NewsGodalming Ruled the Air

WavesTitanic Weekend

Godalming, Siiirey. ruled the world‘s airwaves on Saturday 13th and Sunday l4thApril when 2685 radio amateurs in over100 countries used Morse to workGB9QMGY set up to honour thememoryoflocalhe1‘o,JackPhillips.ChiefWirelessTelegraphist on the Titanic which sankon her maiden voyage 90 years ago withthe loss of 1500 lives. MGY was theTitanic's callsign.

The liner stayed afloat for 2 hoursand 40 minutes after striking an iceberg.Jack stayed at his post sendingout distressmessages until losing his life when theship went down. Answering his calls theCarpathia saved over 700 lives.

The special radio station wasoperated by 20 local members of theTitanicWireless Commemorative Groupwho were on the air from 10.30 am onSaturday until 5.47 GMT on Monday15th April precisely 90 years after the lastsignal was received.

“We believed that to exchangegreetings with radio stations worldwide.using Morse like Jack would be a fittingtribute to his heroism. but the resultsexceeded our hopes by far". said Brian

Grist. Chairman ofthe Group.The radio link-up was launched

on the evening of Friday 12th April byBroadcasting Consultant. Ralph Barrett.who gave a talk on the early use of radio

: to summon help and played tapedinterviews with Titanic survivors.

The radio station was run in co-operation with Godalming Museumwhere an exhibition on the life and timesofJack Phillips continues until Saturday25th May. Included is a display ofhistoricMarconi equipment.For further information please contactthe Titanic Wireless Commemorative

Code Cube Announced

Palm Radio Gemtany have produced the'Code Cube', a full-featured electronicmemory keyer that plugs into any Palm ,

Mini Paddle with no external wiringneeded. It measures a mere 25 x 25 x 34mm and for those who prefer a differentpaddle, therewill be a stand—aloneversionofthe 'CodeCube' with a black aluminumhousing. The 'Code Cube' utilizes thepopular Jackson Harbor Press PK3 chip.It is powered by the readily available,long lasting (200 mAh) CR2032 3VLithium Cell which is included.

The 'Code Cube' keying speed is‘

adjustable from 5 to 39 wpm via a handythumbwheel. The preferred speed rangecan be selected with a trim pot on thebottom of the PCB. There is also anintegrated sidetone oscillator whichdrives a built-in piezo buzzer for codepracticing and programming, as well asside-tone if your receiver doesn’t have it.The tone frequency can be adjusted from

500 Hz to about 7KHz, covering theresonant frequency of the piezo buzzer ofabout4 KHz. SMDparts are usedto realizethis miniature keyer.

The ‘Code Cube' has two 50—pluscharacter memories making it usable formost contest exchanges. It also featuresstorage of the station callsign andautomatic CQ. The unit will be availablein black or grey color options for theplastic parts: buttons, wheel, and housingto match either your paddles or rig.

John George (Jack) Phillipsl

by John Young(Godalming Museum)

or the 90th anniversary of the lossof the Titanic. in April 2002.Godalming Town council are

refurbishing the grave of Jack Phillipsand the Phillips family containing Jack‘sfather. George, mother, Ann and twinsisters Elsie and Ethel. in the OldCemetery.NightingaleRoad. In the centreof a six foot square curb, all in whitemarble. is an obelisk in the shape of aniceberg. a fitting memorial to theGodalming hero.

Jack Phillips was born inGodalming. Surrey. at 11 FarncombeStreet.on 11 April 1887. As ayoung boy.Jack sang in the Choir at the ParishChurchof St John the Evangelist, where there isa brassmemorial plaque.He was educatedat the Godalming Grammar School. Onleaving he worked at the local Post Officeas a telegraphist. where he learned hisMorse code.

In 1906 Jack joined the Marconitraining school at Liverpool and. oncompletion ofthe course. headed the listof successfulcandidates in the PostmasterGeneral examinations.

