DX Central: Under Review | Which SDR is BEST for AM DX? (Part I)
It is not an easy question to answer, but in this video, we try to begin peeling back the layers of the question "which SDR is best for AM DX?" In this first part of a multi-video series, we examine the three most popular SDRs for AM DX: Perseus, Airspy's HF+ Discovery and SDRPlay's RSPdx. Using a single antenna and the SDR Console software to test all three, we pull in nighttime DX signals covering various situations such as crowded channels, adjacent local stations, graveyard channels and weak signals. Does one of these SDRs stand above the rest in performance? Or, are they all equal? You can be the judge with out in-depth testing.

To jump ahead directly to specific testing scenarios, use the timestamps, below:
TEST SCENARIO 1: Crowded Frequency - 550 kHz
10:21 | Perseus
10:48 | HF+D
11:15 | RSPdx
11:45 | Perseus
12:13 | HF+D
12:39 - RSPdx

TEST SCENARIO 2 - Clear channel with adjacent local station 10 kHz above- 720 kHz
16:07 | HF+D (USB)
16:35 | RSPdx (USB)
17:13 | Perseus (USB)
17:43 | HF+D (USB)
18:05 | RSPdx (USB)
18:29 | Perseus (USB)
19:00 | HF+D (LSB)
19:30 | RSPdx (LSB)
19:51 | Perseus (LSB)

TEST SCENARIO 3 - Strong clear channel with strong adjacent stations above and below - 760 kHz
22:07 | RSPdx (LSB)
22:33 | Perseus (LSB)
23:05 | HF+D (LSB)
23:35 | RSPdx (USB)
24:05 | Perseus (USB)
24:42 | HF+D (USB)

TEST SCENARIO 4 - Graveyard channel with strong, local music station 10 kHz below - 1400 kHz
28:05 | Perseus (LSB)
28:40 | HF+D (LSB)
29:04 | RSPdx (LSB)
29:37 | Perseus (USB)
30:12 | HF+D (USB)
30:44 | RSPdx (USB)

TEST SCENARIO 5 - Weak signal on empty frequency - 1640 kHz
32:36 | HF+D
32:57 | RSPdx
33:25 | Perseus
33:51 | HF+D
34:26 | RSPdx
34:50 | Perseus
