Re: [Elecraft] Re: K3: ADC Ref calibration

My DMM say only 4.93v on pin 2 of the ACC connector. After calibration, supply voltage measure show me 13.7V, actually it should be 13.85v(test on K3 PS connector). During the 100w key down test, K3 shows 13.1~13.2v, but actually it should be 13.81V. I use DAIWA 32A PS So, I think 5V standard is

[Elecraft] Re: K3: ADC Ref calibration

Hi Tom, At present only the PLL voltage and supply voltage measurements are affected by the ADC REF calibration. You shouldn't have to re-do any other calibration steps. 73, Wayne N6KR Thanks Wayne, What prompted the question was getting a PLL error when using the sub receiver during the
