Gas-bing aside levi-fcy^ fur-ther on you'll find a summary of -the Federal President
report, and at our las-t southern general meeting portions of -the Geneva Report were
read. From these two reports the following fact 'becomes clear. The danger of losing
our operating frequencies is a very real one» There 'are'12 9 governments -w ich take
part in -bhe proceedings oZ frequency allocation conferences and each one has an
equal vote. Currently, th.ere are only 64 IAEU socie-bies which means -bhat the IARU
represen-fcs only one-half of the coun-tries who cast a vote in the ITU. Encroachment
by commercials into amateur 'bands is more than serious now, What will i-fc be in a
few years? Every one of us must play his part in keeping 'the bands filled. If
no-thing else give a test call. Only oonsta. nt use of the amateur bands will preserve
them in the all-'fcoo-near future.

EXTRACTS FROM FEDERAL PRESIDENTS REPORT. APRIL 1965—MARCH 1966.
The following extrac-ts are -taken from -the report presented a-fc the 30th Federal
Convention of -the Wireless Ins-fci-tu-be of Australia, held in Brisbane over Eas-ber.
"..,... One of the largest projects undertaken by the executive of the Federal
Council of -the Wo I. A. in many years has Tseen the almost complete re-write of the
Handbook for Operators of Radio Stations in the Amateur Service. A-t -the -time of wi-te
writing -this report, there remains only the resolution of one or -two problems, and I
am confiden-fc -bhat -these will be resolved -to our s a-tisf action in the near future. It
is true -bo say -that we have not acheived every advantage we would have liked in -this
re-write. There has been the necessity -to give a li-t-tle as well as -bake, Tsu-t -the
net result will Tse a Hand'book devoid, of many of the amlsigui-ties and- unrealis-bio-
res-trictions which have " bugged " -the Amateur Service for years.
So far b ok as I csn remember, -there have been instances of direc-fc action by
Divisions and/or individuals to obtain approvals from -the Depar-tmen-t to engage in
some activity which currently is not covered by the general regulations under
which the Amateur service operates, or -to bring abou-fc some chsnge in existing
conditions due to exigencies of one kind or ano-bher. Such d. irec-b ac-bion bas gener-
ally resul-fced in refusal and- by the time the mat'ter has reached Exeou-fcive level, a
great deal of damage i.. ^,rela;tionships has resulted and your Executive has at -bimes
Taeen placed in an embarassing posi-tiono I WOULD THEREFORE STRESS MOST STRONGLY,
THAT THIS TYPE OF PROBLEM BE DIRECTED TO YOUR EXECUTIVE, This is one of the major .
reasons for its existence§ to speak for the amateur a-fc -the proper level.
The You-th Radio Scheme is doing an immense amount o£ good. with young people
and many s-tuden-ts have passed. and. received the various cer-bifica-fces -bhroughou-fc -fche
year. I relieve the YES to be one of the mos-t powerf 1 influences in which -the
Insti-bu-be should par-fcicipa-te fully. No-b only does i-t in-beres-t young people in a
h.oTa'by, Tau-b i-fc also serves a most useful purpose in a sec-tion of the normal educa-b-
ional system.
Operations in con-bes-ts is a valuable -braining ground, for amateurs who, at
some -time, may be called upon -bo serve in -the communica-tions branches of -the Aus-t-
ralian Defence Corps. As oon-t s-b ac-bivity is on the d.ownwards trend, it may 'be
well -to -bake a look a-t -the si-fcua-tion -bo find. ou-fc why. Are we -tired of con-fces-fcs?
Are there -too many con-tes-ts? Are our contest rules too complica-bed? Is our publicity
not good enough? Or is i-t -bha-fc we jus-t can'-fc -be bo-fch.ered? Wha-fcever •the reason, I
believe correc-tive measures mus-t be t. aken, foi? no-b only does i-t provide -training
measures, but i-t also provides T3and. occupa. ncy; a ma-tt. er v/hich vitally conc.erns all
aountries in which ama-teur radio flour'ishes Tsec.ause i-b assists materially in -the
preservation o£ our fsequencies.
The most vi-bal ma-t-ber in any clul3, society or institution is its membership.
Al-bhou-h not spectacular, I am pleased -bo report t'ha-b according -bo figures availalsl.e
there has been a modes-b increase in membershi in all divisions except VE4 which
showed a decrease of 34 members February '65 -bo '66, Of a total of 5082 licences
now issued in the Commonweal-th., i~b is interesting -bo rec.ord -the comparison between,
full and limi-ted licencees:-

