THE THREE POINTS OF THE KENWOOD TRIANGLE REPRESENT ADVANCED TECHNOLOGY, QUALITY AND STYLE

AlP/ATT

NB

Ifir

If Kenwood's TS -50S wasn't the

world's smallest H.F. transceiver, it

would still be a mighty impressive

piece of equipment.

Its maximum output of 100W,

combined with 100 memory

channels, gives its operators a

versatility that other, bulkier H.F.

transceivers struggle to match.

menu system and user-friendly

"fuzzy logic" Direct Digital

Synthesiser makes it simple to

operate on the move. And a host of

features, from Advanced Intercept

Point to switchable AGC circuit,

means that although the TS -50S is

small, its performance is a big

talking point.

Your local Kenwood specialist

dealer has the full technical story.

So all that remains to add is the

price: around £1000.

After all, the Kenwood TS -50S

may be the world's smallest H.F.

transceiver. But you don't need

the world's biggest bank account

to own one.

8 Practical Wireless, June 1994

When I was offered theopportunity byG3XFD to write the`Keylines' editorial. Irealised that I had a

unique means of communicating theviews and aspirations of the RadioSociety of Great Britain to a differentsection of the amateur community.

Although the RSGB represents over50% of the active licensed amateurs andshort wave listeners within the UK. weare always anxious to take such anopportunity to reach non-members andgroups that have an interest in one of themany facets of amateur radio.

It is especially pleasing to be able touse PIV as a vehicle for this since thepaths of G3XFD and myself havecrossed in the past as we were bothemployed by the IndependentBroadcasting Authority at theirWinchester Headquarters. I continue towork for the successor to the IBA'sengineering division (NationalTranscommunications Ltd.) whilst Robhas returned to full time journalism.

Why Support The RSGB?

So why support the RSGB? Primarilyfor two reasons. The RSGB is acceptedwithin the International Amateur RadioUnion as the organisation that representsthe views of Radio Amateurs within theUK. And it is the organisation that dis-cusses with our licensing authority. TheRadiocommunications Agency, allaspects of the privileges that are grantedin the UK.

I: The IARU represents the interestsof Radio Amateurs world-wide. TheIARU specialists represents us at WorldAdministrative Radio Conferences andmajor conferences dealing with allaspects of the spectrum. The IARU hasensured that delegates to these confer-ences are aware of the contribution thatthe Amateur Service has made toEmergency Communications and gener-ated many specialist papers setting outthe technical parameters affecting theallocations that we already enjoy andgiving reasoned arguments why thesemust he retained or expanded.

And who pays to support theseVOLUNTEERS? - the National Society

accepted by IARL! - the RSGB. TheRSGB contributes on behalf of everylicensed members to protect our alloca-tion for EVERYONE.

You can also help to protect thebands you use - join the RSGB.

2: The Amateur Service in the UKis fortunate in having an administrationwhich appreciates that the work is car-ried out by AMATEURS.

The role of the RSGB is to placebefore that administration the views ofas many as possible of the licensed ama-teurs in the UK. In this area we appreci-ate the space that has been donated byPit for input by non-members of theRSGB.

The RSGB maintains a specialistcommittee structure. again of volun-teers. many of whom give a consider-able amount of time to the RSGB. It isfront this structure that proposals areformulated and submitted to the RA forthe benefit of all. It is also these com-mittees that monitor the whole area ofradio development so that the Societymembers are kept informed of trends.

How can you help to maintain thisservice? - join the RSGB!

What Else?

What else does the Society 'DO'? Itproduces a monthly magazine. RadioComnzunicati ons produces a wide rangeof technical hooks with price conces-sions to members. offers advice from thespecialist committees, runs the QSLbureau, operates GB2RS for general upto date news, promotes the Novicescheme. organises and adjudicates con-tests across the whole spectrum.

In one phrase: the Society 'Looksafter the interest of ALL interested inAmateur Radio'.

