Hi Manuel, what exactly are you meant "doubts about IC1 and IC2" and "R6... pot seems not working right" ?

I`ve expected same reactions from my XYL and even more worst negative behavior to my purchases for this finances demanding hobby. After three decades of marriage, I discovered her real character and was really impressed. After each spendings on expensive equipment, she said only one thing: "let it be for your good health" and no one word of blame or criticism.
I`m jealous to my self :)

In Topic: Ameritron RCS-8V Remote Coax Switch

Hi all, I prefer one continuous coax per each antenna (all the way from the top, down to the shack) and any commutation do it in the shack. Couple reasons for this :
1. If antenna switch fails, its mutch easy to fix or replace the unit inside the house.
2. Continuity is preserved in an insulator (important for coaxial cable), so 50-ohm impedance stay unbroken (intact).
3. In worst scenario, when one coax fail, you still have others and better chance to finish the contest (also a opportunity to beat the Murphy's Law :) )
The best antenna switch commutate the braid too (stil looking for this).
Best regards and 73!
