Which Frequency to Use
A simple rule of thumb for which frequency to use is as follows:
The higher the sun the higher the frequency. The lower the sun, the lower the frequency. For example, midday, use 5360 kHz or 5300 kHz. At night, use a 2 MHz frequency (eg 2280kHz).
The primary day-time frequencies are 5300kHz (northern half of the State) and 5360kHz (southern half).

HF radio can be fickle. A frequency that works well today may be completely un-useable tomorrow. Phenomena such as solar ‘sunspot’ activity and electro-magnetic interference from car ignitions and power lines can adversely affect radio waves. Even severe weather conditions can affect reception.
Persevere, and if all else fails, wait a while and then try again.
