Installing a New Repeater

On Sunday, ARAN put in it’s first of  4 new repeaters in our network.  We are replacing some old equipment including the duplexers.

At this site we replaced the duplexer and the repeater.  We are using new Bridgecom repeaters with Cat 400 controllers.  This site was using 2 antennas with the Tx antenna at 60 feet.  With the duplexer, we are now at about 180 feet.

The range now is a lot better than it was.  Kind of fun getting in the middle of this, haven’t done this type of work before.

The Sienna is finally on the air

I got the Sienna on the air last Monday.  I am still waiting on the 100w amp and the embeded PC, but we have been hitting PSK hard all week.

I have made a little over 20 contacts with it since.  Great performer and a fun project to build.  I plan on taking it camping as soon as I get the embeded PC put in.  That way I only have to take the Sienna, a monitor, keyboard and mouse with me.

You can take a look at the build at http://w0wwv.org/index.php/board,21.0.html

So if you want to see what it sounds like at least on PSK you can usually find me at 14.070.  Contact me if you want to try a SSB contact.

SDR and WinRadio

After my post the other day about SDR, Dave KØRWM contacted me about his experiences with SDR.  He was gracious enough to send me a DVD of recordings he made using his SDR setup.  He also included instructions for downloading WinRadio from http://winradio.org.

I have to say I am really impressed.  The audio quality is very good.  He uses an Elektor SDR and a USB Sound card for a total investment of less than $250.00.  He has since ordered a RF Space SDR-IQ that costs around $500.00.  Not a bad price for such a high quality receiver.

As soon as I get some more of my other projects out of the way, I plan on playing with more SDR stuff.  There is a lot more I can do with Winradio not to mention the PowerSDR software.  The thing I like about it is the low cost of entry.  When you look at the price, a new ham can get into this stuff for less than the inflation adjusted price of my old Heathkit HR-1680.

Thanks again to Dave, that is what I love about Amateur Radio.  Just ask, and somebody will step up to help out.

Why we need Amateur Radio

Windstream, the local telephone company in Hastings and the surrounding areas suffered a malfunction in some of it’s switching equipment located in Lincoln, NE yesterday.  The area was left without 9-1-1 service for most of the day.  Here is a quote from the Lincoln/Lancaster 911 Center:

quote:

“Julie Righter, Communications Manager for the Lincoln/Lancaster County 911 Center, verified Thursday evening that landline telephone service to 911 had been restored. Cellular service into 911 was still not operational at that time. Until 911 services was fully functioning, it was suggested to continue to use the seven digit numbers listed below to access emergency services. Those numbers remained active until all service was restored.

The public could also go to local fire stations and Ham radio operators were posted at many major intersections in Lincoln to deal with emergency situations.”

Hastings/Adams County Ham’s help was not requested, but it does highlight the need for planning for situations like these not just severe weather.

New Repeater System

We have been working on a new set of repeaters for the ARAN club.  We decided on Bridgecom units with Cat 400 controllers.

Our next problem was how to get them on IRLP.  We currently have two IRLP Nodes on simplex (3258 and 7438).  At least one of those will go on a repeater.  Then we were going to put nodes on the other repeaters also.  Then we got a bright idea about putting it on just one of the repeaters.

We have 5 repeaters and we link them together though one repeater that is in the center of a spoke.  That repeater acts as a hub for the rest.  I posted a message on the IRLP mailing list yesterday and received many good comments from the other users.  It looks like this might be an ideal arrangement, so the next step is configuring the controller for the IRLP node.

If you have any experiences with something like this, let me know.

Role Models

I am not one to use the terms role model or hero lightly.  In today’s world, those terms are thrown around so easily and applied to Hollywood celebrities and sports figures, it demeans the use of the terms.

We all have them however.  In my life, other than my father, one of the most influential people in my life was also one of the most humble and unassuming persons that you would have the fortune to meet.  I am refering to my uncle Ray.  He never married, never had kids, didn’t get rich and wasn’t a powerful politician.

