2017 Off-Season Museum visits may also be scheduled by appointment.

Whenever we can, we enjoy hosting members and visitors who are perhaps unable to visit us during our regular season. We will do our best to accommodate your schedule, but please be aware that we perform maintenance and updates in the off-season, with reduced staff. Allow several days notice so that we may arrange to open the museum for you, your family or small group. For large groups, please provide several weeks notice. Call 508-945-8889, or e-mail to arrange your visit.

Plan Your Visit

Plan to spend at least an hour at CMMC. When you first arrive, watch our introductory video: "Chatham Radio: WCC The Untold Story", narrated by Walter Cronkite. We have additional short videos that will enhance your visit -- each is about 10 minutes long (see our Exhibits page for their description).

Take time to explore. Depending upon your interests, you may find that you want several hours, or to take advantage of your free second-visit opportunity.

Most of our exhibits have "touch screen" panels and audio to provide background information. You can send a message in Morse code at the interactive kiosk. Children will enjoy the scavenger hunt to identify items across the exhibit space.

Spend some time in the Museum Shop, browsing the wide selection of books, logo clothing and other items.
