There is something that comes pretty close to your list.
You can download it from www.funkstation.info
go to software and don't forget the country.txt file.
It's written for windows systems but without *.dll's, registry inputs etc.
It is a contest/logging software originally made for HF but can handle GRID fields, can be networked with proper handling. The slaves will synchronize log datas after reconnecting, it handles packet, Telnet DX-cluster, controls TRCVR's. Can run trcvr-control and CW/PTT line over 1 COM-port, has greyline maps (rectangular or great circle), some statistics (GRID, IOTA, DXCC), an excellent tool for printing cards or labels etc. etc.
The only problem for you may be the German written helpfile... and that UHF/VHF contests are not implemented yet. The English help file we are working on and Ben (DL7UCX@qsl.net
) is mostly very fast while implementing new wishes.
