Repeaters

The WPI Wireless Association is proud to sponsor three repeaters that serve Worcester and many other surrounding communities. Both of the 144MHz machines and the 440MHz machine are currently in service and are designated as "open" to the local Amateur Community.

The W1YK and W1WPI repeaters both have Echolink capabilities. For more information about Echolink, check out Echolink.org. We maintain the standard Echolink DTMF commands which are outlined here on both repeaters.
