Hi, I seem to have a problem with my new sBitx.
I was transmitting a time to tune my antenna and it just stopped. It was still receiving when I stopped keying and I feared I might have popped the PAs.
I have replaced the PAs but I must have done something as the PI will now not boot up. The Pi seems to be ok and will boot ok if I remove it from the sBitx and power it through USB-C but when plugged into the SBitx, the power light comes on and the disk activity comes on briefly and then goes out. Not activity there after. I have removed the PA devices altogether to see if that is the issue but still no boot.?
Does anyone have any ideas?
Voltages to the Pi look ok. The board is labelled V2.01. The docs/schematics on the HFSigs site are a little confusing I have around three different but similar schematics but they don¡¯t seem to correspond to my board?
