• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

This partial statement was made in one of DSDAuther's comments before he went silent.

"Those that are having trouble decoding DMR/MOTOTRBO, if you can provide a .wav file in 48k/16bit/mono from your disc tap of the signal I will look at it. DSD currently only supports repeater output signals so if this is not a repeater output that might be the issue."

My question is this: What is the difference between a repeater output signal and a radio output signal? I
can only think of 2 answers, a: signal strength b: data is not the same. I have never worked on a repeater
system so I have no practical knowledge to go by.

If it's anything like ProVoice or P25, the sync bits are different so DSD doesnt realize is is a signal to decode. With a GOOD clean wav file to analyze, one could easily adjust the sync bits to work with repeated/simplex digital voice.

Signal strength is a factor but I would not say it is the reason you are getting no decode.