I believe therefore, that all UK ama-teurs (licensed or not) should supportthe SoCiety. As a member, it is worthmaking a positive commitment to con-tinue to support the Society. and as anon-member. by joining either under thenormal methods or by taking advantageof the three month trial offer available ifyou use the Direct Debit method of pay-ment. Finally. we welcome commitment- input illustrates interest - and theRSGB goes to a lot of trouble to gener-ate interest.

I hope that if you are not already amember, you will take advantage of thespecial offer. I look forward to hearingfrom you.

RE

Europe For QRP Weekend - Reply

Dear SirIn reply to Mr W. FarrarG3ESP in the April issueof PW, I think he is cor-rect in part. I should likehim to try and prove hisassumption on 144 or430MHz, on a regularbasis. It is not too unusu-al to have S2 or S3 ofnoise evident on theabove bands. On occa-sions we, in the Fort

William area, have thisunpleasant experience.

Further to the aboveon VHF National FieldDay 1993, my groupusing 100W to a 17 -ele-ment Yagi on 144MHzhad reports of 'barelyaudible' through suchnoise. So, instead ofgoing down in e.r.p. weshall go much higher,indeed had we reduced

power we would havebeen as well to use theRoyal Mail!

Can I suggest he trythe Practical WirelessVHF Low Power Contest?And then compare hisresults with the top tenVHF Field Day entrants.R. Johnstone GM1YGVInverness-shire

Insurance

Dear SirAs a full time insurance intermediary I read with some interest the article byJim Stroud in the March 1994 PW. Having spoken to those of my clients whoare radio amateurs, I think that there are two issues here.

The first issue is whether or not motor insurers regard the installation of atransceiver as a modification. Most of the insurers that I have spoken to onthis issue seem not to have any problem with this, although I would suggestthat any reader taking out motor insurance checks with his broker or the com-pany as to whether or not problems exist. I would suggest that anyone insur-ing through a Lloyds syndicate be particularly careful about this.

The second relates to cover on the equipment itself, as Jim Stroud sug-gests, cover under a motor policy is likely to be limited. It is, after all, theintention of motor insurers to cover standard risks at a standard price andcover on amateur radio equipment installed in cars is not standard. It is alsoquite likely that much of the equipment installed is put in on either a semi-permanent or temporary basis, for example using locking slide mounts. Manyamateurs may well use their mobile rig in the house, up a mountain or take itaway with them on holiday.

As a result of this, I would like to suggest that readers wishing to insuretheir equipment, insure it as extensions to their household contents policies.Most insurers will do this, although it is important to explain to them exactlywhat your intentions are. This has the advantage that the equipment is cov-ered anywhere, the excess will be less and there will be of course be no lossof motor claim bonus, which, as Jim Stroud pointed out, is a very importantconsideration.P F. Rigg GOTVB, Lancashire

'Criminal' Operators?Dear SirReference PWApril news story 'Repeater GroupTrap Misusers'. So, this is what amateur radio iscoming to! Repeater Group's sending invoices tothe 'criminal' operators that have the bare facedcheek to exceed the two minutes time out, orworse still, don't contribute towards the 'electricbill'.

I thought amateur radio, to quote ARRL "is away of making new friends" through your hobby.Can Mr Colin Lansley inform me if GB3SN'saddress is the registered 'business address',because once invoices are issued to user's of arepeater, it then becomes a money earning con-cern which I am sure contravenes licence regula-tions. I would also like to know how many of hisrepeater group use packet or any other mailbox-es, and if so, do they contribute to their upkeep?

