Radio repeater low cost with FM transmitter receive with RTL SDR
Testing of a radio link / radio bridge rtl sdr at low cost. Using an FM transmitter to resend various digital modulations and using RTL SDR with SDRTouch for reception. SSTV decoding with Robot36 and VOA decoding with Tivar. Android device used is a One Plus One.
you can best the receiving technique with minor modifications and devices, the use of an audio adapter for the mobile phone in order to split the microphone and headphones in order to reinsert the sound from the headphone into the microphone (note that an additional modification might be required with resistances to overcome audio bug due to various Android OS smartphone or various versions or standard audio)
