Hi Jim Jackson, Pernicious trolls like Fox's Mercantile are those who ruin Usenet for all. o Hence it's important that _all_ of us discourage their despicable actions Thank you for being an adult above - so we didn't waste time on obvious facts. o As you observed, it's trivial to prove what Fox's Mercantile always does (as he did in this very thread - & always does - because he's a troll) Literally every time I post, I have Fox's Mercantile infantile responses to deal with, but what's worse is he attempts to troll derail _every_ thread. Others... more so than just me... need to help put a stop to this o Otherwise this newsgroup, like many others, is handed to these trolls. All Fox's Mercantile did in response to the request for help - was troll. It's what worthless pieces of **** trolls do, as you & I are aware... o But, like Snit, this Fox's Mercantile is particularly pernicious about it In summary, while yours is a great question, you're asking it of the wrong person, since you should be asking Fox's Mercantile why he does what he does. I would be happy if this infantile troll would just stop sniffing my ass o I repeat: If Fox's Mercantile ignores me - I'm happy to ignore him. He's a worthless piece of **** troll anyway... o So he can't possibly ever add any adult value to any thread topic. The problem is that if I don't make it obvious to all here what he does... o These cowardly infantile bullies will never stop ruining this newsgroup. -- Pernicious trolls like Fox's Mercantile are those who ruin Usenet for all. |

Wish I had the stamina - I'd put it to better use. Jim - going back to lurking Chuckle. Allegedly, computahs are labor and time saving devices. It would seem that we are experiencing a demonstration proving quite the opposite. I've been submerged in Usenet for far to long to recall what I did for entertainment prior to about 1981. I suspect it was something equally useless and likely laced with debauchery. Someone wiser than me once noted that Usenet conversations were really not for the benefit of the participants. Instead, they merely establish a mostly permanent record of the participants point of view, so that some other future Usenet conversationalists can use them as references. The lack of a clear winner in all Usenet conversations is clearly proof that winning the discussion is not a priority. Many of the successors to Usenet actually award points or badges for being the most cited. The only good part is that where there are no clear winners, there are also no clear losers. Let the most mediocre position win. This probably won't improve your understanding or stamina, but might prove amusing. I wrote it when I was thinking along lines similar to your lament: http://www.learnbydestroying.com/jeffl/crud/genesis.txt And the lord looked upon the Usenet wasteland and proclaimed "I have given unto thee a temple upon which thou may rant. Instead, though hath turned my temple into a den of iniquity and dung hole of misinformation. Unto thy ancestors, I gave 10 commandments, but unto thee I shall give but one; Thou shalt not post what thou also find unworthy of reading." Hmmm...

You just need to widen the channel. While there are 2.4GHz routers available that have a 40MHz channel bandwidth setting, I prefer not to use it because it reduces the available bandwidth to other users on 2.4GHz. If one is sufficiently clueless to use a 40 MHz channel set to CH6, it will effectively trash most of the 2.4GHz band. Since Wi-Fi pollution can be symmetrical, it also makes the receiver susceptible to more interference. Stay with 20MHz channel bandwidth on 2.4GHz. On the other foot, the minimum channel bandwidth on 5GHz is 40MHz (depending on channel selected) with an option to use 80MHz or 160MHz for 802.11AC and AX (Wi-Fi 6). https://en.wikipedia.org/wiki/List_of_WLAN_channels#5_GHz_or_5.9_GHz_(802.11a/h/j/n/ac/ax) With 1024-QAM, 802.11AX can theoretically do 1.2Gbits/sec in a 160MHz channel. Your mileage will certainly be less. The test below was to demonstrate something else. However, it does show what can be done with 5GHz. http://www.learnbydestroying.com/jeffl/FLUG-talk-2015-02-28/802.1a%20direct.jpg Unfortunately, the radios at both ends were only 802.11a, so the speed never went above 75 Mbits/sec at a distance of about 5 meters. It also uses Jperf 2.0.2, which doesn't work very well above 100 Mbit/sec. I should have used Iperf 3, which works well into the gigabit range: https://iperf.fr/iperf-download.php My home network is now mostly gigabit, so I could easily run some 5GHz performance tests with a later version of Iperf 3. However, no pretty graphs as nobody has bothered to port the Java code to work with Iperf3. I'm a horrible programmist, so I won't attempt it. Anyway, the performance limiting factor is usually interference from co-channel users and noise sources. You could have all the bandwidth in the world, the most efficient modulation scheme, maximum legal RF power, and still not be able to communicate very well or far if there is an interference source nearby. In other words, one needs to do more than just "widen the channel". -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

