SECTION EIGHT
ACKNOWLEDGEMENTS
I would like to express my sincere gratitude to the hams and friends who provided me guidance and encouragement. This is my first home brew AM transmitter build, so I figured I might as well go big. A lot of experimenting was done and a lot was learned. Every section was thoroughly rebuilt or modified and tested before proceeding to the next phase of the project. The transmitter took about nine months to build.
Kind regards, KB7OCY Henry Hurrass
W7GNP, Jim Wortham, for providing me with the 1950’s home brew “parts” transmitter that I used for this project. The original intent was to refurbish the old transmitter, but it was too far gone.
KE7TRP, Clark Turner, for his patient mentoring on the 304TL audio stages, bias settings and the like. These are things you just can’t seem to find in the handbooks.
K7EWE, Jim Wiggins, for the brand new old stock 304TL’s sockets, encouragement and friendship!
K6SAI, William Orr (SK), author RADIO HANDBOOK, a fantastic source for reference material; in particular, the PI-L network and High Power RF Tetrode theory.
