I’m gettting a 241 mhz peek with the DevTerm … I don’t get it when I run the SDR on my old Panasonic Tough Book I7… maybe it’s the aluminum case… Also there is a forum for an Operational Frame (Field OP’s Shell) for the devTerm that includes an SDR mount on the left side … I use a short USB jumper and it holds everything neat and tidy…