Jack was considered a seriousyoung man who stood high in theconfidenceof his supeliors in the MarconiMarineCompany. He progressed steadilyto the top of his chosen profession andserved on the ocean-going liners8

Teutonic. Lusitania. Mauritania.Campania. Oceanic. Corsican. Canada.Victoria. Danube. Pretorian and Adriatic.He spent three years at Clifden. theMarconi high powered transmittingstation on the West coast of Ireland.

Jackwas appointedChiefWirelessTelegraphist on the new, “unsinkable”luxury liner RMS Titanic. with HaroldBride as hisjunior operator. The wirelessequipment on board was the mostmodernand most powerful of any merchant shipthen afloat. It had a range of 250 - 400miles in daytime and at night. whenconditions for transmitting and receivingwere more favourable. it occasionallyspanned 2.000 miles. It is recorded thatJack had confided in a friend that whilehe was proud to be chosen to serve 011 theTitanic he would have prefen‘eda smallervessel. Jack also expressed a dread oficebergs.

In the 24 hours preceding thefateful collision with an iceberg on 14April. 1912. the two wireless operatorshad been busy repairing a fault in thetransmitter. As a consequence. Jack hadvery little sleep before commencing hiswatch from 8.00pm to 2.00am. It was inthe hours preceding the collision that theliner achieved its highest speed of 22.5knots. Thus. on impact. the iceberginflicted considerable damage to many

of the ‘wateltight' compartments,causingit to sink at the bow.

Jack was still sending personalmessages from the passengersto America.This was his job with Marconi when hewas first instructed by the captain toadvise other vessels in the area of thecollision with the berg. Due to the muchpublicised and widely believed claimthat the Titanic was an unsinkable shipalmost all on board carried on as beforeand other ships receiving this messagedid not immediately prepare to head forthe given position of the stricken liner.

However, it was soon realized thatthe Titanic was sinking and Jack wasinstructed by Captain Edward Smith tosend out the SOS messages requestingimmediate assistance from all vessels inthe area.

From this time onwards Jackstayed at his post, sending out the distressMateo — ‘flpn'l2002

calls, advising on the latest position ofthe Titanic, urging and convincing otherships to assist in the rescue of those takingto the boats. Jack even stayed at thetransmitter while Harold Bride put alifejacket on him after the Captain gavethe instruction: "Every man for himself"and had personally thanked the twowireless operators for their perseverance.

Bride was sent off by Phillips tosave himself, while Jack continuedtransmitting. It was as a consequence ofthis total devotion to duty that JackPhillips lost his life and has since becomewidely admired. It was this bravery andpersistence which reduced the magnitudeof the disaster in respect of lives lost.Jack’s last message was picked up at 2. l 7am and the ship foundered at 2.20 am.

The Phillips Memorial inGodalming, a garden designed byGertrude Jekyll, with a magnificentbrick Cloister 80 feet square designed byHugh Thackeray Turner, was laid out,built and opened exactly two years to theday after the sinking. The memorial issituated between the River Way andGodalming Parish Church. Within theCloister, the Wireless and TelegraphCompany commissioned and haderecteda memorial stone tablet to the perpetualhonour of this brave young man, whodied four days after his 25th birthday,leaving behind a lasting example ofputting the lives of others before one‘sown.

The Romansset up a lighthouse on the cliffs. theNormans a substantial castle but therewas no navy and defence of the realm atsea was by an obligation laid on Dover.Sandwich. Hythe.

The word 'telegraph' means'writingat a distance‘ and the firsteffectivedevices were optical not electrical. Thebest known, Chappe's. used a pole andmoveable arms to send 192 differentsignals: observations by telescopes alonga chain of stations allowed for messagesto be relayed fromParis to Lille.

