Variable Frequency Oscillators (VFOs)
5. Chapter 10, Harris ohm load. In Chapter 6 you were introduced to Chebyshev filters designed for 50 ohms. However, here we have no need for power, just voltage. Therefore, the filter is designed for 500 ohms, which is plenty of power for this application. Values are given for both a 80 meter VFO (3.5 to 4.0 MHz) or a 5 MHz VFO (5.0 to 5.5 MHz).
