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!). Let’s suppose you found via
lsblkyour SD card is at
umount /dev/mmcblk0 mkdosfs -F 32 -n HPSDR6rx /dev/mmcblk0
download the latest .img.zip Red Pitaya beta Ubuntu img 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 (login/password root/root) using Avahi
or via serial port
- Via the web browser Red Pitaya control panel, install Pavel’s six receiver HPSDR app.
# Start the SDR Receiver compatible with HPSDR at boot time cat /opt/redpitaya/www/apps/sdr_receiver_hpsdr/sdr_receiver_hpsdr.bit >/dev/xdevcfg . /opt/redpitaya/www/apps/sdr_receiver_hpsdr/start.sh
rebootthe Red Pitaya
Check that Red Pitaya HPSDR server is running
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
Setup laptop with GNU Radio HPSDR
There are several HPSDR compatible programs on Linux, Mac, Windows.
GNU Radio Companion HPSDR client
apt install gnuradio gr-hpsdr
Note, at the time of this writing, the Ubuntu repository
gr-hpsdr is out of date, only supporting 2 Red Pitaya Hermes receivers.
Be sure the default
gr-hpsdr works for you, and then consider the current Github:
git clone https://github.com/Tom-McDermott/gr-hpsdr
for the Cmake command, you may need to tell which directory
gnuradio-runtime.pc is in to avoid
GnuRadio Runtime required to compile hpsdr
PKG_CONFIG_PATH=/usr/lib/x86_64-linux-gnu/pkgconfig cmake ..
Prereqs you’ll need include
libboost-all-dev libgsl-dev libczmq-dev
You can make a block diagram with GNU Radio Companion, using the
If it doesn’t work for you, do
note that the version 1.2 of
gr-hpsdr didn’t seem to update the connection between Gnu Radio Companion and the modules yet.
So I use the
top_block.py directly in Python e.g.
It seems that GNU Radio 3.7.10 is needed as 3.7.9 just hangs waiting for connection. You can use Ubuntu ≥ 17.04 (which has GR 3.7.10 already), or 16.04 (comes with GR 3.7.9 that doesn’t work) if you manually compile GNU Radio 3.7.10. Or Debian/Raspbian Stretch 9 works too.
If you do build your own GNU Radio, be sure to remove the system-installed
gnuradio first, or you will have to recompile and that takes a while.
apt remove gnuradio
