The teacher told me most of the really bad kids have been suspended by now. I guess there's no way to not leave a child behind when they *want* to be left behind. I think, in California, they can be emancipated at something like 16, which is the age these kids are around. |

I left school at 16. Quit when I had the earliest chance. It really wasn't the place for me. I moved out of our home too, went out into the world and made my bones, retired at age 50 and have no regrets. IMHO some kids should not be in government mandated skewls, er, schools. |

I'm sorry about that Oren. Unless you're happy about it. School isn't for all kids, especially the kind of kid who likes to do it his own way, and the ones who don't like sitting down at a desk for 180 days in a row. |

My best day at school came when I was 15. It was English class. I tore open a ream of paper and tossed it out the third-floor window. The wind scattered the sheets like tickertape, all over the huge lawn. It was the most beautiful sight I'd ever seen. The teacher told me to pick it up. I felt like Br'er Rabbit: "Don't throw me in the briar patch!" It was great! I wished I'd been allowed to spend all day every day out picking up papers, from the time I was 5. I had another good day at 17 when I whipped out my toothbrush and toothpaste and started brushing my teeth in Calculus. The teacher turned pale and stood over my desk menacing me with karate chops and karate kicks. Then he took me to The Office. I thought it was turning into a bad day because if the principal misunderstood the situation, that could tarnish my reputation. When he sentenced me to 5 days' detention, I saw he was doing his best not to bust out laughing, so I knew my sterling reputation was safe. I loved detention. It was the only class where teachers kept their mouths shut. That teacher didn't even know Calculus. Every day, I had to sit and listen to him talk about how he adored Adolf Hitler. |

One of mine was walking down the hallway, past open classroom doors while carrying the front of a wall locker under my arm. The looks were priceless! The school board's maintenance crew was going to order a new panel of three doors because of broken spot welds. I told them to let me take it to the metal shop, to repair it so three kids wouldn't be without lockers for weeks. I brought it back 15 minutes later, with some nice burn marks in the ugly brown paint. The other kids gave me strange looks for months after that. :) -- Anyone wanting to run for any political office in the US should have to have a DD214, and a honorable discharge. |

We actually joked, a few times, about the Tacoma Narrows bridge, and, yes, I think just about everyone has seen that video of the car on the bridge and the person getting out and making it just in time. This bridge isn't nearly as long. It's only about 100 feet long, by 10 feet wide, supported on one end on the ground and on the far end about 40 or 50 feet up in a tree on a (very) steep slope. Here's what the first two 16-foot-long sections looked like today, when we ran out of oiled wood: https://c4.staticflickr.com/4/3945/15459995717_3722bf0914_b.jpg I'm currently learning how to wash good clothes to get the oil out! :( |
Ricardo Abreu <ricardo.matos.abreu@gmail.com>: Oct 27 04:08PM -0700 Had a little time to check the microwave oven again. 1) First, I checked if a short was developing in the magnetron between cathode and anode (case) when the filament gets hot, but it doesn't. If you are wondering how I did it, I disconnected HV and connected a resistor from one of the filament's terminal to case, and checked for voltage across the resistor. Repeated this for the other filament's terminal; 2) Took the magnetron off. There were no cracks in the magnets (visible, at least) as Sam suggested; 3) Connected the filament (always HV disconnected) and powered the oven with lights off. The filaments clearly glows; 4) Checked HV transformer for signs of arcing or shorts, but none visible. Also, windings are not superimposed, they are placed side by side in the same leg, which somewhat reduces chances of arcing between windings; 5) Changed the HV diode for a new one (the cheapest part), but to no avail; Now I'm stuck, and it seems my only option (unless you have a better idea) is to start replacing parts until the thing gets alive again. HV cap is still inexpensive. By your experience, which one fails the most: transformer or magnetron? |

