FD 2010 effort at NU7B - class 1E battery from home.
FD2010 NU7B Class 1E Battery - using Elecraft K2/100 with KAT100 autotuner.
The better half of NU7B FD2010, Pam KC7TIZ.
Above is an old yellowed page out of the ARRL 1973 Handbook. This was my first transmitter, which I built several weeks before I got my Novice ticket at age 13 - the hook-up pencil tracings still on the schematic. The first power-up revealed a cold-solder joint on the HV rectifier. The second power-up was better. I was thrilled to see the light bulb dummy-load brighten and dim with RF energy as I adjusted the output match - a vivid demonstration of resonance.
It was crystal controlled - I had two 40 meter crystals and used this transmitter rock-bound for 18 months until I saved enough pennies for a used HW100 xcvr. Best DX with the 10-watt xmtr was Hawaii, from Dayton. Thanks to the great folks at the DARA club station W8BI, who gave morse code classes and exams long ago - I think they still give classes.
