8m experiment - last day at 10mW ERP (Wednesday)

Today is the last day of my 10mW ERP 8m WSPR tests locally. The TX is due to be turned on again at 0900z. 6 locals have copied me with 10mW ERP even with non resonant antennas. 

My reading of the UK ISM rules suggests that anyone may operate 10mW ERP beacons without a licence, with callsigns not legally needed (or make one up) as long as the technical requirements and IR2030 are both met. For beacons, that do not result in a product going on the market, self declaration is fine. If you are in any doubt, seek your own legal advice. I honestly think OFCOM cannot really be bothered as we make them no money!

UPDATE 0931z: Been on 10mW ERP TX since 0858z (40% TX). No spots.

UPDATE 1437z:  Steve G4WSZ (11km) has only spotted me twice today. He had to move his 6m dipole as his fence was being replaced. It looks like with his 6m dipole at only 1m over the ground, it is very marginal.

UPDATE 1445z:  There has been speculation on the 8m io group just why the FCC and OFCOM seem so dead against allocating even the tiniest amateur band at 8m with heavy restrictions. The answer in many countries may well be the military have the last word and want to keep people off. This is pure speculation, but it would make sense. Secrecy rules probably saying so right out!
