Ive got my hands on something a bit unique. Its a Traeger Flying Doctor Radio.
This one is a Number 701, Type 43A6. From info in Rodney Champness' book, the type number puts it as 1943. I have the matching speaker and microphone. This one is 6V Vibrator powered.
The outer case is a bit weathered/aged but as you can see the chassis is perfect.
This one has 9 valves (1J6G 1K7G 1L5G 1K7G 1M5G 1C7G 1M5G 1K7G IL5G)
For those unfamiliar with these radios, transmit frequency was selected by a plug in coil/crystal system.
Usually two coils were supplied. one on 2020kHz, and a second one around 4000kHz depending on what base was targeted. This one only has the 4630kHz (64.7m) plug in.

Receive was more conventional with a tuneable broadcast/short wave radio, so it could be used for entertainment when not talking to the Doc.

It should restore quite well when I eventually get around to it, the only thing I can see wrong is the aerial post is missing.

Nice one There are $12 frequency generators on eBay now that can put life back into
crystal channel radios, but for frequencies so low, I think you’d have to make one.
That’s if there’s any point to using the transmitter.

If you have a ham radio licence that allows you the ham HF (shortwave) bands, you could put it on the 80 meter ham band. AMers are found around 3.88MHz in the USA, looks like that would be out of band in Australia. But it looks like 3.690MHz is the AM Calling Frequency in Australia.

Aagh!! You LUCKY man!!!

What a great find! Do you have any Provenance with it or did it turn up at a junk shop or somewhere? Something like this would have great stories to tell!! I once saw a a great display of various types at the RFDS in Alice Springs.

I have been looking for an RFDS radio since before I was born!!! (?) Back in 1988 someone with family near Warialda had one lined up for me, but it got nabbed!! I'd actually like a CW one with pedals but anything would do!! I'll probably find one the day after I've sold my collection, when I'm ninety !!! Enjoy! (Hope you don't need to use it to call the Doc!!)
