Thanks for your help Dave! Yes. I was able to get 6 volts on R30 by turning L30. At first the voltage was too high so I adjusted the turns on T5 by spreading the red windings further apart. Then I was able to get to 6 volts.
I did a CAL FCTR with the probe on TP1 and the frequency set to 4000, The reading is 8912.22 73 Keith N8CEP On Mon, Jul 13, 2020 at 3:59 PM Dave Van Wallaghen <d...@w8fgu.com> wrote: > Hi Keith, > > Were you able to get 6v on R30 by tuning L30?
