Opening on the 40 MHz band between N Australia and NW Europe - 23rd Oct 2024


A week ago on the 16th of Oct 2024, I reported on how there was an opening on the 40 MHz (8m) band from the north of Australia to the south of Europe. Conditions are gradually improving and on the 23rd of October, there was a similar opening but this time, it was from the north of Australia to the north-west of Europe. I have included a log of reports at the bottom of this post.

The map above shows the FT8 reports from PSK Reporter and the frequency is use was 40.680 MHz, the main centre of activity for all modes on the 8m band.

Mark, VK8MS in Australia was operating under the terms of the LIPD (Low Interference Potential Devices) Class Licence.  LIPD allows Australian citizens to operate on several bands in the low VHF spectrum with the need for a licence if the power output is below certain levels.

For the frequency range of 40.660 to 41.000 MHz (340 kHz), a maximum of 1-watt ERP can be used.

I have more details about the Australian LIPD licence in this previous post... https://ei7gl.blogspot.com/2024/01/low-vhf-band-lipd-licence-in-australia.html

In general, the further the path moves away from the equator, the more difficult the path. It's one thing for VHF signals from Australia to reach the south of Europe but when path opens to places like the UK and Ireland then it's worth taking note.

The key takeaway from this post is that conditions on the 40 MHz band are improving and if the maximum usable frequency is reaching as high as 40 MHz then there is a chance that an opening on the 50 MHz band isn't too far behind.
