I'm pleased to announce I have escaped the noisy clutches of the City and bought myself a nice piece of land up the coast in a very quiet spot. Presently I'm only using my passive RX loop which has a single turn 'sense' loop for coupling into the main multi turn loop... When the RX is connected to an AC power power supply I get terrible AC growlers; however, put the RX on a battery and bang not a peep of nasty AC noise. I presume this is due to some coupling between the AC mains and the RX system and my isolation transformer doesn't seem to help so I wonder if someone could set me straight on what is going on here so I can solve the problem. Thanks for any support! 73 Scott VE7TIL
