Hi guys,


I am about to get back to my PPM toroid, it is wound and contains distilled water.


Somewhere I saw a chart of what approximate frequency to expect for different global locations, but I cannot find the site again.


Can anyone tell me what precession frequency to base my filter on at Latitude 34deg50min South, 20 deg east ?
