The notice said that Section 97.205 states that an uncoordinated repeater does not have the same right to use of the band as simplex operators or coordinated repeaters. The notice also warned that failure to comply could result in loss of license. If someone puts a repeater in the simplex band, I'd say the odds are it is not coordinated :-). James E.

I had forgotten all about it and I still do this and wasn't aware of it until I saw this posting. 1. When you first learn the alphabet, do billboards and road signs like STOP, YIELD, LEFT, RIGHT, DO NOT ENTER, CAUTION, FALLING ROCKS, PIG CROSSING, PEDESTRIAN CROSSING, RAILROAD XING, ... 2. When you get the numbers down, do license plates. You get random groups of letters and numbers, thus don't get stuck in a rut with the same thing over and over (unless you count random combos of 36 symbols of letters and numbers a rut). :-) If you think that you ever want to do mobile CW operation, put an oscillator (keyer with sidetone) and key/paddle in the car. NOW KIDS, if you do this, read all the articles ever written on mobile CW operation and practice safe driving first. If you can't do two things at once (like me and walking and chewing gum), then don't even think of doing this. :-) I can just see you explaining to the local police, lawyers, judges, insurance companies, and the jury what you were doing when the accident occurred. I was sending OH SHoot when it occurred. :-) Of course, if you commute with a group or in a train/bus, this will distract others and probably bug the heck outta them too. dit dit -- SIG Chuck Adams K5FO CP-60 adams@sgi.com ------------------------------ Date: Thu, 22 Sep 1994 12:37:49 GMT From: ihnp4.ucsd.edu!agate!howland.reston.ans.net!pipex!bt!bfsec!jmagee@network.ucsd.edu Subject: Queen's University of Belfast Radio Club To: info-hams@ucsd.edu Queen's University of Belfast Radio Club ======================================== The Queen's University of Belfast Radio Club is a club for both students and staff of Queen's University of Belfast. It meets every Tuesday night at 37 Fitzwilliam Street from 7:30pm to late. The QUB Radio Club's activities range from Amateur radio to computing and all manner of electronics. No matter what your departments or how non-technical your background QUB Radio Club has something to interest YOU. Amateur Radio ------------- The club has range of radio equipment covering all available frequency bands from 160m (shortwave) up to 23cm (microwave). We have facilities for the transmission of speech, morse code, television and computer data. Also available is equipment for reception of weather data from polar orbital satellites. Our equipment, substantial technical library and the expertise of our many associate members are available to all our members. Contests- are you tough enough to carry a generator and four radio stations up a mountain and then operate those radio stations continuously for 24 hours? Computing --------- We have computers ranging from our BBC microcomputer through our two Commodore Amigas (including a 4000), PC and three DEC PDP-11 minicomputers to a DEC VAX 11/725 and two DEC VAX 11/750s. These machines are used by our radio network for data communications and for our programming courses and competitions. The details of the first competition will be available soon. We also intend to run a C programming course. We have also in the past entered a competition, which was sponsered by BT, to design a computer network and we won the first price of 3000 pounds beating a number of University departments. Electronics ----------- The electronic skills within the Club pervade all our activities. We convert commercial radio equipment to Amateur frequency bands and also maintain, repair and interface our computer equipment. We construct such devices as may be required from time to time. To join the club come to 37 Fitzwilliam Street on a Tuesday night or join the club at a discounted rate at the Fresher's Bazar in the Students Union on Friday 30th September.

We found several homes which were just perfect in everyway, HOWEVER they had this antenna deed restriction attached. After 8 months of looking and looking we finally found a older home in a upscale part of the city that DOES NOT have any antenna deed restrictions. I guess the moral to my story is, it all depends on whats more important to you. Sometimes you can't have everything, you have to bend, give and take. In my case, being the hard-core ham that I am, no antenna deed restrictions were more important then a swimming pool. I'm also very lucky to have a wife that understands me (and ham radio).

If amateurs would only visit the occasional new housing tract and invest a few hours in acting like a well heeled punter, and then walk out because of the clauses...... Expressing interest in all the expensive options helps - builders make particularly high profits on the optional bits..... I once bought a car with real, live cash. I took along a few percent less than they would probably accept, in a cardboard box. Took it out, wad at a time, counting it. Oh dear! not quite enough, I'll either have to save a little more, or go for the other brand. The salesman's nerve just wasn't up to the sight of the money going BACK into the box. House builders don't really care about these clauses, they just think that they help sales in some circumstances, all we have to do is highlight that they also lose sales in some circumstances and we can reverse the trend.

