K2 Problem (serial No. 4159) Hello dear builders...I have a problem. At the 4 Mhz Oscillator calibration a problem occurred:
First the counter did not show 12090 +/- 30 KHz but: ~ 8.9 MHz I checked the board and discovered that I had made a mistake with D16; then I soldered D16 in the correct way and the measurement now is around 7,5 MHz (with built-in frequency counter) - verified all components and their polarity, all seems ok (yes - X1 is the 12,09 MHz oscillator) I verified the frequency of the oscillator with the help of my FT-1000MP and yes, around 7.562 KHZ you can hear the oscillation... by the way: the VCO Test is OK a friend who has successfully built a K2 thinks perhaps the 12.09 MHz oscillator is faulty... what do you think...so far the building was fun and successful...but now i do not know what to do.. THANK YOU VERY MUCH for your help Very 73 de Markus, DL9RCF No virus found in this outgoing message. Checked by AVG Free Edition.