You can run the math to explain to him how high that pole may need to be. (We do that stuff by trial and error - but you may know the math better.) Sigh. I've lost count how many times I've done that in this newsgroup. Start he https://www.proxim.com/en/products/knowledge-center/calculations/calculations-fresnel-clearance-zone 800 ft is not far enough apart to worry about the curvature of the earth. 800ft / 5280ft/mile = 0.152 miles At 2.4Ghz, the Fresnel Zone is 9 ft radius at the midpoint of the link. Therefore, the antenna at both ends of the link need to be at least 9 ft off the ground, or 9 ft above any major obstructions (fences, trees, buildings, cars, etc). Actually, it's somewhat more complicated if I throw in fade margin, frequency selective fading, and system availability, but we won't need to go there for this example. At 5 GHz, the Fresnel Zone radius is only 6.3 ft. Therefore, the antenna pole can be 2.7 feet shorter. Please advise the OP on the math so he knows how high to mount the radio. Methinks we've lost the OP long ago. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Congratulations. You'll now enjoyably find everything you knew disappainting or being replaced by new kids on the block. I don't see any of those filling your shoes here and I usually only bother to lurk to see what you are posting.

You can run the math to explain to him how high that pole may need to be. (We do that stuff by trial and error - but you may know the math better.) I've run cantenna line-of-site over 400m reliably for years. I didn't measure the fresnel zone but a farmer's apple tree in his front must have encroached the signal line every few years and he would kindly lop a few branches, restoring normal service. I have a note of the speeds somewhere but the system gave me office access from home, home broadband via the office and all I remember is that the Wi-Fi speed was better than the rather poor broadband speed available at the end of a long exchange line. After moving several years ago from the little hamlet (60 properties) the pathetic broadband (I think I had one of the best connections at 2mbps) was replaced by FTTP. I don't think I could have got mi Wi-Fi signal to keep up with the resulting 80Mbps broadband. Those we now Zoom with in that hamlet are always very clear and no blurring motion issues - I'm somewhat jealous.

The office is closed, the bank accounts emptied, and much of the equipment donated or sold. Enjoy your retirement, my friend! Thanks. However, it's not easy to find enjoyment while trying to adjust to Covid-19, dysfunctional government at all levels, impending economic collapse, limits on travel, increasing weather related problems, an increasing homeless problem, and probably increased taxes to keep the economy afloat. Health problems and advancing age increasingly limit my activities. I can survive on Social Security payments and the 80% that Medicare provides, but suspect those benefits to will eventually be reduced by inflation as the government resorts to printing money to finance its activities. I expect my "retirement" to more closely resemble living on unemployment with the added bonus of having no debt and a modest bank account. Since I have no children or immediate family, I could easily have obtained a reverse mortgage on my house, and lived off the cash. However, the recent fires in California might make that impossible due to increasing difficulties obtaining replacement value fire insurance, a basic requirement for a reverse mortgage. In other words, the long term prospects for an enjoyable retirement look rather grim. However, before I blunder on into this dismal future, I have an immediate problem to deal with. I brought about 75% of the contents of my formerly palatial office to my house when I moved out. There was no time to do sorting, only time to box everything and move. I moved it in small increments because I have no garage or storage space at the house and because I had to carry the boxes up about 50 stairs. The boxes are now piled up both inside and outside the house. Much of it is covered with ash that is still falling from the trees due to the recent nearby fires. Rain will likely arrive in a few weeks and nothing outside is protected. I need to deal with that immediately, but can't during the current heat waves. At least I won't be bored looking for something to do. Incidentally, it's now 6AM and 75F (24C) outside. NWS predicts the temperature to rise to 101F (38C) today. I might be able to do 2-3 hrs of box shuffling today. It's likely that the local power company, PG&E, will intentionally disconnect the power to prevent falling power lines from starting more fires and to reduce the load on the power grid from air conditioning. Thanks again for the hopeful thoughts, but this is not the retirement that I had planned and is unlikely to be enjoyable. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Given the price of real-estate, and the cost-of-living in Santa Cruz, given that you are apparently single, given that you are apparently not overly happy about the climate, have you ever considered relocating to a more amenable part of the country? When we moved 12 years ago (just across the township), it was akin to shedding a skin. The divestiture of unneeded *stuff* was pretty immense and very cleansing. We have been vary careful not to re-acquire since. It really does make a difference. But, a more distant move in your case may solve a number of financial, physical and logistic issues all at once.
Best of luck with it. My wife is retired, my identified date is June 30, 2022 when my major tenant ends its lease. Until then, my wife and I are busy 'feathering our nests" so that when we retired and our income drops by six figures we will have few expenses and no debt on what amounts to be two very nearly maintenance-free houses. Take care! |

