Original note telling of our newest repeater being commissioned:

February 20, 2021

We are now "live" on the B.A.R.C. Club's brand-new Yaesu DR-2X repeater!

This was purchased late 2020 with club funds because B.A.R.C. was eligible to participate in Yaesu's "Upgrade Program". The slightly older DR-1X will be moved to 444.575 MHz and the callsign will be KCØLAT/R.

The BARC club 2-Meter repeater is a new Yaesu System Fusion DR-2X installed and placed in operation on February 20, 2021.

CTCSS TONE 107.2 Hz

The BARC Club's UHF Repeater is a Yaesu DR-1X under the callsign KCØLAT. The DR-1X was originally installed as the 2-Meter repeater on April 25, 2020, but was re-programmed and moved to 440 service on February 20, 2021 when the new DR-2X became available. The UHF repeater is capable of analog FM and Yaesu System Fusion C4FM digital modulation.

The location of the BARC repeaters is the City of Kennett Public Administration building, 200 East 2nd Street, about a block south of the city square at coordinates: 36°14'06.92', 90°03'18.86"

We wish to thank the Kennett Fire Department and City of Kennett officials who allowed us the use of their radio room, tower, and antenna.

Sinclair 4-cavity Duplexer

A duplexer is a device that allows a weak incoming signal to be isolated from the much stronger signal being transmitted by the repeater at the same time. The duplexer is placed "in-line" between the antenna and the repeater. It is really a combination "band-pass/band-reject" filter. That is why there is a 600 kHz "split" between the repeater's receiver on 146.385 and it's transmitter on 146.985 MHz. KBØUFL/R currently has the Sinclair duplexers in use. We also have a backup set of WACOM duplexers available for use.

Henry VHF Amplifier

We are also fortunate to have a Henry VHF amplifier connected in the transmit signal path of the repeater. It is used to boost the output signal of the repeater to make it stronger.
