As a novice reading "Build Your Own Transistor Radios" by Ronald Quan I was kind of mystified by the author's statement that using "vector" board would be easier than using prototype boards, but the easiest is to use copper clad.
I could understand why you do not want to use prototype boards, since they have a lot of stray capacitance and I heard you do not want to use them for radio projects.
On the other hand I could not understand how copper clad could be easier, since I assume he meant I would need to etch and drill the board, which did not seem easy at all.
Then, I found on the web pictures of the author's own versions of the projects he did for the book. Here is a clip:
I do not get how this works. Do you just solder leads right to the board? In that case, isn't everything just shorting out? Also, when I try to solder stuff like this (big metal slabs) it soaks up so much heat I cannot get the solder to melt.
I assume the sea of copper has some kind of electrical shielding benefit, but do not know what that is.
