Re: [Repeater-Builder] snide remarks

[snip] Gee. Tony's intent and meaning sailed right over the top of your head, didn't it? Are you normally this oblivious, or is this a special case? Am I justified in calling your powers of observation into question? If I am, is a public forum the proper place to do so? Let's return to the events that led to Mr. King's ire, shall we? A new repeater builder asked how to invert the sense of a squelch signal, and one of the august (yes, august is properly capitalized. Look it up) members of this mailing list jumped on him with all four feet. Yes, I just did imply that the jumper is an animal; allow me to make it explicit by calling him a jackass. For the wasted bandwidth, he could have answered the question two or three ways; instead, he chose to assuage his own feelings of inferiority by lording it over someone he saw as lower on the totem pole. Was that justified? Another member of this list attempted to dissuade a would-be repeater ownder from erecting another 10 meter repeater. In the course of that discussion, someone mentioned coordination -- and another august member of this list loosed a highly unprofessional broadside at someone that was not present to defend himself. You yourself have continued to beat the place in the road where there used to be a greasy spot where a dead horse used to lay, hijacking Mr. King's thread in order to do so. What is your justification in doing so? Now allow me to add one of my own. A new member posted in HTML. After a request that he quit doing so, he did. He left Micro$oft's damnedable smart quotes enabled, though, and thoroughly scrambled the presentation in my xterm window on my Linux computer. When I asked him to turn them off, yet another august member of this list set up a straw man and thoroughly demolished it, implying as he did so that I was less than capable if I could not parse meaning from within HTML coding. I didn't think he needed to be set straight in public, so I sent him a private E-mail informing him that his bogus argument was, in point of fact, bogus. See, Micro$lop used control characters for their damnedable smart quotes, and terminals -- such as xterm, the X Terminal -- use control characters to, well, control the behavior of the terminal. They ring the bell, or turn off scroll, or reposition the cursor, or clear the viewing window, or any number of other things. That's why they're called control characters and why the key used to create them is called the control key. Apparently, instead of correcting him in private I should have exposed his ignorance in public and held him to account for it. Mea culpa. I have corrected my error here. Mr. Mackey, do you care to address even *one* of these three examples of what Mr. King is inveighing against, or do you merely wish to continue to beat the spot where a dead horse used to lie?

[Repeater-Builder] Re: radial tire static?
From: na6df [EMAIL PROTECTED] Date: Wed, 17 Nov 2004 21:11:58 - Subject: [Repeater-Builder] radial tire static? Not repeater related so much, but I thought the great minds here might know... One of my corporate bosses, a ham, is having his bridgestone tires generate static while they are rolling, interfering with AM radio reception. I know somebody used to sell a powder to put in the tires that dissapated the static, but can't find any info on it now. It has to do with some problem with low rolling resistance tires that have low carbon content.. Any ideas? thanks! The one I remember hearing about was a graphite powder that would make the carcass more conductive. In use, a quantity was injected in the tire before it was inflated. NB: This material may be limited to tube tires at present. The wheel bearing grease also caused some problems by insulating the tires from the frame, so the bearing assembly would have a spring that bore on the bearing cap and on the spindle to keep them at the same potential.

I was 19, with a second class commercial radiotelephone license so new the ink wasn't dry yet (and since the FCC ran them off en masse on a line printer that is saying something). I interviewed for a job based on the license, and the gentleman I was talking to said, You have a second 'phone? I do too -- had to take the test three times [I think; this was a while ago] before I passed it. How many times did you test before you passed? Being honest, I said, Only once.

