CWX and PowerSDR crash when sending several macros in a row. See https://www.youtube.com/embed/ZUUKIJ2qi10?vq=hd1080 for an example, crash happens around 25 seconds in. PowerSDR has to be rebooted when this happens. It has happened on a Flex 1500 and Flex 3000 with different PC, different versions of PowerSDR, different versions of Windows . It happens when transmitting with zero drive, so not RF related. It is fine if I leave several seconds between each macro .