Sorry Colin, you have got it wrong. I think it'stime to get back to the real spirit of amateur radio.Repeaters have their place in the hobby, but don'texpect other radio amateurs to 'finance' yourequipment, other than on a voluntary basis anddon't try to be the policemen of the air waves orworse still 'REPEATER TRAFFIC WARDENS', last-ly, don't 'rip off' your fellow amateurs or youcould end up being a 'RADIO LEPER'. I can contin-ue my interest's in amateur radio without usingrepeaters, but not without replies to my CQ calls,can you Colin?R. Frettsome G4VVP1N, Nottingham

Editor's reply: Wow! It seems as if the PW'April Fool' spoof really worked this year!Quite a few readers seemed to fall for our1994 joke (despite the news story saying itstarted on April 1st!) and I received quite an'earbashing' from really upset visitors to thePicketts Lock show who thought thatGB3SN's keepers were being high-handed. Ithank those who recognised it as an AprilFool spoof and called us in the office to'pull our legs'. I cannot promise we won'ttry another devilish trick in 1995!

Direction FindingDear SirBefore becominglicensed I found yourmagazine a great sourceof information and inspi-ration. Now that I amlicensed I am finding itdifficult to pursue mychosen field of interest,namely direction finding.

The only book I havefound on d.f. equipmentis the ARRL Handbook,but none from the RSGBor just separate authors.

I found the ARRLbooks good but found itdifficult to copy the cir-cuits as many of theimportant components

were not available inEngland, I wasn't surewhat the best equivalentwas. Through sheer luck Icame in contact with anamateur who has built a144MHz d.f. unit whichuses Doppler shift to givean extremely accuratebearing. The said gentle-

man gave me a lot ofhelp in the constructionof my own unit. I wouldlike to know if there areany amateurs who sharemy interest in d.f. or anyclubs who cater for thissubject.G. Kinder G7PUTSurrey

Editor's reply: Wewould be like to hearjust how many readerswould be interested ind.f. operating. We willalso pass on any let-ters to G7PUT.

Getting Through The RAE

* * STAR LETTER * *No Projects For VHF

Dear SirI am writing in support of Bob G1WEX (April issue). The v.h.f.bands are neglected in PW, you only have to read it regularlyto see the truth of this. No projects for v.h.f. bands from a mag-azine with 'practical' on its cover, in small print and gettingsmaller!

It takes no effort and no skill to criticise, but surely oneissue a year wouldn't be too much to ask. The magazine is,after all, the same price to G7s and 2Els as it is to everyoneelse!

Secondly, your magazine is also read by many people whoare not amateurs but might like to be. For the benefit andencouragement of those people could the syllabus and approx-imate cost of the NRAE be printed, say twice a year. They can-not enquire on air can they?

On the plus side I subscribe to PW, so it can't be all bad.'Antenna Workshop' is my favourite and G3RJV is my hero!John Cartwright G7OBGDerby

Editor's reply: We will be doing another v.h.f. specialissue soon John. 'Antenna Workshop' will also be cov-ering more v.h.f. projects and you'll see more ofG3RJV's writing (including some in 'AntennaWorkshop'). I hope to make an announcement verysoon. Watch this space!

Restrictions OnSubscriptionsDear SirSome few years ago, as a pen-sioner, it became necessaryfor me to exercise financialrestrictions on subscriptions tonewspapers, magazines, etc.Regretfully, PW had to beincluded in the cancellations.

A request to the locallibrary to take out a subscrip-tion to PWwas rejected on thegrounds they too were onstrict budget control.Notwithstanding, enquirieswere made by them to themany other libraries inStaffordshire, resulting in theCannock Library transferringtheir copy of PW after use tothe Stone Library, especiallyfor my reading pleasure.

I have enjoyed this uniquearrangement for three yearsand as PWdoes not 'date', thearrangement is entirely satis-factory and will explain thesomewhat dilatory response toyour invitation in theDecember 1993 issue of PW toshare experience of PublicLibrary services. Hats off toStaffordshire County LibraryService in general and toStone and Cannock Librariesin particular!D. LongStaffordshire

Licence ProblemsDear SirAs the anniversary of my firstreceiving my 'A' licence was the14 November and I arranged topay the fee by direct debit to PostOffice Counters I was not expect-ing to receive a reminder, but Iwas most certainly surprised toreceive on the 29 December a redFinal Notice that payment had tobe received within 14 days ORELSE!

