(apologies for duplicate post - posted this to wrong thread earlier)
There was significant damage in Austin's Westlake Hills tower farm. Antenna elements have separated, cables snapped, backup generators failed and even the collapse of an older 500ft tower which I understand was the primary for National Weather Service radios. More damage occurred as the ice began to thaw, dropping hundred pound blocks of ice through transmitter buildings. I believe that is what took the main NBC affiliate (KXAN) off the air, and why it is currently on a subchannel of KNVA 54. I wouldn't be surprised if many folks will be running on reduced power or from backup facilities for awhile.
For those of us that remained on the air, and with minimal impact - it came down to luck, and great engineering folks who kept monitoring equipment to keep the ice buildup from burning up transmitters.
They design systems in the north do deal with these sort of situations - not sure it's worth the expense to do the same here, but I'd bet there is some rethinking of this at the moment.
Can't speak to why 590 went down, but it certainly didn't go unnoticed. Have not had a chance to see our Chief Engineer as he's been quite busy in the field. The infrastructure and back up generators at the Waterloo Media building worked as advertised... but we lost Spectrum and phones. In 2023, Internet connectivity plays a much larger role in broadcasting than one might think.
