Editorial

As promised here�s another newsletter � I still hope to produce three issues a year,provided I have enough material to fill each one (hint hint).

The rally on the 5th April was a great success, with many of you making their way tothe new venue. Thanks to Daryl G0ANV for once again operating the talk-in. However,it should be pointed out that helpers were in very short supply on the day, with thecommittee members and their families rushing around to get everything organised. Ifwe are to continue putting on an event of this size in future, it will be necessary forsome members to volunteer their services on the day; otherwise regular features likethe auction will be put in jeopardy. Without some help from you the members, thewhole future of the CRG rally could be in doubt.

Although this is a wireless-based newsletter, in this issue I have taken the liberty ofincluding a couple of short articles oriented towards computer users. One is a verybasic introduction to the Internet, and some of the sites aimed at the Radio Amateur.Whatever you may think about computers invading our lives, they�re here to stay, sowe might as well make use of them! The other article was in fact sent to me via theInternet, in response to our mention in the VHF/UHF column of RadCom. It givesfood for thought, especially now that more and more people are using computer loggingprograms.

If you have strong feelings about the above, or any other aspect of the CRG, why notdrop me a line, and I�ll include (printable) messages in a future issue. I can�t promisea prize for the �star letter�, but you never know!

Now a date for your diary. The AGM this year will be at Stow-cum-Quy Village Hallonce again, and the date has been set for the 18th November. This is your chance tohave a say in the running of the repeaters, so please try and make it if you can.

I�d like to finish on a personal note of sadness. Brian Charge (G3WQF) passed awayearly in July at the untimely age of 58. He was a good friend, who was always willingto help out another amateur, especially with aerial problems. I�m sure he will be greatlymissed by all who had the pleasure of knowing him.

That�s enough from me for now, I�d just like to thank you all for your support for thenewsletter � I hope you enjoy reading it as much as I do preparing it.

A Common Date/Time Standard for Amateur Radio:

Ian Gilpin, G1SMD (QTHR).

This brief article is to spread the word on a proposal connected with therepresentation of Date and Time in Amateur Radio.

We write times using �hh:mm:ss� or �hh:mm�. Imagine the chaos if somecountries used �ss:mm:hh�, others �mm:ss:hh�. We now use the 24-hourformat rather than 12-hour am/pm. The use of Local Time can causeconfusion in an International activity such as Amateur Radio. We avoidthis by using the UTC Time Zone. All these methods are defined in anInternational Standard called ISO 8601.

For dates every country seems to do something different. The date �04/01/80' means �4th January� in Britain, but �April 1st� in America, leadingto problems in computer programs, on QSL cards, in email, and innewsletters. In a few years time we will have dates like �02/05/03' and�04/09/05' tocontend with.

ISO 8601 has a solution to these problems. The date is written usingthe full four digits for the year, with the order Year-Month-Day, and hashyphen separators. A leading Zero is used for �01� to �09�. In this way,a date cannot be confused with that written in any other format. Somepeople prefer to retain the Year-Month-Day ordering whilst writing themonth as a three letter abbreviation or out in full.

The date is written in any of three easily interchangeable ways: 1980-01-04 1980-Jan-04 1980-January-04.

The ISO standard has already been adopted as ANSI X3.30 in America.In Europe, the standard has been implemented as a �EuroNorm�. Underthe CEN regulations every member state is required to adopt this EN28601 standard (all of Western Europe, and most of Eastern Europe).

5

This format has been defined in Japan in the JIS X 0301-1992 standard.

ISO 8601 has been in use in Scandinavia, parts of East Europe, andmost of Asia for many years, and by astronomers for over 200 years.They realised, long ago, the advantage of working to a common standard,world-wide.

In recent times, IBM has promoted the ISO standard as part of the fixfor the �Year 2000 Problem� with computer systems. The �full� ISOformat solves this problem as well as the UK / US date ambiguity. DOSand Windows already have provision for the Year-Month-Day methodbuilt in, as have a number of Amateur Radio programs.

The Amateur Radio proposal recommends adoption of the ISO formatfor all facets of the Amateur Radio hobby: computer programs, logbooks, QSL cards, email and packet messages, Web Pages, band reports,newsletters, and so on.

The German magazine DUBUS has already adopted the new format,along with �CQ-TV� published by the BATC; as has the Meteor Scattersoftware by OH5IY, and the new EME programs by VK3UM. G3SEKis rewriting all his software to cope with the Year 2000 and to adopt theISO format. G0RUR is using it in his software in 1998. G3RUH hasused it for very many years. The ITU are using the ISO format on theirWeb Page at: <http://www.itu.int/> and in some of their documents;as are the BATC in their Web Pages.

