Why not join us?
s copy of "RM" is being forwarded to all licenced
eurs in Tasmania. If you are a non member of· the IA why
not consider joining?
Perhaps the reasons for belonging are rather intangible
as you still reap the benefits of WIA activities without
being a member. Increases in band allocations, provision of
VHF be.cons and repeaters, SL services and assistance from
other Amateurs are available to everyone - members or not.
But shouldn't you offer your support?
The WIA's standing with licencing authorities and its
political influence depends on having a high proportion of'
active amateurs as members. In Tasmania we are proud that
we have such a high proportion but it can always be improved.
I guess criticism can be levelled at any organisation
but we believe that the iiIA in Tasmania is progressive and
its organisation appropriate to its needs. But more support
and ideas are always essential.
New members are always welcome at Branch meetings or
to T.A..C.
Tune into our newsbroadcasts - 9.30 a.m. Sundays, 3570 kHZ,
7130 Hz and VHF repeaters.
7.30 p.m. Sunday from Northern Branch repeater.
Increased membership helps everyone. If you are a non-
member, fill in the enclosed membership from and return to your
branch.

NORTHERN BRANCH NOTES
The last general meeting of the Branch was held at the
clubrooms on the 1Oth October. There were 30 members and one
visitor present, and this is pleasing to see.
The Treasurer, 7NC, reported a healthy financial situation
and reported a net loss of ~1.05 for the social evening at
Riverside. This function obviously ran close to budget.
General Business: There was a reminder to the meeting to
send their registration forms for TARC in as soon as possible,
as the N.W. Branch has to advise caterers.
In discussion on the new repeater on Mt. Barrow, it was
advised that the power supply and charger were completed.
Tony VK7TP offered his assistance in the project.
In a formal motion, it was resolved to purchase a L12,
10 watt linear amplifier to serve the TS120 HF rig at the
clubrooms. The quoted cost was very reasonable and a worthwhile
investment to the club.
J.C.T.A. There was no official request from the Scout
Association to use VK7NB although several amateurs from the
Northern Branch will be operating stations for the Jamboree
on the air.
FOOTNOTE: David VK7YY and Les VK7NHA operated at cots@ale,
VK7Z'iiW, Mike operated on the Wiest amar and Norm VK7TN at
Badger Head.
4RN. - In need of technical articles please.
Demonstrations: Following general business, Joe, VK7JG
gave the meeting a display and explanation of his processor
controlled RTTY set up. Andre, V7A followed with a
demonstration of his SSTV using a RCBT LOO with cassette
and camera inputs. VK7GG then provided an excellant display
of his microprocessor (CHALLENGER 1P) and its use in log
keeping. All these demos were well presented and certainly
appreciated.

There are more new stations than this but are unknown
to the writer. Congratulations to all who were successful in
the last examination.
MEETINGS AND DATES TO REMEMBER.
Next General Meeting: At the clubrooms on the 1luth November,
This will be a YHE night with emphasis on the use and function
of the repeater and other repeaters. Also explanations of
VHF Dx, something all the newer stations should be interested
in. Remember that there is more to 2 metres than FM repeater
operation. VHF is a big field but also very enjoyable.
Get-together; Great Northern Hotel
See you in the tram on the 1st floor on the 28th November.
To those of you who have missed the first two such nights,
please come along and discover what a friendly and relaxed
evening it is. Stay for as little or as long as you like.
See you there.
December General Meeting:- 12th December.
This will be a BYO BBQ with little or no business. Either
cook your tea or just come for a rag-chew with glass in hand.
BBQ will be set up at the rear of the clubrooms in the reserve
area,
73 Ken Kirkman VK7KT
To all these VK7 Stations who have operated on "Open House"
Comes a very special thanks from the many overseas stations
who have been able to contact the elusive VK7.
"OPICAL TOPICS"
Your scribe was asked the other day how to measure the
height of a building with a multimeter.
Being of a non-technical nature, I suggested that one
should climb to the top of the building, tie one end of a
ball of string to the multimeter, let it drop to the ground,
then measure the string which would give the height of the
building.
However, Ellis, VK7WA has come up with a technical way
of doing this, using a multimeter.
If anybody else has any ideas, send your info to the
Editor.

