I do use a loop antenna, which presents a pretty constant impedance regardless of the weather. I have many valve radios including high power amplifiers, transmitters and receivers (mostly on hf). I enjoy the warm glow of a valve set, but I also appreciate the efficiency of FETs particularly when running in continuous beacon mode. Vy 73 Warren K2ORS/WD2XGJ (Member of the Eddystone User Group)
