  1. According to the ACA website, the nominal medium wave AM broadcasting band
    in Australia is 526.5 to 1606.5 kHz (inclusive). So why does Radio 2
    broadcast on 1611, 1620 and 1629kHz if (perhaps) most receivers only tune
    the above frequency range (526.5 to 1606.5 kHz (inclusive)?

    Has there been a change in the standard AM band frequency range in recent
    times?

    Cheers,

    Most AM receivers are mechanically tuned and cover a margin above and below
    the nominal figures for the AM band - 520 to 1670 kHz is typical.
    However, my Aiwa digitally synthesised AM/FM tuner only covers from 522 to
    1611 kHz, so no radio 2.

    There are now quite a number of services operating just above the top of
    the AM band - this craziness started in Sydney in late 1970s with the UNSW
    broadcasting course lectures and later 2RPH ( Radio Print Handicapped ) on
    1730 kHz. At the time few standard AM sets covered that frequency but cound
    easily be tweaked to get there. 2RPH moved a few years ago to the present
    1224 kHz.

    See http://www.2rph.org.au/default.asp for WTF 2RPH are.
