The fun cube dongle wins hands down on dynamic range and sensitivity what it lacks in bandwidth
I just wish it would work like my airspy mini

AMSAT Community,
I have the same problem and would really appreciate any information on a fix. I have read about the origin of the DC Offset problem but I don't see any way to correct the problem.
I'm a happy owner of three (3) Funcube Dongles. One of the best values in SDR equipment.

Signal Comparison of AirSpy Mini vs Funcube Dongle PRO+
432.440 MHz
AirSpy Mini SDR 3/6 MHz
IF = 9
Mixer = Max 15
LNA = Max 15
Noise Floor -80 db
Signal Peak -50 db
S/N = 30dB
Funcube Dongle Pro + 192 KHz
LNA = Yes
Mixer = Yes
IF Gain = 11
Noise Floor -80 dB
Signal Peak = -35 dB
S/N = 45 db
RTL-SDR Dongle 2 MHz
Did not compare at all - Noise Floor -50 dB / Bad S/N
HackRF
Did not compare - was more a GNUradio Tool
The Funcube Dongle was 15 dB better than the AirSpy Mini
But remember Fincude SBR is 192 kHz and AirSpy Mini is 3 or 6 MHz
Best: Funcube Dongle Pro +
