8.33Khz? Sporty's SP200
If you think Oz is going the 8.33Khz route, then the Sporty’s SP200 transceiver may be suitable. It will probably be the cheapest approach to the new frequency spacing. That assumes someone imports it, or you can get it shipped.
I’d agree with the posters above, it’s worth getting a transceiver as opposed to a scanner. I’d just ask that you keep it away from children / drunken mates, who might want to talk to the aeroplanes…
Safe Flying,
