¿ªÔÆÌåÓýGood source for LPF for RaspberryPi transmitter is ? ?Click on ¡°Place Order¡± and go down to item 12,? This design has the needed low insertion loss to keep the Pi power output usable. You need to buy a filter for each band you intend to use, but at $8 US can¡¯t complain too much. Very easy kit to complete. You will need to add connectors to Pi and antenna Tom kf7rsf |

Hello,
This email message is a notification to let you know that a file has been uploaded to the Files area of the Raspberry_Pi_4-Ham_RADIO group. File : /fox.zip Uploaded by : km4efp <km4efp@...> Description : Fox hunt hidden transmitter script using nbfm gpio4 and lpf/bpf OR pi's audio out and vox. Prompts for callsign and message and uses festival text to speech to convert to audio. This is a modified version of cputemp script by fotograf ale.

Thanks when i get time i will make it so you can save permanent settings to be more easily deployed in the field along with menus to perhaps set frequency or other options and display default values for less technical people. Maybe implement cw options and menu for switching between vox with handheld radio and pi with nbfm running.
Or someone else can take it and do the same.
Thank you guys for giving me a proper starting point for an open source fox hunt transmitter.

Would it not have been better to start a new thread
instead of hijacking a system admin notice!!
Then this useful info could be found by others,
instead of being submerged and not responding to relevant searches of the
archive.

Very nice. Let me get a list of settings that work best for you to default into my script. Why did you change deviation to 4 from 5
Please check out the latest Pifox.zip Description : V1.06. Unzip files then chmod +x all files then run "sudo ./pifox.sh" easy to navigate menus set the rest of the script. Lots of new features including a mode to run a pre-configured fox hunt transmitter requiring no additional user input when your pi is powered on. Excellent for deploying a fox box in the field.

Very interesting, well done!
I took a look at the code but I've not yet been able to run it. Please check the sampling rate set in the code for the packet radio audio stream. It sounds to me to be there a disalignment between the generated audio file (22.5kHz) and the nbfm transmission (44.1kHz). 73s de Ale, fotografAle, IK1PLD |

Nevermind here is newest stable release for you to test. Conversations arent approved fast enough for my development
File : /pifox.zip Uploaded by : km4efp <km4efp@...> Description : V113. This is the latest stable release. First unzip all files then chmod +x all files. Run "sudo ./pifox.sh" edit configuration and then run. Readme coming soon. For now edit settings walks you through setup. You can access this file at the URL: |
