      Current state of vpsBoard   02/04/2017

      Dear vpsBoard members and guests:

      Over the last year or two vpsBoard activity and traffic has dwindled. I have had a change of career and interests, and as such am no longer an active member of the web hosting industry.

      Due to time constraints and new interests I no longer wish to continue to maintain vpsBoard. The web site will remain only as an archive to preserve and showcase some of the great material, guides, and industry news that has been generated by members, some of which I remain in contact to this very day and now regard as personal friends.

      I want to thank all of our members who helped make vpsBoard the fastest growing industry forum. In it's prime it was an active and ripe source of activity, news, guides and just general off-topic banter and fun.

      I wish all members and guests the very best, whether it be with your business or your personal projects.

      -MannDude

Remote recording of FM radio

6 posts in this topic

Working on a solution where I have a RasPi in a remote location to record FM radio (certain times, certain length of time) using an rtl2832u stick. This would then be sent (or fetched) via a network connection to a central location.

Anyone have any suggestions and/or ideas on what software they'd use in a similar situation?

I'm eyeing up the ftl_fm stuff and perhaps VLC too.. but open to suggestions :)

arecord probably with a cronjob that files, runs for duration then dies where another one then fires off with a new time + data stamped file...

ffmpeg is capable also.

You could do the whole Shoutcast or similar Icecast on the Pi and on your remote end have an audio catcher like streamripper running and cutting the audio down to files for archiving.   Depends on your intended use though.

Have used everything except rtl_fm in the past to hack things together.

Interested in hearing what you cobble and what makes run when done.  Interesting project :)

Shoutcast wouldn't work really. 

 

I've gone for rtl_fm, Sox and avconv to record radio at a specific time, for a specific length, convert and send 'home'. Wrote a handful of scripts to control it all and its working well. 

 

Just to note, when I said remote location, I didn't just mean 'not here, not local' I meant in the middle of nowhere :) 

Now experimenting with a pvr solution for the same though I think my cli version is better. 

 

Will have to go and install these too eventually in to the wilderness!

Also, the raspi 3 is a brilliant piece of kit!
