access as well.
The board is secured with three phillips head screws that go in the stock PL area. Those screws are a specific size, which is an M3.5 x 12 mm.
