Circuit board for DCF77-Receiver with Signal level meter
DCF77 receiver for receiving the time signal at 77.5KHz.
PCB 160 mm x 54 mm x 1.6 mm.
It is possible to install the receiver in a tinplate housing.
The signal evaluation can be separated or left as it is.
The circuit runs with a stabilized supply voltage of + 12V. All other tensions
are generated internally. The time signal has an output voltage of + 5V.
The field strength of the receiver is shown with the LA2284A and has advantages in the alignment
the active antenna (Article No. 001701).
The red LED (D16) indicates the time pulse.
Detailed building instructions will come soon. Circuit diagram, assembly diagram and parts list are already available here.
All electronic components (except 4.7nF C5, C8, THT variant) are available in our shop.
The resonant circuit capacitors 4.7nF are available for the SMD variant.
The two coils are available as a set of coils with a fully wound coil (L1 and L2).