Actually, I have done some online looking at some possible places to relocate. The exodus from California seems to be mostly to the northern and eastern states: https://www.mercurynews.com/2019/11/04/691145-californians-left-last-year-what-state-did-they-go-to/ Texas seems to be the largest, with a predictable reaction: "Why Texans Don’t Want Any More Californians" https://www.theatlantic.com/ideas/archive/2020/01/the-truth-about-the-california-exodus/605833/ There are also a fair number of YouTube videos on "Why you don't want to move to [insert name of state]". After I work out the migration pattern, the next step would be to decide if I want to move to where everyone is going, or if I want to avoid those places. Right now, I don't know. I originally moved to Santa Cruz from the Smog Angeles area in about 1973 because it was less crowded. I wanted to get away from the crowds. Before Covid-19 drastically cut down on the traffic earlier this year, Santa Cruz traffic had become as bad as Smog Angeles over the past 47 years. If I move, I don't want to become part of that problem. However, the main reasons I haven't moved somewhere else is that I don't have any urgent need to move, and that my house has some problems that will either be too expensive or difficult to fix economically. It's a can of worms I don't want to open at this time. There's also the problem of my lack of longevity. If my family history is an indication of how long I'll live, I probably won't live long enough to enjoy the change of location. When we moved 12 years ago (just across the township), it was akin to shedding a skin. The divestiture of unneeded *stuff* was pretty immense and very cleansing. We have been vary careful not to re-acquire since. It really does make a difference. But, a more distant move in your case may solve a number of financial, physical and logistic issues all at once. I know the feeling. Several of my friends have become minimalists. Unfortunately, I've been the recipient of some of their accumulated junk. I would say they were most successful in what they were trying to accomplish. For me, it's quite different. While I'm not quite a packrat, I do tend to accumulate "stuff". Since I don't have a family and have yet to immerse myself in public service and volunteer organizations, I tend to replace these with gadgets, things, gizmos, and goodies. I fix things, I enjoy the work, and would happily spend the rest of my continuing to save "stuff" from a premature demise in a landfill. I guess I'm an eco-freak of sorts. Moving wouldn't change much. Best of luck with it. My wife is retired, my identified date is June 30, 2022 when my major tenant ends its lease. Until then, my wife and I are busy 'feathering our nests" so that when we retired and our income drops by six figures we will have few expenses and no debt on what amounts to be two very nearly maintenance-free houses. Nicely done. Sounds like you have things well planned and organized. I thought my plans were similarly set. Then, I had to deal with some nasty medical problems, a pandemic, wildfires, and an evacuation. The assumptions I made in planning my retirement have not gone up in smoke yet, but are likely to do so considering the circumstances I itemized in a previous rant. May your ration of luck survive and hopefully, you won't need to deal with my problems. Take care! Thanks. Time for a fast dinner and off to a friend to fix a Brother sewing machine and a Baby Lock. As long as there are things that I can fix and that need fixing, I should be ok. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Thanks again for the hopeful thoughts, but this is not the retirement that I had planned and is unlikely to be enjoyable. I didn't plan on becoming 100% disabled in my late 50s. My last day of work for someone else was the Friday before 9/11. I kept busy working on computers for others who couldn't afford to take them to a shop. I can no longer even do that. My legs are so bad that I have to prop them up more than 10 out of 24 hours to keep the scar tissue from opening. I couldn't do it last night. There was a large puddle of plasma under my left foot this morning. I deal with it, but only having two hours a day to do everything is a real pain. I had two bad falls in the past year. It looks like I'm going to have to go to a walker or power chair before long. Why not open a Ebay store to list what you don't want to keep, as you sort out the boxes? It will help you get rid of some stuff, and hopefully give you some extra cash. God Bless you, my friend! |
