## Tuners
### Unable To Source Channel From Preferred Tuner
What does this error mean?
```
2024-12-02 21:18:21.412 INFO i.g.d.s.t.m.TunerManager - Unable to source channel [851187500] from preferred tuner [RTL2832 SDR/R820T 00000001] - searching for another tuner [572MB/630MB 90%]
```
It means that you have selected a preferred tuner in your channel configuration for your control channel and sdrtrunk is trying to also allocate a traffic channel for that same tuner. However, sdrtrunk can't allocate the channnel/frequency from the preferred tuner. There are two possible reasons why this happens:
1. The preferred tuner is already tuned to another frequency and it can't fit the new channel together with all of the current channels within the tuner's bandwidth.
2. The preferred tuner that you selected in your channel configuration is no longer available in the system.
In the first issue, sdrtrunk will search for another tuner for the traffic channel. If it can't find a tuner you'll see a call detected event where the details indicate NO TUNER AVAILABLE. The solution is to add another tuner so that sdrtrunk can tune the additional traffic channel.
For the second issue, you can select another preferred tuner in the channel configuration so that sdrtrunk stops trying to find a non-existent tuner.
