In my trip on I-94 from Minnesota to Milwaukee I drove past 5 construction update signs running KA band. 3 were running 34.7 from New Richmond to the Dells and 2 were running 35.5 in Jefferson County between Madison and Milwaukee

In other notes there were 6 troopers driving towards me on I-94 running short bursts of instant K band. Watch out on Wisconsin there patrolling heavily
