I knew what an interpolation sounded like on that player, a little chirp when a block of data would not error-correct. This was different, but maybe the player's chip set had some different method of covering up buffer errors that tried to fake the data. And, I could easily see at the lower speed that it could get lots of buffering errors if the speed was unstable.   Jon

I assume there has to be some sort of speaker in it.   I do wonder what this "ultrasonic" frequency really is? Humans are supposed to hear up to 20K. (Most of us dont hear that high). So, if this device is say 25K, we cant hear it. But do dogs hear that high? Does anyone really know the hearing range for a dog? If someone claims they do know, how can they prove it? It's just like people say horses do not see color. I disagree based on trying different things, like changing feed pail colors, but I cant really prove it.   There is another solution. I used this one when I had a dog that barked all the time and refused to stop no matter what I did to train or scold him. One day I just called the Humane Society and told them I had a dog for them. They took him, and I no longer heard any barking. Now I have some cats, a goat, a donkey and some miniature horses. ALL are better pets. I never want another dog.   Man's best friend is any of the other animals I mentioned. Man's biggest nuisance is a dog.   If you (the OP) does connect a scope to this thing, I'd be interested in knowing what the frequency is.   By the way, I once lived in a house that always got mice in the house. I bought an ultrasonic thing that was supposed to chase the mice away. WORTHLESS GARBAGE! What did work, was mouse traps and cats. (And eventually moving to another house that did not have mice entry holes).   ----------

That's your limit, at least for your dog and most likely it's breed.

That's your limit, at least for your dog and most likely it's breed.   Careful - stating the obvious to Old School is an exercise in futility.   I am emphatically not a dog person - but we have kept dogs for the last 30 years, always two, always including at least one Golden Retriever. Now a Scottie and a Golden.   There are *no* bad dogs - only bad humans. This includes pit-bulls, which are dangerous as much due to their breeding (by bad humans for dog-fighting) as by their natures - highly protective and aggressive, no surprise there.   As to cats, they hear at least as well as dogs, but are focused on a slightly different part of the spectrum.   Hearing: There are sounds, and there are over/undertones. One may not hear something specifically, but one may be annoyed by artifacts created by a given sound. And a pure sine-wave of a specific frequency will sound quite different than a note struck on a piano or played on a violin due to those artifacts.   Peter Wieck Melrose Park, PA

Use an ultrasonic transducer for a mic & multiply it with variable 20-100kHz signal.

It was bought at B&M but I didn't keep receipt. Did consider a mic attached to laptop but thought ultrasonic would be outside the mic's range. Used to have a scope when I fixed TV's but gave it away.

There may be a trial offer.   Gareth is correct for equipment not designed for suppressing the mechanism noise producing the above 22000 motion.   There is an inbetween where a substitute noise broadcasts the mechanism's activation .... as a jet plan roar or a 57 Chevy with glass packs ...something not immediately noticed as unusual.   devices are sold to deter rats.

Which means they are lonely. A dog that is not lonely will not bark except for a reason. And, as it happens, one typically wants the dog to park *when* there is a reason.   No-Bark collars stop all barking, good or bad.   If you have an older dog that is going deaf, and is left outside for any length of time, it *will* bark. It is called self-stimulus. Again, lonely dogs bark.   Generally, dogs are a commitment that takes time and consideration, especially as they get older. Our retrievers have lasted 14, 13 and the incumbent is 7 years old. We have a Scottie who is 8, but smaller dogs tend to last longer. And we have two cats, 7 & 4 who might well last 20+ years. In any case, the animals all take considerable comfort from each other.   Peter Wieck Melrose Park, PA

I don't know if that proves his worthlessness or not but I always told my two sons to 1) find someone like your mother and 2) make sure she's a dog lover.

"pfjw@aol.com" <pfjw@aol.com>: May 16 01:38PM -0700 Generally, people who have pets, and have done so for a long time are more 'worthwhile' in relationships. They already understand the concept of commitment.   And, note how the pets behave!   As to multiple cats:   1 cat is OK. 2 cats is better. 3 cats is very bad. 4-or-more cats is a function of how much space they have. A woman who keeps horses and has barn cats is a different concept than a woman who keeps multiple cats in the typical NYC walk-up apartment.   Peter Wieck Melrose Park, PA

