TEARA's NEW! WB4IUY repeater in Clayton, NC

Here, the last jumpers and connections were being made by Steve KD4WIW on the new PA board. After alignment, the PA was making better than 100 watts.

Here's a shot of part of the control system, including the refurbished S-Com 6k controller (black rack mount case in the bottom of the photo). Just above the 6k is part of the original RCA interconnect panel, and two Interalia Digital Voice recorders (in white at the top of the photo). The Interalia DVR's were originally used by the phone company to store messages. They were repaired from salvage and modified for use in our repeater application.

This is a picture of the new DC blowers added to the repeater. By using DC blowers powered from the main 12vdc buss, the repeater will receive adequate cooling even in the event of operation from backup battery power. Two blowers are attached to the PA (large heat sink), and one blower is attached to the power control regulator bank (small heat sink).
