Since erecting my tiny 160m loft mounted vertical this last weekend I've used it on WSPR a few evenings with great success. The following tables show the unique reports received and sent on the band using (mostly) 5W. Most stations copying me can be copied here, despite the horrendous noise issues on the band at night.

160m WSPR reports given
So far, reports have been received from 9 countries with best DX being 1007km. Not bad with an antenna which is essentially a 1m long coil, a couple of top capacity wires and about 3m of feed wire from the loft to the upstairs shack and tuned against my central heating system copper pipes as a ground.
