Discrepancy Noted and Resolved

Locating RF Noise Sources: Theory and Practice
It was reported that local RF noise appears to be much greater than was observed in the Fall of 2022 before construction of the EmComm Center was begun. The noise is especially troublesome on the 2-meter band.
Stu Bingham gave a talk on how to locate sources of RF noise. You can hear the entire talk on the audio recording of this meeting.
After the meeting, Stu and several members walked through and around the American Legion building with Stu as he used a loop antenna to locate noise sources. Regina also took readings with a handheld device that measures RF field strength.
Both devices indicated the highest noise levels in the vicinity of a cash payout machine located on the first floor of the American Legion. It was also noted that a tobacco smoke filtering device was mounted to the ceiling in the same general area. It was speculated that this machine may cause RF emissions when it ionizes the air. It was also observed that the cash payout machine contains an uninterruptible power supply, and it was speculated that this may be a major source of the observed noise.
