The AFEDRI SDRs are worth considering as well. Not quite the performance of my RF Space netSDR, but still respectable.

The AirSPY is okay, but skips band coverage and the SRPPlay DUO has a very poor receiver. The SDRPlay rspDX is better but the front end overloads.

> Hi Paul. I'd like to save you some grief. I've used the rtl-sdr v3. So I speak from experience. The Youloop was designed to be used with the Airspy HF+ which has very high sensitivity. The rtl-sdr v3 has quite poor sensitivity and using a youloop without an amplifier will leave you disappointed. Since you live in a big city on the 10th floor, just adding a broadband RF amplifier will most likely swamp the rtl-sdr v3 with FM and probably AM signals too. So plan on building or buying a lowpass and maybe a high pass filter as well. This is why I recommended the MLA-30. It contains the filters and an adjustable attenuator. Alternatively as mentioned you might want to spend your dollars on a better SDR that has good built-in bandpass filters like the Airspy or SDRplay.
