Some of the SARA Tech Committee along with a few other interested hams (notably Eric WD8KNL and Rick WB8UTW) have been continuing to pursue the noise interfering with 147.390 MHz. There has been a tremendous amount of hours put in by John N8CD doing direction-finding around the area. Thanks to John’s tireless effort the noise has been localized to the northwest edge of Wadsworth.
Just as we were going to proceed to contact the property owner, the noise vanished for over a week. This is always the best outcome. Unfortunately the noise has returned periodically. At the moment we’re tracking when and under what conditions it appears to see if there’s any commonality with weather, time of day, etc. If the noise stays around again, then we will resume working on a contact plan for the property owner.
Here’s the noise as recorded by WD8KNL.