LEER TO TH EDITOR
Dear Sir,
In reply, to the letter by Bob VK7NRH on page 7 of the Oct.
issue of 11QRM", I would like to agree with Bob, that a State-wide
relay on 2 metres would be just fine.
This however, would preclude the many novices in the State,
to give their opinion of the broadcast on the 8 metre call back.
I don't know what type of antenna Bob uses, or where his
QTH is, but I think perhaps, he would be one of the few VK7's who
does not receive a good broadcast.
If the 80 metre relay is poor because of ~RM, QSB etc, then
he has recourse to 40 metres or even 2m.
Whenever the broadcast is originated in the south or north,
I have no trouble in receiving the transmission perfectly.
When the broadcast is originated on the coast, the lO metre
signal is heard all over the State, the 2 metre relay is
excellent, and according to all reports that I receive on the
80 metre call back, my 80 metre signal is received reasonably
well throughout the state.
During the next 2 months when the broadcast is originated
in the south and north, I will make a tape of a short transmission
taken from 80, 40, and 2 metres, so we can then evaluate what
the various transmissions sounded like over a period of 8 weeks.
Perhaps, until the new northern repeater is operational on
Mt. Barrow - when a state wide hook-up would be quite feasible,
Bob may like to help with the relay of the Sunday broadcast.
Yours faithfully,
, Davie VK7NOW

SOUTHERN BRANCH NOTES
The day/weekend at the Lagoon of Islands was a great success -
even the weather smiled upon us - and a good time was had by
those members and families from the North and South Branches who
attended. It was difficult to ascertain numbers due to the
frequency of wandering harmonics, but there were probably close
to fifty present. Amateur radio even came into use to help the
boys in blue, with satisfactory results.
Southern branch members were saddened to hear of the death
of Ted Cruise, VK7EJ on Thursday the 8th of October. Our
condolences go to his family.
VK7IF and XYL Jenny have left Tasmania last week for
holidays overseas including Japan and America. Have a good
time, Jenny and Ian!
Business arising from the latest S.. executive meeting
include the following topics:
The 6m. beacon is awaiting approval from the P & T Dept.
before becoming operational from its newest site - the TCAE;
this approval is dependant on some correspondance, and is
expected very shortly.
The s.B. QSL cards have been printed and are now available.
is in the process of being purchased by the s.B., this
li > for loan to members once bought.
•:3tore is awaiting the delivery of a large number of
books, some of these have been on order for some time, and are
expected to arrive shortly.
Due to the rationalisation of SES, it appears that the
building may have to be vacated by 10 p.m., which could create
difficulties with our monthly meetings. The question of
Clubrooms is to be gone into yet again, so any suggestions,
please let any clubroom committee or S.B. executive member
hear them.
A Christmas hamper is to be raffled over the next couple
of meetings, so members are requested to bring to the next
meeting an item from the kitchen or failing that, the shack.
(I have to pack it all up into a giant stocking, so no
excessively heavy/huge/perishable items please.) The Raffle
will be drawn on Sun. the 7th December at the 'ivags barbecue.
The next S.B. meeting will be on Wednesday November 5th.
at the SES rooms in Melville st., starting at op.m.
The next S.B. executive meeting will be held on Thursday,
November 20th.
The GS barbecue will be held on Sunday 'December 7th at
the Waterworks reserve; the cost will be $1.00 per person/family
to cover costs of bread, salads etc. BO meat and alcohol.

The Handicapped Aid Programme aims to introduce to Disabled
and Handicapped Persons, radio whether it be SL or amateur.
As there are problems for those with disabilities, to
operate and maintain most common makes and models of gear
can be difficult. Therefore, those who would be interested
in assisting in this area are invited to contact me at 5
Helen Street, Launceston 7250.
This is also open to anybody wishing information about HAP.
As part of TARC '80, there will be a meeting of those wishing
further information about these areas and about the Programme
in general. This has been scheduled_for Sunday 23rd. of
Novemoer at 11 a.m. at the Penguin Hi.o. I look forward to

