The Sandusky Radio Experimental League (SREL) maintains three repeaters that provide reliable portable and mobile radio coverage throughout the Sandusky area and beyond. All repeaters are open for use by licensed amateur radio operators at any time.

Our Repeaters

6 Meter Repeater

53.350/52.350 MHz - 107.2 Hz

The 53.350 MHz repeater is located at the club facility and was built by SREL members in 1998. The system features a 100-watt continuous-duty Motorola Micor Compu Station integrated with an RC100 controller. As a single-site repeater, it operates through a Decibel Products DB-4032 low-band commercial duplexer that has been modified for 6-meter operation. The repeater is connected to a Diamond 6-meter antenna mounted at 85 feet and fed with ½-inch hardline coaxial cable.

2 Meter Repeater

146.655/146.055 MHz - 110.9 Hz

The 146.655 MHz repeater is located at the club and was originally built and placed on the air by SREL members in 1976. It has been in continuous operation ever since. Over the years, the repeater has undergone several upgrades to keep pace with advancing technology.

The original system featured a commercial tube-type receiver and transmitter, with a custom-built controller designed by club members. This configuration served the Sandusky area reliably for many years. In the late 1980s, the system was modernized with a solid-state Spectrum Communications receiver and transmitter, delivering 30 watts of output power and controlled by an S-Com 7K controller.

In 2005, the repeater was again upgraded to a commercial Tait Series I 25-watt repeater, which remains in service today. It continues to use the original S-Com 7K controller and Phelps Dodge duplexer from 1976. The repeater is connected to a four-bay Sinclair commercial antenna mounted at approximately 75 feet, fed with 7/8-inch hardline. For emergency communications, the system is also equipped with a battery backup.

440 Repeater

444.3750/449.3750.055 MHz - 110.9 Hz

The 444.375 MHz repeater was first placed into operation at the club in 1990 and later that same year was relocated to a water tower at the intersection of Columbus Avenue and Strub Road. The original system consisted of a 40-watt Motorola Mocom 70 commercial repeater and duplexer, converted for amateur use and operated with an S-Com 5K controller.

In the early 2000s, the system was upgraded to a 75-watt Motorola Micor Compu Station, enhancing both performance and reliability. The repeater is now located at the Erie County EMA Office on Columbus Avenue, adjacent to the fairgrounds, where it continues to serve the local amateur radio community.
