Hey folks, here is my setup: I have the SX28 with two ports connected in output mode to (2) mosfet push-pull driver subcircuits toggling 18 volts from ABOVE my LM2394 voltage regulator fed by 18 volts DC (1 amp). When I had one push-pull subcircuit, the set up worked fine. When I added # 2, the SX Key programs the chip then just before or at the beginning of running I get an error "Cannot find SX Key on com 3". I assume I am running out of power - is the SX "browing out"? What is happening and how to reconcile.
