Sadly, I am in a position to comment on this. I have been meticulous in unplugging my HackRF One (& Blue) but at the weekend I forgot and keyed up my HF transmitted for a second with about 50W of RF at 18MHz. That blew the RF amp in the HackRF One.
The HackRF was next to the transmitter and the antennas plugged into each are quite close. I am interested to know when it is possible to blow the amp, for example is it possible: - when the HackRF is unplugged from power; - when it is connected to an antenna but not powered up; - when conected to an antenna and powered up but the RF amp switched off? How paranoid do I need to be regarding unplugging?! Simon.
