Thanks for those recordings, Sealord.  I've been seeing logs for the past week from folks noting that buzz, but for some reason it was barely audible here.  I was able to hear a little of it under KARR's recent broadcast, but otherwise nil.  Might be my reconfigured fugloop - I recently modified it to more effectively null out noisy parking lot/street lights - but I'm surprised it's also effectively nulling out this ute QRM.
