\Yhenever several broadrosc li~tt:-ncra 01· l'X­

pel'imenters get, together, their conversation drift,; aimlegs!y from one topic l<1 ,inother, until fiually some 011,• bring~ up t.he sub,iect of reg1,11cration, One man will state pu~itiveJy lh:it regenerntion in the present state c,f rndio broadcast develop­ment is an abominable evil, that it i~ responsible for distorted reception b~· ils user, and owing lo hs radiating properties ~poils O.X. reception for hunili·e,ls of other listeners.in. A11other whn hos probably ne,,er u~•<l any other circuit than the P one circuit, emphaliClllly declare~ lhti t. 1·egenr,r:,l1011 is the mo~t valmiule phenomenon oi :di rndio 1·e­ceptfon, ru1d lhat its use should lie fr~rdy <'ncour­aged. U one analy~e~ lhc ~ituation from a eool and unbiased sland poin~, he will be forced to voice tl1e conclusion that ihe contenliun, of both men are very worthy of support, nl though neither debater is fully justified in demanding a completP capitulation to hi, iueM.

A rgnments for Regeneration. Suppo1'lers of regt·norntion base their argu­

n1ent,s :ilong the follovting Imes. They show rather convincingly that regeneration has been the outstanding feature in some fom1 or other of prac­tically cve1·y receiver prntlurc•d since A.rm$lrong discovered it some t'\vel~e years ago. They tak<: particular ,folight in pointing out th~ cconom}' p,;r tube oi Lhe ,·egoncrotive set, and will quote in­stance afte1· in~tnnce in which simple home con­stn1ction set!< of one, two, or three valves lmve outranked in performance formiduble commercially made outfits usiug twice the numb,•r o! vah·es. They declare that simplicity, economy an<l unfail• ing effective11t•ss of circuits similar to th() P one have done more t-0 popularise radio broudcastmg than any other factor. Against R~gcncralion.

The opponents of regeneration cheeriully :.nd disarmingly admit the truth of these assertion~. They probably then commence Lhe defence of their own position by accusing their I-rfonds of failing to observe a proper perspective of the radio broad­cast situation as it exists to.day. They state, whereas the radio experimenter has little more I.ban code to listen to, the average m()dern set owner is wholly intct"ested in speech or music. They pr«eed by demonstrating that the entire tbeoeretical and practkal function of 1·cgcnerntion

is ab~olutely and une,1uivocall~• op!Josed to t.he be•I intt:rest~ ()f radio telephony, and that while 1'€gen~i·alion in all t:tses !l.Bsi.sts the code signal, 1t invariably l~nda to distort and destroy the char­acteristics of the telephonic one. They win<l up with a grand f!ou,.ish to l.hc effect that the radiat­ing properties alone tonstitute sufficient reason for the banishm~nl of te,::eneration from all brond­ta.st l'CCf'iV('Tl-,.

or two itemB, and note the difference in tone and quality.

The feedbacl< action, I.he supplying of addition­al energy to the weak signals -picked up by the aerial, builds up the irregular impulses that make up radio telephon" speech or music and l'han.ge~ their characlerislic shape. Tho signu.ls .nre in­crca~cd in volume, yes, but at the same time th"Y are robbed of their lone qualit.ies, and are repro­duced as distorted sounds. Exponents of l'ej!"enera­tion will probably answer I.his objection by saying that the extent of the damage to the quality of tone depends on the limit-~ to which the r~edback is pushed. They suggest that I.he set owner renuce the coupling or use a ~muller tic lclc1· coit Their <•JIPOnents usually have the lai<L word in lhe tllili­ter by srsting that if lbe co1.1-pli11g or tickler is 1·e1luced lh~ i>pernLQr will lo.e ,nuplificatiou so rapidly that he probably will not be satisfied with the volume of rcspon~~. Conclusions.

Thia phase of' tho que•tion i• obviously debllt­able for ever, but without a doubt it is exactly what is happening in the cities and the suburbs every night. so rnany listeners-in are endeavour­ing to receive the Jntcr-Stat(' slutions ns satis­foctQry volume (with impossible sets), thnt the results all round are far from satisfactot·y. The probkm of radiation caused by regenerative ~els bas been dealt with mnny tin1cs in "Wireless Week­ly," and it is not nccc~,;ary to repeat here the many descriptions of the weird squeal, and whistles every radio set owner has heard. Those howi•vcr, who admire regeneration and wh-, are n()t conte11t t-, sit back and see a valuable radio asset outlawed should exp01'iment with circuits similar to the Browning Drake circuit, or the neutrodyne with the platt, circuit of the detector valve tuned. Jn both these circuits, moans iu·e provided for the ncu• t,ralisation of the internal capacity effect of the II.F. amplifier valve or valves. In the case of the Browning Drake cfrcuit the tiekler coil in the plate circuit or the detector \1al ve is arrnngcrl in the or• dinary electrical and mech11nical rnanner, but it is mudc pu,·posely small to keep the entire set stable and free of oscillation.

