10mW?

 As a keen QRP FT8 operator on 10m, 8m and 6m this thought occurred to me.

If you are copied with a plus value S/N (say at 1W, or even 5W) there is a very good chance you would still be copied at 10mW. Of course, this will depend on the noise floor at the RX and finding a clear frequency.

Many have been surprised that licence free 8m 10mW ERP FT8 has been copied right across Europe. It does not surprise me at all. 

What does surprise me is how few have tried this especially in the Es season. Just think, no licence, make up a callsign that WSJT-X and PSKreporter can work with and have fun. 

Remember operating under ISM rules is not amateur radio.
