472kHz band

In the autumn and winter, this is one of my favourite bands.

For several seasons now I have been on 472kHz WSPR transceive with my earth-electrode "antenna" in the ground. Despite the very low ERP (around 5mW!) it has been spotted well over 1000km away several times. My transverter which appeared in QST magazine about a year ago produces 10-15W, so with a decent antenna it could do well.

As far as I know, the USA is still awaiting access to this band. This is a fascinating band, well suited to WSPR.
