Hi Geoff,
I agree.
Hmm puzzling, unless the analogue input have all died suddenly. A bit strange.
Ok, A4 and A5 are the I2C lines, when you connect an antenna to the rig, do you get extra noise with the volume up.?
If you don't it means that the I2C bus is not working and the si5351? does not get programmed.?
Is that the case?
