micro bitx kit from 2018 #ubitx

Look at your kit to see which version you have. It's most likely to be version 3 if you ordered it in 2018. Although there have been improvements in the newer revisions, the older ones are still quite usable and worth putting on the air. But you will likely need to make some changes. The one mod to the v3 board that is mandatory if you live in the US is the relay replacement. Your radio won't be compliant with?FCC regulations on some bands if you don't do it because the original relays don't have enough signal isolation. Regulations vary, so in some places that mod may be only recommended rather than mandatory. You could also make the radio compliant in other?ways, such as operating it with an external low pass filter designed for the band you are using, if you don't want to desolder and replace the relays. The other highly recommended mod is replacing some of the transistors with 2N2222 metal can transistors. That one will let you get full output on all bands, instead of having output power drop severely on the higher frequencies. There are other ways to do that, but the transistor replacement is the simplest one. There are many other mods as well, some very useful, some less so.
