Aussie callsign options...?

[VK3RX]

To quote from my 1978 version of the P&T Amateur Operator's Handbook:

Amateur stations who are moved from State to State in their employment and normally remain at each address for long periods, on submission of suitable evidence, may be allocated a call sign from the following series:

then goes on to list the various "C" three letter suffixes allocated to each State, eg. NSW VK2CAA-VK2CBZ, Victoria VK3CCA - VK3CDZ etc.

Hence mine was VK3CDI and when I transferred to Tassie for a few years I used VK7CDI.

I recall from the early 80s they stopped the practice, and anyone could then take out a "C" series call sign.