Without delay, I sent mycheque for £15 to the RLC asrequested. On 14 January mycheque was returned and I wasinformed that I had to re -apply fora licence. Sending original RAEpass and Morse test certificates.

Following two telephone callsto Subscription Services Ltd.,Bristol, I learnt that payment inNovember had been returned andthe computer listed me as nothaving paid, as my cheque wasreceived after 1 January when therules had been changed and a 30day warning rule had beenbrought in. I was told that I wasone of those who 'had beencaught out'.

I have received one or twocirculars from the RA all undatedwith unfranked envelopes which Ifound confusing, so I suppose itis my own silly fault. In the mean-while I understand that my appli-cation has gone to the bottom ofthe pile of new applications and Iam at present incommunicado!N. Bray GWOMOJGwynedd

Dear SirReference getting through the RAE. I noticed the recent correspon-dence in PWfrom readers who had problems in passing the RAE.

My studies for the RAE consisted mostly of reading just one book,Foundations of Wireless by M. G. Scroggie.

The author's style of writing is extremely clear and lucid andmakes electronics and wireless very understandable, (indeed the bookitself serves as a classic example of a good textbook, regardless of thesubject). I believe that Mr Scroggie edited the book from the time ofthe Second World War through to the last decade. He died only a fewyears ago when aged around 90.

I readily recommend this book to anyone struggling to understandelectronics and wireless in preparation for the RAE.

I took the RAE twenty years ago, after reading Foundations ofWireless. I did not find it too hard going (although the exam itself wasin a different form then and the range of topics has since changed).

I am now studying for a BSc. in Computer Science andManagement Studies. As a final tribute to this book, several of my fel-low students found it of great use when they encountered electronictheory and semiconductors for the first time.lan Brothwell G4EANNottingham

Editor's comment: Fortunately lan, copies of Foundations ofWireless regularly appear on bookstalls and at car boot sales (Ibought two copies last year myself) and they still provide anexcellent reference source. Another series of books commonlyavailable secondhand (which I thoroughly recommend) are the'Common Core' Basic Electricity, Basic Electronics, BasicTelevision, etc. Although out of print, many libraries stillstock the hard back versions. They provide excellent, easy -to -read structured basic teaching courses which in my opinionhave never been bettered. I bought three sets of BasicElectricity for a school club last year...for an outlay of only £3a set!

Dear SirI would like to add a few lines to your correspondence on the RAE andthe tuition available.

In 1960 I started an evening class course in preparation for theRAE. After a few weeks I realised that 95% of the students had electri-cal backgrounds.

As one who had no knowledge of radio or electricity I was com-pletely out my depth and dropped the whole idea. During the follow-ing 30 years, my interest in radio continued, but I only participated asa listener.

In 1992 having retired, I again considered the RAE and enrolled asa student with the Rapid Results College. I thoroughly enjoyed everylesson and my tutor G8PG was first class.

I sat the examination in 1993 and was successful in both papers. Iwould recommend the RAE to anyone and can honestly say therewasn't one question on the papers that hadn't been covered on theRAE course.Doug MayhillWest Glamorgan

Dear SirI'm writing in response to Mr T. M. Pirre's unfair criticisms in the AprilPW of both the RSGB and the Rapid Results College.

I was not able to attend the RAE classes given by our local cluband so I decided to use the Rapid Results College course.

After studying at home and with the excellent tutorial supportgiven then by Gus G8PG, I was able to confidently sit the RAE after sixmonths.

My sole sources of information were from the Rapid ResultsCollege and the RSGB's Radio Amateurs' Examination Manual. Theexcellent content of the information provided by both these sources isobviously regularly updated and more then adequate. After sixmonths of hard slog I was able to sit the RAE and achieved a Creditand Distinction in the papers. I will also add that I have no connectionwith either the electronics or radio industry and I started my studyfrom the basics.

