Can anyone tell me how to make my VCR stop flashing 12:00? It's really annoying.

Congrats, Macy See Profile.
Plug it into a 220V outlet?
Or, you could turn the hyperpower station onto a 540 gigacoms and put the tranobox to an infinity delpise.

This looks like a good place to give a sort of intro since this is a forum I stop by on a regular basis.

As for me I started playing with electronics when I was still in the single digits of age. By 15 I actually had a job as a "studio engineer" at a 1 KW radio station. Since then, I've continued on in the field and do broadcast radio engineering and all sorts of industrial electronics. This is my 30th year, of doing radio.
Certs include,
FCC, General Radio telephone, Ham Technician
SBE, Senior Radio Engineer
Hammond Organ Co, Technician
State of Florida , Firefighter, Paramedic, and Fire Officer 1 (that's what I do for fun )

There's more but that's enough to get the idea.

Dr Jim,
Just curious isn't it a bit cramped living inside an ATU (Antenna Tuning Unit) Not to mention the RF bites when you move the wrong way.

Couple of questions if I might.

The device at the top left to what looks like a spark-gap is that isolation for tower light power? Is the antenna cap fed aka un-grounded?

Is that a flux capacitor that I see in that ATU?!?

Yes, that is a lighting choke (Very Hi Z at AM RF frequencies) and the tower is insulated from ground and fed through the cap. The Lighting choke allows the 110V (neutral & 2 hot's one flashing and one steady) to cross the base insulator with minimal change in base Z, & radiation. That is an arc gap to give lightning someplace else to go rather than through the cap and other circuits, which it can and WILL do.

As for the Flux cap... you're close, it's a vacuum variable (read very expensive) capacitor.
