AirSpy Mini VS Funcube Dongle
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 +

How can I get rid of this DC spike in the Funcube Dongle ?

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.

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

Most SDR programs have an option to eliminiate the DC spike. I've been using Gqrx and can't specifically remember how to do it in others, but in Gqrx it's right on the receiver options tab.
