Preparing the Red Pitaya's STEMlab 122.88-16 SDR
1 - Prepare the microSD card with Pavel Demin's Linux image
- Use Windows Disk Manager (
diskmgmt.msc) to delete all the partitions on the microSD card, then create a new partition and format it as FAT32 (FAT won't work).
- Download Pavel Demin's Alpine Linux image in zip format from https://github.com/pavel-demin/stemlab-sdr-notes/releases
- Unzip the above zip file and copy its content to the microSD card.
- Copy the
start.shfile from the zip file's folder "
apps\sdr_receiver_hpsdr" to the microSD card root directory.
- Insert the SD card in STEMlab SDR and connect the power.

If everything is ok, you will have the blue and green leds lit all the time and the yellow led blinking for a while until it gets an IP address from the DHCP server. At this point you must check on your router which IP address was assigned to the SDR and try to ping it and/or access it on your web browser.
Note: the SDR_Receiver_HPSDR start.sh script starts *two* (2) independent 8-slice SDRs, and the board will end up with two IP addresses and two MAC addresses on your LAN. So you can start two independent versions of Skimmer Server, each referencing a different MAC address by renaming the HermesIntf.dll as described. You can control which bands will get which antenna ports
2 - Running CW Skimmer Server
Install CW Skimmer Server.
Copy HermesIntf.dll to the CW Skimmer Server program directory (C:\Program Files (x86)\Afreet\SkimSrv).
XXXXare the last four digits of the MAC address of the STEMlab SDR (you can find the MAC address on the sticker on the RJ45 ethernet port).
Make a copy of the
SkimSrvdirectory and rename the copy to
HermestIntf_FFXX.dll, where XX are the last two digits of the MAC address
SkimSrv2.exe, configure frequencies and your call sign.
Start Reverse Beacon Network Aggregator.
