This is a known issue. I just shut that feed down - it was never any good anyway. The transmitters for those sectors are not at BWI, where our equipment is.
We hope to have a new feed for those sectors in the next couple of months, closer to the relevant transmitters.
The other issue is that we can't get access to the facility where the receivers are at this time due to COVID-19 - so even if we wanted to fix the receiver (which may need to be replaced) we can't.
Thanks for the report.
