FunCube Frequency issue

Stations Receivers
1

I am attempting to change the FunCube frequency to 150.1 MHz but everytime I reboot the SensorGnome it resets to 166.376 MHZ frequency. The Funcubes are updated with the 20.03.48 firmware and originally set to 166.376 MHz, anyone may have an idea why it reset after changing the Frequency? Thank you!

Donald,

The sensorgnome software is what dictates the frequency that your Funcubes work at when plugged into the station. You could change the frequency within the deployment.txt file to 150.1 wherever you see it listed as 166.376.

That should work, but others here might have a better way to do this. Hope this helps!

Matt is correct. But notice that the frequency is often set 4Hz below the target frequency.

The same approach needs to be taken for listening at 150.1 MHz I believe. That is, to listen at 150.1 MHz, you would I think set the frequency in the deployment.txt file to 150.096.

Donald,

As Matt and Adam have said you need to edit replace the deployment.txt file to change all references to 166.376 to be 150.096.

The file is in the /boot/uboot directory on the SensorGnome.

There are a couple of ways you can do this:

  1. If you can ssh into the pi you can edit the file in place.
    Not for the faint of heart but I can walk you through this.

  2. You can make the changes using your laptop/ computer if you can mount the SD card using a suitable adaptor, and a text editor like Notepad.
    Do not use a word processor as that will corrupt the file.

  3. Replace the deployment.txt file with a version known to work with 150.1 Mhz tags.
    I can supply you with one that I use with project #307 receivers if you would like.
    While you are editing the deployment.txt file it would good, but not essential, to edit the first 4 lines that say:
    “info”: “default deployment”,
    “who”: “who is responsible for this deployment”,
    “contact”: “contact information for responsible party”,
    “shortLabel”: “changeMe”,
    to be something more meaningful.

Let me know if you want instructions for (1) or a working file for (3).

All the best
