Setup Red Pitaya for six HPSDR receivers
Setup Red Pitaya HPSDR receiver image: format a micro SD card to FAT32.
Find the SD card device name from
df – be sure you don’t overwrite your hard drive!
Suppose the SD card is at
umount /dev/mmcblk0 mkdosfs -F 32 -n HPSDR6rx /dev/mmcblk0
Download the latest .img.zip Red Pitaya beta Ubuntu image and then extract to the SD card:
mount /dev/mmcblk0 /mnt/HPSDR6rx unzip -p redpitaya_ubuntu*.img.zip | sudo dd of=/dev/mmcblk0 bs=4M sync
Boot the Red Pitaya with this SD card. Connect to Red Pitaya via Ethernet using SSH using Avahi.
or via serial port
Via the web browser Red Pitaya control panel, install Pavel’s six receiver HPSDR app.
Red Pitaya add the following to
rc.local to auto-start the HPSDR server
# Start the SDR Receiver compatible with HPSDR at boot time cat /opt/redpitaya/www/apps/sdr_receiver_hpsdr/sdr_receiver_hpsdr.bit >/dev/xdevcfg source /opt/redpitaya/www/apps/sdr_receiver_hpsdr/start.sh
reboot the Red Pitaya
Check HPSDR server
On the Red Pitaya (or via serial/SSH)
ps aux | grep hpsdr
You should see
/opt/redpitaya/www/apps/sdr_receiver_hpsdr/sdr-receiver-hpsdr 1 1 1 1 1 1
Where all the 1’s mean that each receiver is using
RX1 SMA connector.
You can configure each of the receivers to use

apt install gnuradio gr-hpsdr
