O teste é muito simples. Colocamos o diodo varicap nos terminais de prova, e depois sintonizamos a freqüência transmitida pelo oscilador numa rádio de FM. Se podemos sintonizar e logo variamos o regulador e se a freqüência captada começa a fugir, então podemos afirmar que o diodo varicap trabalha. P.S.: Very important is the varicap voltage. In the diagram that you posted the supply had 12V which is too high for this varicap. The maximum voltage for this model is 8V, so you have to use a stabilised supply made by either a zenner 8V2 or an IC 7808 and the minimum voltage should be about 1,2V.
