THE TWISTER

Rumor has it that The Twister is in the progress of raising their power to 100,000 watts, it was 90,000 watts according to www.radio-locator.com. I got a strange feeling that they'll flip formats before too long.
 
They're really not increasing their power for the main transmitter. The 100kW you mentioned is the ERP of their auxiliary transmitter. The main transmitter has an ERP of less than 100kW because of the height of their antenna above average terrain (above 1986 feet, the maximum for a Class C station using 100,000 watts). Under the FCC rules it you exceed the maximum height (HAAT) you have to reduce your ERP accordingly. The Twister's back-up transmitter uses the same tower, but runs more power because their antenna is situated below the main antenna. The result is virtually the same coverage.
 
Probably fixing all the dead spots throughout the metroplex, I guess that's what it means
 
No. We're talking about a back-up transmitter using a separate antenna on the same tower, with about the same coverage, in case the main system fails (lightning strike that fries the antenna, trouble with the transmitter or whatever). It would be used only in that situation, not to fill in gaps in coverage. A back-up transmitter (and antenna) is just that: it keeps the station on the air.

Back-up transmitters on the same tower are a real bad idea. Just ask the folks who worked at the now-departed Young Country. That station never really recovered from losing both their main and backup transmitters when the KXTX tower fell in 1996. They used the soon-to-be departed KEWS 94.9 frequency for a while then got on with a much-reduced power on 105.3 for months before they ever got a full power system back on the air.

The disruption caused about a 30% drop in ratings. I think without the disruption that format would have lasted much longer than it did.
