The HackRF One seems to bottom out at 1 MHz, which is not ideal for SW listening. It's ceiling of 6.3 GHz is promising. It's transmit goes up to 6.3 GHz (I think.) If I could find a wide band 25W amplifier that went to 6.3 GHz that I could afford, things could get interesting. Those amplifiers tend to cost as much as a new car. It has so many noisy harmonics that the FCC would take an interest if I amplified it, and I'm not keen on building that many RF filters. I could probably control a HackRF One with a tablet, but I hate having a lot of sealed-box things in a larger box. I'd rather have components. I wonder if a Raspberry Pi or an Arduino Uno R4 would be better to run the HackRF. Someone's done it. I would like to have a small eInk display for the critical information (frequency, battery status, mode, etc.) and a larger LCD display to use when I'm actively seeking a signal. I don't get why HAM gear does not have an option to let you enter your radio operator call sign, and then look up the rest in a database to see what your privileges are. Let the database tell you who is active in your area and on what frequencies. Of course there should be a switch for totally-manual / emergency-communications mode.
