MotoTRBO, that is. Couldn't have been any easier. Connect the d-tap to the mic port, open DSD, wait for people to talk.

Only trick I needed was the -xr option to tell DSD to expect inverted TRBO. Wouldn't decode without it, but with the option it still doesn't decode fully:

This is 461.4625. It's quite active. Of everyone that's licensed I only see one that is licensed for TRBO--MasterPark. They're too far away for me to be getting a five watt base, so I have no idea what I'm hearing.

35 watts out of Des Moines? Doubt it.

I can't tell if you're being facetious.

It was just gibberish when I downloaded it. Think they're utilizing the encryption?

Yeah, gibberish is exactly what I'm hearing. It does not sound like P25 enc.

Perhaps someone with a TRBO radio (installed or not) would like to use their radio to listen in and see if they're getting the same. And I need to find some more TRBO.

I think we deduced a while back that the Bravern in Downtown Bellevue uses MotoTRBO.

There are videos on YouTube of people using DSD to decode TRBO. I would post a link if I wasn't on my phone right now. So even though Jim posting that link that TRBO can't be monitored, it can.

Yes, I remember. Which one(s) in particular? I assumed you committed them to memory.
