Today's taskforce finished assembling all the new transmitters; on one of these the software installation was done as well already — up and running!

We assembled 7 transmitter housings tonight.
To be continued tomorrow.
One month left until #39c3!

More custom PCBs for the pager system arrived! These header PCB for Pi are for our additional new transmitters so we'll be able to cover all of #39c3.
Designed by one of our engineers.

140m range (double the whole building area!) from these small €8 #POCSAG transmitters to the pagers at only +18 dBm with a UHF coil antenna (there does seem to be quite decent RF groundplane on the PCB).
For those who are curious the TX is an SI4432 controlled by a STC11L04 MCU
