Ham’s of last Monday

Ad some of you know I am a editor for my clubs newsletter called Short Skip, every month I go through my rss reader and find content to publish with in the newsletter, I then email the person and ask permission to publish the blog post.

I came across a cross post from another ham KH6JRM who writes comments about other websites via Scoop.it onto his website (thinking about doing tht my self). Russ posted a website/article about another Tom Carter W3ATB who just  happened to be working communications at the marathon in Boston, Mass where the tragic event of last sunday happened.

Have a read of his story of what happened in his eyes

New Project: Homebrew Communications Speaker

mobile speakerAfter installing my Kenwood TM-G707A into my 2010 Chevy Malibu, which BTW I need to post pictures and or video of (Please remind me), which brings me without a speaker in the shack. The speaker I had in here was a Generic version of the MFJ Clear Tone 4″ speaker, It isn’t all that bad of a speaker when on SSB but FM well? It has a little to much bass when the volume is low and I couldn’t stand to hear the tinniness when checking people into the local club net. Now that I am able to go stroke M, I needed a speaker in the car, so in it went! You know its sad, I couldn’t place the speaker where I wanted it. The Malibu has about six inches of useful space to the left of the break peddle, but the Velcro glue/sticky part wouldn’t stick to the plastic! Anyway I was able to put the speaker under the drivers seat thanks to an add on feature! Able to remove the side panels of the center console, I  run the cord go threw the console.

Back to the home QTH, I am missing a speaker, I grabbed a center speaker from an old entertainment system that went bad about 2 years ago and I tell you what, it sounds AWESOME… But I don’t like the way it looks, its in the way, and the wrong impedance. So my project is to build a communications speaker for ham radio!
First thing anyone should do before any project is research,  most of  my research was either a no brainier or had already been known.  Building the box is about the easiest part if the research MDF,  glue, screws, and pillow stuffing. The speaker is one that needed to be researched a lot to find out what brand and kind of speaker one needs buy, for it to sound good.
First thing, you need to find out is how many Ohm’s your radios output is? 4 or 8 Ohm? Most amateur radios play in 8, but have been known to use the later.

OK so what is with the 4 and 8? 4 ohm speakers are generally louder due to the fact an audio amplifier can supply more power to an 4 Ohm load than to an 8 Ohm load. 4 Ohm speakers are used in automobile audio systems because the stereo systems used in cars operate more efficiently when mated with lower-resistance speakers. 8 Ohm speakers are used in high-end home audio applications where amplifiers tend to be more powerful and designed to operate under a heavier load.

Beware of the impedance range of the amplifier. Using 4 ohm speakers with an amplifier designed for 8 Ohm loads will damage the speakers and the amplifier. Although you can use different Ohms just note an amplifier’s power output will be reduced and will sound low. After all that confusing mumbo jumbo I choose 8 ohms for this project, next was the size.

31sWD0jWopLSize in this case doesn’t matter,  but you do need to figure out where your going to put the box and will it fit. I choose  the Visaton FRS8-8 3.3″ Full-Range Speaker because it is the right size for where I want to put it. Along with size, Wattage becomes a big factor. Most communication speakers one buys from a hamfest or online are between 5-20 watts and rely on the amplifier in a radio for oomph and volume. The speaker I choose is rated for 30 watts which has plenty of leftover juice, that’s if I was wanting to add an Amp.

Now here is the kicker Frequency range. All of the external speakers, hell even the internal speakers start with a low frequency range of around 200 Hz to around 500 Hz. The top end can go upwards of 20,000 Hz which BTW is the maximum freq range of most if not all speakers on the market. The FRS8-8 is from 200 to 20,000 Hz which is nice because I didn’t want everything on the low end cut off. I’ve read other speakers builders who have built such speakers for our little hobby, like to have a speaker range of 325 Hz to 6000 Hz.

So this is the project I will be looking forward to working on in the weeks to come,  mind you it all depends on how the fast shipping is (Happy smile). on the way home from work I stopped off at Lowes and picked up a 5/8 12×8 piece of particle board for around $5, it should work great for my speaker, I just need to figure out what I’m going to use to make it look perdy on the outside!

