1110 AM now at higher power

It's official, KVTT is now licensed and operating at 50,000 watts. I know, big deal.
 
I have a real dumbass question. Be gentle now.

Does a 50,000 watt transmitter use 50,000 watts of electricity to operate? So if your electric rate is 8 cents per KwH you get 50,000/1,000 * 0.08 or $4 per hour just to keep the xmitter on?
 
Speaking of power upgrades, is the Ticket up to 25kW yet?

A 50,000 watt transmitter doesn't use 50,000 watts. It generates 50,000 watts of RF output. I think. I'm not an engineer and don't play one on tv.

Seeing as how one can't cheat physics...and that nothing is for free...if an AM transmitter truly produces 50,000 watts of measured output RF energy, it most certainly requires more watts than it produces. It would be wonderful if transmitters were 100% efficient...but there we go again with that "can't cheat physics" thing. Today's modern AM transmitters my be close to 80% efficient, with the rest being lost as heat. And yes, the electric bills for transmitter sites can be huge.

On a similar subject, the typical 100,000 watt FM transmitter is not truly producing 100,000 watts. It's usually more like 20,000 watts of raw RF energy. The 100,000 figure occurs from feeding an antenna that has "gain." The antenna reduces the power in one direction, effectively producing more in another typically, the vertical plane, concentrating the pattern more towards the horizon. Hence the term "effective radiated power." As Ross Perot once said, "I could explain further, but it would take charts and graphs... "

Speaking of large electric bills, here's some trivia: The average electric bill for Cowboys Stadium is close to a half-MILLION dollars per month! Jerry, you have bigger problems than Wade! :)

Canned country. Same old same old.
 
Kind of funny to hear drinkin' and cheatin' songs on the KVTT call letters. ;D

Actually, I like the music. A huge playlist it seems. They just played Lyle Lovett's That's Right, You're Not From Texas.

I am in far west Fort Worth, in their deep null...barely can pick it up indoors over the hash. Who are they protecting, 1110 in Houston, or an adjacent?
 
And also, to a lesser degree, KHFX 1140 Cleburne. They're right in the path of that nasty null.
