These are pictures of the tower at View park Hill
that show the 145.170 antenna.

Here you get a closer look at the repeater's four pole

(That's a cellular tower in the bottom-background)

After looking skyward, here are some shots of the 145.170 repeater itself.

The 145.170 machine is actually a Motorola "Micor" series repeater,
with a Wacom WP-641 4-cavity band pass/band reject duplexer.
This is a factory-made 132-150 split repeater, which was purchased back in 1995.

Here, we see a view
of the repeater cabinet.

This is the back of the repeater
with the rear cabinet door off.
Notice the three fans atop the
repeater PA for cooling the PA heatsink

This view better illustrates the contents of the cabinet.
Here , you can see the entire repeater cabinet. From top to bottom: You can see the control shelf where the plug-in "cards" are, then the receiver, then the repeater power supply near the bottom.

A brief history of 145.170...

The 145.170 repeater began it's service to East Tennessee Amateurs in Loudon county... originally a hamtronics repeater kit. Tim purchased the machine and upgraded it to a GE Mastr Pro - then re-coordinated it to a location on top of black oak ridge in North Knoxville in 1992 (at the old 147.075 site). A few years later the machine was upgraded again to the equipment you see here, and relocated to it's present site in south Knoxville, atop View Park Hill. This is a local coverage repeater, serving the Knoxville area with 100-watts ERP.
