The testing and analysis over the past few days revealed the need for additional repair work in order to get back to normal operation. A multi-step plan is in motion to regain broadcast range while more parts are fabricated.
Tests from the previous night confirmed that we could safely put WGBX, WBZ, WCVB, and WSBK back on the upper main antenna at about 40% power. That move was completed yesterday. And despite the reduced power, the effective reach covers approximately 95% of our over-air viewers, which is significantly more than we had on the temporary antenna.
Next, sometime this morning, the stations will switch positions on the main antennas – WGBH will move to the upper antenna at full power, and WGBX and the networks will move to the lower antenna, also at full power. Again, based on the previous night’s testing, running WGBH at full power alone on the upper antenna is below the power threshold that the four stations combined (WGBX, WBZ, WCVB, and WSBK) would be on that antenna.
If this works as planned, and no reflected power or other issues are exhibited, the stations will stay in this configuration until after the Thanksgiving holiday when new parts will be ready. However, should problems develop, the stations will have to revert back to the previous configuration on the temporary antenna.
The issues that the tower crew, engineers, and station staff are managing are extremely complex, and they are doing everything possible to resolve them as quickly and as safely as possible. We’re sincerely grateful for the continued patience and understanding of all of our viewers who have been affected by the outage.
