I have a local business's DMR frequencies programmed into my 436 in several ways but I only hear voice on about 5% of the transmissions. I have them programmed in as a conventional system with NAC search on, then as three different single frequency DMR trunked systems - one for each of the three frequencies they are licensed for, then finally as a mototrbo system. The scanner only stops on the frequencies entered as conventional non-trunked. But when it does stop I only hear voice on about 5% of the transmissions. The other 95% of the time it shows color code and slot number but there is no sound. There is only silence. Sometimes the slot number wobbles back and forth between 1 and 2 when there is voice. On the FCC's website I saw that they are licensed for two DMR emissions types - one for voice and one for data. Could it be that the 95% when it is silent are just data transmissions? I do not see "ENC" on the display. Below is a picture of taken during one of the silent times.
The transmisison had just ended when I took the picture so there are no bars on the s-meter. Usually it is maxed out at five bars.
