It's a near miracle they finally got the permission to go. And then it cost an actual fortune to fund, even though it was relatively close. For the value that QSL represents, it's cheap at many times

I really don't understand the debate. The universe moves on and that includes ham radio. We can't rewind the clock - even if we could although I just bought a SX-101 so I could get the old feeling I

Thank you Frank. 1000' - wow. What is the topology of the fanout (single antenna to 6 op positions); do you hang a MC splitter or similar off the back of the K8ZOA preamps? I have looked at the K9AY
