IRLP Node 7448 (W5MOT Repeater, Oak Hill, TX: 147.320 Mhz PL 114.8)

I maintain a 2-Meter IRLP node connected to the W5MOT repeater in Austin, TX. It has great coverage of the greater Austin, TX area.

The node is open to all hams. There are no access codes.

This node is user accessible, which means anyone can punch in any four digit node or reflector number and connect with any other IRLP node in the World.  Feel free to explore to your heart's desire.

Please follow these acceptable use policies when using my IRLP node:

  • Please ID before and after using the node. (Ex: "This is KF5KBZ, switching nodes")
  • To connect, simply key your transmitter on the repeater frequency (standard plus offset). Using your touch tone pad, input the four digit node number that you wish to connect to.
  • To disconnect, key your transmitter and touch tone 73. Please pause for 2 seconds after you key the transmitter before you speak or enter touch tones. This allows the connection to complete across the network and helps avoid dropping syllables or words from the start of your transmission. It will also ensure that touch tones are decoded properly.
  • Please pause between transmissions to allow other stations to call or disconnect.
  • Always disconnect the node when you are finished with your QSO.
  • All connections will time out and disconnect if there is no local activity within 30 minutes.
  • If the node is connected and you wish to connect to a different reflector or node, please ask if anyone locally is using the node. If there is no response, feel free to disconnect and connect to the reflector or node of your choice.

Information About the Node and Repeater

IRLP node 7448 is linked to the W5MOT repeater located in Southwest Austin, Texas. The repeater frequency is 147.320 MHz and requires a PL tone of 114.8. It is a Motorola MSR-2000 with an ACC RC-850 controller. It runs about 45 watts to an antenna on a hill whose base elevation is 912 feet above sea level. The antenna is up 350 feet on the tower for a total of 1,262 feet above sea level. It covers all of metropolitan Austin and beyond. The repeater has a backup generator that starts automatically if commercial power is lost.

The location of the repeater antenna is on the Freescale Campus in Oak Hill. If driving west on 290 by the 290/71 "Y" in SW Austin, look to your right. You can't miss it. It's quite large. It's located close to the Natural Gardener.
