10 Khz Transmitter

[Clocker]

Is it possible to build a 10khz radio transmitter? The required range
is only about 100 feet.

I have one of those electronic fences and I believe the collar works
on a 10khz frequency. My dog has an extreme barking problem and I
want to use the collar to train him not to bark. So, I thought I
could have some type of transmitter than I can use to briefly activate
his collar when he's barking too much so that he learns that barking
the way he does is unacceptible.

Is it possible to build a 10 khz transmitter to do what I want? If
so, where can I find some info on how to do it? Or, is there
something I can buy that will do what I want out of the box?

Thanks,
Clocker

Hi Clocker,

You can buy these for around $100 from various manufacturers. Most work
on 27MHz. I could dig out the manual of ours if you need the brand. They
often have a "good tone" (a buzz) if the dog behaves or stops a bad
behavior on command and a bad tone (beep) if not. Then there are several
pulse amplitudes for the shock. Be careful, try to stay with the low
amplitudes where the dog just feels it. It should never yelp. Then it
would be too hurtful. With our female dog all it now takes is to show
her the remote. Even if she doesn't wear the collar...

Just one word of caution: Never leave this collar on the dog unattended.
If for some reason it goes on the fritz and rapid fires the dog can
suffer serious burns. That has happened.

Oh, BTW, there is no way you can transmit on 10KHz far enough with a
tiny remote,

Regards, Joerg

Funny... I was at Wal-Mart today looking at anti-bark collars for the sister
in-laws CRAZY barking dog, and the ones that they had were 44 dollars, and
said that they only gave a mild tingle, not a full-out shock. They were
adjustable, to trigger if your dog barked either a little, or a lot.

One manufacturer is Tritronics in Tucson AZ. Really nice guys.

Designing the transmitter is easy. Designing a small antenna for 10 KHz
is nearly impossible.

The wavelength is C / f, where C is the speed of light, and f is the
frequency. In your case it is (300 * 10^6) / (10 * 10^3) = 30 * 10 ^3
meters or 30 km.

My sister had a dog with a barking problem, and she chose a surgical
solution instead. She resorted to this only because she thought the scary
neighbors might shoot or otherwise harm the dog if it continued to bark.
The dog doesn't seem to know or care that her bark is now relatively
inaudible. She still goes through the motions happily.

What is prompting the dog to bark in the first place?

Not under these conditions, because your receiver would be inside the
tank coil. Dr. Tesla tried this trick, but Edison wanted DC.

Various things: a squirrel in a tree, a bird on a fence, a skunk in a
bush, some new person appearing for the first time or an old friend
coming back for another visit.

She does not growl or bark in aggression. It is just a way of getting
attention, as far as I know. You'd have to ask my sister if you want more
details. ;-)

Thanks everybody for your feedback thus far. I really appreciate it!

Joerg- If you don't mind digging up the brand name, I'd appreciate it!

Also, I have one point of confusion as well. If the collar responds
to a 10khz signal like I believe it does, how will a transmitter that
works at 27Mhz talk to it? I'm sure my lack of knowledge re:
electronics and RF is definitely coming through here so please bear
with me.

Thanks,

The correct solution is to train the dog's owner.

As usual, he's looking for a mechanical solution to mask the actual
underlying human problem.

Oh, it's been quite evident since the original post that you're pretty
much clue-free.

Please don't punish the dog for the irresponsibility of her master.

With my wife not being here I couldn't find it. Of course...

But I found it back on the web. It is an "Innotek SD-100" and we got it
at a much lower price a couple years ago. I did a web search back then
and found a great deal, something just above $100 or so. Works great and
the band can be adjusted to nearly any size dog. It is not fully
waterproof though so don't use it on a Labrador that likes to do some
laps in the pool. But at least there are O-rings for the battery
compartment so a slight drizzle during a walk probably won't matter
much. The batteries are a bit odd but can be bought at larger
supermarkets. Here is the link to check it out:

http://www.innotek.net/store/produc..._id=4&osCsid=bd49beed5c9f014fda1d848c407f6f60

This product doesn't always reach around the house since we have
aluminum backed insulation in the walls. The Dogtra and Tritronics
brands we tried from friends could reach farther but the bulky rubber
antenna was getting in the way, especially on walks.

27 Mhz carrier using AM modulation of a 10K signal ?
or even a FM for that matter.

Good point, there are special implants available for dog owners. A
tiny microchip gets inserted into the owners brain, providing the brain
is big enough to store the chip.

When the dog barks, the chip transmits a message to the owner,
causing the owner to bark in response. The result is both dog and
owner get arrested and impounded for causing a public nuisance.

Check your local friendly pet shop for more info.

That INNOTEK thing looks like it's an additional collar my dog would
have to wear. I don't want to buy an additional collar, I want to use
the existing one he's already wearing for the invisible fence.

I want to be able to activate the collar he's wearing for the
invisible fence on demand. Is that possible given that the collar
works in response to the 10Khz signal?

Thanks,
Clocker

Such a pity to burden the poor animal with another collar. Why don't you
wear it?
