Re: [IRCA] The VACTROL progress

Steve Byan's original version Vactrol circuit used for Beverages can be adapted for Ewes.

The trick is that the Ewe element would need to be redone with a two-conductor wire such as lamp cord, twisted pair, or speaker wire.

You can't use Colin's box. Modifications would have to be made to it and to your transformer box. Perhaps the next version of Colin's box will have a bit of flexibility.
I'd scrap the EWE: it has by far the poorest antenna pattern in the EWE-Flag-Pennant-Delta (Kaz) group. Plus, it's ground dependence means a bit of change to the termination as seasons vary the soil characteristics.
Wet soil doesn't generate voltages all by itself. It might corrode things, but that's a different story.

Chuck and Colin,


So it looks like the best way is not to use this for the EWE the way it is designed? I may have to build a different antenna, one that is floating, a K9AY, a Flag, or a KAZ antenna? Any form of a "loop" is my best antenna to use? I was concerned about any form of voltage/current in the ground. Our soil is swampy and very wet most of the year. The grounding always enhances the TP reception here, so I like to use it. John Bryant and I always used to discuss that, as in OK it never made any difference.
My EWE's are all Ground connected. At the far end is a control (2-3K pot) that runs between a series of ground rods and the end of the EWE for termination. I peak the pot for a null and leave it.

There may be some current in the ground as the soil is so wet here and I live next to a swamp. I plan a new Western EWE at 20X115X20 in the backyard and I will be using the Vactrol there.

I cannot run a cable through the land over to the end of it because in the Winter often the wire would be under 2-3 feet of wire as it is a swampy cattle raising field. Now, I wonder if I could attach a wire to the EWE and follow the end down to the far end, getting the power to it? I could avoid running wire through the lake out there in the Winter, also the cows could not step on it. But would the extra power cable running next to the EWE affect the operation of it? Any thoughts from anyone
