Happy April!

Hi, everyone…

Spring is finally here and the snow is starting to melt here in Laramie (that is, until we get another good dose of it just to remind us that we are in fact still at 7000 feet).

I just installed a new version of WordPress here on my site which includes some really cool ‘gallery’ features for photos and media. Unfortunately, I can’t seem to get them to work so I’m going to have to keep using my existing photo gallery for the time being. I’m sure it’s something really stupid like the version of SQL running on my server. Hope I can get it fixed soon.

As I promised earlier, I WILL post a few more stories once I get a chance to sit down and upload the pictures.

Later!

(Update: Looks like the new gallery functions are working as of tonight’s WordPress build…Guess I’ll leave it this way until they put out another ‘official’ release of WordPress. In the mean time I’ll work on taking advantage of the new features now that I have them working.)

New software version…Gallery test…

I just upgraded the Wordpress installation on my server to version 2.5. This version is supposed to have enhanced media handling capabilities (among other things). I am going to try out the gallery function by including some pictures of my visit to the KSJN transmitter site in Saint Paul last year. I was involved in the very first HD Radio transmissions from this plant and put the first HD Radio multicasts on the air in the MSP market on this station.

(photo gallery SHOULD be here if this works…)

More soon…

Hi everyone…I realize it’s been over a month since my last post. Once again I’ve been pretty busy and haven’t had much time to write. To make things even more interesting, I was kicked out of my shop for much of the week while they remove the asbestos (I only wish I was joking).

Wild Wild West Engineering

Posted by Shane on February 19th, 2008 at 11:35 am

This has to be one for the record books…Most engineers drive to their transmitter sites in a truck.  Some take a snowmobile or snow cat when a truck won’t make it through.  Others can only get to their transmitter sites with a helicopter.

Sometimes we just have to do things the old fashioned way out here in Wyoming…By Horseback!

Late last week, I received a call that our site on Copper Mountain (91.3, KUWT) was off the air.  The transmitter was on but there was no audio.  This could be caused by one of several things, the most likely being the satellite receiver or dish.

We had just suffered a severe snow storm and all of the roads around the state were closed.  On Friday, we were finally able to get out on the road again but had no way to get up to this particular mountain top.  Copper Mountain was snowed in and would be until about April or May.  There was no snow cat available to get to this particular site.

Our Program Director keeps horses and offered to help us get up to the site by means of horseback.  I decided to take him up on the offer.  Since I was busy fixing ANOTHER one of our transmitter sites that went down during the severe weather, I sent my assistant up to the mountain with him.

They left for Thermopolis (the closest town to the mountain) on Saturday.  On Saturday evening they boarded the horses for the night and headed for the hotel.  Sunday would be a full day of riding up the hill to the site, fixing the problem and then riding back down.


Getting ready to unload the horses for the evening…
“Buck”, a gray Percheron gelding pokes his head out of the trailer


Horses comfortably boarded for the night at the Bar None ranch near Thermopolis.

The next morning, Reid and Roger headed out from Thermopolis for Copper Mountain.  The road through the canyon was icy in spots but they managed to make it through.


Icy roads through the canyon…


Finally arrived down at “Birdseye Pass”…Gateway to Copper Mountain.


Heading up the road to the site as far as possible with the truck and trailer…


Looks like as good a place to unload as any…


Reid unpacks the gear (tools, spectrum analyzer, spare satellite receiver)


“Pepa”, a light bay mare hauls the equipment


Reid starts up the trail on Buck.  Major drifts!  The truck wouldn’t have made it through this…


Almost there…Lots of wind!


Roger rides Billie, a dark coffee colored mare while guiding Pepa up the trail.


Up at the site, horses hitched to the tower.
Standing next to the building gives them some relief from the driving wind.


Roger stands outside the shack with the horses.


Look at the ice on the tower…Brrrrr!


Reid starts investigating…No signal on the satellite receiver!


The dish had blown off point…
Reid adjusted it while Roger gave him signals from inside the shack.
It was literally so windy that they could not hear each other.
A series of “whoop” signals was used instead.


Success!  Time to get out of this icy wind…


BRRRRR!!!!!


Finally…Heading back down.  Plenty of drifted snow on the trail!
At least the skies are starting to clear up…


Loaded up and on the way back to Laramie.

Thanks to Reid Fletcher and Roger Adams for a bit of Wild Wild West engineering!  When all was said and done, it was a 2 hour ride up the hill, 2 hours at the site and another 2 hour ride back down.  This doesn’t even include the 10 hour round trip to Thermopolis from Laramie…

HD Radio Fun

Posted by Shane on February 9th, 2008 at 10:30 pm

Since I happened to be in Minnesota, I hitched a ride with 3 engineering colleagues from the area who were driving to an HD Radio seminar at Harris in Quincy, IL.

Much of the material was review for me but it was a good chance to get together with a number of my engineering peers from various stations and backgrounds.  It was also good to meet up with a number of people from the factory.


Studying hard or hardly studying?
(At lunch time it’s probably the latter!)


The class poses for a picture


Yours truly poses in front of a pair of transmitters.
The rack on the left is an HD transmitter.  WPR owns 4 of these boxes in various configurations.


More HD related equipment.
The rack on the left is a completely self-contained 3000 watt HD transmitter site,
ready to go out the door to a customer.
The next rack contains various monitoring and remote control equipment.


This is a low power transmitter capable of 1000 watts.
WPR owns 8 of these boxes.
The cover is removed to show the class the inner workings.


Back to class…
Terry Cockerill (FM Applications Engineer, Harris Corporation) shows the class how to properly measure the HD signal on a spectrum analyzer.

Once we were done with class for the week, the four of us who had driven to Quincy together took a tour of the other broadcast equipment manufacturing plant in town.

This transmitter is completely modular and very small for its power level.

Mark Persons stands in front of a very large bank of transmitters destined for use overseas.  This particular setup contains 3 transmitters with 1 fully redundant transmitter capable of backing up any of the other 3.
