I've noticed something for years and just wonder if anyone else has the same
experience? This morning I was copying
OH6AH on 40M LP but he was pretty weak and the background noise made it a
little difficult. The speaker was on and
I needed to go downstairs to get something - as I descended the stairs it
seemed like a filter was switched in by my
brain and all the background noise went away leaving only the signal. Just
like a nifty audio filter. In years gone by
I have noticed this many times but never asked anyone about the phenomenon. In
Arizona I would be working in the
yard maybe 100' away from the shack, the window would be open and radio on and
I could copy weak signals without
any problem.
