When using SDRTrunk, All of my P25 transmissions get sync loss for the first frame or two across all TGIDs and Sites. I use 4x rtl-sdr V3's and they all have the same symptom, initial decode gives bad data. I did A test with rtl_test and I got data loss at the very beginning of the test, just like sdrtrunk... It does this for all six of my RTL-SDR V3's, on 3 different PCs, and both on Windows 10, 11, and Linux. I switched USB ports and hub configurations.

Is this a tuner issue? USB Bus issue? It only loses the first few samples when decode first starts. The test ran for awhile without any issues...
