Electric Fence cause interference

[granners]

I have put a couple of posts up about interference I am getting. Well
, I have located the problem , my neighbours electric fence. Although
I am overjoyed to have identified the problem (it has been bugging me
for months) how can I overcome it. shot the dog ? haha I believe the
fence is sending out some kind of pulse in to the airwaves and when I
am recording electric guitar I pick this up. Apart from turn the fence
off , is there anything I can do in my room to stop this ? relocating
the unit and re-earthing it has not worked. It is definately sending
out something in the air as I have checked all my earthing and
electrics.

Any help much appreciated.

I'm sorry, I've got to say it.

Don't wizz on the electric fence.

Electromagnetic radiation being what it is, there's no doubt that every
electric fence in the world puts out electromagnetic radiation when it
operates. Most of them don't block out the neighbor's electric guitar.

The fault is with the electric guitar and its amplifier being too sensitive
and/or there's aproblem with the electric fence putting out too much of the
wrong kind of electromagnetic radiation.

I recommend that you search google newsgroups and the web to find other
people's past experience with electric guitar and electrical interference.
What works for lots of things will probably work for your specific case.

In the USA there are laws governing the acceptable level of spurious
emissions from electronic equipment, including electric fences I presume.
That may be the case in other countries, too. I would start by contacting
the manufacturer of the electric fence equipment, describe the problem, and
seek their assistance in finding a solution.

Eliminating the problem at your equipment can be difficult. If it is
entering your equipment through the mains, filtering may be effective. If
it is energy radiated from the fence that is affecting your equipment, you
may have a long process of 'cut and try' filtering at the input stages
(typically) of your audio equipment. Suspect the higher impedence circuits
first.

Where's Scott? He's probably designed an electric fence circuit or two in
his mysterious past. I've only installed them and been bit by them as a wee
youth on the farm.

Hi John,

When I was putting in dedicated mains I borrowed a mains 'sniffer' to listen
to all the noise coming in on the distro board. Sure enough there was a
regular ticking noise that I found was interference from an electric fence a
quarter mile distant coming in through the mains. Chat to the owner, some
solid state EF units don't radiate quite so much as the old ones I heard.
Try mains filtering to see if it helps as it may not be all airborne.

Electric fences have a very distinct sound because they buzz on and off
with a duty cycle of a second or so.

The first thing to do is make sure all the fence insulators are clean, and
use decent ceramic insulators and not that plastic crap. Current leaking
through the insulators arcs over, and that makes RF noise. If it's a big
system with a lot of cows or something, it can be a real problem keeping
everything clean and keeping the grass from growing up over the lines and
arcing over, too. If it's just for a dog it shouldn't be a big deal to
keep the system maintained right.

You can probably ask the neighbor to turn it off while you're working. As
long as the dog never knows when the fence is on and when it's off, it should
be effective even when it's shut down.

So you have to make sure you don't play your guitar loud enough for the
dog to hear.

having just put up 3 acres of electric fence myself, and worrying
about the effect on my recording setup, i can say all is fine. but i
learned a few things....

after reading the literature on fencing from many different fencer
manufacturers, one thread is consistent.... grounding. electric
fences MUST have a superb ground. i personally put in 3 - 8 foot
ground rods sunk into damp soil for my fence ground. this is not
extreme but the minimum. all literature stresses the importance of
this for RF interference reduction. start there with your neighbor
and offer to help him install them. you both might win as he'll get a
better fence and you'll get RF reduction.
