Telemetry experiments

David Price is continuing the sensors and telemetry experiments and will shortly be hosting a course at rLab. Using an Arduino Pro Mini 328 3v3 with UBlox Max 7 GPS and Radiometrix NTX2B 10mW 474.065MHz transmitter. The aim is to transmit the GPS and other sensor data via RTTY. Currently testing using a DVB-T dongle as SDR with SDR# and DL-FLDIGI.

All happily working at 3v3 but need to filter and buffer the GPS output to cope with the slow speed RTTY.
