Welcome to the KK7AV UHF EchoIRLP Repeater System Website. This repeater system utilizes a uNode (micro-node) for VOIP connectivity to both IRLP and Echolink networks. It is an open system located in Las Vegas, NV and may be used by any licensed Amateur Radio Operator.
*Update* The KK7AV UHF Repeater System will not be back on the air for a few more weeks. There are some additions and modifications that I want to implement while the system is down and more convenient to work on. However, this will delay things a bit. One of the additions to it will be a 900 MHz port so local users with 900 gear will be able to access the system using that band.
*NOTE* The KK7AV UHF Repeater went off the air on Tuesday, May 13, 2008 at 08:45 Pacific Time. It is being relocated to a better location and should be back on the air within a couple of weeks or less, hopefully with improved coverage.
Repeater features: - The repeater requires a CTCSS (PL) tone of 114.8 Hz in order to gain access to it. It's an open repeater with access to BOTH Echolink and IRLP linking systems. There are no special access codes. For IRLP, simply key-up and dial the node number. For Echolink, key-up, and prefix the node number with the pound (#) sign. To disconnect from either type of connection, simply key-up and dial, "73."
- The repeater is located in the north-western corner of the Las Vegas valley. The transmitter puts out 80 Watts of power into a 6-cavity duplexer. The duplexer delivers a clean and solid 35 Watts to a 9dBd gain, omni-directional antenna. The base of the antenna is approx. 40 feet above the ground. This gives good local handheld transceiver coverage for a radius of about 5 miles depending on line-of-sight, obstructions, etc. Mobile transceivers can be used from most areas within the valley.
- To find out the connection status of the repeater, the DTMF command, "**" (star sent twice) will cause the repeater to announce whether or not a connection is established, and if so, to which node or reflector it is connected.
- To shorten the system courtesy delays and hang timers (handy while utilizing cross-band linking to access the repeater, etc.), key-up and send the DTMF character, "B" on your keypad and then un-key. The repeater will report back, "System timers short." To return the repeater back to normal, key-up and send the DTMF character, "A" on your keypad and then un-key. The repeater will report back, "System timers long."
- To find out the current time, the DTMF command, "AC" will cause the repeater to announce the time. This is usually accurate to within 100mSec. of NIST Time Source!
- To place an immediate callback to an incomming connection request, while already connected somewhere else, the DTMF command, "*69" (star 69) will cause the repeater to disconnect from the current connection, and then immediately connect to the incoming connection request.
