I've been grappling with this issue myself lately. Suppose one purchased
NN1G bare boards from FAR circuits, purchased/scrounged the parts and during
the course of construction (or maybe assembly would be a better term)
performed modifications to a greater or lesser degree. Does this qualify
as homebrew as opposed to assembling a kit from Dan's?
Probably not, one might be tempted to say. But suppose another individual
copied the NN1G circuit verbatim but built the rig using *ugly* construction.
Does this qualify as homebrew?
Does all of the circuitry in a rig have to be an *original* design (sorry for
the excessive use of astersisks and parenthetical statements) or does it
suffice that a rig be built from the available smorgasbord of mixers, vfos,
product detectors, etc. to permit one to call a rig 'homebrew'? I realize I'm
asking more questions than providing answers, but these are the issues as I
see them. This is the fine line we tread here.
My opinion lies somewhere in the middle. If I copied the NN1G or Ugly
Weekender and built it on whatever substrate and packaged it myself, I think
it should qualify as homebrew, even if the circuit design was not original
with me. If I purchased a complete kit from, say OHR, S&S or whomever, then
what I really did was assemble a kit, not homebrew a rig.
With so many good, 'standard' circuits available, it sometimes isn't worth
the effort to come up with an original design. Let's face it, we're not all
RF designers with 20 years of experience. Perhaps the deciding factor in
whether a rig is homebrew should depend on the amount of effort placed into
the sheet metal work and circuit mods. In that case, the NN1G rig I'm working
on could be considered homebrew.
Just some thought fodder...
