RadioSPECTRAL PTRX-9700 Panadapter UHF band monitoring with DMR decoding for ICOM IC-9700. RF-out signal provided by PTRX-9700 is digitized by RTL-SDR and 4-FSK signal is demodulated by GQRX software. Finally audio output of GQRX is transferred to DSD+ DMR decoder via virtual soundcard. Result is clean and robust DMR AMBE+2 audio.
