TRANSMITTER RESTORATION
I acquired this hand-crafted ham transmitter from an on-verge rubbish skip (dumpster).
It was located outside the QTH of a recently SK'd O.M.
I couldn't quite work it out, many parts were missing, devoid of any labelling, crystal frequency would not multiply into any Amateur frequency assignment.
From the LC tuning circuits I feel it was either for 28 MHz or 52 Mhz, and probably dated from mid 1950's
(pre TVI days, Television not starting in Western Australia until Oct' 1959)

However (Aug 2012) from this web URL http://www.vk6uu.id.au/vk6hk-history.html we read:-

A few thoughts about Early VHF activity in VK6 By Don Graham VK6HK
I canít speak from personal experience before my VHF SWL days from 1948,
but word has it that there was significant activity on the then allocated 56 MHz band pre WW2.
Transmitters were often of the AM modulated oscillator type with superregenerative receivers.
There were exceptions; one I know about was the crystal controlled AM transmitter of Jack Gabbertas VK6GB (SK).
After WW2 Jack resurrected this tx from the care of the Post Office
whence it had been quarantined during the war and retuned it to 50 MHz.


The complete unit was disasembled, rebuilt and repainted;
as a Xtal controlled, Hi - Level modulated, 150 watt AM Transmitter for the 40 metre Amateur band ( 7 ~ 7.3 MHz)
Overall cabinet dimensions are 1600mm (H) 500mm (W) 330mm (D) on castors as it is quite heavy!
