Newby question
 

I often hear that SW is better received during the night hours, Does this
refer to the night time of the receiving station or the night time of the
transmitting station. I am in New Zealand and we are 12hours ahead of UTC.

Cheers

Hi Chris -- day an night propagation depnds on the bands (frequency)

Evample at 7 MHZ the D-Layer severly attenuates signals
but at night the D-layer dissaptes and you can hear signals world wide.

On the other hand -- signals around 21 MHz are best heard during the day --
usually not at night -- but during the peak of the solar cycle -- may well
extend into the wee hours.

So suggest you read about propagation -- see URL:

To be simplistic, the sky between the transmitter and the receiver need to
be dark for best reception. That is, on the East Coast of North American,
European stations are best heard after sunset on the East Coast (while
Europe has been dark for several hours). And on the West Coast of North
America, while it is still dark in the morning, SE Asia comes in best.

Thanks guys, I think I understand a little better.
To get really great reception then both transmitter and receiver need to be
working during the night hours, and this is better than if the transmitter
is in daylight hours and the receiver is in the night hours or vice versa. I
also note that sunspot activity also plays quite a big part on great
reception.

An analogy would be to think of a beam of sunlight shining through
a complex glass vase on a table in the corner of an L shaped hallway.
The places down the dark end of hallway that get lit up depend on uneven
ridges and edges and patterns of the glass.

Hi Chris

I find that after 5pm local time is good at the moment and gets better
later. We are 13 hours ahead at the moment with daylight saving.
