Well, had an interesting thing happen yesterday. I went to a garage sale and found a bunch of stuff-connectors, coax jumpers, plugs, and an interesting little "black box." Brought the treasures home and today I took the black box apart and lo and behold, on the bottom of the circuit board was written "Barry Kutner W2UP." What the heck is that Barry, a packet controller? No doc's came with it. 73 Tom W7WHY
