Thanks for sharing your pictures with us Mike.
With such a selection, I'd expect to recognise a few, but they're all unknown to me!

There is a lot of HF radio used in outback Oz. Here's an informative web page ....

These are un-restored items, found in Australian outback country heritage type displays.

The early AM and SSB sets were for use by outback cattle stations calling The Royal Flying Doctor Service for medical assistance.
Then the later sets were for RFDS as well as "School Of The Air" education by station children, as well as for chat sessions.

In a previous life, I have installed and maintained the Codan 6924 backpack type SSB sets in forward bases for Search and Rescue with aviation incidents, in country where SSB voice on low HF freqs almost always got through, even with relatively low power and rudimentary short sloping wire antennas.

"Flying Doctor calling Wallamboola base" became something of a catchphrase for anyone listening to the BBC Light Programme series that ran from 1958 to 1963. The Flying Doctor was written by the Australian writer Rex Rex Rienits and proved to be a very popular show, clocking up six series and over 120 episodes.

Gud'ay!

I don't remember a radio series, just the TV series, which was on at about the same time as "Whiplash"

Same here, it's the TV series I remember, but there seems to more on-line info on the radio series than the TV version. IIRC,"Whiplash" was a "cowboys in Oz" series set in about 1850?

Is there a web site dealing with development of radio in the Outback? I've often wondered if war surplus stocks were adapted for schools and flying doctor use. Was there any point-to-point radio prior to WW2?

They all seem to be operable on three bands, around 2.5, 5.5 and 7.5MHz. They mostly look to be of the valve era but the Wagner must be solid state. Any idea where the Wagner was manufactured? I ask because there was a series of Wagner CB sets, from Taiwan I think

G'day everyone.
Interesting topic.
I personally know the Wagner and Tracker Scout radios in the pictures. I have examples of both in my little collection of radios.
Both of them are full solid state.
I think that most of the other radios in Radio 1950's pictures are solid state.
All of them are battery powered and the give-away for the solid state ones is they do not have a standby switch. There is a solid need to reduce battery consumption to a minimum so the idea of running transmitter valve filaments while just using the receiver for maintaining a listening watch. Yes there are some sets in the world that have fast heat filaments but I am not familiar with them in this situation.
Tracker radios were made in South Australia and Wagner radios were made in Dee-Why, a Northern Beaches suburb of Sydney, New South Wales.
radio comms in the outback started in the later 1920s pushed by the Reverend Dr. John Flynn (Flynn of the inland who was also instrumental in starting the Royal Flying Doctor Service (RFDS)) and on the radio side of things was Alfred Traeger from Adelaide.
Alf Traeger invented the pedal wireless.
There were quite a few small companies involved in manufacturing radios for the RFDS.
One of the larger manufacturers was the Amalgamated Wireless Australia "AWA" company. Their main factory was in Ashfield, Sydney.
One of their prominent radio setups prior to WW2 was the transmitter (3B) and receiver (C6770) setup. All valve tunable receiver and crystal locked transmitter.
During WW2 the 3B transmitter was improved to the 3BZ.
Both of these radio setups were used by the "Coast Watchers" up in the Pacific and New Guinea during the campaign against the Japanese during WW2.
AWA had a very strong association with the Marconi Company and one of the things that was used here was that the AWA radios were leased to the various users but not sold to them. Similar doctrine to the Marconi Company with their marine radios.
What this means is that not many of the 3B C6770 / 3BZ C6770 radio setups survive to this day.
I am lucky in I have a 3BZ and C6770 radio station awaiting restoration in not too bad condition.

Thanks Robert, some interesting points there that I'll follow-up on the web.

Yes, Marconi rarely sold equipment, mostly they leased out. I have a Coastal Radio 91/MX AM transmitter-receiver and researching that I found Coastal had a leasing contract with the RNLI to provide radios for all the lifeboats around the UK and Irish coasts. Marconi acquired Coastal in 1956.
