Of course, I could (probably am) wrong on this occasion. -- pyotr filipivich. as an explaination for the decline in the US's tech edge, James Niccol wrote "It used to be that the USA was pretty good at producing stuff teenaged boys could lose a finger or two playing with." |

The 22-250 is certainly one of my most used guns as is my .223. I just love the 22-250 for varmit catagory, into why coyotes fall.

Larry, if you figure out a solution to that problem, let me know. I have the exact same problem behind me. Hartmann whistle and a TV satellite dish. A Hartmann whistle can produce extremely intense ultrasound -- 150 dB or so. 120 dB is threshold of pain for humans. 150 dB is 1000 times the sound power of 120 dB. A Hartmann whistle runs on compressed air, can be easily made with a lathe and perhaps a couple of silverbrazed joints. Instant canine headache at ranges probably as far as a barking dog would be bothersome. The wavelength of 22 KHz ultrasound is slightly shorter than Ka band microwave, so beamwidth (and gain) will be even better with ultrasound than it is with microwave from Ka band satellites. Beamwidth would be about 1 degree half power included angle, , which is an "illuminated region" of about 42" dia at 200 ft. The trick would be to discover where the device points, and then put a sight on it for aiming at an actual target. A piezo tweeter makes a pretty good ultrasound microphone for testing. I have started to build one of these twice. The offending dog moved away both times before I completed it. I still have the dish, though. |

Don, I'm not quite grasping what you intend.
Do you mount the Hartman whistle at the focal point of the dish, or do you run it through a microphone/amp/tweeter? For that matter, why not mount the whistle at near the offending fenceline, connected, with a remote-actuated air valve?. Could be a pull-wire, or some sort of R/C item. That would also probably affect the noisy teenagers at 2:00 AM on worknights. At least the girls would leave, and the boys would leave shortly after Don Foreman wrote: On Fri, 12 May 2006 09:46:38 -0500, Rex B wrote: Larry Jaques wrote: Wait until the coyotes take out the pets, _then_ shoot them.

We had this issue come up in our neighborhood recently. We're in a suburban community which happens to not be in city limits (thank God). Coyotes have been coming into backyards and making a racket, probably thinning the cat population. At a neighborhood association meeting we asked the sheriff's deputy attending, for advice. "Shoot 'em. They aren't protected, they will eat your pets and they can threaten humans". Sinse the fox family and I think a pair of Coyotes moved in a few blocks away (undeveloped parkland and stormwater management area)the rabbit population has really dropped of. Still too many of 'em, but not so bad you can't drive down the road without hitting a few any more. Wish something would start feasting on the tree rats! *** Posted via a free Usenet account from http://www.teranews.com *** |

Doggy-B-gone meets home shop machinist/EE. Telescopic sights. Parabolic dishes. Home-built stepper motor azimuth/elevation drives. Closed loop tracking system. Poor coyote doesn't have a chance. He'll have to start importing the poor things to provide a proper target-rich environment for the testing phase.

At close range and full power the whistle would probably destroy the microphone/tweeter. Place it at the focus of the dish, which is where the LNA was. Those dishes are offset fed sections of a paraboloid so it isn't obvious where the line-of-sight is. So, a tweeter down range, with a meter either with long wires or a spotting scope, to act as a mike/sensor. Hunt around until you're hitting the mike, adjust focus for max output (adjusting aim as necessary), then adjust optical sight so it's also aimed at the distant mike. Such a setup is slightly clandestine because it doesn't look like it's pointing in the direction it is. If mounted upside down it would look like it was pointed at the sky when it's line of sight would be horizontal. For that matter, why not mount the whistle at near the offending fenceline, connected, with a remote-actuated air valve?. Could be a pull-wire, or some sort of R/C item. Might work, but the dish does provide a lot of directional gain in the beam. A lot, a factor of several thousand over an omnidirectional whistle.

