It's not clear yet, but I wanted to get a single portable device that allows for reception of all the most important frequencies, which I think includes shortwave, HF, VHF, NOAA weather and the amateur radio bands.
Is there a device that does all of this?
The "big three". Some of the more modern bits of kit cover "DC to Daylight" frequencies.