This is the only Internationally agreed format, and I recommend its useto all Radio Amateurs. Use a 4-digit Year and the Year-Month-Day order.We all understand the time �22:44:59'. There should be no problemswith the date �1998-03-10�, whereas �10/03/98' will always have adifferent meaning across the two sides of the Atlantic. ISO 8601 replaces�dd/mm/yy� and �mm/dd/yy� with �yyyy-mm-dd�. Also note that Datesare written before Times in the standard.

The full proposal document was printed in DUBUS 1997-Q1 (Page 83to 85) and is available on Internet at: <http://www.kirsta.demon.co.uk/iso_8601.htm>. Copies have been circulated to RSGB, ARRL, IARUand so on.

More information on the Year 2000 and on ISO 8601 issues can befound at: <ftp://ftp.funet.fi/pub/ham/misc/g1smd.zip> along withinstructions for DOS and Windows to use the ISO format. Also includedis an extensive list of sources of further information from magazinesand on Internet.

There are articles on this subject in the last issue of 1997 and/or firstissue of 1998 of CQ-TV (BATC), Oscar News (AMSAT-UK), Datacom(BARTG), and Monitor (ISWL).

A short general description of the ISO 8601 Date Format can be foundat: <http://shell.ihug.co.nz/~hermetic/cal_stud/formats.htm>.

There are also several files on this subject available from the GB7PFT�CLIVE� server, and by the �reqfil� service from several other AX.25Packet BBS systems in the UK.

The British Amateur Television Club (BATC) have also recently adoptedthis proposal. They now have a �Date And Time� document on theirWeb Pages located at: <http://www.batc.org.uk/> all about this subject.There is also information in the BATC �CQ-TV� magazine, in issues180, 181 and 184 (Nov 1998); copies of which can also be downloadedfrom the BATC Web Site.

The ISO 8601 standard even gets a mention in main-stream computermagazines, such as in Byte (US/Europe), 1997-Jul, Page 89 and inComputer Shopper (UK), 1998-Jun, Page 616.

My own Web Page is at: <http://ourworld.compuserve.com/homepages/dstrange/y2k.htm> and my email address is: <g1smd@amsat.org>.

Internet Basics and Amateur Radio

Terry Bickell G0UIOIntroduction

Firstly, I know there are many amateurs who have never used a computerand don�t intend to start now. If you fall into this category then you maynot want to read any further. On the other hand, if you can bring yourselfto read on, I hope to explain what all the fuss is about concerning the�World Wide Web�, and how it can be of use to us as amateur radioenthusiasts, without becoming more technical than necessary.

In simple terms, the Internet is simply a method of connecting computerstogether to share information as widely and easily as possible. Anysubject you can possibly think of (and a lot more besides) can be foundhere at the press of a few keys and with a little bit of thought. Lettersand messages can be sent world-wide almost instantly, and for lessthan the price of a first-class stamp.

Equipment required

As you are probably aware, in order to access the Internet you needsome form of computer, and it�s fair to say that the more up-to-date thisis the easier and faster your use of the Internet will be. The other necessityis a modem (modulator/demodulator), which converts the digitalcomputer data for use on an analogue telephone line. In terms of cost,these items may run to well over £1000, but here in the Cambridge areathere is a service (CamNet) which claims to be accessible using a simpleterminal program running on an older computer such as the BBCMicrocomputer. These may be picked up at a rally for as little as tenpounds, or a little more with a monitor. A decent modem can be boughtfor around fifty pounds, or less if communications speed is not of primeimportance. A system like this, though, is really only useful for sendingand receiving electronic mail. To search (or �browse�) the Internet amore powerful computer such as a PC is required. The only other thing

12

13

14

you need (apart from a telephone line) is an account with an InternetService Provider, or ISP. An ISP acts as a gateway between you and theInternet, finding the information you request and delivering it to yourdesktop. Internet accounts vary greatly in price, depending largely onthe features you require, and other factors such as 24-hour telephonesupport. For example, my CamNet account costs only £20 per year, andgives me full Electronic Mail and �Web Space� to store information Iwant to make available to other users. However, it has only limitedaccess to the whole Internet network, and for this I use another account(Infotrade) which costs slightly more, at £68 per year � still good valueto me for the time and money it saves. Other ISP�s, such as Demon andPipex cost more, around £15 per month, but offer other features. Itshould be noted that all the more expensive ISP�s provide local callaccess1, wherever you are in the UK. Some (like Pipex and CamNet)have Cable numbers, so if you are already a Cable subscriber, you saveon line charges.

Amateur Radio Sites

Information on the Internet is stored on �sites�, which can be dedicatedto any subject the author chooses. Obviously there are a great manyrelating to Amateur Radio, and I don�t intend to go into too much detailhere, simply to mention a few of general interest. These are given towardsthe end of this article. Most of the most popular ones have links toothers, you simply have to find your way around them, noting thosethat you find most useful. As an example, when I was asked to producethis newsletter, I thought about a radio-related photograph on the frontcover. A few minutes on the net produced several nice shots of aerialarrays, one of which is shown on the next page (I had to get some radioin somehow).