The trick would be to discover where the device points, and then put a sight on it for aiming at an actual target. A piezo tweeter makes a pretty good ultrasound microphone for testing. I have started to build one of these twice. The offending dog moved away both times before I completed it. I still have the dish, though. |

You may be right but I have heard the sound of an individual brain cell as it dies . Sounds just like a human scream . It was the brain cell of a lab rat . Not sure if that matters . About the only thing I shoot with a 22LR is Grouse . I was given an old Cooey single shot when I was a boy and have used it for grouse ever since . I used to shoot a lot of gophers when I was young but there are none near where I now live sadly . In open fields it is a lot easier with the Swift for coyotes . Ken Cutt And the 'red mist" the Swift makes as its trademark tends to not leave a wounded animal to crawl off and suffer. Gunner, who has used the 22-250 with equal success on yodel dogs, or the .243 in heavy barrel out past 400 meters when the .22 centerfires run out of steam. I really do love my Swift but if I were to do it over I would go for a 22-250 . Cheaper brass and a lot less throat erosion . I like the 243 but I decided for real long shots to use my 06 . I figured the extra practice with it would only help my hunting as that was my main gun . I can't say as it really helped as I have never yet made a 400 yard shot at big game . Doubt I will now . To be honest I made very few 200 yard shots while hunting big stuff . Ken Cutt |

We had a mixed dog an Coyote - it was a good English collie mix.
He lived to 14. He was a fantastic dog - knowing the wild and the work. We would leave it for a day or two with food in the house and water - come back with him sitting at the front window. Then he would eat and drink. A mix really helps - but the dog even knowing our friends well wouldn't let anyone near the house while we were gone. Gentle as ever. Good friend. But he wasn't a wild one.

I gave it to the wildlife officer up the road, who shot it in the end. None of the other two pups were able to be trained either, and were also destroyed......Its not uncommon to see them setting along the interstate watching cars go buy without a care in the world.

Around here you just call the Authorities. At $600 a crack, it doesn't
take long to get the message across!!!!!! Warning, this is a bit long. How I spent my last summer vacation. The dog across the street, a lovely Lab, was left alone by its owners, who worked at a local casino from 6pm to 2am. They left at 5 and came home around 3-4 am. The dog would bark in three barks, wait five seconds, and do it again, and again, and again for ten hours. We sent anonymous letters asking that they do something about the dog. No results. We called the police who gave us Animal Control's number. They said we could sign a complaint, but then we would have to go to court as the victim in order for the thing to proceed, and the neighbor would know who turned them in. We wanted to keep peace in the neighborhood, and since this guy looked like a Soprano affiliate, we opted to try something else. It was evening on the first call to Animal Control, and we got a recording. After that, we called and called and called every day. We were almost always channelled to a recording device, and when we did talk to a human, they said that they had sent out an officer, and the dog was not barking. I think they used their caller ID to avoid us. When we called in while the dog was barking, we would walk in front of the house with our phone and say, "Can you hear this dog barking?" woof, woof, woof ............. woof, woof, woof ...................... woof, woof, woof ....... (the sound of a Lab barking) One day, Animal Control called us at 4:30 AM to tell us that they had sent an officer out there, and the dog was not barking. My wife fielded the call, and acted just like she was up anyway. She's a light sleeper. Not sure why they called us at 0430. The dog kept on. We kept on calling. Finally, we saw our councilman at church. We told him about the dog, the 0430 call from Animal Control, and the repeated reports. He said, "I will take care of this," and that was all he said. The dog stopped barking a couple of days later. I imagine a couple of butts got chewed at Animal Control. We then got a letter from the DA's office asking us if we wanted to file a complaint and prosecute. Along with that question was a long list of things that we should know about before we filed a complaint, including that we could be prosecuted for filing a false report if it turned out to be unjustified, and that the people who owned the dog might sue US for harassment. But the dog did stop barking. I own two dogs, but I was having some serious thoughts about doing harm to that dog. Steve |

