FR TRANSCEIVER INCORPORATING A MICROCOMPUTER
CPU control with ICOM's original programs provides various operating capabilities. Frequency control, band-edge detection, and the
display amaccomplished bythe microcomputer. The 5-channe! memory is controlled electrically by the use of a 256-bit RAM area. The
circuits fry these IC·255A functkms are equivalent in capability to conventional circuits having a large number of C·MOS MSl's.

MULTI-PURPOSE SCANNING
Memory Scan allows you to monitor five different memory channels. Program Scan provides scanning between two programmed
frequencins. Adjustable scanning5peAd. Auto-stop stops scanning when a signal is received, or a frequency is not being used.
SUPERIOR RECEIVING CHARACTERISTICS
The use ol newly developed fow•nolse and large dynamic range junction FET's (for the RF amplifier and the first mixer) and of helical

This month's notes will be very short and will mainly be a
calender of future events; Firstly,the Southern Branch thanks the
Northern Branch for hosting TARC ; which was enjoyed thoroughly
by everyone who attended,
At the next General teeting,topics to be discussed will
include ;
(a) A club project for 1980 of a general purpose UHF
repeater for TV and TT,
(b) Nominations for Amateur Advisory Council.
(c) Any early nominations for Febuoary elections of the
Southern Branch ; these must be in prior to the
commencement of the February meeting
(d) Southern mini-hamfest ; Bruny Island 23 - 24th Feb.
Part II of the video tape Aerial Circus G6CJ will be shown
during the second half of the meeting.
The swap shop stand will again be operating.
The next General Meeting will be held on February the 6th at
SES Headquarters,with the executive meeting being held on the 3lst
of January.
The Divisional AGM and Dinner are on the 15th of March in
Hobart and arrangements are well under way for this.
The wine bottling and barbeque to be held at Tom (7TM) and
Gael's QTH is the Christmas function and this is to be held on
December the lst.. It is a BYO drink and meat with salads,savouries
etc,being provided.
The Repeater hos had a holiday recently,due to damage to the
receive antenna cable.This cable is very delicate and must be gently
treated ..However,due to forces unknown,it was damaged,resulting in
intermittent shorting of the two conductors.On the second climb,
Andrew,VK7 cut the cable and replaced the connector with a new
one,We hope that with the connectors costing approx 40 dollars each
when available,not to have to repeat the exercise.
While this tower work was in progress,Brian,VK7RR retuned the
transmitter,replacing the final valve with a new one and also
retuned the receiver for good measure.
Incidentally,I was mobile in VK2 about three weeks ago and
worked a number of newcastle amateurs who have recently heard the
Southern repeater,That is one way to keep up with local news when
you are away.
Happy Christmas all: and may the Christmas spirit not
cause your harmonics to be in discord,cause all projects
to oscillate in sympathy and may the New Year find all
safely through the festive season. 73 Sue

Council Elections
The next QRM will contain a nomination form for Divisional and
Federal councillors.I guess the Divisional Council is rather a remote
body for many new members.It is often difficult to find items of
general interest from council meetings,to report in "QR"each month.
Suffice to say that Council is a co-ordinating body between Branches
and between the State and Federal organisation
If you feel that you hove skills of use to your fellow amateurs
in this orea,then please offer your service.Representatives are
needed from each branch and our constitution ensures the election of
a Novice Licencee.
Current office bearers are ; President Ian Nichols,VK7ZZ
Secretary Paul Blake VK7ZPB
Treasurer and
Alternate Federal Councillor Peter Frith VK7PF
Federal Councillor Reg Emmett VK7KK
Councillors Graeme Johnson VK7GD
Paul Waller VK7PA
Paul Wagner VK7NEA
Amateur _Advisory Committee Branches are also receiving nominations
for this committee.It acts as a liason between the Amateurs and the
P&T Department in self-policing our bands.let us know if you can help.
You would need to be able to spend sufficient time to carry out a
regular listening schedule.Meetings are held bi-monthly,in Hobart,
on Saturday afternoons.

