The power supply for this radio is a 175 watt inverter powered from a 12 volt battery, which in turn is charged by a set of solar panels, the charge from which is regulated by a Morningstar Sunsaver charge controller. If I unplug the radio from the inverter and plug into the regular power supply from the grid, the noisy signal becomes clear. Additionally, after I unplug from the inverter, for a second or so as the fields in the system die down the signal becomes clear before the radio stops working. This seems to indicate that the antenna is ok, and that the interference is in the solar system somewhere, but not the inverter (otherwise the night time reception would be bad) but perhaps the charge controller is having an effect on the Trisonic amplifier? I'm guessing that the inverter or charge controller are throwing out RF noise that's interfering. Since it's "heliotropic," maybe the latter. Have you tried unplugging the solar cell from the charge controller during the day and seeing if it clears up? If not, give it a go and see what you learn... |