The RAE is far from being a 'doddle' and one only gets out whatone puts in. Frankly, Mr Pirrie's letter smacks of sour grapes.R. J. Kent GOROS, Oxon

By now a number of youwill have received yourcopies of JVFAX, the popu-lar FAX and SSTV packagefor the IBM PC. I think a fewoperational tips may comein handy.

One of the first areas ofconfusion seems to beselecting the appropriatesettings for the demodula-tor. As most people useone of the simple cornpara-tor interfaces, you need toselect the Configurationscreen and set-up as fol-lows:

Demodulator: 8 bitscomparator addr 02F8IRQ 3

This is the correct set-upfor a computer with theinterface connected toCOM 2. If you are using adifferent COM port you willneed to adjust the addr andIRQ as follows:

COM: addr IRQ1 03F8 42 02F8 33 03E8 44 02E8 3The next problem which

faces listeners is decidingon the correct tuning point.Whilst the JVFAX bargraphdisplay is very good thecorrect tuning point is notvery clear.

The answer is to adjustyour receiver so that thesignal peak sits just overthe right hand end of thedisplay. However, beforedoing this you must checkthat the deviation is cor-rectly set for 400Hz on h.fand 150Hz on i.f.

Out Of SpaceUnless you have a verylarge hard disk you willprobably find you start run-ning out of disk space veryquickly. This is because

Elaine Richards G4LFM unravels JVFAX confusion, provides theanswers to her technical teaser and has advice on QSLing.

Elaine Richards G4LFM, PO Box 1863,Ringwood, Hants BH24 3XD.

many weather chart filescan be around 1.2Mb each.

There are a few ways toovercome the space prob-lem. The most obvious is topractice good file manage-ment and to make sure youdelete all but the files youreally want to keep.

You can also save a lotof space by using the Zoomfacility from the Show andSave menu. This enablesyou to save just selectedportions of images (don'tforget to delete the originalafterwards!).

If you mainly view yourreceived images on thescreen you can save somedisk space by changing theresolution of the receivedimage. This is done byselecting the mode editorfollowed by the requiredmode.

A look at the figure for120/576 FAX shows that theimages are normallyreceived with a line resolu-tion of 1810. This can easilybe reduced to around 800for on -screen viewing.

Another space saver ifyou want to receive weath-er charts is to set the greysoption to two. This elimi-nates the grey scale infor-mation which has a signifi-cant effect on the size ofthe saved image.

That about finishes thisupdate, but if you have anyquestions about JVFAXplease write and let meknow. If you would like acopy of JVFAX, then send aformatted disk, a stickyaddress label and threefirst or second class stamps

to the address at the headof the column.

Technical TeaserAnswerIf you take a look at Fig. 1,you will see a reminder ofthe circuit printed in lastmonth's 'Novice Natter'.The question I posed was

for you to explain why thecircuit wouldn't work.

As I hinted last month,the answer lies in the biasvoltage that's neededbetween the base and emit-ter of a transistor before itwill start to conduct. FromFig. 1, you can see that thevoltage on the base of thefirst transistor is set by thepotential divider R1 and R2.The current through thisdivider can be calculated as

9/(2700+2701= 0.003A or 3mA.

+9V

©

Fig. 1: Technical teasercircuit.

OV

From this you cancalculate the voltageat the base of the firsttransistor as

270 x 0.003 = 0.81V.

14 Practical Wireless, June 1994

Now the first two transis-tors are connected togetherin a special way that'sknown as a Darlington pair.For our purposes all youneed to do is work out thevoltage required at thebase of the first transistor.

By taking the standardallowance of 0.7V per tran-sistor, you can see that atleast 1.4V is needed on thebase of the first transistorfor the circuit to start towork. As there is only0.81V available, this is thereason for the circuit failingto work.

Rallies AdviceTony Tuite has writtenthis month following onfrom the recentRallies Advice.He mourns thepassing of thedays when youcould buy a reallygood receiver for£3 at a rally.

Tony's 54year old AR88Dhas been passedonto his wife,Joy, now as she's

decided to join the hobbyby doing the Novicecourse. Let's hope Joydoes really well and is onthe air soon.

