Dfc77 receiver amplifier
The complete schematic, and the C language source code is freely provided! DCF77 is the name of a german radio station on The time and date is coded into a 59 bit length frame, and is sent on the air through an antenna, by a 50 kilowatt power amplifier. A simple and tiny receiver can catch the signal, from approximately kilometers around the antenna.

Function and Comparison of Accuracy DCF77 and GPS Time Signal Receiver
The DCF77 transmitter is located in Germany Frankfurt and they are trying to receive the signal from a distance of more than km away. They did some interesting testing with different antenna sizes and posted their results online: "It seems that antenna selection affects received signal quality, bigger length and better tunning plays significant role in reception in long distances form DCF transmitter.
So if you plan to use a DCF receiver on long distances, look for a better antenna. Notify me when someone posts a comment here. You can log-in on forum link: Login page.

DCF77 signal receiver (MAS6180) with a ferrite antenna - version v2
The time signal receiver module comprises of a ferrite antenna and an AM receiver IC printed circuit board. The circuitry includes also an RC-filter for the supply voltage. The MASB1 AM receiver IC includes amplifier, demodulator and comparator blocks that transforms the received AM transmission into series of pulse width coded digital pulses which can be directly processed by an appropriate digital circuitry such as a micro controller unit MCU.

Circuit board for DCF77-SHO active antenna
LochMaster is a developers tool for stripboard projects. It has useful functions for designing, The Ic is wired as an astable and the frequency is constant and independent of the duty Because the CS bit-delta-sigma analog-to-digital converter lacks a start convert command, This circuit uses an 87C57 microcontroller and a few peripherals to condition X power-line
RF preamp DCF77 practical approach
After I have established one of the most noise tolerant software decoders for the DCF77 signal. I now focus on capturing a better signal, or even more important, a signal at all. Although my clock can deal with very poor signal noise ratios there must be at least some signal for it to do its work. Rothammels Antennenbuch. The conclusions are: a Bigger Antennas will result in better performance.
Building a DCF77 receiver
DCF77 is a German longwave time signal and standard- frequency radio station. It started service as a standard-frequency station on 1 January In June date and time information was added. The transmitter generates a nominal power of 50 kW, of which about 30 to 35 kW can be radiated via a T-antenna. With Media Broadcast GmbH, a temporal transmission availability of at least Most service interruptions are short-term disconnections of under two minutes.

Local time and date are programmed each minute by the RTC module, which has a battery to support its internal memory. Positive or negative output is possible. The best location for the GPS receiver is on the window ledge. In my office in the Ground floor it works too. Please allow 30 to 60 minutes for battery charging and time to acquire the GPS signal.
DCF77 Receiver Modules
Receiver modules are available through various vendors on the internet, a respective search pattern could be this one. In the LF bands there are a handful at least of stations available that provide a standardized time signal based on the time markers produced by high accuracy atomic clocks. In central Europe DCF77 is the a well known time signal station for radio controlled clocks and watches. DCF77 is intended for reception within a range of max. Ground wave propagation is possible within a radius of about km from Frankfurt, sky wave might reach up to between to km. But even greater distances occasionally have been reported.

Well, the following first example is not exactly an SDR, but at some time I will show how to transform it into a more flexible receiver. The target of this project is to design a flexible superherodyne receiver for full DCF77 reception including the phase-modulation. The receiver was built with just 7 transistors, lots of passive components, and one opamp.
In my opinion it is obvious. I would not wish to develop this theme.
