I personally think it's unlikely that even if someone is trapped by
the fancy-pants autotuner they bought, that they probably don't need
an extra fifty feet of line to deal with it. In my experience even ten
extra feet of line at 80M can noticeably change the matching taps I
use on my tuner if you're working in the 1/4 WL 65 foot feedline
range. Of course that extra ten feet might make their fancy pants
autotuner crap out on 20M, etc. and I can see how someone might start
feeling like the old lady that swallowed the fly. I would rewrite the
song to "swallowed the autotuner".


Wow, you do not like autotuners, eh?

I use both regular and autotuners, and both work pretty well for me.


Neither wear pants, fancy or otherwise 8^)
