I am building my K2 (#2730) On the 4MHz Oscillator Calibration, the first 3 steps is to connect the P6 (control board)with TP3. In my case the frequency counter show about 500 kHz instead of 12,090 kHz +/- 30kHz. Can anybody advise me what is seems to be the problems and how to troubleshoot this? Thanks in advance. 73 Roy / N6FUN