It was the first significantsubmarine cable but failed after a fewhours. According to one account afisherman had trawled up apiece. This heexhibited in Boulogne and thought it tobe a new kind of brown kelp with gold inits centre. It is believed that this 'pescatoreignobile' returned again and again tosearch for further specimens (Russell1865). Many believed that the failurefully justified their views that the projectwas a mad hoax or gigantic swindle,indulged in only by wild minds.

A more robust cable. weighing180 tons, was laid nearby in the autumnof 1851 to run between South Forelandnear Dover and Sangatte close to Calais.It had four wires instead of merely oneand each, of No. 18 Birmingham WireGauge (0.65 in. diameter). was separatelycoated with gutta percha (Figure 8). Asimilar coating covered the four and itwas also bound by yarn dipped in meltedtar and tallow. As protection the cablehad a tight spiral sheathing of tengalvanized iron wires each of No. 1

OnwardConnectionsConnections through continental

Europe had reached Turkey in time for acable 340miles long under the Black Seato allow signals from London to be sentto British forces fighting in the Crimeanwar (1853—1856). For many years theconnections to France through Doverplayed a major role in world history. Inthe Edwardian period some of the trafficfrom Dover to the continent is likely tohave been handled by my uncle, Jim W.Simmons, then a telegraphist in the postoffice.

Long distance working had manyproblems as Preece & Sivewright ( 1876)made clear:-

‘Different portions of the earth...are frequently at different potentials.When these ...are connected together bywire we have earth currents. The currents

MM80 - J7lpri[2002

vary in strength and duration duringdifferent periods of the day and year, andat certain seasons they acquire suchmagnitudeas to be called "electricstorms”They then intemtpt the circuits to such anextent as to render working difficult andeven impracticable. On long cables theyare specially prevalent, and become ofsuch strength as to endanger the safety ofthe cable. They are to be guarded againstin two ways lst, by dispensing with theearth andusing a secondwire as the returnwire, working, as it is called, in a metalliccircuit. 2nd, by using condensers andworking with a broken or interruptedcircuit. . .The first method is used chieflyon land lines because it can be easily andrapidly resorted to, and on cables whenthere are wires available; but the secondmethod is that which is principally usedon cables, and it is very effective.’

Telegraphs in IndiaA licentiate of the Royal College

of Surgeons of Edinburgh in 1829,

William Brooke O'Shaughnessy, willhave studied anatomy with cadaversprovided by the notorious Burke andHare murderersand will havebeen a fellowstudentwithCharles Darwinwho studiedmedicine forjust a year. O'Shaughnessy,introduced cannabis to the West, madeimportantstudiesof the use of intravenousinfusions to replace the water lost incholera and went to India as an assistantsurgeon. Being especially interested inelectrical matters, he was spotted by,arguablythe best, Govemor—General ever,a Scottish noble, Lord Dalhousie, whogave priority to communications.

O'Shaughnessy set up in theBotanical Gardens of Calcutta anexperimental line of No 14 BWG ironwire running backwards and forwards forcompactnesson 42 rowsofbamboopoles;the lengthwas30miles ! His firstidea wasto use induction shocks to be perceivedby the operator at the far end! He laid acable under the Hoogly river and blew upa wreckedshipusing an undem‘atercable.

Dalhousie. considering the observationspromising. sentO'Shaughnessy to Britainwith a letter to the Directors of the EastIndia Company requesting support forintroducing telegraphs. O'Shaughnessy.appointed Director of Telegraphs forIndia, became in charge of an office at thePresidency and through his efforts themajorcities were linked by 4.000miles ofcable. The lines. erected by unskilledlabour, had to pass through jungle andspan wide rivers without bridges.Lighteningstn'kes killedbirdson the wiresand sometimes destroyed telegraphicinstruments: wildbuffalos nibbed againstand at times knocked down telegraphposts. 322 miles of the Madras line weresupported on granite obelisks. Someequipment O‘Shaughnessy himself devisedusing local materials; Morse equipment. notused initially. was orderedin 1856

