***Unfortunatly the audio bleeding into BPD from MBTA Ops is likely due to badly made USB devices and grounding. Unless I remove the MBTA Ops feed or move it another device it will be there. I did turn off AGC to prevent it from being boosted. Please let me know if this causes issues with the BPD audio***

The intermittent disconnects should be solved. I will be keeping an eye on them. A new antenna has been installed so B-2/B-3 should be comnig in clearer. I also moved the scanner and server so interference from TXing should be mitigated.
