LNB bias T with onboard reference TCXO PCB
Re: LNB bias T with onboard reference TCXO PCB
To note:
C3 on the PCB is not fitted,so don't go looking for it in the parts list, on the floor or forum. It's there in case it is needed for tuning the crystal filter. It turned out not to be needed with the specified crystals. Select on test if you feel so inclined.
