If you have downloaded the b31 demo5 binaries from the rtkexplorer.com website before today, please download them again. The b31 source code is fine but I had a build issue caused by a combination of not doing a build from scratch and changes to the project file that I ported in from the 2.4.3 code. I know this can cause RTKCONV to crash for an illegal memory access. I don’t know if it can cause any other issues.
Sorry about that!
Also, I just added an update to the end of my previous post with some further analysis. It doesn’t change the overall conclusion, but it does impact some of the details, so you might want to re-read the post while you are downloading the new code.