Total 3808 1274 5082
From the above figures it will be noted that the limited licencees comprise
nearly 25^o of the -bo-fcal licences issuedo. If the decline of applican-bs taking the
C. W. -best proceedB a-b the present rate, I can only see grave danger ahead for the
future'retention of •the bands 3. 5mc/5 to 30mc/s. 'I believe, -therefore, -that Div-
isional councils should vigourously campaign -to encourage the holders of Z calls
to take the morse code test o
The future of -the Amateur Service all over th-3 world is far from being as
secure as individuals might think, and the Ins-bi+ute will require far greater funds
in the future than i-b currently holds if it is to successfully represent the Amateur
Service in the Australian section of Region III, For -this reason I believe that the
funds accrued by the Executive in its trading activities, should 'be used for major
future projects such as Region III conference of I»A. R. Uo Societies and other
activities of this na-fcure»
Activity by ama-teurs on all bands appears -bo have shown an upward trend
other than in contest pariicipa-tion. This is probably due to gradual improvement in
the sunspot cycle conditions which are reported -bo be clim'bing ou-fc of -the "-trough".
T-fco certificates for 'short wave listeners were coKLple-bed this year', the
SW^ DXCC AWAED a^id the HEARD ALL VK GALL AREAS ( HAVICCA ) Award. After all the
complaints aired by SWL's a-t the delay in producing these awards, it is rather dis-
heartening -to find that -bo date only two applica-fcions have been made for the DXGC
award and none for the HAVKCA.
The Publications Committee continued its usual efficient -beam work in
publishing Amateur Radio, and i-t is interesting to note that the magazine received
credit in an R. SoG. B. publication,
You will find in the near future -^ha-fc due -to -the high failure rate of
applicants si-fc-bing for Separtmen-bal exams, , • these examinations (including Amateur
certificates) will be held only twice yearly.
As Federal President of -this Ins-bi-bu-be I am more -than happy to knov/ that
•the loA. R. U, is rising in defence of the amateur service, and i-fc behoves this
Institute to back the lo A. R. U. effor-fc with. everything it has.

-besting facilities are being arranged with the aiepartmen-b of Supply,
and corn anies in Australia will be asked -to donate components. The launch is being
arranged by Project Oscar Inc., California, U. S. A.
When launched, Aus-tralis is expec-bed -to go into a circular, near-polar
orbi-b 500 miles high. Provided the package is ready for shipmen-b -bo USA in Septemtier
a launch could be arranged before Christmas o The commi-b-fcee of Project Australia
will appropriate funds to the engineers as well as making decisions concerning the
project.
The command sys-fcem comprises an Ho li'o and V, H. Fo beacon. The command
system for the former is classified information, as close control is desired over
the high powered beacon, but the latter is commandable by any amateur s-bation
capable of radia-bing about 1 kw,, e. r. p. This V. H. F. 'beacon will control some tele-
metry function to be decided later by the Australis Gommi-fctee. There will also be a
receiver in the two metre Amateur band.
The HoF. 'beacon will be commanded by -three primary tracking sta-tions
around -the world. Wi-tb a power of 250mw in the 10 metre amateur band, i-b will send
G. W. wi-bh -the gree-ting of -the V. H. F 'beacon gated in every 10 sees.
The sa-telli-te will be capa'ble of eight channel -telemetry, sequentially

PROJECT AUSTRALIS (con-b.)
After the Federal. Convention, a meeting wi-bh'-the lads from. MUAS was arranged
and a time sohe.dule worked out for the whole operation, based on the assump-fcion •fcha'b
a launch would take place at the end of -the year. When time was allowed for -testing
(in the USA. by the Oscar people), transport -fco the States, -testing at WRE and
testing at the University, it was apparent -that the "package" would have to be
complete by mid-July. In April, a report on the progress of the unit showed that the
2 and. 10. metre -transmitters were already developed and pro-totyped, four of the eight
telemetry channels had been proto-typed, and the " VK " keyer and command receiver
were still on the drawing.-board. It was emphasised -to -the group -bha-fc •they were
working -to a tight schedule, and a formal fortnightly progress meeting was arranged.
A balloon flight had been arranged to -best the four channel •telemetry system,
and on Sunday 1st May, -this test flight -book place. Ignoring as irrelevent some
problems (the me-fco balloon valve did not function and -the 'balloon burs-fc a-t 100, 000f-b.
instead of maintaining' thi.s height for a period, as was intended) the -tes-fc was
reasonably successfully. completed,, After about one hour, the system locked onto one
channel, and from data , this appears -bo have been due to bat-tery failure. Those in
authori-fcy are reasonably certain that this system is a "goer".
On Sunday 15th May, ano-ther balloon flight was scheduled to -best -the 10 metre
transmitter^ no info. available. Edo ) and around -bhe 25/26-fch May, Tonkin and Mace
were to visit WP-E, Salisbury; to obtain the latest information on methods of con-
s-truction, preferred, componen-fcs and test facilities available.

If you have no duck'bill pliers or flat longnose -type, or the ones you
posess are not suitable for uss as a heat-sink when soldering transistors, try -this.
Procure an alliga-tor clip, utilux type Ma47 - "this is a long nose -type with an
extended back lug to slip over test prod. Find a scrap of copper or brass about 14
guage, and shape to fi-fc on the end of the clip, each jaw. Finish about 3/8 and 1/4"
wide and hard solder -to nose of clip. If you v/an-fc handles get a piece of 1/8" or

Mother handy tool for removing hard-to-get-at components. Get
an extra bit for your soldering iron - flatten the point, and gash the now flat
end using a junior hacksaw blade, for about 3/16" lenghwise. Spread slightly with
a screwdriver, clem and tin in the usual fashion. You now have a ha^idy tool to