He did however make a difference in everyone’s life who meet him.  He was a prolific letter writer.  If you were lucky enough to get one of his letters, you knew right away that it was written by someone who had a unique insight into how humans related to each other.  He had an incredible memory and used it to record and pass along some of the most interesting “Tall Tales” that were told on the Great Plains of America.

As a testament to his enduring friendships, two weeks after he passed away, I received a phone call from the VA hospital were he had been.  On the other end was a WWII friend of his in his 70’s who had driven across the country by himself to see his old friend one last time.  I invited him over to my house and he spent several hours that evening telling us stories about my uncle and his selflessness that endured him to all of his buddies in the service.  As was his custom, my uncle had never bragged or related any of these stories to us in the years that followed the war.  Even in his death he taught me invaluable lessons about friendship.

So you are probably asking what this has to do with Amateur Radio.  Well the other day I was out working on a new console for some of my radios.  I came upon an old Hallicrafters S-38 that my uncle had given me.  You see he was a Radio Corpsman during the war.  I was always amazed at the old S-38 and it got me interested in electronics and although Ray was never a licensed Amateur, he encouraged me to get my license.

So one of my next projects will be to restore the old S-38 and get it working like new again.  Then every time I fire it up, I can honor one of my first role models and I am not ashamed to say one of my hero’s.

IRLP Node Administration

I administer the IRLP Nodes for the Amateur Radio Association of Nebraska.  We have two up now and plan to add more.

I stumbled upon K6IB’s neat IRLP Control Software last night and installed it on the two nodes we now have up.  Neat stuff, this is what I love about Amateur Radio.  Hams helping Hams.

When you have time, slip over to http://w0wwv.org and in the right column you will see an IRLP Status box.  If you click on the link, you can view the real time status of our nodes.

Thumbs up to Brent – K6IB http://k6ib.com for this great contribution.

Weekend Shack Cleaning Results

I spent a couple of hours this weekend cleaning the Office/Shack.  I am always amazed what can happen in there over a few months.  I found about 10 pens and a couple of tools that I had been looking for the past month or so.

The main thing that I came a crossed was a shelf I purchased last year from Richard Robinson K4EIH/G  (www.Novexcomm.com) that would allow me to mount my two Motorola radios side by side in an equipment rack.  I started building a rack out of reclaimed wood and didn’t get it finished yet.  So they have been sitting on the floor getting dusty and kicked around.  So I went ahead and put them on the rack and they are laying on top of the power supply right now.  At least they are not getting kicked around any more.

This in turn led me to work on the rack.  More on this later.

So instead of running out on the weekends to buy more stuff, sometimes it is cheaper to find old stuff in your shack and finish those half finished projects.

Looking at SDR

The other day I was checking out the ARRL website and I read Stan Horzepa’s, WA1LOU column Surfin’: Hamming on the edge.

Since I am a computer guy, SDR has always intrigued me.  I have been looking at sticking my toe in the water for awhile, but didn’t want to spend a lot of money.  The softrock stuff looked good, but I didn’t want to be stuck on one band.

Stan had a link to http://garage-shoppe.com/wordpress/ , so I followed it and started reading about Pete Goodmann’s LD-1 SDR receiver.  The price and performance look good, so as soon as I get the Sienna done, I might order one and start playing.  I looks like it might be a good match to the Sienna for a Pan-Adapter.  We will see.

Sienna Project Build Update

I (with some help from Brian of DzKit)  have the transmitter working.  I will try to get some video/audio put up next week of it on the air.

I really feel bad that I have taken so long on this, it shouldn’t reflect on the quality of the kit or the support Brian offers.  Our business just flat out got swamped starting last September/October and has just now slowed down back to normal.  I am not complaining, especially in these economic times.

So I am really excited to get it on the air.  I will try to make some contacts with it, and then build the 100w amp.  I also ordered the front panel and the embeded PC.  If the timing goes right, (no guarantees) we will use it for this years field day at ARAN (WØWWV).
