Some years ago I enjoyed experimenting with utilities assisted earth-mode at VLF and was amazed by the range I could achieve with 5W. These results were put into a blog that is accessible via my main G3XBM website.

Operating patterns
It would appear I am a creature of habit!
I seem to go on 10m FT8 RX most of the day with a few minutes of QRP TX early on. Occasionally my QRP is spotted. More often than not, it isn't!
Just when it gets dark, I QSY to 630m WSPR RX for the evening. If I can fix my transverter I hope to TX again this winter as there seems to be fewer people TXing, but plenty RXing.
472kHz WSPR RX
At 1814z, I QSYed from 10m FT8 RX to 630m (472kHz) WSPR RX. So far, nobody spotted. I am using the earth-electrode "antenna" in the ground.
UPDATE 1943z: Still no spots.
Crystal set DXing
Crystal sets can be great fun. They are simple to make and need no power. On HF, some remarkable distances can be heard with patience.
These days there are far fewer English language broadcast stations on HF. Many are now internet only. Despite this, the challenge remains. My crystal set DXing website may give you some ideas.

Web SDR RXs
A reminder that there are lots of web SDR RXs on the air, so you can see what shape the bands are in in other places. If you have a high local noise level, these are also useful.

10m FT8 QRP (Sunday)
As usual, after a few minutes on 2.5W TX, I am RX only on 10m FT8. No QSOs. Nobody spotted me on TX and just MU0WLV (374km) on 10m FT8 RX. This latter could be aircraft reflection.
UPDATE 1345z: 6 stations spotted today so far. Very little Es evident.
