Micro controllers

One of the main reasons that I got into Amateur Radio way back when, was that I liked the idea of building things. In the late ’70’s, that meant electronics. I still remember seeing an issue of Popular Science or Mechanics, I don’t remember which one, that had plans to build a phone answering machine. That was back before our consumer electronics crazed society where you can go to the local Walmart and pick one up for $20.00 bucks or less.

I was 12 or 13 and didn’t have the skills or money to build it, but it fascinated me. A couple of years later, I found Amateur Radio and that ended up leading me to computers and the rest is history. So fast forward to today. We have had a couple of decades of the US making money on money (the financial industry) and we have sold off (out) the manufacturing and engineering base of the country. To be honest with you, I have been looking at this and have become pretty pessimistic about our future.

Then I start researching on the Internet (something we haven’t completely sold out) and I come a-crossed Arduino. This is what I remember the US being when I was a kid. People building and experimenting with stuff in their garages and basements.

There are all kinds of things we can do with these things. Not to mention their applications in Amateur Radio. So I bought a board on ebay, and I plan to start playing with it. It combines my interest in programming and electronics. I have a couple of ideas for things I want to try and make, so let’s see what happens!

This is the kind of stuff that will turn the fortunes of the country around. If we want jobs, we need to nurture out entrepreneurial spirit in this country again, and not export the manufacturing of them off shore.

America Needs Jobs

America is one of the most dynamic and ever changing experiments that has ever taken place in our known universe.

I don’t think I am going out too much on a limb making that statement. In these fast changing times, I think that only the United States of America has the ability to make the changes necessary to retain it’s top spot, politically, economically and morally.

We have a system that is flexible to adapt to current conditions, we just have to exercise it. Let’s face it, over the last 20 years, we have sold our manufacturing sole to the bad guys. Some how we thought just coming up with the ideas and making money off of them was all we needed to do. Now we find out we are not the only ones with ideas and the bad guys don’t depend on us anymore.

We are kind of funny in that sometimes we operate on the extremes and not in any sort of balanced manner. In our current cycle we seem to be heading from what I would call Brute-Force Capitalism to Socialism. Brute Force Capitalism is when all we care about is the current quarters results no matter what the results will be for the future.

In racing for the profits and not thinking about the future, we have painted ourselves into a corner. We don’t have a manufacturing sector to work our way out of this recession and the other parts of the economy depend on it (ie service, banking, etc.) So what do we do?

The Great Plains

I am born and raised in Nebraska.  I haven’t figured out exactly how the connection forms for some people to a particular geographic area, be it genes, up-bringing or whatever, but I have always felt attached to this area.

I admire it’s people for being hard working and self motivated.  Most people around here would rather “do it themselves” than let the government do it for them.  Yet they will drop everything to help a neighbor in trouble.  Maybe that is why I enjoy Amateur Radio so much.  Our community shares many of those traits.  We like to do it ourselves, and to help others learn to do it also.

It hasn’t always been easy.  Urbanization has taken it’s toll on the Great Plains and sometimes our “work ethic” has been misconstrued as being patsies.  I think the tide may be turning.  I came a-crossed an article on Newsweek about how the Great Plains are weathering the Great Recession.  You can read it here: http://www.newsweek.com/2010/07/02/the-great-great-plains.html.

I know it’s a stretch, but it does kind of parallel the plight of Amateur Radio.

RFI in the Shack

Like all Amateurs, I ran into a problem with RFI in the shack.  I have a 100′ Windom setup that is feed with dual RG6 coax that goes into a MFJ-962D antenna tunner.

For the most part the setup works pretty good.  I have never been able to tune 15m or 160m, but I could the rest of the bands.  I always got a little RFI on 40m, but not so much that I couldn’t work it.

Well something changed over the winter.  I don’t know if it has anything to do with the antenna, or the ham shack.  I just got done rack mounting my main rigs and I suppose that may have changed something.  When I ran psk on 40m and 80m, I would get RFI and the rig would pulsate output so bad it was unusable.

So this weekend, I tried a trick that Woody KCØWA told me about.  I took a 1000pf ceramic capacitor and soldered it from the shielding to the center conductor of an old piece of RG-8 that Gary NØSJM gave me on BOTH ends.  Then I connected one end to the ground in the shack and the other end to the ground rod just outside the shack.

It worked for the most part.  The plusing is gone and I can work 80m again.  On 40m, the pulsing is gone, but I still can’t eliminate the ALC when I try to run PSK.

