Fusion (Digital) Network:  443.175 Repeater in Clinton Monday 7:30 pm and Thursday 7:30.  All are welcome. 

The VHF and UHF Repeaters in Clinton use Yaseu's Digital Fusion System, C4FM.  Both repeaters can support Digital (C4FM) and Analog communications.

They automatically switch between C4FM and normal FM as needed.  Reception of C4FM transmissions are not decoded properly by normal FM units.

Historical Note:  In the late 1990's, the hams that put up the original Clinton repeater were:    Hap, WB9SHS (SK), Bob, K9BNR, Norm, WB9UBJ,

Dave, N9HF, and Bill, AG7V (SK).   They salvaged a tower from Walworth County.   A number of people dug the tower hole and poured the concrete.   Bob and Hap found a shack in Milton.   They put it on a trailer and pulled it down the back roads to the repeater location.

In August 2014, the Clinton 2 Meter Repeater received a new antenna.  It is mounted at 140 feet above the ground.   The tower work was done by Bryan, W9MUP, from Monroe, Wisconsin.  Check his data page on   The aluminum mounting bracket was constructed by WA9JLD, Lyndon.

The Gin Pole, a crucial tool, was provided by Conrad, W9DL.   A 440 MHz Repeater Antenna was also installed along with a Beacon Antenna for 220 MHz.  Other hams that assisted were:  Bob, K9BNR, Brett, K9BY, Chuck, WD9BB, and Greg, K9GJN.  

Clinton 2015 10:    New 443.175 antenna installed.  16 Bay, Folded Dipoles.

The Clinton repeater site is near Interstate 43 and Wisconsin Highway 140.

The Radio Shack for the Clinton Repeaters was renovated with new Siding, Dry Wall, etc, in 2016.

 Tower work by Bryan Waddell, W9MUP of Monroe, Wisconsin. 


Bryan has located a 10 Meter Beacon, on 28,295.8 KHz, W9MUP/B, on the Clinton Repeater tower.

Also at the Clinton location is a beacon on 222.058 MHz.  It has 5 Watts output to a Horizontal Loop antenna at the height of 100 Feet above ground level.   The call sign is N9HF.

Come join us, use the repeaters, and support (as you are able) the fund for maintaining the Rock County Repeaters.
