More and more countries are being allocated the narrow WRC15 60m allocation. Many suffer from man-made interference on the lower bands from SMPSUs and similar. Nonetheless, this is an important new band that will be increasingly important as the sun gets quieter.
I have tried WSPR on this band in the past and must try again soon, although I have no suitable antennas, so use a random wire and my ATU.
In the UK we have not been granted access to the WRC15 allocation yet, so it important to stick to the bits we do have access to.
