All about the N5OAK Repeater

OHARC operates a Yaesu DR-1X System Fusion repeater with an Arcom controller. The system operates in analog mode only due to limitations with incorporating our IRLP node and utilizing other advanced audio features on the system, like squelch tail suppression, etc.   The system uses a  PL code of 114.8 Hz on both transmit and receive with a courtesy tone for an exceptionally clean and quiet signal.

EchoLink Node N5OAK-R node 485908 is now up and running and available for use. Similar to IRLP, this system will allow computer users (with valid amateur radio licenses only) to connect with the repeater.  This is usually accomplished by use of a smart phone, computer or similar device and is particularly useful for members that are outside of our coverage area but would like to participate on a net or make a contact through the repeater.

The IRLP Node 7448 is limited to club members (which is free) by use of an access code. Please visit www.N5OAK.com to sign up! IRLP (Internet Radio Linking Project) allows us to interconnect with one or many other repeater systems and individual simplex nodes world wide.  Go to http://www.irlp.net for more information.

Repeater Details – The repeater is transmitting 50 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.

Coverage Area – with a basic 50 watt mobile radio and a good antenna, N5OAK coverage extends as far north as Georgetown, as Far East as Bastrop, well South of San Marcos and as far west as Johnson City.  With a 5 watt HT and a relatively unobstructed line-of-sight path to the repeater, 10 – 15 miles is easily achievable.  And since the RF environment on our tower is relatively low, our repeater has “good ears”.   It can pick up those weak signals with ease.

The location of the repeater antenna is on the NXP Semiconductor Campus (formerly Freescale) 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! You can see the exact location on Google Maps by clicking here: https://goo.gl/maps/213uHXTsHxq

The OHARC DMR Repeater is up and running on 441.300. The repeater is located near the intersection of Burnet Road and Anderson Lane. It is connected to the Brandmeister network. Stop by the “Local” TG2 (CC01 TS02) and say hello! Or Brandmeister ID 114802 for you hotspot users 🙂
