Pigeon Telephone established by John J. Campbell as part of the Valley Telephone Exchange. Manual switchboards and operators are housed in Campbell’s general store in downtown Pigeon.

Pigeon Telephone is sold by Campbell to oil and sugar beet salesman James Spence. At that time, the utility had 275 subscribers.

A severe sleet storm damages most of the wired network. Local farmers begin turning over ownership of their privately-strung telephone wires to Spence in exchange for repairs and significant upgrades.

Pigeon Telephone is acquired by Crawford “Ham” Spence and Robert Spence upon the death of their father James.

The last independently owned telephone line within the Pigeon exchange, the “McKinley Farmers’ Line” just north of Pigeon in McKinley Township, is acquired by Pigeon Telephone.

Pigeon Telephone is upgraded to a totally automated “cross-bar relay system”, making manual switchboards obsolete.

Pigeon Telephone is sold by the Spence family to Pigeon businessmen John E. Eichler and Willis “Bill” Hengy. By now the company has surpassed 1,200 subscribers.

Twining Telephone Company, serving the communities of Twining and Turner in Michigan’s Arenac County, is purchased from Emory and Rose Curriston. The purchase adds approximately 400 subscribers. The company is fully merged into Pigeon Telephone by 1986.

Alba Telephone Company, serving the Michigan’s Antrim County’s Alba and Lakes of the North telephone exchanges, is acquired from Ron and Hazel McGregor. The company serves approximately 500 subscribers. It is merged into Pigeon Telephone in early 1982.

Pigeon Telephone cuts over to an all-new network of buried weather-safe cable and state-of-the-art switching equipment housed at a newly constructed central office near downtown Pigeon.

John E. Eichler and local farmer James J. Christner become the sole proprietors of Pigeon Telephone. Christner continues to serve on on the present-day AVCI Board of Directors.

Agri-Valley Communications, Inc. (AVCI) is founded as a subsidiary of Pigeon Telephone to handle non-regulated communications services.

AVCI later becomes the parent company of Pigeon Telephone and all other subsidiaries in 1994.

Pigeon Telephone is upgraded to digital switching equipment to pave the way for emerging technologies including dial-up internet access.

John Eichler’s sons are appointed key leadership positions within the company. Edwin H. Eichler is appointed as President and CEO, and Neal B. Eichler is named Vice President.

Pigeon Telephone begins offering Improved Mobile Telephone Service (IMTS), which is the predecessor of modern cellular mobile phone service. Due to its superior transmission distance, many ships navigating Lake Huron and Saginaw Bay use IMTS until the early 2000s.

On December 13, the FCC awards Pigeon Telephone with a license to provide cellular phone service in Huron, Tuscola and Sanilac Counties. The license is awarded on John Eichler’s birthday, just months after his passing.

Continuing John Eichler’s vision for the future of Pigeon Telephone, Thumb Cellular is founded as a separate entity to provide cellular mobile phone service to Huron, Tuscola and Sanilac counties.

Agri-Valley Services, then known as ‘AVCI.net’, is formed as an Internet Service Provider (ISP) and begins providing dial-up services across the Thumb and northern Michigan.

Agri-Valley Services solidifies its presence as a rural broadband provider by introducing fixed-wireless broadband internet services in 2004. DSL broadband services available to Pigeon Telephone customers followed soon after. AVS is among the first high-speed internet service providers to serve homes, farms and businesses in the Upper Thumb community.

Pigeon Telephone expands to serve the communities of Sand Point and Mud Creek. It reaches a peak of 3,500 subscribers.

The AVS Tech Team is created as the computer repair and networking branch of Agri-Valley Services.

AVCI matriarch Pauline Eicher passes away. Following the death of her husband John in 1988, Pauline became the primary shareholder in the company. She began her career as a Pigeon Telephone operator for the Spence family and later managed administration duties in the corporate office with her husband, John, and into retirement with her sons, Edwin and Neal.

A new generation joins the family business. Peter Eichler, son of Edwin, and Hans Eichler, son of Neal, are appointed to the AVCI Board of Directors.

Continuing the legacy of John J. Eichler, today’s leaders of Agri-Valley Communications, Inc. are constantly evaluating bleeding-edge communications technologies and how to best serve our communities.
