Introducing UV-K5 Version 0.3Q (Stable version, added FT8 QSO) Version 0.3Q is mostly the same as version 0.3C. If you are already using 0.3C and do not plan to run FT8, no update is required. Since 0.3C was tested by several beta testers and there were no major problems, we only changed the name to the stable version 0.3Q.
