I noticed in their catalog that the new MFJ-852 portable power line noise
meter can pinpoint faulty dimmers, electric fence arcs, sparking power
equipment, neon signs, etc. It's a sensitive (0.3uV) superhet AM
receiver with a noise field strength meter operating in the 135 MHz
region where activity is at a minimum and corona and arcing is far more
localized.
If anyone has one of these $99.95 units, I'm sure a report of its
usefulness would be of interest to all Topband Reflectorees, including
me.
