Updating strong satellite receiver software
For doing diagnostic and low signal level work Linrad is full featured and fast.
osmocom_fft comes with GNU Radio module gr-osmosdr and is the natural and best way to use gr-fosphor; a GPU accelerated display.

Connect your USB drive or SD Card via USB cable to the decoder 2. Wait for 15 seconds then go to software update section on your receiver 5.
That can be resampled inside the RTL2832U to present whatever sample rate is desired to the host PC. The actual output is interleaved; so one byte I, then one byte Q with no header or metadata (timestamps).
This resampled output can be up to 3.2 MS/s but 2.56 MS/s is the max recommended to avoid losing samples. The samples themselves are unsigned and you subtract 127 from them to get their actual value.
multimode has a very full and configurable GUI (it works great with GPU accelerated displays like gr-fosphor).
The quadrature mixer produces a complex-baseband output where the signal spans from -bandwidth/2 to bandwidth/2 and bandwidth is the analog bandwidth of the mixer output stages.
Note: To safely upgrade your receiver, Do not Power Off during installation, You must have a stable electricity or power generator.
A sudden power outage can cause damage to your decoder.
The Sigma-Delta ADC samples at some high rate but low precision.
From this a 28.8 Msps stream at 8 bits is produced.