This method of regeneration furnishc~ enough protcc.tion from 1-adialion and ~ufficient incroasr in ~eleetivity and $C.nF.itive.ncs~ lo make it well wort~, while experimenting wikh. Both the Browning Drake and Neutrodyne receiver (with regenerative detector valve) hn,•c recently been de;;cribed in "Wireless Wet~kty;· $0 that turthor spnco will nut be taken up now, claiming their wonderful adva11 tag<,s over the ordinary regencmtive type of re­ceiver. There is no doubt however, that these types of receivers afford a favourable balance bet-

ween the Uillldorned straight Togencrotive hook ups and the multi stage R.F. outflls that should content both the exponents and opponents of regeneration. The exponent!! should be satisfied because they will be able to see the tickler coils flapping against the secondary, t.he opponents can concede that radia­tion and distortion will exist in quantities too small to make themselves manifest.

(Editors Note: We again suggest to city readers who are at present t1sing full regencrulivo sets Lo cxperimenl along the lines described in "Wire.less Weekly's" article of Nov. 20, 1925, "H.F. Amplification with cor.1·ecl ]\"eutralis.ation." Re­membPr that one evening's dial-I.wisting wilb a regenerative receivct· will indirectly cause poorer -programme!< not only from your local st11tion hut l"rom the Inter-State station :clso.)

A sati;;fied user in Sydney tells us that the ,mperb JGRANIC honeycomb coils, for in­~ta11cc, mean all the difference bclwMn his got Ung, and not getting. far dist.ant stations.

:limilarJy with broadca~l reception; iJ you will have the purest reception with the full­est volume you must u~e quality apparalu::;­nml the lGRANIC trade mark on any article symbolises the highest quality.

A 1·e yon disappointed wilh, and - perhaps a little weary of your present Radio activities? Then why not scrap those cheap and nasty parts-and build a better set with IGRANIC Radio Devices.

An Appret"iation ..

"I hav~ pleuuro in ndvising that the> Super Radio Frequency Transformer you recently sup­plied to me has proved an unqualified success.'' says R. R. Higginson, Wyong Road, J\fo~rnnn, in a Jetter to Amalgamated Wireles:s.

" I would unhesitatingly rocommend anyone de­~irous of adding a atage nf radio to use t he "Super" -it does not make the &et any more difficult to handle, but the volume and quality of reception i,. considerably improved, being nli that could be po~­sibly desired.

It ill all the more pleasing to me to obtain such wonderful results with an Aust.ralian article, and 1 anxiously look for-ward to the further de­\'elopment oC A.W.A. products."

ls he tall 1 ls he thin? ls he short? Is he fat 1 Do you love him 7 Do )·ou like his voice 7 Does he make you laugh? Do you look forwar<I to his stories?

Thi• following lillle known calls have heen QSA in Australia of late: NCGl the U.S. Coast Guard Radin Repair :Base, Navy Yarrl, Philadelphia, on the 40 met.re band. NOSN, U.S. Submarine base, Coco Solo, Panama. WlK, Radio Corporation of America, situated in ::slew BrunS\,;ck-QRH. 22 m<,tres.

Aceording to our log of some months ago U5ZAI was one of the loudest sLstions in the world. 'rhe aforementioned log, however, docs not mention vei·y complim1•nlary things about bis QSB. Seeing that pretty well every DX m&rcbant in Auslralia has logged lhis bird, we think some particulars may be of inli,rest. The nrrial nr 6ZAl is of the inverted "L" type, GO feet long and i~ a two foot six wire cnge, On 80 metres ('\\•here we not.ad him) the ante.nnn ape.rat.es on its 1st hal'monic, on 40 metres its 3rd, while on 20 metres the 5th i~ use1l. Counterpoise is a copy of the aerial. Plate ~11pply is obtained from a H k.w. 2000 volt Eseo Motor Generator. UV204A'~ are used in all the t,•aJL~mitters.

Judging from various foroign DX lists which we have given the once over, Lhe .following Aussie stations are well in Lhe limelight, elsewhe~e, and have ~eason to feel happy: 2Cll1, 2Bl:I, 2BK, 2DS, ZJ\V, 210, 2RJ, 2SW, 2YH, 2YI, 2CS, 2YG, 2GW, 2ZN, 2LO, 3BD, 3BQ, HAD, 3AK, 3Al', 3EF, 3KB, 3LM, 3YX, tlJX, mm, !1SL, 4GD, 5AII, 5BG, 5LM, !lAG, 7,IH, 2WS.
