@ -133,7 +133,7 @@ Optimization on frequencies translation by rearranging compute steps implemented
Alalons (have I thanked you already?!) proposed a speed optimized arctan function. Performance gain is notable (factor ~2) but could reduce sensitivity slightly. I have seen that on receiving C1 mode datagrams - that's why the speed optimized version is not in use by default. A speed optimized arctan version can be activated by "-a" in the program options.
A new options "-o", which means "remove dc offset", was introduced. The overall sensitivity is better _without_ removing dc offset, so the user must start rtl_wmbus with this option:
