When I use the DDE tracker plug-in from Ian Gilmour (MM6DOS) as described also here: http://www.pe0sat.vgnet.nl/tag/sdrsharp/ I do indeed see in SDR Sharp the DDE Client.

I also can see when I connect it the realtime output of SATPC32 correctly displayed (sat name, freq, ..).

However, when I hit PLAY to start the FCD to become active, the DDE information freezes (no updates anymore) and the FCD also does not go to the freq from the DDE.

Who can tell me what I do wrong ?