WICEN NOTES
Training Course,
On Saturday September 13th a WIGEN training course was
held in Hobart. Fifteen members were introduced to the formal
message-handling procedure asused by s.E.S. and by WIGEN
throughout Australia, and then given the opportunity to show
what they had learned during an exercise on Sunday afternoon.
The course began at 9.15 a.m. (on time! and after an
introduction by VK7AW, sessions on Message Writing and Formal
Message Handling were led by Brian Brand, Southern Regional
officer, S.E.S. After morning tea Col Hocking, Training
Officer S.E.S., took a session on the requirements of a
Signals Centre, ranging from a simple one-man operation
up to a full-blown headquarters situation.
Most participants enjoyed a counter lunch at the nearby
Black Prince Hotel, and following this, VK7AW outlined details
of insurance cover for members while on exercises and
emergencies, also of callout procedures. Col Hocking then
gave a brief session on Map Reading - normally a weekend course
on its own. VK7R revealed the long lost VK7RHT repeater
coverage map during a session on VHF propagation and repeater
coverage; this was followed by the Course Summary and
Briefing for the Sunday exercise. Proceedings were concluded
by l.30 p.m. (also on time.)
On Sunday (September 1buth) three separate portable HF
stations were established: one at Clarence s.E.S. H.Q., with
outstations at Glenorchy (Tolosa St., reserve) and Oppossum
Bay. Prom 2.00 pm. until 3.30 p.m. a steady stream of
exercise messages was maintained between the stations,
relating mainly to storm damage. All messages were sent and
received using the procedures learned the previous day, and
the on-air performance was very good. All participants sent
and received at least one message; the messages were pre-
prepared on standard SES message forms, and were completed
by the operators (sending and receiving) with details of when
the message was sent, by whom and over which system (HF).·
At the conclusion, a brief summary was given. The main
points arising were:
(a) some operators were speaking too quickly;
(b) some unfamiliar words were not spelled out, resulting
in repeat requests;
(c) too many call-signs were used too often - a
common amateur trait.
The exercise was all over by l.00 p.m.
From my point of view as ICEN Co-ordinator, I was very
pleased, firstly with the number attending the course, and
secondly with the performance of all participants in the
exercise. Several ideas are being considered to provide
regular practice in the procedures - one is to make every
second monthly sked a message handling exercise. If anyone
has any comments or ideas, please let me know.
QRM Page 13
WIGEN NOTES CON'T.t
Finally, for all those who took part in the course, SES
has made available copies of the Radio Procedures handbook.
These may be collected from VK7AW.
Monthlz.._Sked
WIGEN membersin the South are reminded of the monthly
round-up, on the third Wednesday of each month, 2000 hours
local, on Repeater 2 and 28-570MHz (simultaneously) WIGEN
members will be called in, as per the membership list. Wait
until you hear your callsign, then report in.
Following any news or information, message-handling
practice will take place. Please ensure that you have a copy
of a Message Form (CDF3), blank or used, handy (You should
have several from the Training Course). Also, before the sked,
select a paragraph from your ARRL Handbook which can be sent
as a message. Every station will send and receive one message,
using the standard procedure.
T,A,R.C. Involvement.
WIGEN is mounting a display at the Convention, consisting
of a static display as well as a talk and demonstration on
Sunday morning. Any members attending T.A.R.C. '80 are asked
to contact VK7AW in order that they can be volunteered to
help out.

VHF Notes.
A large Inversion around the 17th provided a lot of the "new"
calls as well as many of the "old" ones with a taste of things
to come for the summer.
With 5 VK3 repeaters being accessable for three days many FM
contacts were made both from the mobile rig as well as from
the home.
SSB activity was very sparse the VK3's being very conspicuous by
their absence. The VK3RGG beacon on 52.33 has been audable for
the past week with signals peaking to S5 during the inversion
period.
6 Metres provided some activity on the 11th with very strong
AURORAL propogation, VK3OT being the only mainland station
active. He was worked y VK7's JV ZKT and JG. Despite several
calls on R8 and R2 no other stations were heard. Around 1900
local time the following beacons could be heard VK3RGG on
52.33 VK3? on 52 .. 435 and VK2WI was 82. on 52.45. So as you can
see had there been a few more active amateurs on the band most
of' s.:s. AustraJ.ia could have been worked.
The aueno did not provide any activity in the Southern
Hemishere but we can look forward and hope great things happen
for is i1lovember. This is usually the time to work all that "RARE"
DX.On the other hand the Northern Hemisphere had a very active time
with numerous openings from i. To JA W6 to 5JAU and many more. If you
listen on 28.885 around 0830 local time you will catch up with the
latest activity~ 73 till next month Joe VK7JG.

