Oshkosh, WI!

The Federal Aviation Administration has advised us and the Green Bay FAA System Support Center (SSC) of an upcoming frequency change. Because both Wittman Airport (KOSH) and Green Bay (GRB) utilize 121.9 MHz for their ground control frequency, radio frequency interference reports have been noted at both facilities.

As a result, the Ground Control Frequency for Oshkosh will change from 121.9 MHz to 132.300 MHz beginning April 3, 2018.

A NOTAM will be issued to advise all pilots of this change.
