Hello, I own a Prangins RC clock but this Swiss DCF pransmitter is no longer on-air. Could I use your equipment to make a simulated Prangis transmitter? I understand that the Prangins coding is 99% the same as the DCF77 coding, but the carriier is 75khz in stead of 77.5 Thanks for your help Jan

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