TASMA«IAN AM4TU? RADIO CONVENTION 1979
This year's Convention at Alanvale College in Launceston on
the 17th and 18th of November, appeared highly successful.One hund-
redd»fifty attended for lunch on Sunday and a similar number of the
general public looked in on Saturday.
Once again on impressive array of commercial equipment was
on display.However an apology is tendered on behalf of a few
exhibitors who were forced to cancel their contribution at the
last moment.,
Provision of workshop sessions seemed quite poular and our
thanks to those who assisted in this area.
The new style foxhunts,provided plenty of exercise.As the
fox was placed in an 8cm by 20cm tube,a wide variety of hiding
places were possible.Fox hunt prizes were awarded to :
Tony Pollowy VK7TP (1st) and Graeme Reardon VK7ZG3 (2na)
It seems that the art of home-building of equipment is not
yet lost,judging by the amount of home-brew gear on display.A
wide variety was on display and prizes awarded as follows;
(lst) Kenwood trophy end 1st prize to Tom Moffat VK7TM for his
first class exhibit of a RTTY demodulator.
(2nd) Graeme Reardon VK7ZGG for a low voltage power supply.
(3rd) Tony Pol1owy Vk7Tr for the sheer volume of his exhibit:
A table full.
-----
Activities for the ladies and children and a dinner dance on
Saturday night,attended by 97 people,completed the weekend.,
If there were any people unhappy about any aspect of the
weekend,they didn't complain to me.I hope newcomers to Amateur
radio who attended were mode welcome by the old timers.One
particularly pleasing aspect was the large number attending from
Southern Tasmania
Thanks however,to everyone for your attendance,to the ladies
for manning the canteen and providing Sunday lunch,to exhibitors
and to the committee for their work and support.In the hope that
I've not left anyone out, thanks to all who helped in any way.
To those who didn't attend ; don't make the same mistake
next year.

NORTH WEST BRANCH NOTS by Jim Vk7NCw
Before presenting the Branch notes,there are two things that
I would like to mention ;
Firstly,we are all very sorry to learn that our popular and
efficient Secretary,Joan,has been confined to hospital.However,it
is gratifying to know that she is now home and recuperating.Joan
has asked for leave of absence and her position is being capably
filled by Tony,V7AX.
Secondly,it was with some great concern,that the meeting was
informed that the great stalwart of Amateur Radio on the North
West coast ; Max,VK7MX ; advised.in writing,that he wished to
sever all connections with the branch,This indeed,is a great shock
as Max has given the Branch 22 years or so,of invaluable service.
He has been responsible through his generous and unselfish
assistance,in helping several Amateurs obtain their license;the
writer being one of them.
Max,no doubt,has his reasons for taking such drastic action.
His place is going to be very hard to fill.
Minutes of previous meeting were read and confirmed.
The Treasurers Report was presented by Ivan VK7ZOA/NOA.
December Meeting Because of a prior commitment,the headquarters
are not available on the usual meeting dote..will members please
take note that the December meeting will now take place on Dec.12th
commencing ot 7.30 local time.
QL Bureau Don,VK7NP distributed many QSL.'s.His efforts are much
appreciated by the Branch.
Council Paul.VK7ZPB,told the meeting that the Branch subscription
be i3 to cover general operating expenses.Paul advised the meeting
that he is leaving VK7 soon to take up an important position on
the mainland.
ATV Groue Tony,VK7AX,odvised that the group is engaged in
several projects and is going along well.
Microprocessor Group Steve,now V7Z??,reported that this group is
also gor,long nicely.
The Chairman advised that moves would be mode whereby various groups
would be held at future meetings to cater for the novices ;eg HF,
ATV,VHF etc .• We would like to see this eventuote,because the
novices ore increasing in numbers all the time and should be
catered for.It would be a wonderful move if,after the general
business was finished,for all those novices interested in obtaining
a poss·in AOCP theory,to go to another room to receive instruction
from an instructor,The Branch is fortunate in having several very
qualified members in this sphere.
Bob Wilson,VK7ZAA kindly donated many back issues of QST magazine.
Giant Christmas Stocking valued at $250 is being organized to be
raffled in aid of Branch funds,by Vince VK7NVH .. In order that the
general public may participate in the raffle,Vince is looking after
the Devenport area,Tony,VK7AX the Ulverstone area and Steve VK7Z??
the Burnie area.Tickets to be 50 cents each.
~.-12 Tony,VK7AX advised that he was collecting equipment to
take to Launceston to enter in the Home Brew display.Tony also
reported that the 2 beacons are now working okay.
North West Branch Notes (cont)

The Actin2 Secretar:t was instructed to send a letter to Max,VK7MX
over many him
thanking for the invaluable work he has done for the Branch
years.
J.Q.T.A. Several groups were held on the coast,Vince,Vk7NVH,
"around the world in 80 days" had bad luck with his balloon carried
antenna.The balloon hit a tree and"poof",
A group of Guides accompanied by the Devenport Guide leader and
Guide Commissioner,were entertained at the shack of Jim VK7NO\\I, On
the Saturday afternoon-right on the dot of 0700.i on 21.170 MHz,
Werner,DF4FX of Kosse] in West Germany,transmitted to us,some
superb,noise free SSTV pictures at strength S7 to S9 all the time.
The pictures consisted of greetings to the Guides,pictures of
himself and XYL,olso of his lovely home and miniature waterfalls.
One Guide spoke in German to Werner;who also speaks excellent
English •• ,On the Sunday at 0530 Z precisely,the Guides spoke to the
very popular Mexican operator,Harry,Xl-FT~, Guadalajara. Harry's
eldest daughter stayed un until 11.30 PM Mexican time,especial1y
to speak to the Guides.Se spoke in excellent English and French.
