I pickup such things on the well beaten path to enlightenment. I threw the following together last night to deal with a case of over-planning: "Those that only live in the past are never disappointed by the future because they make no plans. Those that live only for the promises of the future tend to forget the lessons of the past, and soon repeat them. Those that live only in the present have both problems." It looks like wisdom but it's really just a philosophy formula. take two diametrically opposed observations and follow them with a self contradictory conclusion. Once you know the trick, it's easy. Now, if I could only fix my crappy arithmetic. No, I'm not willing to wade through a mountain of crap to find one or two good posts. Well, that's fine. I tolerate considerable abuse before giving up. Many years ago, I was working as a 2way radio tech. My boss was a compulsive liar and somewhat of a crook. Most of what he told me had to be double checked before acting on it. However, I tolerated it because the few gems at the bottom of this dumpster were well worth my paying attention. It was low efficiency operation, but I was willing to pay the price. But maybe I am a bit shell shocked. I post on the s.e.d group and there are a fair number of true a-holes who would rather insult you than to answer one legitimate question. Again, don't pass judgment on the person if the information is worthwhile. Phil Allison in s.e.d is a good example. With few exceptions, his opinions and info are quite good and accurate. He can often see what others have missed or have ignored. I value that, even when it arrives mixed with personal abuse, denunciations, profanity, and character assassinations. In response to your comment on the 60 kHz thread, I have done some spice simulation, mostly to estimate the Q of the antenna. I would be happy to post some info if you ask about it there. A new WWVB shielded magnetic loop is certainly on my agenda and I do plan to ask questions. However, I'll probably do it on the Time-Nuts mailing list, which has more RF people. Incidentally, I don't believe using a high impedance loop and amp are good ideas. While there are benefits, my experiences from the marine radio biz convinced me that high voltage is an invitation to problems from condensation, salt fog, and PCB leakage. In other words, it works on the bench, but craps out in the field. I'll probably end up with a large high Q loop, and a separate low-Z coupling loop (i.e. a step down xformer). ok, back to work... -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Now, if I could only fix my crappy arithmetic. Try this... :-) From: "G \"Guglielmo\" Evans G4SDW" Newsgroups: uk.radio.amateur Subject: Difficulty with maths? Date: Sun, 29 Jul 2007 12:47:45 +0100 Organization: Aioe.org NNTP Server Lines: 115 Message-ID: NNTP-Posting-Host: Z3IpgFh83JnnDIiU15n1gQ.user.aioe.org X-Complaints-To: X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2900.3138 X-RFC2646: Format=Flowed; Original X-Newsreader: Microsoft Outlook Express 6.00.2900.3138 X-Priority: 3 X-MSMail-Priority: Normal For those who claim an interest going back several years, (in one case 50 years!) and who have still not yet managed the M3/CB Fools' Licence hurdle that is set for 6-year-olds, here is Lesson 1 of a maths lecture course that I prepared some years ago. Practising school teachers who say that maths is hard should also start here. -----ooooo----- Copyright (C) 1999 G.A.Evans All Rights Reserved. So, you're a CBer and you want a Ham Radio licence? Good on you. Well, let's consider the differences..... CB is a social facility for those with no technical qualification nor competence. You must use type- approved equipment which you are NOT allowed to modify. You are restricted to one band, and to a very low output power. (More power, in fact, than your GSM phone, but still very low) Ham Radio is related, but not closely. Ham Radio is also a social facility, but with a difference. You are allowed to construct your own transmitting gear and use it on a multitude of bands, and at very high powers. With such privileges comes responsibility. You must demonstrate that you have a minimum of technical know-how, and for this purpose you must pass an examination, The Radio Amateur's Examination. This is not a difficult examination, It is easier than a GCSE, and when you consider that youngsters doing their GCSE's study and pass 10 at a time, then the RAE on it's own is a simple matter. To indulge in this technical activity, you must enjoy solving puzzles. You must thrive on finding out how things work and inventing things for yourself. If this doesn't describe you, then perhaps Ham Radio is not for you? Now, you will need a jargon to discuss and explain your new-found technical excitement. As a CBer, you may have said things like, "You're showing five cherries". All very amusing, but hardly technical. As a Radio Ham you will be expected to use and understand such phrases as, "S9 plus 20 dB". The jargon that you will use is known as "Mathematics". Now, "Hold On!", I hear you gasp, you were hopeless at mathematics (or, "Maths") at school. Well, let me let you into a secret. The problem with maths did not lie with you, but with the incompetence of your teachers. Maths is really quite straightforward, and the knowledge you need is no more than that which school children of 12 possess. You're not going to tell me that a child of 12 is better than you? Of course not! That's all very well and glib, but it cannot be denied that some of you have found maths to be difficult, and based upon the scorn heaped upon you by your incompetent teachers, some of you will have formed mental blocks that prevent you from making any progress. Well, what I am going to do, is to prepare some elementary lessons for you, which you can do in the privacy of your own home, where no-one will look over your shoulder or laugh at you. How am I going to do this when you already have a mental block? Well, what I will do is take you right back to square one, right back to where you were before you got that block, when you were perhaps five years old, and there was absolutely no difference between you and the other pupils in the playground, and bring you on in a spirit of confidence. (You may find the first lessons to be trivial, but please bear with me. The principles laid down will assist you throughout the course). The first, and most important thing which I will stress time and time again is this.......quite often you will come across some new maths which confuses you, but which more often than not, is a new way of writing down SOMETHING WHICH YOU ALREADY KNOW, something which is a shorthand to make life easy. -----OOOOO----- So, let's make a very easy start, illustrating this principle. Let us suppose that we are counting eggs, and if you'll pardon the weak pun, let's count "X's". X; one, obviously. XX; two, XXX; three, XXXXXXXXXX XXXXXXXXXX XXXXXXXXXX XXXXXXXXXX XXXXXXXXXX XXXXXXXXXX XXXXXXXXXX XXXXXXXXXX XXXXXXXXXX XXXXXXXXXX XXXXXXXXXX XXXXXXXXXX XXX; One Hundred and Twenty Three! So, here is that first and most important principle... instead of having that tedious way of counting, we use a shorthand... "1", "2", "3" and "123". Now, as I said, this isn't any new or clever maths, IT'S JUST AN EASY WAY OF WRITING DOWN SOMETHING WHICH YOU ALREADY KNOW. Right, that's enough for an introduction. Yes, it's trivially simple, but then so is maths, as you will see in subsequent lessons. Who knows, in a short time you'll get that Ham Radio license! |

