Now is also 40 and 20 meter available, HF is complete. Also 60 meter, but this band is not allowed in the Netherlands. Opera is good for checking band conditions or testing the antennas.
Can I say conditions were poor today when I was spotted in Australia with 5 watt? With Opera no DX really on 30 m. Maybe not enough users on the frequency. With WSPR I was spotted in VK. It seems that when conditions are poor, Opera fails. With good conditions Opera is a slightly better in performance than WSPR.
