@raymaccarthy @vfrmedia @FediThing the cheap DSP ones have been hacked by the manufacturers to receive SSB too, FWIW

@bhtooefr @FediThing @vfrmedia Yes, but the super cheap DSP chips are rubbish compared to a 1960s Hong Kong superhet. I've tried them. I had a Tesco Worldband LW/MW/FM & multiple SW and it wasn't bad. I bought another for a friend which was terrible. The superhet insides replaced by the cheap ASIC DSP chip and tuning cap by a polymer variable resistor. Same model ID! The problem may be lack of dynamic range in the internal ADC. Also many haven't enough SW band. You need at least 4MHz to 23MHz.
