Channel 24, WTAT-TV, runs 180KW into nitrogen-pressurized, rigid
transmission line. ERP is 5 megawatts at 1900 ft. It's the FOX
affiliate, here.

Exciting things happen when 180KW of 500 Mhz RF flashes over inside 6
1/2" hardline if the nitrogen goes away.......some of it involving
$30,000 4-cavity klystrons taller than a man.

It's not pretty.....

I have some friends in Charleston running only 1000 watts on Channel
12 from a little solid state Taylor (English) transmitter at 380'
broadcasting Telefutura and local Spanish programs. The whole TV
station is about the size of your refridgerator...(c; They used to
have a remote studio, of sorts, about 9 miles away linked with 10
watts on Channel 26 UHF pointed at the transmitter with a dish. The
"custom" receiver for this TV station, down at the transmitter
building shared with pagers, businessband, etc., was a genuine
Panasonic VHS tape deck tuned to Channel 26. If things at the studio
went awry, one only punched PLAY on the link receiver to get the
canned spanish movie on the air. The VHS cart would give you 4 hours
of canned programming to get whatever blew up fixed....hee hee.

Low Power TV is a lot of fun. I work for them for nothing because
they run on the bleeding edge of bankruptcy. That's why they don't
have a "studio" any more. Something about "rent payments"....(c;
Panasonic link receivers are $59 at Circuit City, if you need one for
you broadcast station. Ask for Mike and tell him you want one like
WJEA-TV uses....(c;