Same goes for Demon who have already cancelled Usenet as BT are about to do. UK ISP's seem to be dropping Usenet like a ton of ****, without advance warning of any worth, and maybe all within a very few weeks of they haven't already done it. It seems to me that maybe the recent rush of govt demands that they clean up the piracy uses of Usenet, combined with ever increasing surveillance of ordinary people means that the only cheap safe way for an ISP to avoid looking like it's antagonistic to the new secret-policing style of UK government is to drop, IMMEDIATELY, all subsystems that might make them look bad. There may be more innocent explanations, like Usenet going to the dogs generally, public perception genrally favouring forums on the web. Judging by the recent squabbles here that is not hard to exaplain. Recent;ly, one night, I say one silly thing ina post otherwise reasonable, and TWO people try to jump down my throat. For a fleeting moment I was daft enough to think it might be about me, but no, I just went silent, looked the next morning, and those two people were at each other for most of the night in my absence! Anyway, I won't be paying for Usenet, so I'll be out of those people's hair. I'll jump before I'm pushed. If I can get an ISP with decent web hosting for no greater cost than I am paying to BT now for a heavily capped service with no web host, and very soon, no Usenet, I'll go as soon as I can. It's been helpful to me to have access easily to some knowledgeable people willing to post thoughts rapidly, in direct response to things I ask, and I'll miss that. On the other hand, some of those people have pointed out that good texts usually get a better guide to someone wanting an answer, if not as immediately. Usually I just trawl the web and look for multiple sources before whittling down to the best that works for me. It looks like the net's good times are over, it's likely to get harder after being easy for about ten years. I'm not going to try to speculate about why, but I know that if Usenet is no longer possible without a lot of additional expense equivalent to a new utility service, then I'm out. |

There are a number of good free text group newsservers, such as Eternal September, and at least one paid-for one with a good reputation that only costs 10GBP a year (news.individual.net). So I hope we don't have to lose you. -- Percy Picacity |

So I hope we don't have to lose you. Thankyou. I will look into it. Two caveats though... The one free one I looked at so far isn't free if I want to post. The other is that the truly free ones may be a haunt of trolls, Eternal September is a namd I have read in contexts of posters naming some systems with a bad hit-rate for troll sources. Ideally I'll try to find a paid service that is cheap, quiet, likely to stay put for a long time, but I think my priority might best be that web hosting. I mentioned a phase mod synthesiser in various posts when I could indulge it the reference, and the editor on which the final product will be based is tested working on all Win32 now, so it's time I started looking for an ISP that can help me host it cheaply as part of main ISP provision to save costs. I suspect they won't have Usenet, but I'll look at your suggestion of news.individual.net, it may well be a lot better than what I saw last night.. |

The Germans also don't oblige the kinds of govt prying mentaility the Brisitsh seem willing to accept, along with Google intrusions and all the rest of it. I'll probably go with this one. Now, if I could find a web host that looks this good... Got to be UK based though. I'l askign Demon what they can offer, not yet heard back, but if you or anyone can offer some suggestions, please do. |

The main reason being it's a pain and $$$ for them to maintain usenet, and I suppose the cost and hassle is not worth it for them vs the fairly low amount of their users that actually use usenet. In other words it's mainly about money. Or at least here in the states. Comcast dropped it a few years ago. So I just use google groups, which I had for a backup. I've actually got used to google groups and actually prefer it to using a usenet server and a reader, which is T-bird in my case. It's easier and faster to read the posts, where I can see all in a thread with one click, without having to click through each post individually. I also see all old archived posts in a thread, like the one's Gmailers often reply to a decade or more after the original posts.. :| I don't know what it is that provokes Gmailers to reply to posts so old it's often a crapshoot if the OP is still alive or not, much less still active. :/ But if you some loon replying to a 15 year old post, it's almost certainly a Gmailer, which I don't use. Now I use aioe as a backup in case GG craps out, which they do every once in a while. aioe is free same as ES. BTW, I got my revenge on Comcast recently. I had triple play and movie channels which the price kept going up, up, up, and I got tired of having to renegotiate a new price every year, as I refused to pay their full bloated prices. So 3 months ago, I canceled everything but internet. My bill went from $165 a month to about $64 a month. It can be even cheaper if I dump their now $10 a month gateway modem, and buy my own, which I plan to do when I get around to it. It was $8 a month until 2 months ago.. :/ My speed is now slower from my previous appx 58 mbps, to my current 7.2 mbps, or 15 mbps if I go in the unsecured xfinity back door using my laptop and wi-fi, but even 7 mbps is fast enough for most of my uses. It's only been three months, and I've already saved over $300.. Will save over $1200 a year. That's what they get for provoking me with once a year greediness and price scheme mayhem, which drove me up the wall every fall. :+ |