Paper Logging

Aha paper logging, some people may say why? Well I think its a cool thing to have hard evidence that one has had worked a particular station.  I get the butterfly feeling in the pit of my stomach and since of pride when looking at my logs.

The ARRL has a very nice paper log sheet that one could print out, but I have found that its a bit out dated. The way I store and write my logs makes it a bit cumbersome. I keep my logs in the side pocket of a binder, finding a particular date means I would have to pull all of them out and search for the date and time.
Things that are a bit out dated is “QSL Sent”. Due to the fact that a lot of people use LOTW and most (including myself) upload logs after a week of making a contact it needs to go. The Comments section also needed to be updated, separating QTH, NAME, and QSL VIA into their own columns would do them better justice.
So what can I do to help? I created my own Log sheet.

logSo what did I do to make a better log sheet?  On the ARRL log Sheet it as a FREQ column, most people doesn’t write the frequencies into this box but instead write the band, why not change it? Like I said before, QTH and Name now have its own column and so does QSL VIA. New hams have asked what does one to put in that place, well lets say if a special event station wanted one to send a QSL via a manager, his home call, Logging service, or Direct this is where one would put it.
LOTW, eQSL, and Paper was added for those who like keeping a record if someone has confirmed a QSO on one of these services. Time (UTC) Finish has been moved closer to the end for better record keeping and a date portion is added to the end of the sheet so one could write a date vertically such as January 13 – February 20, 2013, this is to be seen when searching for a particular dated log.

R&L Electronics Giveaways

I was browsing some of my ham blogs and this popped up on my radar.
Starting March 4th R&L Electronics will be giving away 1 (One) radio a week for 12 (Twelve) weeks.
4 Yaesu FT-60R’s, 4 Kenwood TM281A’s, 4 Alinco DJC7T’s will be given away, all would be a great to own… except the under powered Alinco HT but that’s just my opinion.
Anyway check out http://www.randl.com/shop/catalog/radioweekprev.php for more details

My Ham Projects

Since becoming an amateur radio operator I have been working on some personal projects of my own, these projects are very dear to my heart because we don’t have anything like it, or anyone doing such a thing.

The first thing I did when I got my ticket is build a list of hamfests for the chicagoland area. The ARRL doesn’t do a good job at updating the list and its not their fault, some clubs just don’t submit the hamfest listing due to ignorance of all types.
The ARRL could take the time and research the previous years hamfest listings and see if the people who are putting it on are still doing a fest that year. But its all about people donating time or paying someone to do it. So what did I do about it? Well I created a spreadsheet that lists every hamfest within 100+ miles of the chicagoland area and its updated every month - tinyurl.com/chihamfests

Next I got frustrated at was the lack of finding things to do on ham radio, listening is all ok, but you need to get rid of the mike fright if you’re a noob and that brings me to nets. When I started creating the long lists of nets, all I could find was outdated lists that weren’t in a open source format that would let one update if the net went off the air or something had changed.
So this was project two a list of 62 nets in the chicagoland area - tinyurl.com/chicago-ham-nets

Work and no play

I would like to blog more , but work has been keeping me busier than I would like, So I’m going to try and update, what I can.
I dont know if I posted on this blog that I became Secretary for my local amateur radio club YAY huh? So far I think its going to be pretty cool, I’ve been going to the board meetings for the last 8 months and filling in when needed, so being inducted into a position is not that much of a shift from just sitting in the background to doing something. I’ve also been doing a net on the clubs repeater(s) for the last 5 months, I’ll have to sit down and write out a post just on how I do a net, I might also to a companion post about types of nets.
I’ve been working on a new DIY project, creating a interface between my 10 meter rig and computer, wanna play some RTTY and PSK.  I ordered the parts from china VIA eBay and have to say you can get some stuff alot cheaper and faster if you just run down to your local Radio Shack. Whats cheaper? Well 1:1 transformers and project boxes, both have about a $2-10 difference. Any way Just before the new year I ordered 9 items and like most of my projects I missed some! The first arrived Tuesday which was kinda surprising because it was the heaviest of the 9 (1K Pots 10 in total). The next thing to arrive was the PCB(the mail lady almost forgot to put in the box). I have to say I was not satisfied with the PCB. I ordered 10, 5 by 7 cm boards and they arrived sticky! I mean so sticky I had to take rubbing alcohol to them to clean them off OUCH! (This note is to remind me not to use rubbing alcohol near or put on my/your desk (it strips the finnish off)  trust me don’t do it, oh and the next desk, make it out of a laminate countertop). Well I cant wait till the rest of  my order shows up, I still have to buy a few things(from RS), project box , 1:1 transformer and other things I may have missed… OH damn, forgot to get kobs!

