Writing for many different program schedules is probably not necessary. There are numerous sources of scheduling information. Check your local packetclusters, packet networks, telephone BBS nodes, and interactive computer networks. Local newsstands may carry copies of SWL magazines and comprehensive books such as the ÒWorld Radio TV HandbookÓ or ÒPassport to World Band RadioÓ. Or simply listen on the broadcast bands and you may find SWL programs that announce current frequencies and languages being used by different broadcasters.
