WGBH-TV coverage after August 2

[Michael Malone]

Is it technically possible for WGBX to add an HD signal from WGBH and still maintain the HD signal that WGBX allots to NBCBoston 15?

I expect the 2.1 programming will end up being transmitted over WGBX's UHF
signal, sooner or later.

I also expect the VHF 5 signal will become WGBH's test bed for ATSC 3
experimentation.
