Every mode named here is a decoder in SDR-Receiver today.
LF time signals
DCF77 at 77.5 kHz, MSF and WWVB at 60 kHz, JJY at 40 and 60 kHz, TDF at 162 kHz
Needs coverage below 200 kHz
Use Airspy HF+ Discovery · Perseus · IC-R8600 · IC-7760 · Blog V3 with Direct Sampling
Not Blog V4 or NESDR. FUNcube Pro+ reaches TDF only.
HF modes
CW, RTTY, NAVTEX, DSC, FT8, FT4, WSPR, SSTV, HF Fax, ALE
Needs coverage from about 1.6 to 30 MHz
Use Blog V4 · Airspy HF+ Discovery · FUNcube Pro+ · Perseus · IC-R8600 · IC-7760 · HackRF, with 8-bit limits
Not NESDR, generic dongles, Airspy Mini or R2, Pluto. A Blog V3 in Direct Sampling reaches 20 m but no higher.
VHF and UHF narrowband
APRS, AIS, POCSAG, ACARS, RDS
Needs about 200 kHz somewhere between 88 and 470 MHz
Use any RTL-SDR · Airspy Mini and R2 · Airspy HF+ Discovery · FUNcube Pro+ · HackRF · IC-R8600
Not Perseus or IC-7760, which stop below 60 MHz, and not Pluto or PLUTO+, which start at 325 MHz.
ADS-B
Aircraft positions on the map, at 1090 MHz
Needs at least 2 MHz of bandwidth and 1090 MHz coverage
Use any RTL-SDR · Airspy Mini and R2 · HackRF · Pluto and PLUTO+ · IC-R8600
Not Airspy HF+ Discovery, which stops at 260 MHz, and not FUNcube Pro+, whose 192 kHz is far too narrow.
AIS on both channels
Channels A and B at once, around 162 MHz
Needs about 83 kHz around 162 MHz
Use every device that reaches 162 MHz at all — the bandwidth bar is low enough that no supported receiver fails it
Not Perseus, IC-7760 or Pluto, which do not reach 162 MHz.
Speech, RDS and general listening
Live transcribe and translate, FM radio text, everyday listening
Needs whatever band the station is on
Use any supported device