So I am going to try one other thing over the memorial day weekend.  Then maybe I can be conpetative when the next contest rolls around.

070 Three Day Weekend Contest

Just got done participating in my first contest.  At least the first one that I made a real effort to participate in.  Not sure how well I did, but I did try.

I learned a few things along the way that I will share with you for better or worse the next few days.

First, logging.  From the 070 page I followed the link and downloaded GenLog from W3KM at http://www.qsl.net/w3km/gen_log.htm.  Pretty neat program.  It took me about 10 minutes to figure it out and get started.  I have to say that I am impressed at how he updates it for all of the contests.  I logged the contest and then uploaded the ADIF file to the KJ4IZW  Scoring Tool http://dwestbrook.net/projects/ham/scorer/ to create the file that I emailed in.  Then I imported the ADIF file to hrd and eqsl.  Worked well.

I learned a couple of things about my antenna setup also.  I will share with you what I did to fix the problems as I go along this week.

Pocket Video

I have been looking for a way to record events at our association meetings and while working on projects.  I finally found what I was looking for.  I recently purchased a Creative Labs VADO HD 3G Pocket Video Recorder.

Creative labs description:Creative Labs VADO HD 3G

“See it, shoot it, and share it–all in high definition. Creative Lab’s third generation Vado HD Pocket Video Camera (Black) makes it easier than ever to record outstanding video in 720p high-definition quality. Featuring a new, ultra-stylish design, the Vado HD is slim enough to fit in your pocket, yet its 4 GB memory capacity holds up to 120 minutes of widescreen HD-quality video. With instant one-touch recording and included Vado Central 3.0 software, you’ll be watching, sharing, and editing outstanding video with ease.”

So far so good.  I have taken several videos for this blog and ARAN’s website at http://w0wwv.org and am learning to edit them with Microsoft’s Movie Maker software.  The HD camera included is an added bonus.  I have been using it to document my projects and it works a lot better than my Droids camera.

Computer Viruses and Amateur Radio

Let’s face it, like or not the majority of us depend on our computers in Amateur Radio.  From controlling our Rigs, to logging, to DSP, we couldn’t do a lot of the neat things we do without them.

So if you are using a computer and it is connected to the Internet, we have to deal with Viruses or Malware.  The majority of the infections we see these days are the malware kind.  I am not sure why the distinction was made, but Malware is usually someting that infects your computer when you visit a web page.  We used to joke that if a computer came in with malware on it, the user was visiting too many sites of the kind that they didn’t want there spouse to know about.  We can’t say that anymore.  A lot of the malware we have seen the last 6 months, has come from visiting legit sites.  The web sites are accepting ads from nefarious business people without realizing it.  These ads contain the malware.

So what is the Amateur Radio operator to do to protect his or her computer.  We all know that most of us are working on a tight budget.  We have tried many of the free anti-virus software available and they all seem to work to some degree.  Lately, we have been using Microsoft’s Security Essentials http://www.microsoft.com/security_essentials/.

It is free for personal use, and seems to work well.  It also appears to have less of an effect on the performance of your PC.

If we could just get these people to write good legitimate code for Amateur Radio use instead of this stuff, we wouldn’t need Anti-Virus software.  Until then, you need to be vigilant and keep your Anti-Virus updates current and your OS updates current also.

The Extraordinary History of Amateur Radio Satellites

I stumbled a crossed this page this evening  on Space Today Online.

What an amazing history the Amateur Radio community has with space.  It is incredible what “non-professional” engineers can accomplish.  Maybe we just need to turn over the Manned Space program to the Amateur Radio community.  I have a pretty good feeling they wouldn’t throw away all the accomplishments and sacrifices made by the engineers at NASA over the last 5 decades.  Just Saying….

Team Building

As president of the Amateur Radio Association of Nebraska the responsibility of rebuilding our Severe Weather Spotter Network partially falls on my shoulders.

Like most Amateur Radio groups over the past several years our members have aged and are less inclined to be available for these types of activities.   We have been working on bringing new younger members into the association for the past year, but that takes time.  While we have been successful in getting 5 -10 new licensees, we still don’t have enough to take on all of the Storm Spotting roles.

So I appointed a committee to contact hams in surrounding counties and identify the ones that are willing to help out.  Then the committee will appoint a team leader in each county that will be responsible to coordinate that counties spotters.

We will see how it goes.  If any of you have been through this and have any ideas for us, I would appreciate hearing from you.
