The adventure of amateur radio begins with Robert's Novice station in July of 1958.
Transmitting with a 75W crystal controlled cw transmitter on 40 meters, age 14 years.

My interest in RF amplifiers and antennas began at an early age.
This amplifier was a pair of 4-1000's in Grounded Grid for 40 meters that I built in 1963.
I'm grateful for the many mentors of that era willing to teach an enthusiastic 19 year old ham.
Leaping from 1958 to 2011, W7RR's snow covered QTH 25 miles (40 KM)
