As yet, I have still to catch an Es opening on 6m WSPR. Others with higher ERPs have. I use WSPR as I can monitor activity remotely in the lounge on another PC, or even in the garden. WSPR also suits my disability as I do not have to use my voice.
In the last few summers 4X1RF (3519km) has received my 1W ERP WSPR on 6m several times. He is monitoring, so I just have to be patient and see if this path opens this year too. I know I'd have more 6m success on SSB, CW or JT65.
In the meantime, I am trying on both 6m and 10m WSPR although 10m WSPR is quiet here today.
