good morning everyone, a similar problem happened to me with the high band qmx, after 10 hours of transmission and in wspr 10 mt, it went from 5W to 0w, the RF no longer comes out, I replaced the bs170 mosfets and nothing has changed , how can I access PUTTY to control the qmx, I don't know how to do it.? Thanks 73
