                       Efdiotorinl.

With the onset of spring, and summer to look forward to, we might
begin seriously to take up o few of the ideos thot have been
mentioned ot recent meetings.  In spite of the socialising of the
1985 TARC, there is still much to be done to bring together more
permeonently the hundreds of individucls that comnrise the amoteur
"bodv" of Tosmoniz. Last month we mentioned the need for
organising the ecsier interchenge of news; this month perhans we
could consider the organising of "outside broadcasts" - a State
Field Doy,   the    idec mooted recoutly of o     "Vox hunt",     or o D/E Rally.
All these things have been the subject of conversotions overheard
but don't seem to have progressed any further. They oll heve o good
balance of social and technicol       content,    and,    if Statewide,    would
Teguire o great deal of organisation. Our experience of the TARC
operations shows that this isn't nltogether a bad point - some
orior meetings ore often     the means whereby we can enioy one onother's
company and yet have some definite end in view.   In fact the real
aim should be to make such activities into annual events with
owards to give them kudos.
It hosn't token long for the furore of the Convention to revert to
the usual situation in which the great majority of members see one
onother only at monthly meetings.        Here,    it   seems   to us,   is one
programme which could give us all o reasonable number of face-to-
face contacts in between times.   Don't just treot it as o bit of
cloud  ocuckoo land, but set to and prepare for the better weather.
We might even persucde some of our more diffident members to come
out of their shocks ond enjov the sunshine.   From among the highly
erudite crowd of Tasmanian amateurs there may even be some other,
ond better, ideas.

               SOUTHERN BRANCH - CHANGE OF VENUE.

        Due to a change in the policy of the State Emergency Service,
    it has become necessary to find a new meeting place for the
   W.I.A.   Southern Branch in Hobart.            From Wednesday,   September 4th,
    the Branch will meet at the Elizabeth Matriculation College in
   Elizabeth Street, on the corner of Warwick Street. The time
   remains the same - 8.15 p.m. Parking is available in the streets
   around the College and the meeting room itself is approached from
   the Elizabeth Street entrance - the first room on the left along
   the corridor.  After the September meeting, it will be possible to
   work out in more detail the general organisation, such as the
   set-up for Executive meetings.
       Our thonks are due to the 5.E.5v 4oy their acceptance of our
   meetings in the past, and it is to be hoped that the present
   amicable relations will continue into the future.

have the generator reconditioned.

The CW OPERATORS QRP CLUB is a group of INTIRWATIONAL AMATZUR RADIC OPERATORS
dedicated to promoting the art of «RP ( Low power, less than 5watts output )
using the CW mode on ALL applicable Amateur Band Frequencies.

Output power to the antenna    is limited to Swatts maximum for all <RP purposes
and for JRPp the outiput nower to the antenna is limited to Iwatt maximum.

International 4RP calling frequencies are 3560:7030:I4060:21060:28060.
The Club operating freguencies are I8I5:3530:7025:I4050:2I130:28I25.
