[GCARC] More stuff to do with a Raspberry Pi

[Jon Pearce]

For those planning to attend Tech Saturday and build a Hamclock on a Raspberry Pi (or just watch one being built) here's some additional info on all sorts of stuff to do with a Raspberry Pi.

Hamclock Documentation: https://www.clearskyinstitute.com/ham/HamClock/HamClockKey.pdf
How to change the hamclock display options: https://dl1gkk.com/ham-clock-raspberry-pi/

Some other programs:
How to install CHIRP HT programming software: https://kd9cpb.com/chirp (somewhat detailed - there are better directions elsewhere)
Ham-Pi collection that installs many programs (I haven't worked with this successfully): https://mawcg.org/ham-pi/
Installing FL-Digi on the Pi: https://km4nmp.com/2020/01/11/installing-fldigi-on-the-raspberry-pi/
Installing the Gpredict satellite visualization and control program: https://forums.raspberrypi.com/viewtopic.php?t=271488
Installing the Direwolf APRS program (very detailed but very powerful) https://github.com/wb2osz/direwolf
Other programs: https://w6aer.com/getting-started-with-raspberry-pi-applications-and-projects-for-ham-radio-operators/
A huge list of ham-related programs: https://www.raspberryconnect.com/raspbian-packages/39-raspbian-hamradio
Even more programs: https://hamprojects.wordpress.com/2020/09/06/raspberry-pi-for-ham-radio/
One guy's ultimate hamshack Pi installation with some fancy hacks to the Pi: https://www.kb6nu.com/km4ack-on-building-the-ultimate-raspberry-pi-for-your-shack/
Even more programs for the Pi. Check these out - there's some cool stuff here, and it includes a lot of stuff listed above: https://wiki.oarc.uk/pi_software

If you install the most recent version of Raspian the VNC program won't work.  To avoid that:

  1.  Install the Legacy version, or
  2.  If you've already installed the current version run this command:  sudo systemctl restart vncserver-x11-serviced

A fix for the RTL_SDR device running on a Pi: https://www.rtl-sdr.com/tag/raspberry-pi/

Building a transmitter from the Pi by modulating one of the GPIO pins: https://www.rtl-sdr.com/building-a-ham-tranceiver-with-an-rtl-sdr-raspberry-pi-and-rpitx/  Might want to check the quality of the signal...

Setting up a SpyServer remote SDR radio: https://www.rtl-sdr.com/rtl-sdr-tutorial-setting-up-and-using-the-spyserver-remote-streaming-server-with-an-rtl-sdr/   also this: https://www.rtl-sdr.com/spyserver-2-0-released-efficient-streaming-airspy-rtl-sdr/

Building a 433 mhz decoder to spy on local IOT devices with an RTL-SDR: https://www.apalrd.net/posts/2021/rtl433/

Finally - for those who have an SDR Play radio there's now a Pi version of their new SDR Connect software including the server version! It runs on the 64-bit version of the OS and wants a Pi 4 but would be really cool for a remote system or a local dedicated SDR radio. I haven't tested it yet but will check it out over the next few weeks.

See you tomorrow!
