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
