I finally broke down and used cvs with SuSE linux and upgraded to DX Spider Cluster version 1.51 (build 58.3) on Linux Copyright (c) 1998-2004 Dirk Koopman G1TLH Tried filtering acc/spot by_dxcc w and acc/spots freq 20m,15m,10m 1431Z Let it run for awhile. The filter works, but sh/mydx doesn't give me anything. Any ideas? 73 Hank K8DD
