>=3B >=3B Propagation guru Alan= =2C G3NYK=2C always argues that there is no such

>=3B >=3B = true that in the summer we get more lightning static=2C the darkness

>=3B >=3B RF=2C but is it still possible to work DX at 136kHz at = mid-summer? This
>=3B >=3B was the idea behind an activity boost fro= m 15 to 22 June.
