Well Jo, I did wonder when it failed , from your 1st note! Kostas was referring only to start up.
Does it only fail when you TX; in which case it could be RF that is causing the interface to fail ? If so, you may need to filter/screen your leads? Maybe ferrites or decoupling capacitors? The other thing I have seen is failure when the PC is idle for a long time; parts of your PC may go to sleep when not in use; if you think it could be this then you would need to check your power save options. This happened on my older XP PC. 73 Dave G3NKC -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Jo, YC0LOW Sent: 15 September 2010 16:13 To: REFLECTOR dx4win Subject: Re: [Dx4win] Error messages Hi Kostas and Dave, Many thanks for your responses. Dave, it happened only in the middle of the usage i.e: when the programme is running. Booting up process is always going fine. I never had problems whatsoever when using the software in my older laptop which its OS was Windows XP.
