KWBY going to 10kw

[semoochieParticipant]

KWBY 940AM’s application to increase daytime power to 10KW has been granted. If this were 50 years ago, it would be a huge deal but they should still expect solid metro coverage if noise isn’t a factor.

I find some sad irony in this power increase happening after the station has changed its programming from in-house produced offerings that engaged with the local community to what appears to be a complete schedule of paid programs that come in from other markets.

Found a good price on a used 10kw somewhere?

[boisebillParticipant]

And why 10 kw?
The SBE 16 Clays Corner column for October says that Bustos is moving the now un-used night 10 kw 1210 Auburn site transmitter to Woodburn!

That tower might glow a bit at night 🙂

Possibly, it’s the most they can get from a single tower without interfering with KJR.

The tower will not be glowing at night as they will still be operating at the 200W power level at night.

The stations tower is quite short though at only 54 degrees. With an antenna resistance of 11 ohms, they will be moving a lot of antenna current for this power level, about 30A, to make 10KW.

I differ to the master…should’a thought of…

Is that going to interfere with KCOE in Bend?

[semoochieParticipant]

There is no KCOE. They have returned their license to the FCC, the license has expired and the towers dismantled. That’s the reason KWBY can increase power from 250 watts to 10KW on the same tower. KWBY, then KWRC was limited to 250 watts when KCOE, then KGRL was 1KW.

I heard KWBY had always been operating on 1000W day

In case you didn’t click on the link, KWRC/KWBY has always been 250 watts during the daytime. Had they been 1KW, their coverage would have doubled. If I’m not mistaken, their new coverage will be six and a half times their current coverage.

Looks like it’s a little less then four, not six. Almost doubling the radius (by visual inspection)(distance to the contour of your choice 2.0 or 0.5 mV) means area increases by a factor of four. A=πr²

FWIW, I get closer to 7x area.