A suitable battery for India was

the 'Minotto'. A glazed jar with a copperplate at the bottom as one electrode wasfilled with copper sulphate. liver waterand sand was caped with a zinc electrode(Figure 9). The copper sulphate wasreadily available in local bazaars becauseit was believed to have medicinalproperties. It was 1879 before a generatorwas used: L. Schwendler passed cuirentfrom a lighting generator in Aliporethrough 850 miles of telegraphic linebetween Agra and Calcutta. Telegramswere successfully sent and no changewasnoticed in the brightness of the electriclight. for the proportion of the cun'entconducted away was only about .0043 ofthe total current.‘ (Higgs 1884).

London to IndiaOn 24th March 1854 the first

telegraphic message between Agra andCalcutta. 800miles. was passed. A cable

By1856 all major parts ofIndia were linked.Signals to India fromBritain may all havepassed through Doverand played a majorrole in the militarymanagement of theIndian Mutiny in1857.

FEWDEDICATEDconstructorsstill delight in building their owngear. I wishmore would do so. as

the act of communicating usingsomething that contains something ofyou is deep and satisfying. Ron.ZL l AJP.is one of these. He recently built anElecraft Kl kit. A lot of people havepraised this rig. so I induced him to writea review. Here's what he says:

The K1 was released not longbefore last Christmas, and I have number575. which gives some indication of itspopularity! A smaller version of the K2.it is a two band. 7 wattmaximum. microprocessor controlledQRP. CW—only rig with an LCDdisplay.

The kitset airives in a small box.This appears to contain mostly a nicebound manual. and lots of bubblepacking! But this hides several bags. eachlabeled to indicate the section they relateto. and the hardware (case sides. and PCboards) wrapped in brown paper.

Assembling as detailed in the veryprecise instruction book, the set rapidlystarts looking like a radio. The resistorsare doneup in ”bandoliers"foreach stage.all arranged in the order laid out in theassembly instructions. A very nice touch!The first module constructed is the"Filter Board”. containingallthe pre-mix.Band pass low pass filters. It also has thePIC controller and a couple of crystals.

Once that section is completed.the front panel is made up, and anothernice touch is a simple spacer supplied to

enable all the push buttons to be mountedat the same level above the pc board. Afewmore components are added. then thelarge display driver chip. followed bythe LED display. The completed unit isput to one side. The RF board is alsopretty straightforward, and after a coupleof pages of components, the set is readyto be fired up. It took me 16 hours to puttogether. One massive 12 hour stint(couldn't put it down) and 4 hours tofinish off the next morning (early!)

At this point I found the onlyinstruction I wasn‘t entirely happy with!This states ”turn on S l. Ifyou see orsmellsmoke. or a component feels hot to thetouch.disconnectthe power source". NowI find that a wee bit basic. Surely someindication of what sort of currentyou might expect would be nicer? Fromthere, construction consists of addingsections. plugging the boards togetherand using the LCD display to verify thateach section is working correctly.

Alignmentwas easy. I used a weaksignal source to align the filters, whichtune very sharply. The same coils are

MM80 -aprirzooz

used for transmit and receive. It was timeto check it out on air. It didn't take longto work out all the menu functions and setit up to suit me.

Kl FeaturesThe completed kit is shown in figure 1.The receiver covers either 80 or 150 kHz(preset during construction), tuned via a10 turn pot. There's a 4 pole crystal filterwith3 selectablefilter widths,a selectableattenuator, "S" meter, RIT, and XIT.Sensitivity is quoted as being 0.15uv for10 db (S+N)/N. Band-changing is madeby "double tapping" a button. Bandfrequencies are selected when you order.There is a choice ofany two from a selectionof six available bands. The built-in keyerruns from 8 to 50 wpm, with selectableiambicmodesA or B, and adjustableQSKtiming.

