Licenced for any ship, any sea, a well qualified, intelligent amateur radio operator designed, built and refined a ssb transmitter around 1950 utilizing an LM-16 frequency standard as the VFO. The LM-16 was the Navy variant of the BC-221 frequency "meter" that allowed transmitters and receivers of ships and planes of WWII to be SET to the correct operational frequency with minimal real time tuning. This relative of mine published in QST his sideband transmitter with one mistake in the schematic, ON PURPOSE. I was 10 or 11 at the time and asked why he put a mistake in the plans. He said, "That mistake will be recognised by hams who know what they are doing, they will correct it and build a good transmitter. The hams that are ignorant will never figure it out." This was before I learned to ask, "Why is that important to you?" I thought at the time that his action was pretty mean, petty and arrogant. But what did I know. I was just a kid. Asking questions. Now, I am an old man. Still asking questions! Maybe some of you old guys met someone like this but he was the only one I ever met like that in ham radio. Every one I have ever met, except him, would bust a gut to help another ham or some kid who was fascinated by ham activity. The guys at Huntsville Hamfest and Ozarkcon bend over backwards to help each other, friend or stranger. There are plenty of genius designers and builders these days. Elecraft, M0NKA(SDR radio), QRP kit builders(many) just to scratch the surface. Any mistakes in this stuff are honest ones! My distant cousin was a very accomplished professional merchant Captain and a genius in every sense of the word but with a huge character flaw. He has been Silent Key for a couple of decades and I think ham radio is better without him.
