Vintage Radio
By RODNEY CHAMPNESS, VK3UG
Ray Kelly and the HRSA
The Historical Radio Society of Australia (HRSA)
is the national association of vintage radio
enthusiasts in Australia, with approximately 1100
members. It is by far the largest group representing
vintage radio enthusiasts in Australia. Ray Kelly
was instrumental in its founding and continues to
be a crucial member to this day.
In the late 1960s and early 1970s,
some Australians came to realise that
we, as a nation, were destroying the
records and artefacts of our nation’s
history and heritage. For example,
old sailing ships were left to rot, to be
burnt or dismantled. “They are useless, so let’s get rid of them”, was the
attitude of most people at that time.
Many other aspects of our history
were also considered irrelevant and
many references and physical examples of those aspects were discarded
if not destroyed. However, there were
enough people throughout Australia
who could see that this was totally
wrong and our history and heritage
was worthy of retaining and restoring,
so they set about raising the level of
interest in our past.
Our radio heritage was also being
lost at an alarming rate, with most
superseded and defective radios ending up in the local municipal tip after
being replaced. However, a number
of individuals decided that our radio
heritage was worthy of retaining and
set about collecting and restoring old
radios. Doing this in isolation is not
very effective as there is only so much
any one person can do. One person
on their own cannot know all there
is to know, or needs to be known, to
preserve a representative offering of
our radio heritage.
A small number of collectors became known to each other and communicated on an ad hoc basis. Len
Davenport in Alice Springs was keenly
interested in vintage radio and even
established his own museum in Alice
Springs. Called “The Magic Spark”, it
attracted quite a lot of interest until
Len’s death, whereupon it was closed.
However, some time before his death,
Len was keen to see the establishment
of a national radio society. He believed
that Alice Springs was not suitable for
the activities of such a group.
Len and Ray Kelly could see that
there could be room for a national vintage radio association. Ray contacted
Morris O’Brien in San Remo to obtain a
list of people who had obtained valves
to restore old radios. Morris used to
advertise valves for sale in magazines
such as Radio & Hobbies, so he had a
good contact list. Ray contacted the
people on that list, as well as the list
supplied by Len, a total of around 35
people.
There were sufficient replies from
around Australia to warrant convening a meeting, held at Ray’s home in
Melbourne on the 17th April, 1982.
The HRSA was born on that day, with
Ray taking on the position of Secretary
and member number 1. The initial
membership was 25.

Without Ray’s enthusiasm and
drive, the HRSA may not have been
established or it may have been delayed for some years, during which
much of our irreplaceable radio history

may have been lost. Ray’s life history
itself shows why the HRSA got off to
such a good start.
Ray Kelly was born in Cessnock,
NSW, in December 1920 and spent his
formative years there. At school, he
obtained sub-intermediate standard,
which was quite a high standard for
the 1930s. His interest in radio started
when he built a crystal set as a 12 yearold. In fact, most young lads started
by building a crystal set. They were
the cheapest radios to build and cost
nothing to run. Their reception range
was limited but Ray put up a good
enough antenna and earth system so
that several stations were received.
Neighbours and the local radio shop
(though they weren’t always aware of
it) helped this enthusiastic young lad
by supplying him with valves and
other odds and ends. The radio shop
routinely threw out valves that they
considered unserviceable and Ray
“rescued” them from the rubbish.
Over the next few years, he was to
build one and 2-valve sets and ultimately, a 7-valve superhet receiver,
as described in an issue of Wireless
Weekly in 1933. As Ray remembers
it, the set had an RF stage, autodyne
converter, a 175kHz intermediate frequency amplifying section, a 55 as a
second detector and audio stage, and
a pair of 59 valves in push-pull. It was

a popular, good performing receiver,
as Ray remembered it.
On leaving school, Ray started work
as a telegraph messenger at the Cessnock Post Office. This was a temporary
position and when he turned 16, the
only opportunity to join the permanent
staff was to become a male telephonist
at the West Maitland telephone exchange. This was a manual exchange
employing around 25 women as tele
phonists. However, the PMG did not
consider it right for them to work
through the night so they employed
young men to man the switchboard
from around 10.30pm to 7.30am.
On alternate weeks, the young men
worked a short shift with the women.
“At the age of 18, perhaps they were
considered a hazard to the ladies”,
according to Ray, so they were given
other jobs and Ray was transferred
back to Cessnock as a postman.
RAAF enlistment
In 1941, he saw an advertisement
in a paper for enlistment in the RAAF
as a radio mechanic. He believed that
his interest in radio should be of value
when he applied. He was accepted
but he found that they really wanted
people to learn about the very “hushDecember 2005 99

hush” radar, not radio. He trained at
what is now called RMIT in Melbourne
and then at Richmond in NSW.
The RAAF subsequently sent Ray
to postings in Australia, New Guinea
and several of the Pacific Islands.
When he was on Goodenough Island
(between us and the Japanese!), the
operators could detect the Japanese
aircraft about 130km away, soon after
they took off from their base.
The radar had a range of up to 130
miles (200km) and they would track
the Japanese planes and alert Australian forces on the mainland of the likely
target of the Japanese attack, via coded
radio signals. As a result, in many
cases, it was the Japanese fliers who
were surprised and not the Australian
populace. According to Ray, the Japanese never woke up to the fact that the
Australians had very effective radar,
which in fact worked better than the
American radars of the time.
After the war, he was sent back to
the post office as a postman; not quite
the job for a keen and experienced
radio/radar man. After some months,
he got the opportunity to go into the
telephone section of the PMG. Back
until the early 1970s, the post office
and the telephone system all came
under the control of the PMG (Postmaster General’s) department and it
was possible to shift between the two
sections of the organisation.
The opportunity then presented
itself to apply for the radio section of
the PMG. During the war Ray had met
his prospective wife and in 1947 they
married. At this time, Ray obtained a
position at the ABC radio studios at
the corner of William and Lonsdale
streets Melbourne. He worked as a
control booth operator (CB operator)
and later in the recording section,
dealing with disc recordings. This was
before the era of tape recorders, which
did not achieve any real quality until
the mid-1950s.
Acetate recordings were difficult to
make. There was only one “take” when

