Halil, The QMX is trying to start, VDD comes on when you press the button and the processor starts. Check whether this VDD (3.3 volts) reaches the MS5351. Both sides of L201 should show 3.3 volts,

I also recommend staying away from that Chinese solder. It is too thick. Thinner sized solder works better. Ed AB8DF

Hi Warren, I get this error every time I turn it on and the device turns itself off after this error message.

There is no smoke now. However, I saw the first smoke at the bottom of the BNC socket but I couldn't see exactly where it was coming from. I think we need to focus on this area as well.

I used generic TO220 style linear regulators for my linear SMPS replacement, had to trim the tabs a bit but they are rated for 1A and while they get warm seem OK. As Jerry says the ADC_* lines need to

It looks as if it failed initialising the Si5351, as the message says.? This is actually a MS5351M, IC204, does it look burnt or is it hot? IC201, an EEPROM array uses the same I2C control so a
