I have been fooling with this program and listen to the statewide (RI) P25 system on 800mhz. I can receive pretty good signals but audio is warbly...running my SDS200 side by side with DSDplus on computer, I can hear the scanner audio is fine, but DSDplus audio is sometimes garbled. I have tried adjusting GAIN up and down but no difference. There are 2 settings AMBE and IMBE under the decoding tab. I read somewhere by setting these to a lower value than the default of 50, to 35 would help. No difference. Is there anything I can do to improve audio quality? The dongle I have is an "RTL-SDR" one.
I just did some experimenting with SDRTrunk v5.0 alpha 6 on a local HAM-DMR frequency on 70cm whichis connected to talk group 91 Brandmeister. It worked!
The steps you can do is:
1)Open Playlist editor
2)Click Channels Tab
3)click "New' Then select P25 Phase 1
4)Edit the Info for all three lines anything that makes sense to you. (It won't play until all 3 fields are filled!)
step 4A: Also create a new alias list press save
5)Scroll down Source enter 1 frequency press save
6)Press Play
Enter Talkgroup alias for the alias assigned to that frequency you created in channels tab:
1) In Aliases Tab press the drop down box and select the new alias list
2)Press "New"
3)enter in both fields info in both fields for "Alias" and "Group". Alias is the talk name and Group is the number press save
IF my instructions were good enough it'll listen on that frequency and display the talkgroup.
Do the next for the next frequencies. Take your time!