Ham Years Resolutions – 2013

ny1With the new year upon us, what are your 2013 new years amateur radio resolutions?
As we all do every year, we try and make and keep personal resolutions. One of mine from last year was to quit smoking. As of this writing it will be 3 weeks and counting.
For 2013 I want to do something a little different, I want to set me resolutions around the greatest hobby I have ever had.

  • Upgrade straight to extra. This won’t require much, just some studying time. I was hoping to achieve my General by the end of 2012, but no such luck!
  • Learn CW, its alway been hard on me to learn a new language, I’ve learned a few snippets of code, its just getting the brain to fire the right nerves to learn the rest.
  • Attend a Field Day, missed the last one due to having other obligations, and from working a few contests I can see the hype surrounding field day.
  • Achieve an award. My DXCC might be the one I achieve by the end of next year, achieving an award as a no code tech is kinda hard, and with only 10 and a solar cycle that wants to be a pain in the caboose doesn’t help.
  • More antennas in the air. With fingers crossed, I am hoping to purchase a new home, and better air time.
  • Do more DIY. So looks like a two for one, build things, and have patience in troubleshooting.

So that’s what I’ve come up with for now. Have a good holiday and new year everyone!

2012 ARRL 10 Meter Contest – DONE

YAY! what a fun but long weekend? I just got done working the 10 meter contest and submitted my logs, first to LoTW which I bet will bounce up to 15-20 days of back logs. The other was a bit more challenging because I had never submitted a contest log before, only took about a half hour to figure out.

The propagation was in the Guano, at least I had a laugh at CA, huh looking at the DX maps for the first 24 it was dead for CA, I never heard a peep from 6 land till the last 8 hours which is kinda surprising. Anyway I made 55 QSO’s with 26 multipliers adding up to 1430! From what I was told my score is BAD but so is everyone else’s.

I got 10 new states for my WAS including IL @ 68.3 miles away! To bad my contact within IN was only 36 miles… Adding to my growing list of DXCC entries is 4 new listings, Canary Islands (Sexy sounding XYL Operator), Nicaragua, British Virgin Islands,  and Curacao.

Now its time to think on how to improve my antennas and setup for the next content.

New in the Shack

New to my shack  (but have had for a long time) is my SCP SC-40-AS Comm Switch, its a 4 position switch that allows me to switch between 3 antennas, Don KA9QJG  gave me 25 ft of Radio shack RG 8x/U (the heavy duty kind) which allowed me to bring both 10 meter antennas into the shack.
I got done with the project a hour into the 10 meter contest, Don was telling me that he was hearing LA (a state I didnt have but now do) and I was screaming back “Will you please let me finish soldering the the coax (you know its kinda hard to solder and PTT).

Then I ran into a problem the jumper I was going to use broke inside the PL-259. No problem I thought I’ll cut it and solder a new one right on there… Done, plugged in the old end to the switch and it too broke…  now I’m pissed and out of PL-259′s… JUST GREAT, time to use my other jumper, it works but has loose connection on the SO-239 of my Rci-2950… Damn those cheap truck stop jumpers! Oh well I had to use it until Monday when my suppler opens for business.  :-D

Anyway I had to prop the switch because of the heavy coax, so I put my Superstar 4900+ (worthless POS) on top of my RCI-2950 which made the switch snug.

Also if you noticed the red fan on the left of the image its for the rag chewing I do,
don’t want to burn out the Kenwood during a net or qso.

Why is it so hard?

I was talking with my good friend Don KA9QJG and he related a story about his grandson not wanting to become friends with a “Geek” who was interested in Amateur Radio. Don put to question why aren’t kids interested in amateur radio and what should we do to get them interested in amateur radio?