Larry, if you figure out a solution to that problem, let me know. I have the exact same problem behind me. I live outside city limits, and glad of it. I'll put up with the barking dog as part of the many freedoms I enjoy without things like city inspectors, firearms restrictions etc. I live outside the city limits, too, so county noise regs aren't as tight as city. Additionally, taxes are exactly HALF that of city dwellers. But I still don't want to put up with barking dogs. I'll see if I can get their name and phone number from their neighbors (who may be as angry as I am at the constant noise.) The noise level dropped 70% when I put in the dual-glazed windows, and with foam earplugs, I can get right to sleep even if the GDMFSOB dog is going off right then, so I've mellowed out a whole lot since it first started.

We used to have a couple of dozen cats. Now we have just two or three
black ones, which I think were simply too dark for the coyote to see, because he only came at night. I'm glad that the cats are gone, myself, but I do understand how this could be a problem for somebody else. |

The offending pet is across a 2 acre field, the RR tracks, and a street. I think atmospheric absorption might be excessive at much over 200 feet. Massa's book on Ultrasonics may have charts, if I can find it in the basement. The trick would be to discover where the device points, and then put a sight on it for aiming at an actual target. A piezo tweeter makes a pretty good ultrasound microphone for testing. I have started to build one of these twice. The offending dog moved away both times before I completed it. I still have the dish, though. If you would like to build 3 (so you're never caught short again, the NEXT time a mutt moves in) I'll see if Rex will go in with me to pay your costs. I don't have a lathe yet, but do have a spare Dish Network dish. What wavelength are those, anyway? (OoK, Wiki say "KU band.") I think DirecTV is in the range of 12.2 to 12.7 GHz, lambda of about 1.8 cm or 0.72 in. 22 KHz ultrasound has lambda of 1.5 cm or 0.6 in, pretty comparable. I'm stacked with projects at the moment, but I'll put a Hartmann back on the "ta do" list. Right now I'm trying to add electric drive to my boat lift winch and "goin' to the lake" time is getting real close even in MN. I'm adding some sprockets and adapting the motor and planetary gear drive from a scrounged ATV winch. I'd rather push a button than wind that 40" handwheel 40 revs with 20 lb of tangential force every time I wanna go out for a little while. A commercial gadget to do this runs over $500. I have about $10 in it so far, my time is free. Unfortunately, my wife has figured out the "my time is free" concept so there are plenty of honeydo projects. I'm also welding up a "drop dolly" so I can roll a new 36" high (on casters) tool chest under my 33" high bench. Man, I bet there are a bunch of wet, cold walleye fishers out there today for the opener, but they might well catch some fish with weather as lousy as it is.

A lab can be broken of the barking habit. Been there, done that. My beloved Charlie fell into that for a little while when she was about 5. I got a couple of friendly complaints. What finally worked was to duct-tape her mouth shut for about 4 hours on a cool day when panting wasn't required. Man, she hated that duct tape! After 4 hours of silent solitude and eventual resignation to her misery, the tape was removed none too gently and then she got a dairy queen as reward for her (enforced) good behavior. Man, that dog loved her ice cream cones! Lesson learned, was never forgotten for the remainder of her 18-year life. I know labs aren't supposed to live that long, but Charlie didn't know that. I don't know for sure that the ultrasonic headache would train a distant dog, but I kinda think it might. ARF --OW! And so on. |

If lead poisoning doesn't work, then just mix large quantities of rat
poison with some hamburger. Keep your own pets chained or locked up until the crisis is over. Any extra critters you nail this way are just a bonus. Had some neighbors out here in the country threaten to shoot our dogs for being on their property, well we're farm people too. Needless to say they got the pictures of their dogs on our property handed to them along with two shotgun shells. That took the wind out of their sails right quick. Anyway, what I was trying to say with that little story, is if one of the neighborhood pets gets into your coyote treat, oh well, that's the risk you take when you let your pets run free. |
