First 10 minutes of use: Not bad for USD 100. Setup was ok, I chose to use HDSDR and when default setup was chosen, it was up and running. I needed to push LNA all the way up (which turned out to be UP towards zero!) for best sensitivity though.
Speaking of which: Not at the Perseus level, but not too far behind. Here's an audio file from KLAM Cordova Alaska 1450 with a relatively strong interfering signal on 1449. RSP1A is set up with USB, 2.7 kHz bandwidth. The Perseus is also set up with USB, but 3 kHz bandwidth. Antenna: 340 meters long beverage directed towards western North America. When I tested on KHKA Honolulu 1500 (below), the difference in sensitivity was noticeable with KHKA having audio and being partly readable on the Perseus. The RSP1A could only barely hear audio.
For sure not an SDR to replace the Perseus-grade SDRs. The price-performance ratio is good though.
More as it happens.
