Both systems are virtually the same hardware configuration:

  • SCOM 7330 controller.

  • Six cavity duplexer
  • Astron SS50M power supply

    Remote Base Channel Selection
    Due to the Marlborough site's high location, the remote base can hear many repeaters on the same frequency. The remote base TX PL is set to the one for the primary location shown in the table, which corresponds to the repeater listed first. Other repeaters that might be heard are in the rightmost column. Although you may hear the other repeater, you won't be able to transmit into it because the link TX PL tone is set to the primary repeater.

    Currently, the remote bases on the two systems are programmed identically. This may change as the Boxborough site cannot access several of the sites further South.