making the recordings so you had to
be right first time, whether you were
the artist or the technician. Most of
the radio serials in the 1940s and 50s
were on 16-inch transcription discs.
In addition to the recording work,
Ray worked in what was called the
switch-room where the programs
were switched between studios, land
lines and transmitters. A stint in the
PMG Material Testing Laboratory also
proved to be interesting for Ray.
Radio Australia
Around 1950, Ray got a promotion
to Radio Australia at Shepparton,
where he was a shift supervisor. At
that stage, there were three transmitters
which were labour-intensive to run
and operate. Each shift consisted of
five people, as these transmitters were
not frequency-agile. About 15 minutes
was allocated for the five on shift to
prepare a transmitter for operation on
another radio-frequency band. Coils
and capacitors for each stage had to be
changed, a fresh crystal selected for the
radio frequency oscillator and a fresh
antenna selected, if need be.
Today, at Shepparton, a total of two
minutes is allowed for antenna and
frequency changes for up to three transmitters at one change, with perhaps
only one operator in attendance.
Ray’s wife did not like the amount
of shift work involved at Radio Australia so, after about five years, Ray obtained a position with the Australian
Broadcasting Control Board (ABCB).
While this didn’t involve shift-work,
it did involve trips away from home

for extended periods. Ray stayed with
the ABCB until he retired on health
grounds around 1976, three years after
the death of his wife Betty.
Ray had many interesting jobs in
the ABCB, doing field strength tests on
broadcasting stations, station inspections and field surveys for new stations, all of which was very interesting
work for an enthusiastic radio man.
Ray remembers that it was usual to
notify a radio station of an impending
station inspection. Often the inspection would be made and all would be

working well. But after the inspection
had been completed, the operators
would take out the new valves and the
old weak valves were refitted, to wring
the last bit of life out of them.
Spot checks would have caught
many radio stations with equipment

levels!

television station transmitter was done
near Cairns in Queensland, where access to suitable mountain tops was not
possible by road or track. To do the

The medium-wave A.G.E Bandmaster Duette receiver was manufactured
by AWA around 1935. It used an identical chassis to the model 28 “Empire

tests a DCA aircraft was hired and a
100-watt VHF transmitter fitted to it.
A monitoring receiver was used at a
number of critical spots over a period
of time and the transmitter was left
running while the aircraft flew over
the top of the mountain at 500 feet.
When the mountain was being crossed,
Ray called the monitoring site to take
a signal strength reading.
This was a ground-breaking procedure in Australia at that time but has
become more common now as it saves
time and money. Although the site
proved to be excellent for a television
transmitting station, access was so difficult that it was not used.
Ray’s collecting history
Around 1972, in the course of his
102 Silicon Chip
work with the ABCB, Ray Kelly inspected 3BA Ballarat. It was the station’s 40th anniversary and there was
a display of sets from the time of its
inception. The station operators had
advertised for old radios of the era and
many listeners provided them with
suitable sets. This sparked Ray’s interest in the collection and restoration
of old radios, although this remained
dormant until after he had retired from
the ABCB.
Ray seriously started to collect and
restore sets from around 1978. He
visited auctions and other sales and
bought many sets at quite low prices,
although some sets did require digging
into his pocket rather deeply. His initial and continuing interest was and is
in 1920s and 1930s receivers and old
speakers, particularly horn speakers of
which he has quite a collection.
Ray’s favourite set is an AWA Radiola 45E Console from 1931 which is
a TRF with two RF stages, detector/first
audio and audio output. Other favourites are a “Buddha Speaker” (which
although not completely original is
nearly so), a tapestry speaker and a
circa 1905/7 Ericsson wall telephone.
The photographs accompanying this
article show many rare pieces of radio
history that he has collected.
But while Ray Kelly is still a keen
collector, his main activity over the last
20 years has been the HRSA. As noted
above, he was the inaugural secretary
of the HRSA and he did take his turn
as president later on.
Over the 20-plus years that the
HRSA has been in existence, he has always been highly involved in the running of the association and providing
information to members. He has been
a technical editor for the newsletter
for many years and provides copies of
circuits to other members. Ray must
have the most extensive collection
of circuit information of any vintage
radio buff.
He was also the editor of the Newsletter which was produced four times
per year, commencing in July 1982
with seven pages. It was produced
using a Gestetner machine (does
anyone remember these rather messy
machines)?
By 1985, it was an A5-sized publication of up to 24 pages and was
being produced on a typewriter and
then copied; computers were not all
that common at that time. In October
1994, the Newsletter was succeeded
by Radio Waves, an A4-sized magazine
which typically has 40 pages.
To further assist HRSA members,
Ray compiled about 12 books of circuits and other helpful information for
vintage radio collectors.
Summary
Ray’s life outside of his family has
revolved around radio and television.
He enthusiastically embraced each
new technology and experience in the
field of electronics as it came along.
He has also made sure our important
Australian radio heritage has not been
lost, hence his contribution to vintage
(heritage) radio is well recognised by
his peers. Ray Kelly may not consider
himself the father of the HRSA but

many do.
