This is the first tests I've made with my uBitx on the 14th and 15th of september 2019.
It's very cool because you can set up a WSPR directly in the KD8CEC firmware with your callsign and grid square in the EEPROM of the main board of the uBitx.
So, with this configuration, you just need to plug your uBitx to an antenna and push PTT button to launch a 2 minutes WSPR beacon cycle.
As it's WSPR, you need to be well synchronized when you push the PTT button. In fact, you have maximum 2 seconds after an even number of minute to push it (for example 22h30, 22h32, 22h34, etc). If you push it at anytime, the other stations won't be able to decode you.
