thatthere is one discharge per half cycle, or 1,000 sparks per second.(See Fig. 185.) Unless the antenna resistance is very high, there will usuallybe found with any quenched gap critical values of couplingbetween the primary and secondary of the oscillation trans-former. The antenna current will… … of these critical values of coupling. When the coupling is notadjusted at one of the critical values, the tone usually becomesrough and the wave becomes broad, or even shows two well-marked peaks on its resonance curve. By not properly adjust-ing quenched gap circuits it is quite possible to…
