Greetings all,
I am restoring quite a few RCA Radiola radios from the 1920s and will be using
Rivendell to run an automated AM Radio Station. The purpose is to transmit to
the restored Radiola sets throughout my bed and breakfast inn for the enjoyment
of my guests.
The purpose of this message is to seek advice, discussion or instruction
relating to two related goals for my Rivendell-run AM radio stations:
1. detecting network-feed audio tones that signal local-break-start and
rejoin-network
2. integration of EAS/SAME alerts to my station without expensive external
hardware
I already reviewed the Rivendell wiki article on tone detection . As the author
acknowledges, it seems there is an opportunity to achieve this goal without
using WINE to run a Windows program. Please note that I *only* use Linux,
mostly CentOS 7, for servers and for workstations.
I found two projects in my research which seem to be applicable:
* multimon-ng : decoding digital transmission modes, including EAS
* dsame : EAS/SAME alert message decoding via Python
For the WX radio reception of EAS/SAME signals, I plan to use a RTL-SDR USB
dongle.
NOTE: I have a bit more latitude in EAS solutions since I will be running FCC
Part 15 AM transmitters.
OK, that said...
Assuming I can get the above combination of open source software and RTL-SDR
dongle working as expected, I then need to figure out:
1. What does my bash script need to do in order to interrupt the live
broadcast in Rivendell to play the text-to-speech version of the EAS/SAME alert
received?
2. Can I use the multimon-ng software to listen for the network-feed
signals, and if so, what does the bash script need to do to interface with
Rivendell correctly to trigger the right actions?
I have tried to balance providing enough detail with being succinct enough not
to cause any spontaneous comas. :-)
Does anyone have anything to add, any experience you are willing to share, or
any feedback on this project of mine?
Thanks,
Eriks
PS: I intend to fully document the HOWTO of all this on the Rivendell wiki once
I figure it out and have perfected it.
