For some reason, I find that the pyrite detector is more sensitive and gives me much better volume than the diode. Also, with pyrite, you can eliminate the resistor across the crystal earplug.) sia townsvilleWebSep 27, 2024 · Do not connect the electrical power ground to your radio; they run parallel to the power cables and pick up all kinds of noise. Buried rebar and cold water pipes are FAR better.
