The new driveway looks like it could become a ski jump during an ice storm. |
 |
A lower-rez picture from 2000 of the east side of the new
building. This is the entrance to the 2nd floor which has KOPB-TV, -DT, and -FM, and Infinity's 101.9 KINK. As with ALL transmitter sites in the Portland area, bigtime ice shields are in place for antennas and exterior equipment. |
 |
The south door of the new building, which is the direct
entrance to the FM transmitter (except for KOPB-FM) and combiner space. 105.1 KRSK's permanent transmitter room will be in an addition to the left of the existing building. |
 |
One each 2 MW diesel generator. Townhouses to be built soon on the ice shield. |
 |
KGW Engineer Walcott Dennison shows Harris' Walt Lowery the
inside of the generator. It is amazingly quiet, from the outside of course, when running. |
 |
The label on the generator's distribution panel. Even
without doing the 3-phase math, that's 1.44 MW. I like to quote my Junior High "Electric Shop" teacher, Don Stansifer N6RU, who, while teaching us Ohm's law, after someone asked "why aren't there kiloamps?" said: "If you ever see a kiloamp, it will be your last." |
 |
Of course you need a lot of fuel to keep the generator going. |
 |
The old and new towers are only 39 feet apart, center to
center. The new one is the red and white one, while the old and shortened one is now GREEN! (Same as the new building). |
 |
You can see the stacked antennas for KGW & KGW-DT and
KOPB-TV & -DT on top of the new tower. It is NOT a candleabra, it's a PLATFORM
(and the City of Portland signed off on it). Only two corners have antennas.
Both towers have elevators. You can barely see the Shively 8-bay FM panel below the platform, but can easily see the 4-bay 1/2 wave spaced FM backup antennas on the old tower. |
 |
The new building's phone room, on the first floor. This will be the temporary home of the KRSK transmitter. |
 |
Shively FM combiner, looking south. Entercom's KRSK will join KOPB-FM, Clear Channel's KKRZ, KKCW, and KRVO, and Infinity's KINK. You can see the south door in the back to the right, and the window in the back is to Clear Channel's rackroom/shop. |
 |
Combiner, looking northwest. |
 |
A picture from 2001 of the combiner patchbays and power
divider. The output of the combiner and the input of the power splitter is 9" line.
The 6" lines on the output of the power splitter go through a patchbay |
 |
The back of the patchbays and power divider. The 9" line is made out of aluminum to save weight and cost. |
 |
Davicom combiner monitor screen. The controller can automatically switch each one of the stations off of the combiner if there is a problem with the combiner or antenna. |
 |
In another picture from 2000, the original KGW's classic
50's TV transmitter building, which now has just the KGW and KGW-DT transmitters, and has been repainted. |
 |
KGW Channel 8 TV transmitter, a pair of NEC's. Set to be replaced this year by a solid state Harris. |
 |
The right 1/3 of the Harris KGW-DT transmitter, which has
the control cabinet. The other 2/3 is to the left of the column. |
 |
The left 2/3 of the KGW-DT transmitter. This is where 101.9 KINK's pair of Harris FM-25K's stood from about 1981 until they were moved into the new building. The power supplies and blowers were in the basement. |
 |
In another picture from 2000, one of KINK's FM-25K's and a
Continental 35 kW transmitter lived in this temporary-office trailer for a couple
years while the new building was being built. The floor of the trailer was greatly supported from below. |
 |
Inside the temporary KINK trailer. Kind of a tight fit for two transmitters that each have separate power supplies. Plus a 50 kW dummy load, added air conditioner (behind the 25K), coax switch, and desk/workbench. Between the trailer's A/C and the added A/C, it stayed comfortable during the Portland summers. |