Trevor Wilson <trevor@SPAMBLOCKrageaudio.com.au>: May 17 08:43AM +1000 The N. Cook thread got me to thinking about some of the worst customers I've had in this business. The one that sticks in my mind turned up back in around 1982-ish. I had been operating my business for about 2 years, after serving as service manager for Marantz Australia.   Anyway, this guy (let's call him Mr Jones) turns up with his Marantz turntable for repair. At that time, it was close to 7 years old and in pretty decent condition. Naturally, there were the usual fine scratches on the lid, which inevitably occur with acrylic covers. No deep scratches and the timber was in good nick. He did not supply the turntable in it's original packing box as clearly recommended in the Marantz manual.   A few weeks later, job done and I called the customer to collect his turntable. Cost was around AUS$100.00. As was/is my practice with turntables, after the job was completed, it was stored on a carpeted rack, with 200mm spacing, so nothing can ever be placed on top of any turntables stored within. Subsequent to my 'phone call a man I did not recognise turned up to collect the turntable for Mr Jones several weeks later. I asked to see the job ticket, which was duly presented. Satisfied, I retrieved the turntable. Mr Smith looked at the turntable and pointed out the (very) fine scratches and claimed that they were new (they clearly were not). I explained as much and Mr Smith said that he would not pay for the repair and I told him that he would not be able to collect the turntable.   2 weeks later, I received a letter from Mr Jones demanding that I supply a new cover, which was available from Marantz for AUS$375.00. I sent a letter back to Mr Jones explaining the following:   * I did not damage the cover. * Although I did not damage the cover, if he wanted his turntable to be kept in perfect condition, that he should carry it around in it's original packing box. * Mr Jones had not yet sighted his own turntable and was relying on the claim of one of his employees!   Additionally, I cited the NSW Uncollected Goods Act, which allows a repair agent the right to sell uncollected jobs, after 90 days, provided all possible efforts are made to contact the owner/s.   Mr Jones turned up a week later with the cash to collect his turntable, whereupon I explained that I did not wish to conduct any further business with him. Ever.   FWIW: I have retained repairs for as long as 2 years, waiting for customers to collect their jobs.   -- Trevor Wilson www.rageaudio.com.au

I lit an added LED for connection to power not grnd. All the successful connections here go directly to grnd thru the relay. Not thru load.

Keep in mind how delicate a proposition it must be to maintain their faith.   Many "decent" speakers have one/the-other/both inside. It is largely about real-estate and price-point as well as how critical the value might be. For critical and highly 'designed' applications, film caps are the only way to fly. For things that are less critical, an electrolytic might do just fine.   Maggie speakers are an example of where there are multiple choices. Many after-market 'upgrades' to their outboard crossovers use either/both, although it is my impression that most factory-originals were film.   Suffice it that any speaker cap must be able to operate in an AC environment, meaning NP for electrolytics. No more complicated than that at the most basic level.   Peter Wieck Melrose Park, PA

I don't know how to get my car fixed >without signing one of these things unless I do it myself.   Here in California, behavior like that on the part of any auto-repair business would be a violation of the law, and they could have their license pulled for doing it.   Here's the page on the legal situation and advice in California... other states' laws may vary.   https://www.bar.ca.gov/consumer/auto_repair_guide.html   They give some very good advice. In particular "Know Your Rights", and "Before you sign, be sure you understand the work the technician will do. Your signature means you agree to pay for the repairs up to the amount specified. Do not sign a blank work order."   A work order is a contract. As with any contract, the terms are largely negotiable, and it's not binding until it's signed. Signing a blank work order (one without an agreed-upon upper limit) is legally like signing a blank check. Not a good idea. Revising a contract offered to you, before you sign it, is your right: whether the shop chooses to accept and be bound by the altered contract is the and decision.   If the "fine print on the work order seems to say I'm authorizing anything they do", feel free to draw a line through it with your pen ("striking it out") before you sign. Initial and date the line-out when you do it, so it's clear that you removed it from the contract.   If they haven't filled in an amount for doing the estimate, ask specifically "What do you charge for investigating the problem and giving me an estimate for the repair?"   If they say there's no charge, write "$0.00" in the maximum- authorized-charge area before you sign it. If they give you a price, write in that amount.   Then, sign the authorization. Keep one copy.   At that point, if they do any work on the car, then they have accepted your contract as it was when you signed it. They're bound to the amount on the form, and can't legally charge you more than that.   If they go ahead and do a repair without giving you the estimate and getting your authorization, it's on them.   If they refuse to work on your car without having a blank work order... leave. Find another auto-repair shop. And, consider reporting the offender's behavior to your state's licensing organization.   [Disclaimer: I Am Not A Lawyer Nor Do I Play One On Television.
