Can you image what RPI + P175 can do together
« on: March 01, 2016, 02:57:32 pm »
Hi all,
I'm working on a funny project right now, made of a RPI 2 and a P175...
Here the URL:
http://fmbox.ddns.net/home
Done with a RPI 2 with an USB stick for Mysql and audios files
    -RS232 card on the RPI 2 to communicate with the P175
    -A P175 with an LCD (could be without)
    -5V alim for the RPI that suplies power also for the P175
    -everything  in a lovely 19" enclosure  8)
Waiting for your remarks  :-\

Hello,
Yes it is an interesting project. Have You noticed that the many alarms on the Rennes receiver probably is because the reception overall is bad there (low levels on almost all frequencies). Stations with high levels do not get many alarms for too high excursion (deviation). My experience is that one cannot measure deviation properly if the level is under 50 dBµV. Is there any way to improve the reception in Rennes? Better/higher antenna?

Hi,
You are right, the Rennes site has a bad reception. It's my dev device at home... I have a single dipole (300Ohms impedance by the way ;) ) in my office. I'm not the owner of the house, so I don't wish to put the antenna on the roof, but will do in my future house.
Thanks for your return.

Nick

Hello again
Has the project ended? Receivers not online any more? Problems?
Regards,

After some SD filesystem and linux worries  >:(,
the developpement RPI 'Rennes sensor'  is online again... (http://fmbox.ddns.net/home)
Le Mans will come soon I hope but the SD cards are definitly not my friends.
By the way, a friend of mine told me about a nice linux way to quicly install a full system, like a FMBox can be. I think I will work on it to offer an easy way to install an FMBOX. So, if someone is interessted in hostig a FMBOX at home..., just tell me. All you need is a pira P175 (sure most of this post readers have at least one), a working RPI (2) (with sd and power supply), a USB Key, and RPI RS232 kit (like https://www.abelectronics.co.uk/p/51/Serial-Pi-Plus?CatName=0&c=17).
We could even make it an open source solution? It could be fun to build a wild FM monitoring system with our nice Pira boards.
See you soon?

Bye

Nicolas