A menu allows 16 other functionsto be adjusted/changed. These include

W80 —flprzf2002

sidetone pitch and volume level, poweroutput (from0.1 to 7 watts), bandwidth ofeach of the three Xtal filter settings, andoptionally turningLED'son/off forpowersaving.

Another smaller menu selects "5"meter on/off, provides a battery voltagereading, and provides a 6 digit frequencyreadout froma 3 digitLCDdisplay!Whenthe button is depressed quickly, thereadout might show, for example 14, then014, then 14.9, meaning a frequency of14.0149 MHZ. Normally, the readoutwould just show "14.9" the last threedigits. It may sound strange, but is easy toget used to.

Being a simpler rig than the K2,the K1 uses a VFO which is varactortuned, but which is very well designed,with very little drift. Elecraft claim <ZOOHZ per hour after 5 minutes at 25°C. For a set measuring only 2.2" x 5.2" x5.6" there are a mighty lot of features! To

19

complement the basic kit. a built inautomatic ATU and noise blanker arealso available.

OperationTheK1 draws700 - 800 mA at 14V

011 transmit. typically 50 mA on receive.I power it from a 12 amp/hr Gel cell.floating on a charger. However. it wouldprobably last me for a week's operatingon the battery alone. The receiver is verylively. and stations tune easily. A callor two soon produced results. and aUTZDX was the first call in the set's logbook.

My first coupleofweeksoperationincluding a stint at the beach as a /Pstation. I used an 80m dipole with myYaesu FC-QOI tuner to tune up on 20111.

The book says "Load tolerance: An SWRof211 orbetter is recommended.However.it will survive high SWR operation."

The K1 was an absolute gem touse! It was hard to find fault. but I did findthat the "thump" made by the AGCcapacitorinitially charging up on a strongsignal was a bit annoying. However. asimple mod was posted which slows thecharge-up time. and this eliminatesthe thump. I have also now installed theKNB I noise blanker. This is quite a trickypiece of circuitry with 3 stages ofamplification. AGC. bandpass filter.noise gate. and thresholdcontrol. controlled by a PIC chip. Thereare two settings. HI and L0. The manualsays. "With HI selected,only strongnoisepulses will activate the blanker. howeverin manycasesthe LO settingwill be moreeffective" (whatever that means).

To check this out. I took it up tothe WhangareiClubrooms to try it against

20

the resident electric fence. It was great! Itcompletely removed the fence pulses onthe HI setting.

The kit is available direct fromElectraft. Their service is first class. butthe way our dollar rates against the USdollarmakes the price, $US 260 + postagea bit depressing. Start saving those “greenstamps" from your QSLs! For orderingdetails. see the web sitewww.Elecraft.com"

I've nowworkedRon several timeswith his Kl. It sounds fine. and he hasbeen pulling in the DX. Everybody whohas this kit seems to like it. And with agoodantenna and a ZLcallsign. the worldwants to talk to you. regardless of yourpower! See later.

Portable at EasterI took the T5505 up north to my

sister's farm for a few days. I operateportable from the tailgate of the wagon.in the open air. powered by a gel-cell. Ifthere are trees around I often use my end—

fedrandom wire. But this time I wanted toexperiment with a new configurationfor my Trident mobile whip. I've nevermounted this permanently. I simplyclamped the base—plate on which it'sbolted to the roof-rackofmy Commodorestation wagon. This always worked fine.and gave a rapidly—deployable. non-invasive setup which grounded theantenna firmly to the vehicle roof. Butnow the Commodore has left me for theplace to which all faithfulold Commodores go. and I have a muchnewer Toyota Camry wagon.

But the Camry has no roof—rack.Rather than having one fitted. I decidedto try non-ohmic. capacitive coupling

M91180 — :aprif2002

between the baseplate and roof. Thealuminium whip baseplate is 48 cm by 8cm. and I'd fashioned a wooden frame,padded with foam, to position it with amean spacing of about 2 cm above theroof. This gives a plate—to—roofcapacitance of only about 17 pF.For added sanitization I connected thebaseplate to the tow—bar with a batteryjumper cable.