Do not repost this to the internet. You will be flamed if you do because of the length and you don't want that. Also, let's not use up bandwidth for flamewars etc., just email to me direct and do not, i repeat, do not post your values to this group. I'm sure they are not interested at this time and we both will get flamed big time. I'm going to take enough flak as it is. :-) If you don't know how to use your mailer on your system, then print this off and mail to me at the address listed within. I'll write "the" book on CW, but I need some help. Your help in fact. I'll credit everyone who contributes and I don't think you'll get a free copy of the book, but I'll try. This is going to be dependent upon the publisher. Obviously you'll need to write a chapter or more to be considered. Give me your resume if you want that much attention and I think you don't. :-) I'll take no royalities from the publisher for this work except to cover out of pocket expenses such as postage and phone charges. I'll do a FAQ if it hasn't already been done for just CW. Here's the idea. Book plus 3 CDs. Book has study guide, history of CW, world record holders, answers to the disks, Phillips-Adams chart for abbreviations, QSO formats and variations, and there will be several tests on the disks that if you copy and send in you get a certificate (but the ARRL already does this) along with tables of freqs and schedules for all the on the air practice you can find. Book will be typeset using LaTeX and 1200 dpi printer. Audio will be produced at 44.1K for CDs and 48K for DAT using DSP in a workstation with 2.5mS rise and fall times shaped to reduce or prevent "thumps" on make and break with no (absolutely no) background hiss, no crosstalk, and all that other crude you hear in other media. Variation in tone frequency to break the monotony. The CDs will have 6 hours of practice and tests using one channel of the stereo pair, thus the double time. I think that someone makes a cheap switch for attaching stereo headphones and getting one channel, R or L, out. I think this critter is used for books on tape (no wonder illiteracy is at an all time high). :-) Anyway, saves time and money. I'll send note to Wayne Green (CD wizard?) and see if he can give us a deal on CDs. :-) I know that we're talking about some serious money here in range of $50 or so for the whole kit and kaboodle (sp), but education is expensive no matter how you get it - K5FO. I can generate perfect CW at ANY speed. We'll shoot for Farnsworth spacing until 15 wpm and then it's regular code from there on up to 40 wpm. Then if there is enough interest to finance the project then we'll try for 60 wpm on another disk. Section of code samples for contest operations 1. SS 2. FD 3. CQWW 4. DX tests 5. Cracking a pileup for calls. Some one give me the history of Farnsworth. I have a reel-to-reel tape more than 25 years old that uses it, but it wasn't called anything back then. Did Farnsworth come along after that? I don't have a date for same. I'll take email listings of all books and materials that you personally own related to CW operation and/or learning. Anything that will help or that I may not have in my library. This whole project may flop due to the anti-code backlash and a lot of bad attitudes about code in general, but what the hell. Let's go for it. No flames please. This is a project, not a policy making decision. :-) Take that to rec.*.*.policy or whatever it's called.

On my amp, I have to turn >off the pre-amp when I'm in town because of the intermod. "Helical resonators" is a buzzword for a sharply tuned bandpass filter. The term was the subject of much awe when I first got licensed--like they had magical powers. Folks would get on two meters and brag, "MY radio has helical resonators in the front end". Sounds like hype, but yes, I've found that *well-designed* bandpass filters constructed of "helical resonators" are an effective weapon against letting out-of-band signals into your receiver where they can mix 'n match and work their way into your IF. But like all filter, they do induce some additional loss, so the preamp' is a good idea. Question is: what is the preamp's gain and noise figure? High gain with high noise is worthless... And yes, being able to kill the preamp' would be very desirable. Perhaps it's connected in parallel with the power amp, so that the switch either bypasses the amp/preamp' completely, or switches inline the amp/preamp'. The catalog didn't specify what the arrangement was. Incidentally, I took advantage of RS' current sale on the HTX-202 and picked one up for a spare radio to keep here at work. I must say that while it's larger compared to other available radios on the market, IMHO it's offers good performance/features for the buck. I'll still use my Yaesu FT-530 and FT-73R, but the HTX-202 looks like it'll be a good secondary radio to have around, and it didn't cost nearly as much as any of my newer HT's either. 73's, Collier Chun NM7B NM7B/R ------------------------------ End of Info-Hams Digest V94 #1053 ******************************
