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 not so stable. Maybe it is not so important to power supply voltage test. but I think it is very important to TCXO module. According to my test, TCXO is much sensitive to power supply voltage change (than temperature change). Any comments? 73 de BA4RF David On Tue, Dec 16, 2008 at 1:06 AM, wayne burdick <n...@elecraft.com> wrote: > Tom Whiteside (N5TW) wrote: > > I'm wondering if this new ADC reference calibration affects any other >> calibration settings.
