Hi, I'm a bit of a newbie when it comes to HAM radio, and the K2 is the first serious electronic project that I've undertaken. I have now come to a point where I need to seek some advice from people who are more experienced than I.
I'm currently measuring the range between the high and low frequencies for the PLL Reference Oscillator. As the manual states, I should be getting a value between 9.8 and 15 kHz. However, my actual measured value is 8.94 kHz. I've done the previous step, 4MHz Oscillator Calibration, using an external frequency counter. I've adjusted C22 to have the internal frequency counter match the external one. Going on to the next step, I measured the High frequency range on the PLL Reference Oscillator and read a result of 12100.01 kHz, and a result of 12091.07 kHz for the low range. As I mentioned before, this is only a 8.94 kHz difference. I've also checked over some of the previous posts on this group, and have gone over some of the recommendations posted; specifically measuring the voltage across D16 and D17, which was about 7.75 V I'm at a loss now as to what else I should try, or whether I am able to move on and accept this value. Any suggestions or advice would be greatly appreciated. Thanks in advance, David - VA7DMS _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
