I just read the topic that his message originally was meant for.? I have a learning question.? What do the jumpers at W0-W1 and W2-W3 physically do on the board?
I am currently using the U3S successfully with LPF at position 0.? I have the relay board all set and ready to go with (5) LPF.? I am missing the relay to put in position 0.
I was considering continuing the final wiring of antenna while I waited on the final relay.??
