I upgraded to a nextion 2.8 last night and its up and running properly. However, all I can hear now is a constant high pitched tone and loud squeaky scratchy sounds when tuning. Volume pot has no effect on volume. I've checked all my connections several times. If I lift the board off the standoffs it gets worse. I do have a good ground to the board.??If I unplug the nextion, the squeal goes away but receive is absolutely dead. I can barely hear the encoder ticks. Antenna is hookep up.??Any Ideas anyone?
