Hi, busy building a k2 and have following problem: - Alignment and test part II Performed this alignment (a.o. VCO alignment and VFO linearization), everthing went well, but: It turned out that that when tuning the frequency the tuning is very strange, no 10 Hz steps but rather erratic but after every 5-10 KHz it goes ok. Display gives the idea everything is ok (moves very smoothly) but when listening with a seperate receiver to the internal RX vfo it is not smooth. Measuring the PLL reference frequency Xtal VCXO: not smooth Measuring the PLL reference voltage out of the DAC: voltage is jumping ! Strange is when I perform the VFO linearization the DAC voltage is very smooth progressing and also the PLL reference is moving very smoothly. VFO linearization ends with "end" no error. Anybody an idea what is going wrong ? thanks, Carel, pc5m _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
