CAN A PIECE OF EQUIPMENT COME ??
started when I found an old transceiver on a rubbish dump on a cattle
station on the banks of the Darling River in Western NSW. It almost
looked too far gone to worry much about, but I asked the station
owners about it and they said it had come out of one of the station
barns. They couldn't tell me much about the history, but it had to be
originally used as a Flying Doctor radio, School of the Air or Rural
Fire Service. Actually, it was unlikely to have been used for the
latter. It looked as if it had been on the tip for some years and

in the 1957 Call Book as B.E. Hardinge, Natimuk Rd, Horsham, Victoria. I
would be interested in receiving further information about Hardinge
It has been
restored to a working unit, puts out 5 watts of AM and the receiver
tunes from 2 to 7.5 MHz, although I must admit that the tracking is poor
because I have stretched the high frequency end from the original 6 MHz.
It has been back on air making contacts again after all these years.

Can someone shed some
light on this numbering system?
On my unit, this
number was on both the cabinet and the chassis.
On the unit described
by Silicon Chip magazine in the October 2005 issue, a very
similar transceiver (same circuit but mechanical variations)
was called "The Harbros 12/54B. There was an earlier unit
called the 11/53M. I also note that the published 12/54B
rear panel had 413. 12V. painted on in a similar manner to
