Hi Lars I think the problem is that the OCX file C:\Windows\SysWOW64\MSCOMM32.OCX is not registered to the operating system. So, could you please carry out the following procedure. 1)  Start up CMD.EXE with Run As ADMINISTRATOR 2)  At the command prompt do CD C:\Windows\SysWOW64 3)  At the command prompt do regsvr32.exe MSCOMM32.OCX 4)  A window should pop up saying " .... Succeeded" I've attached Build 277 which focuses in on the clsElektorSDRShield.GetVer() function call which was the last thing reported in the log file. So could you unzip and copy the new executable into C:\Program Files (x86)\G8JCF\G8JCFSDR folowing the instructions you used for Build 276, eg rename G8JCFSDR_277.EXE to G8JCFSDR.EXE etc. Now start up Build 277 using the "G8JCFSDR Trace" Start Menu entry and repeat what you did for Build 276 If the registration was the problem then the G8JCFSDR should work correctly. If the registration was NOT the problem, then we should get details in the log file of precisely where the error happened, and if so could U please send me the log file. Thank you - we must be getting close !! 73 Peter - GM8JCF

Hi Lars I have attached G8JCFSDR_275.ZIP to this posting. The G8JCFSDR Build 276 has been updated with extensive instrumentation/logging in areas concerned with the Elektor SDR Shield. To use Build 276, please proceed as follows. 1)  Rename the existing G8JCFSDR.EXE to something else, eg G8JCFSDR_274.EXE. The G8JCFSDR.EXE is located in C:\Program Files (x86)\G8JCF\G8JCFSDR 2)  Download and unzip the attached G8JCFSDR_276.ZIP into C:\Program Files (x86)\G8JCF\G8JCFSDR. 3)  Rename C:\Program Files (x86)\G8JCF\G8JCFSDR\G8JCFSDR_276.EXE to C:\Program Files (x86)\G8JCF\G8JCFSDR\G8JCFSDR.EXE 4)  Make sure there is a directory named C:\Temp present 5)  From the start menu, click on "G8JCF | G8JCFSDR | G8JCFSDR Trace" which will start the G8JCFSDR in logging mode. The G8JCFSDR logging window will be displayed. 6)  Now go into Config, and run through the procedure required to configure the G8JCFSDR for the Elektor SDR Shield. 7)  At some point the 438 runtime error will be thrown up and the G8JCFSDR will crash out. 8)  Now from the start menu, click on "G8JCF | G8JCFSDR | G8jcfsdr Logfile" which will load the log file produced from the last run into Notepad so that you can have a look at what went on. 9)  The G8JCFSDR logfile is located at "C:\Temp\G8JCFSDR.log". Please email me that log file so that I can see where the G8JCFSDR failed. Hopefully with that information I can determine what the problem is and provide a fix. Thank you for your patience. 73 Peter - GM8JCF
