[op25-dev] P25 at 800MHz

Hi folks! I don't no if this is the right way to request help regarding op25. Let me try :). I am trying Op25 decoder (scope.py) + USRP. Although I can get the air interface signal, the error rate is too high and the voice signal is rarely intelligible. The radio I have is setup in direct mode in 800MHz (a bit higher than the ones I saw in previous work). Using the signal analyzer app (osmocom_fft.py) I can detect the signal with a high power level using the same antennae and gain settings. I have already run the scope.py (osmocom) and got the audio and radio info. It seems that the scope.py+USRP request a high frequency offset (7.5kHz) to tune the carrier and try to decode the air interface signals. I have: USRP_N210+WBX+tuned_antenna+Ubuntu+GNURADIO-3.6.5.1+OP25_osmocom. May the higher frequency request another setup I missed? Am I missing many details? :) TIA
