is a photo of the repeater system as it was installed. This the front view. The repeater is
at the top of the cabinet, then right below it is the control shelf,
then the Motorola "Spectra-Tac" UHF control receiver.
The Crescend power amplifier is just above the power supply. The repeater
and control equipment is powered by the 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.
There is an addtional cavity filter in line with the receive side,
located in the rear of the cabinet.
Below is a rear view of the repeater.
The SD-224 antenna is mounted on the top of the 200 ft tower, as seen below.
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!
The NEW WB4GBI 145.43 repeater features the Yaesu
"System Fusion" digital mode! A NEW Yeasu DRX-2 Fusion repeater was
acquired on 12/27/2017. The repeater, antennae, feed lines,
and cabinet with duplexer was installed on 4/13/2018. The original
power amplifier was removed in January 2019, after it failed and was
transmittering spurious emmissions. The replacement PA and repeater
were re-installed and placed in service on April 27, 2019.
