Good morning I own a motorola r2001a, it works completely. The only problem that if I go on the frequency counter function does not read any frequency in the RF input. if I try in the connetor bnc vert \ sinad \ dvm \ frequency counter in then reads the input frequency. Can you help me? Thanks so much
