Thanks to K8IA and KR6X for correcting my
mistaken assumption that I was the first to use SO2R
consistently in DX contests.
I was the first to do MODERN SO2R then. :-)
I find it interesting to note that when I actively did
SO2R in DX contests starting in the early 80's, no one else in the
perennial top ten was doing it. Some had a radio and amp
on each band, but they were not operating SO2R.
If it had been such a helpful and interesting strategy previously
used by W4KFC, W9IOP, KR6X, and others, why was it
abandoned in DX contests? Does anyone know?
