Don't feel bad Adrian, I missed it too, and I did a parts count, three
times. The first time I came up one short, but a second and third count
came out right. That's why it's always good to build one board before
ordering a bunch. But everybody is excited to build this neat little
transceiver. I hope that's all we missed. Jerry
