The 125 kHz signal for=20 downconverting is achieved by using a 1 MHz crystal oszillator, divided=20 by 8 by 2 CMOS 4013 stages... If the circuit is finished, i will publish it. But today it works very=20 fine! Yesterday the QRN was high on all grabbers (in DL) ;-) 73, Stefan PS: Nw hr qrt, going to France now!
