Guest guest Posted June 21, 2011 Report Share Posted June 21, 2011 All: For those of you tired of judging kHz frequencies by sound alone, you can get a Grundig G8 from Radio Shack under 30-day return policy. It's not just a radio but it also has a signal level indicator for the kHz frequencies. Check monitors, keyboards, wires, dimmer switches, projectors, and all sorts of things, e.g., at 520 kHz frequency or other kHz frequency of your choice.
