R68 Y ap ajiste yon fwa eksitasyon an se konplè. Pou kounye a, jis mete l 'nan sou seri mitan, ki pral ba sou 1V nan pwodiksyon an. Si ou deja gen mèt ou a pou mesure nan devyasyon (nenpòt ki mèt panèl soti nan 10uA 1mA plen echèl ta dwe travay), ou ka trase yon echèl pou li epi ajiste R73 konsa ke li li 100% devyasyon (oswa 75kHz, tou sa ou pito). Èske sa a ak yon siyal ki gen plis pase 1V aplike nan entrain yo, se konsa ke se siyal la ke yo te limite. By wout la, lekti a yo ta dwe menm bagay la tou kèlkeswa si ou aplike siyal la odyo nan yon sèl entrain, oswa yo tou de. Lè pa gen opinyon odyo, mèt la ta dwe li sou 10% nan valè a devyasyon plen. Sa a se ton an pilòt, epi ou ta ka vle yo ki make nivo li yo sou kontè-a.

R68 will be adjusted once the exciter is complete. For now, just set it to about mid range, which will give about 1V at the output. If you already have your meter for the deviation metering (any panel meter from 10uA to 1mA full scale should work), you can draw a scale for it and adjust R73 so that it reads 100% deviation (or 75kHz, whatever you prefer). Do this with a signal of more than 1V applied to the inputs, so that the signal is being limited. By the way, the reading should be the same regardless of whether you apply the audio signal to only one inputs, or to both. When there is no audio input, the meter should read about 10% of the full deviation value. This is the pilot tone, and you might want to mark its level on the meter.
