Hi all: My computer does not see the radio at all while using the software from Elecraft. The software and input to the computer are good because it works on another K2 that I built. ( I don't have that one any more. Sent it home to its new owner.) Pin 7 of J1 should be 0 volts, I have 5.7 volts! The radio is not connected, so it's not coming from the RF board. Any ideas? 73 Alan W1HYV
