Frequency Agile Remote Base - Which allows control operators to link to any 2 meter frequency.
The remote base remains offline most of the time, but is available upon request.
EchoLink Node#19024 in Knoxville, Tennessee. The repeater system is composed of two 100 watt GE Mastr II Stations connected to a ARCOM RC-210 3 port repeater controller and a CAT WX-250 Weather receiver with Specific Area Messaging (SAME) alert technology. This provides timely NOAA WX Alerts during Severe Weather. NOAA broadcasts are broadcast on both repeaters. (The WX receiver is Currently out of Service)
This is an open repeater system, and all are welcome to use it. Feel free to use this repeater as a normal repeater, but be prepared for someone from anywhere in the world to connect in the middle of your QSO via echolink, please welcome them in.

The KB4REC 6-m & 70-cm Repeaters are linked together on both 53.470 MHz (- offset) with PL of 100Hz and 444.5250 MHz (+ offset) with a PL of 123.0 Hz. This is an open repeater system, and all are welcome to use it. Feel free to use this repeater as a normal repeater, but be prepared for someone from anywhere in the world to connect in the middle of your QSO, and please welcome them in.
Below is some information about general commands and how to connect to other nodes using the KB4REC EchoLink repeaters: The repeater controller has DTMF muting enabled, so to pass your touch tones you must proceed all echolink commands with “# The controller will store your tones and then regenerate clean tones over the air for the echolink system.
Tune to 444.5250 MHz (+ offset), PL 123.0 Hz or 53.470 MHz (- offset) PL 100 Hz. Listen before accessing the system since others may be using the link. Push and hold your PTT button, then on your DTMF keypad push # * (pound star), then release both buttons, to determine if you are in range of the repeater. The repeater will transmit an identification message in response unless someone is connected. Send #08 (pound 08) to see if anyone is connected. If a station is connected, it will come back with the call, if not, you will hear "disconnected".
To test the quality of your signal into the repeater and quality of the EchoLink network connection, you may access a test station node (called ECHOTEST) by entering station node number #9999. We recommend that all new users try this test node the first time you try EchoLink to help you become familiar with system use. This node will repeat your transmission back to you so you can hear your transmission quality. Remember to press # # to disconnect when you are done.
To make a call, press in your push to talk and hold it while entering # followed by the node number of the person you wish to call or enter a code number from the list below.
DTMF CODE DESCRIPTION
# Node Number Enter the 4 to 6 digit Node Number that you'd like to connect to.
# # Once connected, this will Disconnect the link.
# * Station info. Will not play if a station is already connected.
# 00 Random connection to Computer User, Link or Repeater

When it is accepted by the gateway, listen for connection messages. The gateway will acknowledge when the connection is made. Monitor for other traffic because you might connect in the middle of a QSO. If the link is busy, it will say, "system is busy" and then it will disconnect. Let the carrier drop before you begin to talk. Just remember to wait about 2 seconds after keying before you start to talk. THIS TIMING IS VERY IMPORTANT TO SUCCESS. This is necessary due to delays in your radio, the repeater, and in the transmission over the internet. Remember that you are on the radio so use proper protocol. Please ID before accessing the system, and ID as normal (at least once per 10 minutes) during a QSO. To end the QSO, transmit # # then you should hear the "disconnected" message.
