I'm having the same issue with a setup on a 2nd computer. It works fine on my desktop but when I set it up on a laptop, the sdrsharptrunking.log doesn't get created. I installed UniTrunker to %APPDATA%\UniTrunker so writing to the folder shouldn't be an issue. When I call is received, I see the control receiver switched from "Parked" to the frequency without an issue. I also copied the remote.dll file to the UniTrunker folder.
Edit - I forgot to install VS C++ runtime (http://www.microsoft.com/en-us/downl...s.aspx?id=5555
). It's working fine now!