Tony took me to task fornot mentioning theLlandudno two day rallywhen I was telling you allabout the Picketts Lock andLeicester Amateur RadioShows. The Llandudnorally has been running for

seven years now and hasgrown somewhat over theyears.

My apologies to thosewho support this rally, Ididn't mean to ignore it -honest! I'm sure if youkeep you eyes on the RadioDiary feature, you'll see thedate for this year's showappear before long. If mymemory serves me rightit's usually held inSeptember or October.Many thanks to Tony forthe reminder.

Novice BureauI've also had a letter thismonth from MichaelShread GM6TAN. Heoperates the RSGB UK

Novice QSL Bureau andpoints out that you don'tneed to be a member ofthe RSGB to collect cardsfrom the bureau.

Michael is currentlyholding a large number ofunclaimed cards for Novicelicensees, but is sure thatthey would be welcome.He hasn't had to destroyany cards yet, but he's onlygot so much space to storethem.

So, if you're a Novicelicensee and you think youmight have some cardsawaiting collection, send asuitably -sized pre -paidenvelope with your call -sign, name and address onthe front. You should alsostate how many cards youwant put in the envelopebefore it is posted to you.Don't forget to put the rightvalue in stamps on the

envelope for the number ofcards or you'll have to paythe excess when they'redelivered!

Of course, if you are amember of the RSGB thenyou can send your cardsvia the bureau. Using thebureau can save a greatdeal of money if you spenda lot of your time operatingand QSLing those stationsyou make contact with.

Your envelope shouldgo to: Michael ShreadGM6TAN, 2a Seatown,Gardenstown, Banff,Banffshire AB45 3YQ.

Don't forget, if youreceive a really good QSLcard, send it in and we'llshow everyone else howwell you've done. All cards

are carefully looked afterand returned in one piece.

Another letter I'vereceived this month aboutQSL cards is fromMargaret Christmas. Shehas recently had a batch ofQSL cards printed fromAdur Press.

Margaret found AdurPress advertising in a CBmagazine and has beenvery pleased with the help-ful and swift way her orderwas handled.

To see the kind of workAdur Press can do, send ans.a.e. to: Adur VillagePress, 'Alamosa', ThePaddocks, UpperBeeding, Steyning, WestSussex BN44 3JW. Andbefore you think there's aconnection betweenMargaret and Adur, don'tworry, she just thoughtshe'd pass on the informa-

tion regarding a value formoney QSL service.

Reference BookStill in my QSL theme, I'vegot a reference book in mycollection that I thoughtothers might find useful. Ithink K3CHP's DX QSLGuide is a very unusualbook, especially if you'vejust finished a 'rubberstamp' QSO with say aDanish amateur.

How can you make yourQSL card stand out? Howabout writing your reportin Danish. This is all verywell assuming you aremulti-lingual (and I'm not -just a bit of 0 level Frenchmore years ago than I careto remember!). This iswhere the QSL guidecomes into play.

The guide contains 12standard phrases, such as'Thank you very much forthe Q50', 'my age isyears', 'I hope to meet youagain soon', 'I would bevery grateful for your QSLcard', etc., in 54 differentlanguages! These rangefrom Africaans, throughCambodial, Hindi,Malagache and Sinhala toZulu.

The K3CHP's DX QSLGuide costs $12 postpaidsurface mail to the UK. Ifyou're interested, send to:Joseph MikuckisK3CHP, 6913 FurmanParkway, Riverdale, MD20737-3016, USA.

Now, if you can tell mein which language TerimaKaseh untok QSO says,Thank you for your QSL,you'll go into the biscuit tinfor the prize draw thismonth. The first two out ofthe biscuit tin will win anamateur radio world clockkindly donated by EasternCommunications,Cavendish House,Happisburgh, Norfolk.

Space has caught upwith me again, so cheeriofor now and I'll give youthe answer to the languagequestion next month.
