That looks all good with DMR Decode, and assuming the disc tap is correct all looks good with DSD too.
I'm uploading two more video examples of two other systems which I'll post here as soon as they're ready, one is a busy system with lots of voice (UHF) but they also have a databurst every 30 seconds which is common with TRBO systems. The other is the one that I said transmits most of the time about 95% data and 5% voice (VHF).
Are there any other local systems you could try as it looks like you've got everything set up correct?
