The LG Converter has an input filter consisting of L's and C's, an SA612 mixer (driven by a 10MHz crystal), and a coupling output transformer. The output frequencies (10 to 10.5 MHz) are close enough to the 10.7MHz IF for FM receivers that a standard IF transformer can be used.

Sound sample | PLAY SOUND The program of DCF77 may appear a little bit monotonic, but this program is immensely popular. DCF77 synchronizes clocks all over the continent. Once you get the beat, then suddenly it appears to skip one, and then... the minute hand of your watch moves. |
The package contains the PCB (holes already drilled in my case), all parts that must be soldered on it, and the description. Assembly is a true piece of cake and, if you don't forget to solder one connection (like I did), it will probably work right away.
