New Transmitter

Philip,

Good luck with the project.  Looks like you have a lot of work ahead.

So basically this tx is haunted by some guy they buried with a giant fro wig?

[ka4koe]

Yep.

[W2VW]

When you get the rig going it will be a treat to hear the signal up here.

Thanks for posting the pictures Fleep.

Haven't touched the Valiant all week. This trip really saturated my radio gland. Cleaned up the bottom chassis some last night. Wondering if I should hit it with a garden hose. My friends tell me this is a really clean one and obvious it was stored in a conditioned environment.

Big project. I may be at the point of running a power line in 2 or 3 weeks at the rate I'm going.

I also need to put some bumpers on those outriggers. Those suckers will kill your shins. You should see the bruise I already have!

Was busy today....

Better test that Pyramid cap.  Lucky if those things were good when new.

Notice the ripple freq on the GE filter reactor, 360 hrz, rectified 3 phase.  Wonder how well it will work at 120 hrz.

Fred

[ka4koe]

They were using that piece of iron when taken out of service. Elaborate please.

[KA2DZT]

10hy choke at 360 hrz is still a 10hy choke at 120 hrz.  The inductive reactance would be less at 120 hrz.  The higher ripple freq from a 3 phase supply is just easier to filter.  Was that xmtr running on 3 phase power or just single phase??  The building it was in probably had 3 phase but the xmtr may have been on one phase.  Is the plate xfmr 3 phase or single phase??

I wouldn't worry about the choke, just use it as it was being used.  You may need to add more capacitance in the filters.

That's a BC-1T. It's single phase.

And that's a coil not an inductor. Inductance only exists when there is current.

Unless I'm confused, a coil is also called an inductor

I'm assuming it will have some current running through it when he uses it.

[Steve - K4HX]

Just yanking your chain. But it is improper use of terminology that has become standard. There is no inductance without current. In that photo, there was no current. Speaking of current, I often hear people speak about "current flow." Current doesn't flow. 

[ka4koe]

Current is, if I'm not mistaken, the movement of electrons in a conductor from (-) to (+) as the result of a difference of voltage potential,  i.e. free valence electrons moving from atom to atom (3 or less in outer shell for a conductor). 1 coulomb of electrons (a big number) moving past a point per second is 1 ampere. So perhaps flow is a misnomer but used all the time to visualize the process. Of course, the electron holes move from (+) to (-).

[KA2DZT]

Thanks Steve,  you had me going back to re-read some of this stuff along with all that math that I long since forgot.

Fred

Current flow? All very mysterious, using electron exchange among creatures inhabiting Bohr's atomic model as an approximation.

All will become clear once we've cracked the quantum world's "sound barrier," that which lies beneath the Plank realm.  This may never occur since those exceedingly small dimensions approach absurdity. In other words, our limited laws descriptively break down at that which we can only surmise.

One thing we do know in the macro world is that it takes work to establish a voltage difference. We know you can't get something for nothing in any real, measurable time interval... But for very short periods you can fool the measurers, be they glass, metal or human, hence negative vibe promotional theory which we've all experienced especially on Christmas morn as children and daily in the political promise realm as "adults."
The promise of that "Red Ryder" far exceeds the reality.

Did that electron really flow? Did its passing destructively produce heat in impeding material?  Was that heat a photon?  How did that electron excite the material to produce the photon? ...and just what is that photon, wave or particle or both?
Got the breakfast call, gotta go.

[ka4koe]

I prefer the "Row Row Row your Boat" explanation.....Life is but a dream anyway.

[W9ZSL]

The power requirements for the BC-1T are 230 volts, 3 wire, solid neutral, single phase, 50 or 60 cycles.  Approx 4,000 watts consumed at 100% modulation at 1KC.  Since our station had 240 volts, the xtr had provision for a "variac" to drop the voltage.

[ka4koe]

Straight out of the manual.

[W2VW]

It's not really a manual until someone reads it.

[KD6VXI]

They always looked like a book to me.

Manuel was the guy turns no wrenches.   He was performing manual labor.

Lol

"if you're living right, throw the HV plate contactor switch."

Love the Gates BC1T manual/book/pamphlet/religious tract. It's full of humor.
