The disturbed ionospheric region produced by the Platteville heating transmitter facility was studied by the use of orbital and geostationary satellite signals. It was found that the modifier transmitter produces an ellipsoidal disturbed region with an e-folding radius of about 50 km. This region is centered at the height of maximum of the ionospheric layer and displaced about 30 km north of the transmitter. The disturbed region is made up of geomagnetic field-aligned irregularities, having e-folding radius normal to the magnetic field of 75 to 400 m the larger values are at night. They drift with the neutral wind with velocities of 8 to 25 ms. These disturbances cause scintillations as high as 25 percent in a VHF radio signal transmitted through it when the line of sight approaches the direction of the magnetic field.