RSGB members will have noticed a new column appearing since theApril 1998 issue of RadCom called �WWW�. This is written by AndyGayne (G7KPF)2. Andy has an extremely good radio-related web page,with links to other sites such as the RSGB and ARRL ones. A list of

15

addresses of the sites mentionedis given at the end of this article,as well as contact details for someISP�s.

One site I find useful is the QRZdatabase site. Here you can findQSL information contained on theQRZ CD-ROM � handy forconfirming addresses, etc. Notonly that, but it is possible toupload a scanned image of yourQSL card with your details, andthis will be included on the next edition of the CD. I uploaded a copy ofmy card, and the next thing I knew I received a letter from a CanadianAmateur asking me to send him a photograph of my cat! A GermanAmateur staying locally visited me one evening, and took great pleasurein showing me sites specialising in his favourite aspect of the hobby,Moonbounce (EME), complete with lots of interesting photographs (seeabove).

Most major Amateur Radio dealers in the UK, such as Martin Lynch,have web sites where you can check out their stock and in some casesplace a credit card order. Similarly all the radio manufacturers alsomaintain a presence on the web, where it is possible to get informationon new and existing products and to download computer software tocontrol Amateur equipment.

Finally, the Internet has a large number of News Groups, which arediscussion forums for various special interest groups. The one most ofus will be interested in is uk.radio.amateur, covering aspects of amateurradio in this country including items for sale and technical subjects forexample. I also subscribe to uk.media.radio.archers, the subject of whichshould be obvious to anyone who knows me!

Try before you Buy

If what you have read interests you, but you want to have a look foryourself before taking the plunge, then there are a number of places inCambridge (for example) where Internet access is free to all. Perhapsthe most well known one is the Central Lending Library in the LionYard. Here there are several terminals for public use, although therecan be quite a queue near exam time! Another place I have often usedin the past (as an unwilling visitor) is at Addenbrookes Hospital, wherethere is an Internet link at the CAB office in the main concourse. Quitea good way of passing the time while waiting for that delayed out-patient appointment� There is also the Cyber Café on Mill Road, whereit is also possible to sign up for the CamNet service. If you find yourselfgoing to one of these places, why not take this newsletter along withyou and have a play � you may find it interesting enough to want to signup yourself.

Conclusion

I very much hope this short(ish) article has been of interest to you,although I have only been able to scratch the surface of what is possible.To go into the Internet in greater depth would require much more space,and is not really suitable for a radio-based newsletter such as this.However, you may want to buy one of the many Internet-basedmagazines available to investigate further, and if you know anyone withan Internet account why not ask them to give you a demonstration �I�m sure you�ll be impressed. Personally I find it an invaluable aid, inboth my computer and radio hobbies, and wonder how I ever managedwithout it.

Budget ISP�s

Infotrade £68 per year. Part of the Mitsubishi organisation, theyprovide a fast service (compared to some larger ISP�s) but do notnormally provide web space. Multiple Email addresses can be addedfor a small fee. Telephone for free software CD and one month freetrial. No newsgroups are supported directly, but it is simple to go throughanother ISP to facilitate this (I use news.cam.net.uk, which works fineand you don�t need an account with CamNet). Tel: (0800) 226600

CamNet £20 per year. Includes 1MB web space and alternative Emailaddress. However, access to the WWW is limited, although thenewsgroups are comprehensive. Can be used with simple terminalsoftware such as a BBC computer, or an older PC. Intended for users inCambridge and the immediate surrounding area, the home pages havea strong local content (City council, shops, etc). Cambridge Cablenumber for cheaper telephone charges. Tel: Cambridge (01223) 500600

Cambs.Net Not to be confused with the above, this service providesfull access to the Internet and has a wealth of local information on itshome pages as well as all News Groups. Alternative Email addresses(of the form g9xyz@�) are available. I have negotiated a deal withCambs.Net for CRG members, giving us a discount of £10 on theirnormal rate from £59.99 to £49.99 per year. (or £4.99 per month), whichmay reduce further in time. Free software is supplied on CD. Tel: Ely

As there are literally hundreds of different ISP�s in the UK, I obviouslycan�t produce a detailed list. However, of the three above I have personalexperience of the first two and am in discussions with the last, whoseem very helpful (and are even �radio-aware� � hence the discount). Ifyou have money to spend and decide to make serious use of the Internet,you may want to look at one of the bigger ISP�s, such as Pipex or Demon,but then you�d be looking at £15 minimum per month, which may be alittle hard to justify to the boss�

PS Those of you who already know a little about the Internet may wonderwhy I haven�t mentioned the new 56K modem speed. The reason forthis is that the V90 �official� standard for this speed is only just beingintroduced, and it remains to be seen how long it takes for the ISP�s tocatch up. In the meantime, I have assumed that all ISP�s will support33.6K modems using the older standard.

