Views from the rooftop (405 ft. above the street)

This is a shot from the top of the Webb building, looking straight out Richmond Road.

Another shot from the top of the Webb building, looking out Leestown Road.

A view from the roof, overlooking the UK Medical Center, looking south toward Nicholasville.

Another view from the roof, looking off of the roof over the north east corner of the building.

Still another view from the roof, this one looking directly towards Nicholasville.

One of our number one helpers, Reggie KG4NXM, and the voice of the KB8QLC repeater, Jeanie, supervising.

A testament to an excellent ground. We took a lightning hit in January 2002. It killed the antenna, but burned through the hardline directly to ground. It never saw the repeater!

Pictures of the repeater.

Yeah, I know, ya seen one box, ya seen 'em all! This is the cabinet that houses the repeater. The sticker says "DANGER! 50,000 ohms!"

The repeater in the background belongs to the Webb Companies.

With the front door removed. The duplexers are mounted on the rear rack rails, which gives us more room in the cabinet. The amplifier is mounted upside down to keep coax runs short. UHF radios are Motorola M120's from a GR500 repeater

This is a closeup view of the top half of the repeater. If you look carefully, you can see the nameplate on the amplifier is upside down. Also you get a better look at the radios. The one on the right is used for receive, the one on the left is the transmitter that drives the amp to 100 watts.

Close up of the bottom of the cabinet. The controller is a Cat700. Below that is the Kenwood GM-707 dual band radio that is the remote base. At the bottom of the cabinet, the workhorse, an Astron RM-70 power supply, and the IsoBar AC lightning protection. Note, we caught it transmitting, see the red light?

Here is a closeup of the Kenwood remote base. On the shelf, is the microphone for this radio, which is not used. This remote base interface costs less than $70 to build, and works very well with the CAT family of controllers that have two radio ports.

Here is the "octopus". Thanks to another one of the helpers John K4RBH for building this interface. It worked great first time, and makes our life so much easier in interfacing all of this stuff together.

A very special THANK YOU! to The Webb Companies for the space to house this repeater. The amateur radio community in Central Kentucky can never say enough thanks for your kind benevolent donation!
