Possibly if it's a very short feed to the efhw that could be the issue. The ubitx can be more sensitive than many rigs. So try various things, including earth connection if it can be short compared to a quarter wave length. I concur RF is escaping antenna or feedline, and getting back onto something attached to the raduino.?
