SDRtrunk help

- Start date
what type of SDR are you using? if you are using a dongle type, you will need two of them to get started out with.
This is not really a General Scanning Question, you would probably get better responses posting it in the Voice/Control Channel Decoding Software forum.
Just click on report in the bottom left corner and ask for it to be moved. Please don't start a new thread, as double posting is discouraged.

Have requested for it to be moved. Cheers
you will need two. One will monitor the control channel and the other will fetch the talk frequency it's looking for.

Cheers. Will sit down on days off and get into those videos.
If the winusb drivers are installed on a Bulk-in interface, the SDR may not work for every program. The driver should be installed on the composite device.
Since the OP stated sdrt is not seeing the sdr dongle, but sdr# is, that should be a driver issue. The advice from @maus92 should clear that up.
The OP also has not stated what system he is trying to monitor, so telling him he needs 2 dongles is a bit premature especially since the problem he is having seems driver related. He may need more than one, or he might do fine with just one.
The number of dongles required is based on the spread of the site he is trying to receive. I monitor a trunked system that spans 2.4375mhz and use a single nooelec dongle (running @ 2.56) and have it recording up to 10 talk groups simultaneously with no problem.
Until the OP states what he is trying to monitor, the number of dongles needed is really unknown.
I also monitor two other systems in sdrt, one being 4.075mhz and the other being 3.85mhz and they are both being handled by one airspy mini running @ 6.00mhz since the freqs on the smaller are actually inside the lower and upper of the larger system. So in the end, I am using 2 dongles for 3 systems.
If he was able to get the program running, locked on a control channel and was missing calls, and seeing in the event pane that tuner was unavailable, that would lean towards needing another dongle to cover bandwidth. But my take is that sdrt is not even seeing the dongle.

OK. so I havent got any particular frequencies to monitor as I am learning on the fly. As most do! So how do I get rtl to run on this programme. People seem to assume that everyone understands computers and programmes. I dont. That is how I learn. By doing, As most of you guys.

How? Sorry its all new to me. 50yrs old and have FA tech experience
SigintOS: A Linux Distro for Signal Intelligence
Recently we've heard of a new Linux distribution called SigintOS becoming available for download. SigintOS is an Ubuntu based distribution with a number of built in signal intelligence applications for software defined radios such as RTL-SDRs and other TX capable SDRs like the HackRF, bladeRF...

Since you already have zadig installed, scroll down to Open Zadig.
NooElec NESDR Mini 2+ Al: 0.5PPM TCXO RTL-SDR & ADS-B USB Receiver Set
i just bought this, Dyslexia is a issue with me, i download sdrsharp, down load zadig, install rtlsdr i am now lost airspray when i press play nothing found? sorry neewb here
Just checked my installation of SDRTrunk along with drivers from Zadig. The driver that is set for my RTL stick is the WinUSB driver set. I am able to open sdrTrunk and run it just fine. I think if I installed the other drivers, libusb, it doesn't see the rtl stick. I could be wrong though as I haven't changed things in years on my system as it works.
Edit: I just switched to try it, libusb-win32 (v1.2.6.0), and it opened, found the RTL stick. Best way to see when you open sdrTrunk is watch the commands that scroll through the cmd window. You will see in there if it found it.

Also, if you can't catch it all scrolling past and the main GUI window opens above it, just click on the CMD window in taskbar and it will bring it back to the front. Then you can scroll back to see if it actually found the RTL. Somewhere I saw how to setup Zadig with these correctly as I know you have to click on the Options tab then make sure List All Devices is checked. You then apply the drivers to the RTL but only to the ones ending in like (0) I believe. I think Unitrunker takes the WinUSB drivers for some reason so that is why I had my setup with the WinUSB drivers but sdrTrunk worked also.
NOT to the ones ending in zero - this *may* work with some programs, but not all. You should apply the driver to the composite device. The composite device is RTL2838UHDIR as seen below:
Ahh yes, that is what I was trying to get at, just could not remember exactly what it was. Thanks
