Echolink Cross-Band Repeater Project
November 2005 - The cross-band repeater system is INACTIVE / HARDWARE FAIL (03-27-2007) on west peak of the Socorro mountain. See a conceptual diagram here. See the coverage area of the proposed system below.

147.50 (100Hz) simplex (default)
446.50 (100Hz) simplex

Note: For best operation, use 147.50. If you are in Socorro, use 446.50.

Echolink Node: 29253
Simplex/Echolink Status: Active
System is available for use.

Echolink is software that allows amateur operators to communicate via the internet.  It works by VoIP or Voice over IP technology.  It will work with internet connections as slow as an analog dial-up line. All one needs is a windows computer, sound card, microphone and speakers. This system allows repeaters and simplex stations to be linked together. The result is much like that of the Mega-Link system here in New Mexico. Users can enable or disable links using the DTMF tones on their radio giving them the ability to contact stations all over the world with a 2 meter radio. Hams can talk computer to computer, computer to repeater, or repeater to repeater. 


TARA's objective for running a simplex station with an active echolink linking system is to encourage the practice of amateur communication at New Mexico Tech and to demonstrate the applications of computer and internet technology to the amateur radio community. It has been an ongoing project to give NMT students a way to operate the TARA station from their dorm rooms with only a computer, microphone, and ISD's local area network system. With this technology now available to TARA, amateur radio operators at NMT and the surrounding area can benefit from it.
