About Ronja Hertz

Ronja Hertz is a frequency generator suitable for testing Ronja 10M Transmitter. It generates 1, 5, 10 or 20MHz square signal.


On the top of the device there is a four terminal wire nut. Two right most wires (signed "+12V" and "GND" are connected to power supply. Two other wires (signed "OUT" and "GND") are connected directly to any Ronja 10M transmitter.

Frequency is selected with two switches.