1 CamNet and Cambs.Net are exceptions to this, being intended for local users.

If At First you don�t Succeed�

By Sheila M1CKO

Some people may think I should have given up, and many would havedone. But my determination to become a Radio Amateur spurred me on

This is my story

Going back to 1981 Citizens Band Radio was the craze. I remembersitting in my comfy chair for hours chatting away, �14 for a copy,come back good buddy, what is your handle?�. We had the Viking,Mongrel, Warrior, and myself � Night-Nurse; and many more. Somehave gone on to be radio amateurs. I didn�t know anything aboutwatts, resistance or even how to put on a plug, I only knew how tokey a microphone - little did I know as the years went on I wouldlearn.

We moved house in 1987. Down came the aerial and away went theCB radio. In 1989 we moved to our present home, and good OldFaithful came out again, but by that time the people I used to talk tohad gone and the channels were full of bad language and music. In1994 my daughter�s boyfriend (who is now her husband), told mehe was going on an Amateur Radio course. My interest was instantlyaroused, but it was no good me doing it as I was too dim - the onlything I ever achieved was passing my driving test (and that wasmany years ago). And for me to go on a RAE course would makeme look an idiot as I wouldn�t have a clue what they were talkingabout, but I decided to buy and borrow some books anyway, and setabout reading and learning as much as I could. It was in May 1995that I took and failed my first exam and back to the books I went -I thought to myself �lots of people fail first time�.

The next Rae exam I took was Dec 1995 once again I failed - I wasdisappointed but was not going to give up. Also in 1995/6 I went on

20

a novice course and thanks to John Bonner G0GKP I passed withcredits and how proud I was with my new call sign 2E1FFU. Bythen I had a 2m & 70cm handheld and I spent hours listening andlearning in May 1996.

Back I went to try the exam again. Two months latter the failuredropped through my door, but my husband Colin who had also beenstudying for the Rae had passed, which made me more determinedthan ever.

Dec 1996 I tried the exam yet again AND MANAGED TO PASSPAPER ONE! At least I was half way there, or so I thought, but itwas at that time the RSGB decided Dec 1997 was the last time theywere going to have two papers in the exam. So if I didn�t pass papertwo by Dec 1997 my paper one would be void and I would have tostart all over again. So in May 1997 back I went to sit paper two (bythis time it was first name terms and getting close to getting myown car parking space). Two months later this little envelopedropped through my door and I knew at once it was a failure.

By this time the purse strings were squeaking, as it�s not cheap totake these exams, but my determination and a remark that was madeto me (which I won�t mention) spurred me on once more. So inDecember 1997 back in the exam room I went (I was the only onetaking the exam - usually there has to be five or more people butthey said they would make an exception. My gratitude to CambridgeRegional College). I then had the long wait� On WednesdayJanuary 14 a big brown envelope dropped through my door. A PASS!

I now hold the callsigns 2E1FFU & M1CKO, which I�m very proudof. You may laugh that it�s taken me three years to achieve what Iwanted but at least I didn�t give up like so many would have done.Between all this I�ve also learnt how to use a computer. I have oldfaithful in the shack now and still on the odd occasion pick up themicrophone. So come on you lot out there, never put off �til

21

tomorrow what you can do today; never say �I wish I had� whenyou can make your wishes come true. Whatever your age, you neverknow what you can achieve until you try. And does it really matterhow long it takes?

I wonder what I will do next� Watch this space!

Bathtime in Aden

Terry Chapman G3PTQ

Sometime in the early eighties, another G3, and I working for the local�Establishment� were sent to Aden (now the PDRY). The equipment tobe installed was to be operated from a DC battery supply.

Now Aden had deteriorated somewhat since the British were kickedout in the seventies meaning that virtually everything had to be imported.The large batteries could be sent by air but the carriers would not acceptthem with acid for safety reasons. They also could not accept acid inbottles either. They would accept it in powder form however, but wewould have to mix it up with distilled water on site.

This powder and emptied batteries arrived eventually (manana, mananaetc) after the usual paperwork delays. As we would have somethinglike 20 gallons of battery acid when mixed, we left the local engineersto find a suitable container to mix it in. They came up with a domesticenamelled bath complete with overhead shower. This was an operationalbath in their wash room.

To make this useable (and safer!) they put a plastic bag over the showerhead and taps to stop explosive drips into the acid. The problem wouldbe the plughole I said. No problem, they said and promptly brought ina bucket of quick drying cement and sealed it up. A few hours later allthe acid was mixed, and an assortment of utensils were used to bail outthe acid and fill the batteries. Whether the bath was ever used again Idon�t know but how would a job like that have been tackled in thiscountry?
