Around last Year i’ve developed a DVB-S Receiver in Software to learn more about Signal Processing and Multithreading/SIMD Optimization. This software is supposed to be the starting point for experimenting and implementing my own DVB-S receiver on a FPGA Board. It has mainly been written for personal use, so it’s not very user-friendly

Maybe this is also interesting for you, because there are many people here with SDR Boards.

I hope that you can give some Feedback and constructive criticism.

This Software does only run on quite modern CPUs with SIMD instruction sets and AVX support. Should be Intel Haswell and above.

There are a few Screenshots attached as a reference how things should look like ^^

MPEG-TS output is localhost, UDP at port 8888.

Tested with RTL-SDR and hackrf. LimeSDR is not tested, maybe it works, maybe not.

DVB-S2 is being experimented with, but there is only DVB-S1 support for now.

Current Version: 2.0.9

Quick Guide:

• Center the DVB-S transponder, so that it’s in the middle of the FFT plot.
• Change the symbolrate slider so that it’s near the actual symbol rate. Using the ‘Show FFT after Matched Filtering’ checkbox helps.
• Play with the Timing Recovery Loop Gain and Damping Sliders until you can see a circle inside the IQ plot and set appropriate Baseband-Gain Settings without overdriving.
• Enable Carrier recovery (coarse, fine is not usable right now) and play with the loop gain/damping. Higher gain for locking, until you can see a derotated QPSK constellation.

lower gain afterwards with reduced damping works best.

• rotate the constellation, and skip symbols, until you can see the sync counter going up. Don’t forget to choose the right FEC Rate before.

Step 1 – Configure your BrandMeister Hotspot Password:

Click your callsign at the top right

Click “SelfCare”

Turn on “Hotspot Security” and define a password

Click “save”

Step 2 – Configure Pi-Star with your Hotspot Security Password:

Head to the configuration page on Pi-Star, assuming your hotspot is accessible by http://pi-star.local the below link should take you straight there…

In the DMR section, you will now find the HotSpot Security field, if you are using DMRGateway this will be shown as “BM Hotspot Security” as in the image below:

Set your password (the same one you used in the BrandMeister Selfcare page) and press apply…

You are all set, using Hotspot Security, please note that if this field is empty, you will revert to using the default password from the DMR Host file provided with Pi-Star updates.