Re: [Repeater-Builder] Re Circulator
From: Eric Lemmon [EMAIL PROTECTED] Date: Thu, 07 Oct 2004 18:49:13 -0700 Subject: Re: [Repeater-Builder] Re Circulator Andy, My understanding of British radio terminology is not complete, so I am a little confused by your statement about the receive port of the circulator. In circulator (isolator) applications I am familiar with, the input of the circulator connects directly to the transmitter output, the output of the circulator connects to the TX input cavity of the duplexer, and a 50 ohm load is connected to the side connector. I learned that was an isolator. The product I work on in my dayside job has a four-port circulator. The transmitter is connected to port one, which passes any signal clockwise (for the sake of argument) to port two. The antenna is connected to port two, the receiver to port three, and a load to port four. Since all signals are passing clockwise, from port one to two, port two to three, port three to four, and port four to one, the load on port four is not visible to the transmitter. The receiver on port three is not visible to the transmitter, assuming the antenna absorbs all the RF. And any signals that the bandpass filter in the front end of the receiver rejects do not go back out the antenna, as they would have to go counterclockwise to get there. Ditto received signals and the transmitter; the circulator won't allow them to go that way. The same product also has an isolator in it at an earlier stage. What goes in port one comes out port two; what comes in port two is turned into heat in the load on port three. The energy coming in port two can't go to port one because it's being steered clockwise by the isolator. Circulators are very common in microwave applications as they allow the use of a single waveguide for both transmit and receive, minimizing the problems inherent in running what is essentially a rectangular pipe from the radio to the antenna and the problems of evenly illuminating a reflector with two different feedhorns. I have casually wondered upon occasion if a four-port circulator in a repeater would confer any benefit, possibly increasing isolation and allowing the use of smaller, hopefully less costly duplexers. de kg7yy [snip] Yahoo!

[Repeater-Builder] Re: Weather Radios
From: Mike WA6ILQ [EMAIL PROTECTED] Subject: Re: [Repeater-Builder] Re: Weather Radios [...] FWIW, the SAME code definitions are in the referenced PDF. The encoderis even somethng that might be worth writing as a sound card utility, provided the sound card has the requisite transient response and stability. I'd like to see that as a embedded processor function on a repeater controller add-on card - in the same sense as the RLC-MOT is a add-on card. Picture the ability to take a old 160mhz receiver strip - let's say from a Motrac - something that would normally be considered as a doorstop. Buy a cheap crystal from somewhere on the local weather channel. Add this board - call it the Simple-SAME decoder between the audio output and the repeater controller input. You instantly have a high performance SAME receiver for the cost of the Simple-SAME and a crystal. I admit I wasn't thinking that far into it -- I was hung up on the notion of generating SAME codes for the purpose of testing decoders. That would be a slick little gadget. Since the SAME codes include EOM that would allow the repeater to go back to normal operations when the message ended. I see a need to control warnings coming from the decoder independently, though; after the horn has blown for a tornado warning one's users probably wouldn't be any too interested in a severe T'storm watch. Possibly something like the decoder outputs as one input to an AND gate with the other being a latch, then all 31 AND gates feeding into a single OR gate. [snip] de kg7yy Yahoo!

Re: [Repeater-Builder] Re: Weather Radios
From: hwingate [EMAIL PROTECTED] Subject: [Repeater-Builder] Re: Weather Radios The 1050 hz tone is the original arert tone that was used before the SAME system was installed. It is still transmitted with a duration of 8-10 seconds,is not area specific and will give a warning for the whole coverage area of the station, sometimes as much as 5000 square miles. Generating a SAME tone is not for the faint of heart. It is digital and has such oddball parameters as 520.83 bps data rate, a digital 1 = 2083.3 hz , a digital 0 = 1562.5 hz. For more than you ever wanted to know about SAME go here: http://www.nws.noaa.gov/nwr/same.pdf Henry, K4HAL Henry, I don't think it would be all that hard to build a FSK audio oscillator to work with a 1.92 mS wide mark and space tone (which is what 520.83 bps translates to) at those frequencies. The phase continuity requirement may be a little tricky. though. FWIW, the SAME code definitions are in the referenced PDF. The encoder is even somethng that might be worth writing as a sound card utility, provided the sound card has the requisite transient response and stability. Guess I need to dig up the sound libraries and read the furnished manual on them. de kg7yy Yahoo!