Z.A.R.C._1980,
Besides a lot of very complex and very modern equipment
which will be on display, patrons are urged to inspect the
"Radio Then" display. Nothing quite like this has ever been
seen in Tasmania - perhaps Australiao
For instance, you will be able to hear an actual recording
of the voice of Florence Nightingale; Kenneth Landfret, the
sole surviving Trumpeter of the "Charge of the Light Brigade"
(as at 1890 when he made the record) sounding "Charge" on
the actual Trumpet he used at Balaclava.
You will also hear a Lecture by Thos. dison - and wait
for it.' A talk by none other than Dr. Lee DeForest, the
inventor of the Triude. (He has been dead for many years)
Also sounds recorded on the battle field in World War 1 -
plus more
A unique pictorial display of the 'Grap Zeppelin' and
the ill-fated "Hindenberg" will be shown, with an undulator
ink-recording of a CW message from the "Hindenburg" and
finally some graphic pictures of the horrifying explosion
as she came in to moor at Lakehurst, U.8.. in 1937.
This concludes with an on the spot broadcast by Herb
Morrison of N.B.G. news of the actual explosion. It is still
regarded as the most graphic 0/B ever made. You will hear
him cry with emotion.
l these famous sounds will be heard coming from the
audio end of a 46 year old radio - this radio is Original
in every respect.
Hi Fi fans will see (and hear) where the Radiogram
started from - 1925 would you believe.
Also, wait for it! you will hear how a radio was played
through a gramophone! This device was popular in America· in
1924.
Many historic studio mikes will also be on display,
plus a Spy-Radio used in World War II and much, much more,
Don't miss this display.

Conditions over the past month have been very spasmodic.
Early in October, there were severe ionispheric disturbances
which disrupted HoF. communications. However, as often happens
prior to one of these blackouts, long distance propagation
of signals to areas and regions not normally noted at this
time of year, did occur. WV has daily lonispheric Status and
Solar Flux Numbers at 18 minutes past the hour, and WVf'fH,
Hawaii, at l7 minutes past the hour.
Scoop of the month must be the reception of Pakse in
Laos. I heard this on approximately 6610 Khz at 1127 GM.
The programme consisted of Thai type music, then they trans-
mitted what appears to be an Interval Signal of Drums, which
preceded an I/D with a male announcer. The language sounded
as if it was from the Indochina Region, but it was not
Vietnamese. At the time I did think I had Cao Bang in
Vietnam, however, the October issue of the Australian DX
News identified it positively as being a Provincial station
within Laos. It has been varying in frequency from 6629
down to 6601 Khz. Gao Bang is now on a different frequency.
Signals ere only fair.
West African Signals were coming in very well at around
0630 to 070oz during the last week of September and the
beginning of October. The Voice of Nigeria from Lagos was
heard on 15120 Knz from 0635 to 0713 in English with their
Gen~ Oversea Service. Programme consists of News, Commentary
and Nigerian Press Opinion, etc. Signals are excellent. As
well several West African Utilities were heard: namely the
Ivory Coast Internat'l Telecomm Corp. on 11.555 Khz with
a Marker I/D in French/English on USB at 063l42. Bangui in
the Central African Republic was also noted on 15.630 Khz
LSB also with English/French Marker I/D with strong RTTY QRii
on the lower side. Listen at 0640.
Radio Nederland's DX Jukebox has a new producer/presenter.
Jonathon Marks ex Austrian Radio DX Panorama and World Radio Club
on the BBC brings the latest happenings in the world of Ding
each week. It can be heard 0750 repeated 0850 on 9.715 Khz.
Don't forget the workshop/seminar on Short-wave listening
to be held at TA.RC'80 at Penguin on the 22nd of November.
Every one, whether he is a beginner or an experienced DXer,
will find it interesting and informative. So come along and
join in on the Saturday afternoon. Well, that is all for this
month. Until then, the best of Ding and 73's Rob. L. Harwood.

This cirucit was developed to give an end of transmission
'bleep' using an easily available IC.
Gates 'a' and '' form a gated oscillator whose frequency
is controlled by the In5 capacitor and the 33OK resistor.
Gate 'c' creates a delay which controls the length of the
bleep via the O.1u and the 2M2.
Gate 'a' buffers the output; the level is controlled by
the l470K and the 15K potential divider chain.
The prototype was built on a piece of 0.1 inch veroboard
1& ins x 1 ins, and fixed inside a diecast box 3z ins x1# ins
x 1 ins. It is mounted in line with the microphone of my FT101b,
using the internal 13 volts brought out through the spare pin of
the microphone socket. •
