Rick's list is very good. I would also add LimeSDR as a good candidate (I
don't yet own one).
I have been using the RTL-SDR (original black one with the R820T chip),
RTL-SDR (Nooelec metal case with R820T2), RTL-SDR (blue with TCXO and
R820T2), Funcube Dongle Pro, Funcube Dongle Pro+ (FCD+) and SDRPlay RSP2.
The RTLs are "ok" for casual testing and signal hunting -- specially on the
bench. But their limited dynamic range, lack of band-pass filtering, high
noise figure and low ADC bit depth prevent using them in any serious
activity. I do however use the Nooelec for some 10 GHz experimentation
(with a LNBF). For monitoring satellites on VHF/UHF, I find the FCD+ the
best performer. The filtering, dynamic range and sensitivity is quite good.
The SDRPlay is also a very good performer, but it requires some careful
adjustments to perform as well as the FCD+.
73, Edson PY2SDR
