One of the major players in the “top band” , or 160 meters is Bob Garrett, K3UL, who as a blind ham has never let his visual impairment get in the way of his ham radio hobby.  I first learned about Bob from an article where he was described as working on his own towers and antennas to build a first class HF ham station.  Bob is a friend and mentor to many hams, with an open door policy.  Just knock.  K3UL is my QSO Today.
