The MMRA operates twenty-one repeaters and one APRS digipeater at thirteen locations in Eastern and Central Massachusetts.
There are also several affiliated repeaters in our network. These systems are not operated by the MMRA,
but are capable of linking into the MMRA network.

The MMRA Operating Guide provides information on how to operate on MMRA repeaters.

The first table shows special linking states at certain times during the week.
Repeaters are normally linked according to the second table below.

You can click on the highlighted locations below for more information about each site.
You can sort the table by various fields by clicking on the highlighted column header.

About our site codes: You will notice that each location has a three letter site code. One controller at a location uses this code on the air to announce a change in status. For example, when Quincy links, you will hear "Q C Y Link 1 Up". When there are multiple controllers at a location, each one needs a unique identifier. At least one controller will match the location-based code. The hub controllers identify as HUB1 and HUB2. The 900 repeater at Marlborough West identifies as "MRX".
