I made a short video of the 50L6 transmitter operating and some in the dark footage as well with the tube glowing and my RF indicator bulb and loop blinking away to the CW. Tomorrow I will draw out the circuit so I have it on hand. I am adding a cap circuit to rubber the crystal. I tried a quickie set up and it worked well. I am still torn between fixed caps and a switch or a 100 variable. It gives me enuf flexiblilty to be able to QSY to avoid others in QSO.
I may also give it a 40 meter tank circuit and work the harmonic for two band operation. I have a double gang cap and could wire the 40 meter coil which I made BTW when I made this set a few years back. The 80 meter left as is and the forty meter hooked to the unused cap section and switch between the two. I will try it on a dummy load first to make sure it works. Other pics in the video are my regen set and my 40 meter single tube TNT TX
I found the original site where I got the circuit years ago. It is too bad more dont build them because it sure works well and uses very very few parts. http://www.qsl.net/wd4nka/IMAGES/50c5tx.gif. Anyway i said I would make a diagrahm but I found the original which is even better. it works for a 50c5 or a 50l6 depending on the vintage. They are found in the AC Dc radios we grew up with and can be had for nothing. When you stop and think you could build a complete good working reasonable power transmitter from stuff you might find in the dump, even the TV crystal, tis amazing. No it isnt a double yoked PLL mega power transmitter but it does work and it works well. I like to build vintage stuff. it is for me fun
