thanks for many thoughtful and useful posts here to this list. they certainly have helped me.
the 2 different PA's are alternatives (one of our local builders questioned the same thing). I have no clue why the designer left them there even in v5 -- but it does keep us on our toes. I haven't researched those caps -but I would imagine there is a place for them in the layout - for those making modifications.
As you know Farhan I trust stays quite busy - otherwise we would not be blessed to have a ubitx. What might seem small to us may not fit into his schedule.
Glad to journey with you. I hope to report when my ubitx gets measured it passes spurious, and I am toying with a couple of the AGC circuits (I now realize I may have installed them wrong - yes when the style of the schematic, that leaves off the off-board components confuses me!)
