The vault on the right is the home of the "W6PWT" repeater.  The site is owned and operated by "ComSites USA, Inc." and they very generously donated spaces in their vault and antenna positions on their tower to the City of Norco and the Corona/Norco Amateur Radio Club.  The vault operates on commercial power and has a backup generator for emergency power.  The vault is air conditioned and this asset helps to keep the repeater up and running 24/7.  In addition to housing the CNARC repeater and commercial units, the vault also houses a receiver, hardwired to the Corona/Norco Fire Departments which provides improved reception for units which may be transmitting on the other side of the hill.

The repeater operates under the call sign of "W6PWT" on a frequency of 147.060 MHz , with a PL of 162.2 Hz.  The repeater is maintained by members of the Corona/Norco ARC, for additional information contact:

Note! The site has subsequently been purchased by :  Crown Castle Inc.

This is the Emergency Power generator that supplies power to both of the Vaults in the event of a Commercial Power failure. Specifications on the generator are not available at this time.

For details on usage by the City of Norco and RACES organizations, and cost of operating the CNARC repeater see the following City document:

In this picture, you see the four filters comprising the duplexer, which allows the repeater to simultaneously listen (receive at 147.660 MHz) and talk (transmit @ 147.060 MHz) on the same antenna.  Specifications for the duplexer will be supplied at a later time. The small brown box, to the right, is an attenuator that drops the output power from 10 watts to less than 4 watts which has proven to be adequate for local area coverage. The copper strap in the top of the picture is grounding for elements of the repeater.

This is the insides of the CNARC repeater console.  The top panel is the "S-Com Controller", it is a bare bones type controller.  It has no telephone patch, and no voice ID, there is no separate control receiver.  The second panel is a "test panel" and is not connected during normal operation.  The third panel, with the screen cover, is the transmitter.  The transmitter has a power output range from 10 to 100 Watts,  the level is set to the lowest point (10 Watts) and is further attenuated (to 4 Watts) via an attenuator at the output of the duplexer.  The fourth panel is the receiver mounted on slide out rails.  The blue box on the right, adjacent to the transmitter, contains the logic required to interface the levels specified between the controller and the receiver and transmitter.  The fifth panel is another part of the checkout hardware used to functionally test the repeater, most of the capabilities of this panel have been disconnected and are not required in this configuration of the repeater.  The sixth (bottom) panel is the power supply and operates on commercial power to supply the voltage and current requirements of the transmitter, receiver and the controller.

This picture shows the antenna tower and the antenna mounted at the various levels.  The CNARC repeater antenna is mounted at the topmost level on the far right of the picture.  It is actually a dual-band antenna (Cushcraft AR-270) and performs very well over a 360 degree range.  The vertical antenna to the left of the of the 2 meter is a 1.2 Ghz co-linear and is connected to the site via hard-line coax. It is not connected to any hardware at the site, but could be used for future applications. It is also club property.
