Output power (including harmonics): A few mW up to 15W (depended on transistor, crystals and voltage/current used) at 50 ohm. 2. It can drive any antenna directly, 50 ohm or higher impedance, without external tuners. 3. Bands of operation: Currently 40m, 30m. 4.Antenna tuner prototype - version 'A'. However, since I intend to use my homebrew antenna tuner on the lower frequency bands (160M to 40M) I arbitrarily chose a maximum inductance of around 17-20 µH - assuming that more inductance would allow me to use variable capacitors having only a maximum of 470 pf per section on the lower ham radio bands.How the AM Radio Circuit Works. When the reactance (AC resistance) of capacitor C2 is the same as the reactance of the coil L1, resonance occurs at the frequency f=1/2π√ (LC). For example, with L1 equal to 300 uH and C2 equal to 100 pF: F = 1/2π√ ( (0.0003 H)* (0.000000000001 F)) = 919kHz. If they are in parallel (as in our circuit), the ...