On the Commodore, the whip hadalways loaded OK connected directly tothe rig on 40. 20 and 15 metres, with anSWR of 1.5 or less in the CW bands. ButI usually inserted my MFJ 945Dtransmatchanyway.to get an exactmatch,and enable operation in the SSB portionsas well.

Not surprisingly, the SWR on thecoax to the whip was much higher now.Nevertheless, the transmatch stillbrought it down to 1:1 on 20 metres.although I had to use a larger thannormal inductance, with the inputcapacitor nearly at minimum. (Thismeans that the transmatch characteristicimpedance was high. implying a veryreactive feed point impedance. I'llexplain that in a forthcoming article onunbalanced transmatches).

My sister's house is on a high.treeless hill. an excellent DX location.away from the Auckland RF noise. Atsunset. my first 50 watt CQ generated apile—up from all over Europe, whichgrew steadily more cacophonous. I

worked non—stop for an hour, getting andgiving reports of 559 to 599. The pile-upwas still growing when my gel-cell ranlow. I promised to return in 24 hours.

Next night, the pile—up was evenlarger thanbefore. In fact. several stationsM91480 — flpnf2002

who had missed out the first night werewaitingforme, and thankedme forcomingback. Again, I worked DX non-stop untilthe gel-cell ran down.

For interest. I asked everybodywhat power and antenna theywere using.The answers ranged from "25 watts intoan inverted vee", to "700 watts into a 4element monobander". Most were using100 watts into dipoles or simple beams.The signalreports I gavedidn't vary much.It's propagation conditions that are thecontrolling factor in my experience, andI was only picking off the strong ones.

So using tenuous capacitivecoupling between the whip and the roofobviously worked, although a largerbaseplate.moulded to the roof-shapewithonly a thin paint-protecting foam layerwould be better still. Has anyone elsedone anything like this? Tell us about it.Two observations ocun‘ed to me. Firstly,when 20 metres is open. from anyreasonable locationZLs canworkendlessCW DX. with only battery power and amobile whip. And (as I have observedmany times before) you only have to callCQ once to generate a pileup.

Secondly, the interest myappearance raises every time I do thisindicates howrarewe are perceived to be.Everybodywants to talk to us! In fact, I'vejust received a couple of lettersfrom recently qualified ops who havemarginal antennas and/or locations. Theyhad little success with DX SSB. so withsome trepidation. tried CW. Both wereastonished at the difference. One said,"They told me that CWwas dying. but thereare hundredsof stations out there! I had towork abit to get my speed up to 15 - 18 wpm,but then. it was so easy!" MM

A set of 15 discsexists that is labeled A through 0 with nonumber designation (Figure 6b).

It is not known with certainty butit is suspected that the discs for single-disc instruments were numberedwhereasthe discs for instruments employingmultiple stacked discs bore thealphanumeric designations.

Alphanumeric discs are knownup the ‘9‘ series however it is unknown ifmore than 9 sets ofdiscs exist. The lowestnumbered series of discs (series 1 and 2for example) had simple code groupswhereas the highest numbered series (8and 9) had more complex messagesincluding numbers and punctuationcharacters.

Nine sets of 15 discs may exist forboth Morse and continental code for atotal of 135 discs for each code. Thehighest numbered disc encountered bythe author is ‘19‘, suggesting that at least19 numbered discs exist.

Morse discs were identical inappearance to Continental code discsand the company made no attempt todifferentiate one from the other based onappearance. The only way to tell Morsefrom Continental discs is to visuallyinspect the discs. looking for the{Ma/[80 _ aprimooz

characteristic Morse Characters that weredistinct form the continental codecharacters.

