17M band bug in the firmware
There is a bug in the ubitx_ui.cpp in line 246. It should read "17", instead it reads "18" in the code as shipped. This makes the button for 17 meters (18 Mhz) unusable, you have to use fast tune or direct frequency entry to get to 18 MHz. I have patched the source code on https://github.com/afarhan/ubitxv6
Remember, that the v6 source code compiles only when saved inside the sketches folder of the Arduino. This is an Arduino idiosyncracies.
