From Chris, KD4PBJ:
This is my AM band regen I built during December and early January.
It uses a 955 acorn tube and is a really hot performer! I can pick up dozens of stations with only a 20 ft piece of wire thrown out my shop window and tied to a nearby tree limb 5 ft off the ground. This is from rural Tennessee where we have no local AM’s.
It uses a velvet vernier I bought off eBay back around 1999 or 2000 and had saved for a special project like this.
I’m running filaments off a 6V lantern battery and plates off a type 415 45V battery.
A nice ham/machinist I met on the Time Nuts list who lives in San Francisco made my insulated shaft couplings. I got the Delrin rod cheap off eBay. He cut them to length, center drilled for 1/4 inch and drilled each end for 2 setscrews.
Fabulous project, Chris. I'll need to make a one hour road trip to see it and hear it.
ReplyDeleteI got that same vernier from a 1938 Eilen Radio Laboratories All-Electric 3
