c. Signal to KY-57. The signal is applied from the J-3513/U J6 pin D
through the CX-13064/U to the RT RETRANS jack pin D, through the RT, and out
the X-MODE jack pin G. Then is applied back through the CX-13064/U to J-
3513/U J6 pin M, through K3 relay to J3 pin K, and through the CX-13061/U to
the KY-57 pin E (Figure 67). (Trace these circuits on your system diagram.)
