*** NOTE ***   2024-02-12   It appears that NNPD is fully Encrypted now.  I have not heard any PD traffic on the stream for a couple of days.  Everything from the NNPD has said Encrypted.  I'll leave them in the feed for now, but will likely remove them at some point as they are no longer accessable.

 

My testing shows about 1 to 2 minutes delay from real time capture, until it is played back from Broadcastify.

2020-07-02  Increased volume by 50%.  Applied an audio gain of 1.5 in OP25.
2021-05-10  Added Alpha Tags in OP25 meta.json file.  They seem to be delayed about 1 to 4 seconds from the audio.  It appears that very short transmissions (less than 2 seconds) may not display the Alpha Tag.  EDIT:  Interesting, after my setup with Alpha Tags enabled ran for a couple of days, the Alpha Tags are now showing up on the client right at the same time as the audio, no more than a half second delayed now.
2021-09-30  Added a monthly reboot of the Raspberry Pi at 4am on the 1st of each month.
2022-03-14  Major update.  My rig is now running Raspberry Pi OS 11 (Bullseye) 64-bit Lite, OP25 (boatbod) from github, and Liquidsoap.  I completely rebuilt everything on another Pi 3B I had, then moved the mSD card into the main Pi running I have running OP25.  I'm hoping this configuration is more stable than using the audio aloop with darkice.  Time will tell.  So far it's working and sounds good.
2022-04-25  Updated to Liquidsoap 2.0.4 for better memory management.
