Using IRLP Experimental Reflectors​

IRLP experimental reflectors are single-channel reflectors that operate independently of the IRLP network yet still compatible with IRLP nodes. They may provide cross-linking to other VoIP networks, other special services, or any private or public function implemented by its owner. Their four-digit reflector numbers begin with 0.

Since they are not part of the IRLP network, experimental reflectors are not subject to IRLP guidelines. Unlike conventional nodes and reflectors, connections are not authenticated unless authentication is deployed externally by the owner. Accordingly, experimental reflector connections are disabled by drfault. Node owners may allow connections by adding the following line to the $CUSTOM/environment file:


them running:


as root to reload the IRLP software with the change.

To connect, dial the reflector number as for a conventional reflector. From the command line, connect by running:

experimental_call expNNNN

where NNNN is the reflector number.

Experimental reflectors are private resources and may be closed to general use. The IRLP Experimental Reflector Page lists operational reflectors that are open to the public.

Alabama Friends, University ARC Nets: Latest Updates

Effective immediately, the Alabama Friends Net and University ARC Thursday Night Net are moving to IRLP experimental reflector 0088 and AllStar node 48017. EchoLink users may continue to connect to W5MGM-L (node 548713). The Micro-Node reflector, which hosted the nets on IRLP since 2017, was removed from service in June and the AllStar bridge that has been in use is no longer available, making these changes necessary.

IRLP node owners must allow experimental reflector connections, which are disabled by default. See Using IRLP Experimental Reflectors to learn more.

IRLP Returns to Tuscaloosa

University ARC IRLP node 4719 is back in service on the club’s 145.210 W4UAL repeater in Tuscaloosa.

Along with the return of IRLP connectivity comes the club’s return to its own Thursday Night Net, which has continued without the club during its extended absence.

A hardware failure brought down the IRLP node last November. Additional hardware failures, access restrictions during construction and a number of other setbacks and difficulties kept the node out of service for approximately 10 months.

The W4UAL 145.210/144.610 repeater, located on the University of Alabama campus, requires a 103.5 Hz PL tone for access. The University ARC Thursday Night Net meets weekly at 8 p.m. Central time on the club’s repeater, on various other connected repeaters and simplex frequencies around Alabama and beyond, and on IRLP, EchoLink and AllStar. A list of participating RF and online nodes is on the UARC Net page.
