Here is a photo of the repeater system as it was installed. The repeater is at the top of the cabinet, then right below it is the control shelf. The repeater and control equipment is powered by a Motorola "Micor" series power supply, located in the middle of the cabinet. The six-cavity TX/RX duplexer is mounted in the bottom of the cabinet.

 

The SD-224 antenna is mounted on the top of the 200 ft tower, as seen above. 

A brief history of the 145.43 repeater:

In 1982, the 145.43 frequency was originally coordinated by SERA to WB4GBI. It operated at View Park Hill (the present 145.17 site) until Tim, WB4GBI moved to North Carolina in 1987. At that time, Tim returned the frequency to SERA for re-coordination. It was then operated by several different owners, with the last one being the Kerbela Amateur Radio Service (WB4YLC).  In September of 2015, the Kerbela Amateur Service returned the 145.43 repeater coordination to the person who coordinated it originally...WB4GBI! 

 Many thanks to WJBZ for their support of Amateur Radio!
