I'm trying to add a P25 system do I put control, control and alternates, selected, all then below that single or each frequency

Motorola system: all control channels; L3H system: all channels.

How do I setup airspy r2

 

[maus92]

Plug it in. It should be recognized automatically.

It's showing up on device manager but not sdrtrunk

 

[dave3825]

Unplug it to reset it, then restart SDRTrunk

How do scan more than one site should have them in the same create list and set the sensitivity

How do scan more than one site should have them in the same create list and set the sensitivity

Go to your playlist editor, select the sites you want to scan and click "Play". Only caveat is all site frequencies need to be within a 10MHz bandwidth spread so in other words for example you can't scan a site containing 700mhz & a 2nd site containing 800mhz frequencies at the same time with only one SDR (Airspy R2 in your case)

Do I put all the sites in the same create channel list and alias also I haven't calibrate the R2

 

[Bonkk083]

That must be what's wrong for as calibrating the R2 haven't seen anything how to do it

 

[Bonkk083]

Which one is correct, On the left I did frequencies to all and the configuration to single, then on the right I did selected and for each frequency

Not sure where your getting calibrate from, but until you fully understand the way all of this works, I would not even attempt to calibrate the Airspy. If your meaning the PPM adjustment in SDRT, then that can be safety adjusted.


Lowest freq on your pic is Spartanburg 851.0375 site and the highest is Laurens site 860.8125. That spans like 9.77mhz. If you get exactly 10 on the R2, you will be good. I do believe I read the R2 does 10mhz total and 9mhz alias free usable.

Neither are correct. It looks like you are trying to program a trunked system as a conventional system. When you create a new channel, select P25 Phase 2 Trunked system.

Perhaps the OP is referring to the "CPU vector calibration" found in SDRTrunk user preferences?

That's what I was talking about

Do I add all frequencies or just the control channel

For P25 you can get away with just the controls & alternates. For DMR (MotoTRBO) & everything else you'll need all frequencies

Like this, with the max channels is that how many channels in each site, on the channels page it has new and different decoder

I got it working but it's getting all of the alias for the counties I have in after I put in the ones I wanted
