6m 10mW WSPR (Saturday)

Once again, I am on 6m with my 10mW WSPR. Although I have been copied locally, I have yet to get any Es spots. 

I am trying to simulate what would happen with ISM powers in the UK on 8m, which is open to all without a licence in the UK. I remain convinced this is enough power on WSPR to allow Es spots from Europe on 8m. 

With FT8, conditions would have to be exceptional to be copied I suspect.

UPDATE 1234z:  My experiment has worked. Quite a few European spots of my 10mW 6m WSPR. Some reports suggest even FT8 might have worked. Starting next week I shall try 6m QRPP FT8 at 10mW. It is my conclusion that 10mW ERP WSPR on 8m (available to all in the UK without a licence) would work under Es conditions.

UPDATE 1548z: I decided to try 6m FT8 at 10mW this afternoon i.e. earlier than planned. Already spotted by 14 stations across Europe (see map). Perhaps the shorter TX period of FT8 catches shorter openings than the 120 seconds of WSPR?