In addition to the discs that wereincluded with the initial purchase of theinstmment. additional discs could beobtained at modest cost. T h ecompany also permitted students toexchange theirdiscs for different ones fora 2 cent per disc postage and handlingfee. Ifone ordered5 extradiscs fora 5 discinstrument. it is suspected that the studentwould receive the first, second. or thirdset of 5 discs of a 15 disc sequence.

Transcription of the discs hasdemonstrated that sometimes thecompany mislabeled the discs. A 7-Ldisc owned by a collector is the same asa 7-1 disc in the author's collection. Othercollectors have other discs with the samemessages on discs with differentalphanumeric designations suggestingincon‘ect labeling. The authorhas severalalphanumeric discswith the lettercrossedout and another letter stamped next to itas a c011‘ection. Anotherdisc has the letterdesignation on the disc upside down.The findingofinconsistent and elroneouslabeling of discs suggests that disclabeling was not automated. and thathuman errors were not rare in labelingdiscs.

The author's experience and theanecdotal experience of other collectorsis that most discs encountered are thethicker discs used in the multidiscinstruments.The 6 thin discs in the author‘ spossession are all American Morse.

The Titanic Wireless System

by W. R Jones

he article, Signals fromthe Titanicby Dr Gary Bold in MM78 set meoff delving into my notes about

the methods that were available then todetect the spark transmissions. The threetypes that Marconi—equipped ships hadfitted at the time of the Titanic were themagnetic detector, the valve diodereceiver or the crystal receiver. Themagneticdetectorhad held sway for manyyears before the valve detector wasdeveloped.

There were two devices whichhandled the signal that emerged from themutual inductor; the first was thetelephone condenser.This condenser wasdivided into three groups of 0.55, 0.11and 0.22 microfarads. Three brass plugsenabled 7 different combinations ofcondenser to be obtained. By variationsthis was used to sharpen the tone of thesignals in the headphone to improvereception.

The second instrument was themultiple tuner which contains variableinductances and condensers forthe aerialreceiving circuit. It had 4 ranges. whichcovered 80 to 150 metres, 150 to 1600metres, 1600 to 2000 metres and 2000 to2600 metres.

When the ship was not incommunication with another station thesafe watch-keeping channel was40

monitored with the multi tuner in the'stand-by’ position with the aerialcondenser shorted and no inductance incircuit.Duringcommunications the multituner was brought in to play to tune theaerial for maximum signal strength.

As regards the asymmetricmountings of the magnets in Dr. Bold‘sfigure 2 schematic, there were only twopositions for the magnets with respect tothe mutual inductorcoils. The first wouldbe with poles S-N / N-S (normal position)with this position it will be seen that likepoles are together this produced a hissingsound in the headphones when the bandwas moving.

In the second position the magnethas less influence on the mutual inductorand the hiss is eliminated. This breathingaffect interfered with and made weaksignals difficult to read - it was a matterofoperator choice. The re—arrangementwould entail removal of the bracket,which holds the magnets. The secondarrangement would reduce the receiver‘5sensitivity. With the Hissing present itwas indicative that the band was stillmoving. The clockwork when fullywound would drive the band forapproximately 100 minutes and it ransilently.

The standard 1.5 kW wirelesstransmitter. used on many ships at the

Info Please MM79 AWA Key

Last year in September. I asked an oldfriend in Melbourne, Doug Twigg if heknew the history of the AWAManipulating key. I owned one yearsago. with a slightly different operatingknob to that on page 32 of MM79. Dougcameback and this is a précis ofhis reply:

Yes, I know this key very well; it has beenaround in a lot of radio stations inAustralia as long as [have been in radiocomnumicatt’ons. at least since WWII.ntaybe earlier/l

[first saw them in use at the RAN(Royal Australian Navy) shore stations,atHar/nan(Canberra) etal. Then in DCA(Dept ofCivilAviation) aeradio stations,especially theolderoneslikeMelbourne,Mildura, Launceston and Hobart.