Here's a list of FM licenses. Translators have a 3 digit number in the callsign. If it's a flaky receiver you may be interfering with aircraft. http://fccinfo.com/CMDProFacLookup.php?sCurrentService=FM&tabSearchType=Within+Search&ArchiveRecords=N&sKilometers=100&sLatitude=39-17-25&sLongitude=76-36-45&sPlace=Baltimore |

My initial thought was that perhaps the station is operating a "translator" (repeater) on 88.7-ish, but a search of the FCC database doesn't turn up anything. There are two translators licensed to Maryland on 88.7 MHz: W204BA in Oakland and W204CL in Lexington Park. Both belong to Grace Missionary Church (d/b/a Grace Christian School). Some Googling shows those affiliated with a small religious radio network, but it's possible they could be re-transmitting 88.1 for some reason. Both transmitters are fairly low power, as is typical of translators (250 and 55 watts, respectively), and given the distance (2-3 hours away) I doubt there would be much overlap in coverage area, if any. So... that possibility fairly well eliminated, I think the best bet is to zip off an e-mail to the station and ask what's going on. Looks like those are public radio stations, and my experience has been that the engineers at those types of facilities are typically pretty helpful when it comes to resolving reception concerns and addressing technical questions. If you do that, I'd be curious what you dig up. Since you are able to reproduce the behavior on multiple radios, I doubt it's a problem with the receivers. |
dplatt@coop.radagast.org (David Platt): Oct 27 12:01PM -0700 In article <v7ss4allgf4oosl9rud3hpt3g3rmr6m58a@4ax.com>, >88.5 to what I'd estimate is 88.6 or .7 or .8 I get 88.1 again. >How is that happening? I know about harmonics, but that doesn't apply, >does it? There are at least three ways in which you can end up with a strong FM station at two locations on the dial. (1) As somebody else suggested, it might be a "translator" - a second transmitter carrying the same program material on a different channel. Translators are sometimes used to "fill in" a station's service footprint - e.g. to provide service to an area on the far side of a mountain from the primary transmitter. (2) Image. FM receivers are almost always superheterodyne receiver... they have a local oscillator which is tuned either above, or below, the station's frequency by a fixed amount (most commonly 10.7 MHz). "Mixing" of the station frequency and the local oscillator create an "intermediate frequency" signal at (e.g.) 10.7 MHz which is then filtered, amplified, and decoded. This architecture can cause a station to "reappear" on the dial, if you're tuned away from it by twice the intermediate frequency (e.g. by 21.4 MHz) - a second "image" of the station appears on the dial. Good FM receivers have enough selectivity built into their "front end" to keep this problem to a minimum - the tuner "filters out" the station at the image frequency efficiently enough, before mixing with the local oscillator, to keep it from "reappearing" or interfering with a desired station (image rejection is often 90-100 decibels, if I recall correctly). (3) Intermodulation. If you have two strong stations nearby, their signals can mix (either in the receiver front end, or elsewhere) and create "spurious" signals located on either side of their true locations on the dial. These spur signals will often be noisy and distorted. What you're describing doesn't sound like an image problem (#2) because the second "copy" of 88.1 is so close to it on the dial. It might be intermodulation, or the 88.1 station may have a translator off in the distance. Due to recent consolidation of radio-station ownership (both commercial service and "noncommercial" FM), the signal at 88.7/88.8 might be a formerly-independent station in another market, which has been "bought up" by the ownership of 88.1 and is now simply rebroadcasting its signal. |

This sounds very likely; if it is due to front-end nonlinearity, it's possible to test/treat it by inserting an attenuator between the FM antenna and the receiver (assuming the receiver has a plug-in antenna). Lower the signal level, and the spurious response should go away. Alternately, one can attenuate (filter) either the interfering FM station or the (presumably AM) difference-frequency station: this can be done with a lossy antenna+load placed near your radio, so can apply without access to antenna terminals. |

You can enhance inclusion by repeating a keyword three times. Not the same as a + but definitely improving the results. Cheers! |
