Hello eveyone, I am getting back to troubleshooting the problem I am having with my K2 The "4 MHz Oscillator Calibration" step 3 on page 60 states "the counter should show a frequency of 12090 kHz +/- 30 kHz". Mine reads 12600. I have cheked the soldering a number of times and had a friend check the soldering. We were unable to find any bad solder joints. I showed the schematic to another ham and he suggested the following: 1. Check turns on RFC14. Turns = 10 2. Measure voltage at RP2 pin 2. Measured 7.7 vdc 3. Measure frequency with R19 removed from circuit. This will remove the thermistor circuit and measure the native frequency of the crystal. My question is, before I remove R19 does this logic sound good? I also measured the resistance of each pin on the thermistor board while it is install on the RF board and got the following readings. Would someone be able to verify these. pin ---> pin ohms 1 ---> 2 1.79k 1 ---> 3 1.79k 1 ---> 4 3.7k 1 ---> 5 3.7k 1 ---> 6 8.7k 1 ---> 7 8.7k 1 ---> 8 3.9k 2 ---> 3 short 2 ---> 4 1.9k 2 ---> 5 1.9k 2 ---> 6 6,9k 2 ---> 7 6,9k 2 ---> 8 2.2k 3 ---> 4 1.9k 3 ---> 5 1,9k 3 ---> 6 6,9k 3 ---> 7 4,9k 3 ---> 8 2.2k 4 ---> 5 short 4 ---> 6 4,9k 4 ---> 7 4,9k 4 ---> 8 290 5 ---> 6 4,9k 5 ---> 7 4,9k 5 ---> 8 290 6 ---> 7 short 6 ---> 8 4,9k 7 ---> 8 4,9k Thank you everyone for your help Terry VA6MAC
