Based on reviewing the FCC website, this is the information that I found. Forgive the formatting, but I have no idea how to make columns. The first number is the current operating level and the second number is the level at which the license was issued.
KETS 1 kW 2.1 kW
KARK 4 kW 989 kW
KATV 10 kW 750 kW
KTHV 27.5 kW 55 kW
KLRT 1,000 kW 1,000 kW
KASN 1,000 kW 1,000 kW
KVTN 10 kW 725 kW
What I am wondering is the differences between the total power output that the stations are licensed for? Is KTHV at 55kW significantly less that everyone else because of VHF compared to UHF? Why would KATV license 750 kW compared to the other UHF stations at 1,000 kW?
Also, why would a station choose to broadcast such a weak signal compared to licensed output when other stations such as KLRT and KASN are using full power. I assume it saves electricity or did the station install a smaller transmitter than would normally be used to save money on equipment.
Just curious. FWIW, KARK and KATV are pathetic with their current power levels. Also, if everyone ever begins using full power, obtaining signal should not be a problem.
