Marlo Montanaro - KA2IRQ
No thunderstorms/lightning for several months (summer).
The connections all seem good- weird thing is I fired everything up this morning and it's working like a charm now (knock wood). However, the supplied cable with the Piexx serial board (in the radio) has a very long cable- was thinking of replacing it with a shorter ribbon cable. If the Piexx board is going, a replacement is $100. May pick one up just to have a spare- expensive spare.
This is a serial interface card in the computer, so no USB involved. I'll see if I can pick up a DB9 to USB converter and maybe switch over to USB.
I'll have to try the loopback test.
