go tune you up some channels and see if you got it all runnin

 

[john56]

OK...I have to wait for the Sheriff's Office to talk........

John

 

[j0atm0n]

you on a control channel or voice channel ?
you listening to a trunked system ?
using unitrunker ?

 

[john56]

Listening to a DMR System that Wood County Sheriff and Bowling Green Police switched to....now
on the Bowling Green Channel..just got a data burst..screen says all data...so I assume no voice was with it at that time...

maybe try some mototrbo business in the 450- 460 range that might be more active

 

[john56]

OK...still getting motorboating, no voice..however the DSD Event log is showing talkgroup numbers...did not get that before

John

are you seeing cache errors etc in the dsd interface ?
you may have to adjust the levels and reduce your bandwidth window lower

 

[j0atm0n]

decoding seems to work alot better with lower sample rates ,
i keep mine around .900001 MSPS - .25 on weaker distant signals .
look at your wave form window of dsdplus make sure its in a happy state of
mid levels no peaking - not to quiet - and right in the middle of the window

 

[john56]

I am seeing cache err in the scrolling....I adjusted my line in level down to 24 it was at 94...don't know
if that was the issue...will see

How do I adjust the bandwidth on SDR?

John

 

[j0atm0n]

gear symbol up top that opens the controller options ,
where you can adjust rf gain and agc ,

adjust the sample rate lower
older slower systems might not be able to process higher rates
in a efficient enough manner to decode the audio without errors

 

[john56]

IT is showing saved groups, etc in DSD Event Log, never got that far beore, but still no voice, just that data noise

John

 

[john56]

No luck...while it was transmitting, I set the Rate all the way down to 1.024 from 2.048

ok next few things :

on the sdr# plugin if you select "mute this frequency" it will kill the audio noise your hearing but will still pass audio to dsd+,
( it basically just sets sdr# to mute every time your on that selected freq )
& it will save that frequency info in a digital_frequencies.xml file for future muting,

next :

open up your volume mixer on windows and double check that dsd + volume level is turned up.

and also you can turn down the volume for the virtual audio
( just check and make sure it doesnt effect the levels that dsd+ is hearing )

 

[john56]

Do you check the box in DSD Plugin for "Enable aux audio output"?

John

 

[j0atm0n]

try .25 ( or your lowest sample rate )

also :

click on the dsd plugin configure option again up top there's a decoder option tab ,
check it over , I use the "auto detect" option .

 

[j0atm0n]

yes enable aux audio output

 

[j0atm0n]

ok little hind sight here , since i know your using the plugin now ,
make sure that sdr# is set for audio output to your speakers and not to virtual audio
incase you might be double feeding same audio into dsdplus 2x

 

[john56]

Everything checks OK...while they were transmitting, I set the symbol rate down to .25 still no voice.
Audio level is up on DSD in volume mixer

just by chance are they encrypted ?