As you know AWA used to operateall coastal and aeradio stations inAustralia before WWII. before the OTC(Overseas TelecommunicationsConunission)andtheDCA took overtheiroperations, but the older stations werebuilt by AWA and the radio equipmentinstallationswerentanufacturedbyAWA,including the Morse keys - everything/f

AWA also installed the radioequipment in most oft/1e slzipsflying the

44

Australian flag, also Australianregistered aircraft. They also providedthe radio staff to operate and maintainthem.

Well so muchfor the history. butthere were a lot ofAWA manipulatingkeys around, particularlythe type in thepicture you sent to me. Later Clipsalstartedmanufacturing Morse keys alongwith other electrical hardware. Thesebecame common in the 50's and 60 's, asAWA withdrewfi'onz this type ofmarket.

Doug was Principal RadioTechnical Officer for the AustralianAntarcticDivisionformanyyears. servedas a radio officer. and an officer in chargeof Antarctic stations as well. As ayoungster. he was trained by the RAN asa radio telegraphist. He can read bothradio CW and sounder Morse.

Allan tVIoore VKIALBerlin, Germany

Just a few comments on the AWAkey onpage 32 of MM79. The key on page 46 inMM57 and this one are not identical.There are at least two versions ofthis keywith minor differences.

The MM57 key has a halfcentimetre higher lower contact support(fixed to the base) and therefore a

Mfllé’ti - lepril2002

correspondingly higher fulcrum than theMM79 key. The labels differ from eachother and the MM79 key has distinctivegrooved washers under the two outerterminal screws.

The knobs seem to varyconsiderably - maybe from laterreplacements by owners or perhapswhateverwas availableduringWWII. wasused. However I believe the knob showninMM79is the correctone for this version.The other version seems to have mainlycarried a 'WT 8 AMP‘ type of knob withno skirt. I have seen others with a largerflatter type with a skirt beneath. Maybeone versionwasmade for civilian use andthe other military.

I think the vintage would be late1930s to early 1940s and were made forthe military for use in radio sets. AWA(Amalgamated Wireless Australasia)made a varietyofelectrical items — radios,TVs, refrigerators etc amongst otherthings.

I have recently contacted the firmand was told the company is no longer amanufacturer and in an entirely differentbusiness. They had no records pertainingto Morse keys. This may be of someinterest to readers.

The 'Musonic‘ BuzzerBox is verysimilar to the buzzer on my GamagesKey. 1 have searched the internet andMargo — apnf2002

‘Musonic' are still trading, ifin fact theyare one and the same company(www.Musonic.c0.uk) They sell Hi-Fiparts, record sleeves, stylus bits andpieces.

History of the AustralianTelegraph

I‘ ve embarkedon the taskofwriting aboutthe beginnings of the telegraph inAustralia and I wonderif any readers haveknowledge of the beginnings of theelectric telegraph in Victoria.

MuchhasbeenwrittenaboutToddbut almost nothing about SamuelMcGowan the pioneer whobegan it all in1853/4 in Melbourne, Victoria. I havelearned a lot about the actual spread ofthe system in Victoria, the promotion ofthe idea by the Argus newspaper,McGowan‘s reports to parliament and alittle from a centenary publication ofKorowaCEGirl‘sSchool. Howeverl‘veyet to find any significant primarysources, e.g. letters, diary etc..

I believe that some of the familymay be still live in Ontario fromwhere hecame and members of the family of hiswifeAnnieBensonmay still live here andin Canada. No one has written anysignificant piece on the man himself.

Army Signallers

I came across an old photo of what I thinkare BritishArmysignallers. Howeveronthe reverse of the card are the words“CARTE POSTAL” which suggests aFrench connection — prhaps WWI.

If you look carefully the Morsekeys can just be seen on top of the smallsignalling lamps. The men look veryproficient with their semaphore flags.These were the days when flags, lampsand wire telegraphs were the mainmeansof military communication.

I would be very interested to hearform anyone who can provide furtherinformation; date, regiment, place etc.
