Mark’s Global Spectrum Project MK2

Many thanks to SWLing Post contributor, Mark Fahey, who shares the following:

It’s been a fun weekend getting the first two remote modules for the Spectrum Project MK2 together. These modules tune into and then digitally preserve broadcasted human communication; music, discussion, culture for future generations to study and ponder.

This initial version of the hardware provides 0-30MHz with four (simultaneous) independently configured receivers that are controlled remotely from anywhere on the planet. The first of the modules will be installed near Vladivostok in Russia’s far east and the second is planned to go to one of the “stans” in Central Asia, most likely Kazakhstan.

The hardware includes a KiwiSDR 0-30MHz SDR 4 channel receiver AM LSB USB CW FM plus GPS for precision timing and location information. A BeagleBone Green is the CPU and the compact 100KHz-30MHz active antennas we are using are precision built by RA0SMS in Irkutsk, Siberia, Russia.

(Note to fellow SDR geeks – the WinRadio Excalibur running on the iMac [above] is not part of the remote system – it just happens to live on my assembly bench).

Remote Module #1 prior to sealing.

This first generation is built to connect to a wired internet connection and power supply. The hardware includes a KiwiSDR 0-30MHz SDR 4 channel receiver AM LSB USB CW FM plus GPS for precision timing and location information. A BeagleBone Green is the CPU and the compact 100KHz-30MHz active antennas we are using are precision built by RA0SMS in Irkutsk, Siberia.

Remote Module #3 and later will support solar power and a 4G/ LTE connection so the devices can be located anywhere on the planet that has reasonable cell phone coverage.

Remote Module #2

Remote Module #2

This is Remote Module #2 sealed and ready for connection to a network and power supply. The hardware includes a KiwiSDR 0-30MHz SDR 4 channel receiver AM LSB USB CW FM plus GPS for precision timing and location information. A BeagleBone Green is the CPU and the compact 100KHz-30MHz active antennas we are using are precision built by RA0SMS in Irkutsk, Siberia.

Remote Module #3 and later will support solar power and a 4G/ LTE connection so the devices can be located anywhere on the planet that has reasonable cell phone coverage.

Don’t forget you can tune into the prototype system now up and running near Sydney Australia. Point your browser to http://mediaexplorer.ddns.net:8073

This is simply amazing, Mark. I can’t wait to try out the receivers in your Spectrum Project MK2 once they’ve been deployed and implemented. We’ve talked about this concept before, but what I love about Mark is he simply pulls the trigger and makes it happen as soon as technology has made it possible to implement.

Mark: please keep us posted with your updates!

Spread the radio love
