The Two Meter and UHF Dual Band Repeater System

Our Main AMARC repeater system is also a dual band repeater on Two Meters and UHF. Both repeaters are interfaced together.

Both repeaters transmit FM at 146.925 and 444.550 mhz, and both modulate a CTCSS tone encoded at 192.8 hz.

They receive FM at 146.325 and 449.550 mhz, and have a decode a CTCSS tone frequency of 192.8 Hz.

With this repeater system you can talk in on either the 2 meter FM repeater, or the UHF FM repeater, and you can copy everything on either repeater outputs.

NOTE: This repeater system is open to all amateur stations.

The Six Meter AM Repeater System

Our Second AMARC repeater system is a 6 Meter AM with and it’s back-to-back UHF FM repeater. Both repeaters are interfaced together.

With this repeater system you can talk in on either the 6 meter FM repeater, or the UHF FM repeater, and you can copy everything on either repeater outputs.

The 6 meter AM receiver is a RCI-5054DX transceiver and receives at 50.400 carrier squelch, and the UHF FM repeater receives at 449.750 mhz, with a CTCSS decode frequency of 192.8.

The UHF repeater transmits FM at 444.750 mhz and has a CTCSS tone encoded at 192.8 hz.

The 6 meter AM transmitter at 50.500 mhz is located in our Barnhart, MO tower in order to prevent de-sens to the 6 meter receiver in High Ridge.

The 6 meter AM transmitter is a RCI-5054DX transceiver, driving a Mirage 150 watt RF amplifier, and has 80 watts carrier output, and swings to 150 watts peak to peak.

With this dual repeater system you can talk in on either the 6 meter AM, or on the UHF FM repeater.
NOTE: This repeater system is open to all amateur stations.

The High Ridge UHF Remote Base Repeater System

Our third AMARC repeater system is called a “Remote Base Repeater System”, which consists of a UHF repeater, interfaced to a Multi-band, Multi-mode simplex radio.

The UHF FM repeater receives at 449.850 mhz with a CTCSS decode frequency of 192.8 hz, and transmits at 444.850 mhz with an encode CTCSS tone of 192.8 hz.

This repeater is interfaced to a Yaesu FT-857D radio by remote DTMF commands.

The multi-band radio interface controller is a ICS Linker II DTMF controlled switching system. The FT-857D radio has been programmed to operate on the bands of 2, 6, 10, 12, 17, and 20 meters. The output on the 6 to 20 meters is 100 watts. The 2 meter output is 50 watts.

At this time the remote bands in High Ridge are only 2 Meters and 10 Meters because the muli-band antenna is not on the tower. Still working on that project.

NOTE: This AMARC Remote Base repeater system is limited to club members use only, but the UHF repeater system is open to all amateur stations. If you are not a club member, and you hear a member using the remote base, you can feel free to break-in, and use the remote base, as a guest, for bands you are licensed to use.

The Barnhart UHF Remote Base Repeater System

“Identical to the High Ridge Remote Base Repeater System 3, except for the repeater frequency difference”

Our fourth AMARC repeater system is called a “Remote Base Repeater System”, which consists of a UHF repeater, interfaced to a Multi-band, Multi-mode simplex radio.

This UHF FM repeater receives at 448.725 mhz with a CTCSS decode frequency of 192.8 hz, and transmits at 443.725 mhz with an encode CTCSS tone of 192.8 hz.

This repeater is interfaced to the Yaesu FT-857D radio by remote touch-tone commands.

The multi-band radio interface is done with a ICS Linker II DTMF controlled switching system. The FT-857D radio has been programmed to operate on the bands of 2, 6, 10, 12, 17, and 20 meters. The output on the 6 to 20 meters is 100 watts. The 2 meter output is 50 watts. Club members will receive a list of frequencies and codes, and changes.

NOTE: This AMARC Remote Base repeater system is limited to club members use only, but the UHF repeater system is open to all amateur stations. If you are not a club member, and you hear a member using the remote base, you can feel free to break-in, and use the remote base, as a guest, for bands you are licensed to use.
