Re: [HCDX] Mystery of two 40-metre interference cases closer to being solved

[Glenn Hauser <wghauser@xxxxxxxxx>]

SARL are presumably only concerned about 7205 because it is used for one hour a
week for the SARL broadcast via Meyerton 100 kW, Sun 0800-0900. None of the
online references show any other broadcast station in the world using 7205 at
this time (Sunday or any other day). Per DXLD 5-189, David Pringle-Wood in
Zimbabwe, jamming was going on against VOP but despite the fact that it had
already moved from 7120 to 11705, but the jamming was very broadband and VOP
operates only for one hour at 1700. In that case it ought to have been
interfering more with the hamband below 7100 than the broadcast band above
7200. Why aren`t SARL more forthcoming with what they are referring to?? Which
side of the border, with which country? (Glenn Hauser, DX LISTENING DIGEST)
