Fire at KICY

L

Les

Guest
KICY (am), Nome, Alaska is off the air after a morning fire
gutted a building at their transmitter site.

The station (religious) runs 50-kW ND much of the day but
goes directional (3 towers) toward Russia during late night
hours.

The site is 2.5 miles from Nome on the Nome-Council Road
along the shore of Norton Sound (Bering Sea). The area
is shrouded in smoke from inland forest fires with visibility
measured in feet and all air transport cut off. There is NO
OTHER transport into/out of Nome except for 4-5 barges a year
from Seattle.

KICY put up all new buildings on the site about 5-years ago
and installed two well-used second-hand towers to augment
the single Magnum tower (259 feet) that replaced on ancient
tower hit by a plane in 1995. The transmitter building
was unstable (on tundra) and was replaced this year. The
Harris 50-kW transmitter was moved into newest building
just two weeks ago, leaving the phasing equipment, ATU,
and pass/reject filter in the building which burned today.
It appears the transmitter shut down properly when the
transmission line burned through but, there being no dummy
load available, that won't be known until it can be
fired up.

When I arrived at KNOM this morning I noted reflected power,
normally 272 Watts, was down to 48 Watts, indicating KICY
was off the air. I also noted a remote reading that looked
odd, so heaed for the am site, just a half-mile east of
KICY. Fire equipment passed me on the road, none of us
moving more than 30-MPH due to the near zero visibility.
The fire was discovered by KICY GM Dennis Weidler who
went to the site to pick up some equipment for repair and
found flames shooting through the roof. He used a phone
in another building to call the fire department. There
was nobody in the burning building which was essentially
destroyed.

Cause of the fire is not known and may never be as the
destruction near the start-point is complete. It WAS
in the corner of the building where the phasing/ATU was
located.

KICY's contract engineer, who flies over from Anchorage
(90-minutes in a 737) had left his home for a 3-week
vacation last night. I'm the only engineer in Nome and
the closest assistance is another retiree in Anchorage
who can't get here because of the smoke. Dennis will be
in touch with his consultants for a temporary design and
we'll try to cobble up something out of KNOM's big
inventory of used vacuum caps and inductors. At least
enough get maybe 10 kW on the air in a day or two;
probably longer.

Meanwhile, KNOM has offered to run KICY's more critical
programming for the remote villages....

This is like radio used to be in the old days. One station
has a problem and the neighbors pitch in.

Wish us well....we're all safe!

Back in 1989 WRRD (the station I now program) was known as WYLO, and burned to the ground after a lightning strike. The towers survived, along with the cables that feed them, and I'm pretty sure the tuning sheds on the north and south towers survived, but the building was totally gutted. Nothing was left. Mind you, this was before my time with the station (it was under different ownership then as well) but our contract engineer has often told me about what went into bringing the station back online. I'm fascinated by the old Collins transmitter that we have at the site that was transferred to the station after the fire. It still works!

I doubt there's much I can do for you from Wisconsin, but I'll do what I can. I know what it's like to be off the air and not be able to do anything about it.<P ID="signature">______________

Thanks for the kind thoughts. I'm at KNOM, the "other" station
in Nome, which as NOT affected by the fire. Waiting now to hear
from KICY as to what help I can give them. Meanwhile, I have
photos taken during the investigation but have no website to
post them on. I'm gonna e-mail a couple to Scott Fybush shortly.
He did a Tower Site feature on Nome, including photos of KICY,
a couple of years ago. Meanwhile, the smoke from the interior
wildfires easing for the first time in days and it's possible
planes might be able to land this evening!<P ID="signature">______________

A step in the right direction to say the least!

Do keep us posted.<P ID="signature">______________

Can't do since I'm at KNOM, not KICY. Will give copies
to them tomrrow and maybe they will post.

I had dinner with Scott last night. If he doesnt have computer access I will give him heads up.

Add me to the list of another Wisconsinite that would like to help where I can!
 
Pictures from the fire...

Thank you, Adam!

KICY has three more picture:

http://www.kicy.org/photoalbum/work05?page=6

there is also one on their home page: kicy.org

Latest update: It appears it may be possible to uproot the
transmission line to the westernmost of 3 towers and couple
it directly to the output of the transmitter and run a
low power ND signal very quickly. There's enough cable to
make the run and the antenna matching circuits for that tower
are in a "doghouse" at the base, so weren't touched by the
fire.

Thanks to all those who e-mailed offers of assistance. It
feels like the KICY staff will be able to handle the short
term solution. We "across the street" at KNOM will provide
any parts we might have and pitch in if needed but we
don't wanna get in the way, either.

At the moment it appears more and more like a "blowout" in
the transmission line caused the fire. It was pressurized
line rather than the foam-filled type it appeared to be
when looked at while still hot!

Re: Pictures from the fire...

Maybe next week I'll dig out the pictures of the WYLO fire in 1989. I'd really like to make it up to the Jackson library one of these days and dig through their newspapers to see if they had any stories about it. The Milwaukee Journal only had a short blurb about it the day after.<P ID="signature">______________

Foam filled vs. Pressurized?

Below in this post is mentioned a pressurized transmission line. Also mention is made of foam filled.

Please indulge this newbie. I have seen both types of transmission line.

What are the advantages and disadvantages to both? I hope that is not to broad a question.

I am currently enrolled in a CIE correspondence course. However, I almost feel I should send a check Radio-Info's way, as I have learned as least as much from this board as I have from CIE. No slam on CIE intended, but this board is VERY educational.

THANKS TO ALL OF YOU!

the old newbie

Re: Foam filled vs. Pressurized?

For a given size of line, air (usually nitrogen rather than outside--humid--air) can carry a greater amount of power than foam line.

At FM frequencies, air line also has less attentuation for a given length than foam line.

At the KICY site, air line was probably used to feed power to the LTU (line terminating units) at each tower, while sample loops probably were connected by phase stabilized foam line. Neither of which appreciated the heat!

The pressurized line was used to link the actual transmitter
output to the combined 850 pass/780 reject filter, phasor,
and antenna matcgubg in a separate building a
couple of hundred feet away (the building from which the
xmtr had been moved just before the fire). It was
within 15-feet of the center tower of three and had
previously the xmtr had been directly connected to the
ATU thorough a very short line. The feeds to the other
two towers carried very low levels of signal. The actual
feed to the center tower was copper tubing through an
insulator in the side of the building.

The sample loops were connected with approximately 1-inch
foam-filled flex. It was the primary feed to the ATU
from the transmitter that appeared to have "blown out"
just above floor level directly under the shelf that supported
the ATU components. The only transmission (or sample) line
which sustained damage piercing the outer conductor. The
inner conductor of that line was pretty well destroyed, too.

At the KNOM site I'm using non-pressurized rigid line to
link the 25-kW Nautel to the Kintronics ATU, only about
30-feet. No worry about power handling; it was salvaged
from a TV transmitter site where it was routinely used
with just shy of 100 kW. Out of the ATO we link to the
folded unipole skirt through a short chunk of copperweld
(flexible uninsulated, unshielded cable).

Are they back on-the-air at full power?
