Phil has already stated that there is some open source VNA software (which I had already found and downloaded <span style='font-family:Wingdings'>J</span> ) which should be a good starting point. It was going to take me some time to get my head around the PowerSDR software in it’s own right. Add to that the VNA software (written in Python by the way, not my native language) and I have a steep learning curve and will need time to get up to speed.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Are there any programmers note and or other documentation that I can use to help me get up to speed a bit more quickly?<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>--<o:p></o:p></p><p class=MsoNormal>Cheers<o:p></o:p></p><p class=MsoNormal>Luke<o:p></o:p></p><p class=MsoNormal>---<o:p></o:p></p><p class=MsoNormal>JP(Qual) : VK4KYT<o:p></o:p></p><p class=MsoNormal>----<o:p></o:p></p><p class=MsoNormal>Work thou not on energised equipment, for if thou doest,<o:p></o:p></p><p class=MsoNormal>thy fellow workers will surely buy beer for thy widow <o:p></o:p></p><p class=MsoNormal>and console her in other ways.<o:p></o:p></p><p class=MsoNormal>====<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