Well you have to think of our history of amateur radio. It has pioneered a large part of our technology we take for granted. TV, broadcast radio, mp3 players, and cell phones, hams at one point in its development have had a part in the internal working of these devices. But, if you look at the technology that ham radio has to offer today, its kinda lacking on the “TECH” and “WOW” factors that have gone to the way side.

I do realize that as we are getting up in age, things that interested our generation are not grabbing the interest of the current generation. Being young enough and being a kid at heart, I tend to have this over thinking problem that has gotten me into trouble from time to time (as a 3 time drivers test applicant I can’t argue) and I do like to think outside the box, which gives me this alternate way of thinking. Our current generation doesn’t get that same thrill we got when we made our first contact! Why? Well,in big part it’s the internet. It’s spoiled things to no end. Why try and make friends with your voice, radio, and a long wire, when you can jump on the computer and log into a chat room and talk to anyone across the world, or go to a site like Stickam.com and have a live webcam session with 3-5 people and be able to see them.

So what should we do to get them in the game?

Well some kids are just lazy. Yes that is blunt but it is the truth. On occasion you sometimes get the right kid that have the energetic thrill to learn. I started talking with my 7 year old nephew about amateur radio and he thought it was so neat that I could talk to people I have never met over a wireless radio. I let him play with my HT, powering it off and on and allowed him to push the PTT and toss out my callsign, unfortunatly, most of the repeaters in that area are dead and or deaf to a HT, but he still he thought it was neat. Then I got him into electronics. This is where he gets the biggest kick. Building an electronic device that does something is the coolest thing you could ever give a 7 year old.

I want to ask you a question? When you were his age what were you doing? Most likely building things, or in my case I was building forts and disassembling electronic device (Yes I found out what stretch armstrong was made out of!).
Getting them hooked and stayed hooked young before their mind wanders off too far toward the other new technology should be your first priority.

A young kid might get a kick out of talking to Santa over the radio. Each year, on 14300 khz, a regular puts on what is known as a “Santa Claus Net” bringing a volunteer Santa into his or her ham shack and sometimes lady operators will play Mrs. Claus. This a great way to introduce grandchildren to ham radio when visiting over the holidays. Explain how radio waves propagate on hf and tune to the twenty meter band to find Santa ready and waiting to hear from the kids. Here is the website for more info: http://14300.net/santainfo.htm

Now you might ask what if it’s too late? Well, if he/she doesn’t get that thrill of the first contact, I would suggest contests or awards. The ARRL has a ton of them and those are just weekend contests. Awards can be fun also (WAS, DXCC, and band only awards). Try getting your WAS or DXCC with only 10 meters! (its fun but here in Indiana its difficult if all your WAS contacts are the west coast). There is also all the digital things we do with computers: JT65, RTTY, SSTV, Dstar, etc. Other things we can do is have events with a GOTA (Get on the air) station, invite the local schools to come out the event and ask them to announce this event, talk to your school about bringing in vintage equipment and show how hams and shortwave listeners in midst of WWII would listen to the radio reports coming in from overseas and would send reports to the families of soldiers in POW camps. Storm chasers and Skywarn spotters can participate by showing and teaching kids about storms, equipment used in reporting, spotting and even chasing storms. At hamfests kids enter free if shown a school ID, donating the ARRL Handbook or licensing materials to a school or library with a note written inside the cover about where they can go to get tested when finished. And of course contacts to the ISS (International space station)! Fun for kids and adults! Who wouldn’t want to talk to an astronaut?

At 11-17 it gets harder to peak interest. Other factors come into the equation for both boys and girls. The opposite sex is a big distraction to contend with. Keeping them hooked also falls into this category. Its a hard thing to do although some people will tell you once they get a taste of the ham they never forget and that is true it follows later in life.

I don’t like saying this because some may take this the wrong way but its our fault! Society has taught our kids to not talk to strangers and this has made it harder for elmers next door or down the street to teach kids about amateur radio. Making it even more blunt, we have become dirty old men in society’s eyes, well maybe just Don KA9QJG. Think back when your elmer used to teach you about amateur radio and then look at today. How are you going to pass your knowledge on? Its kinda hard and a little of a let down. People have already started moving past this problem by moving onto the internet, with newsgroups and websites

I’m not a psychologist and I don’t play one on tv. We as teachers have a lot of distractions to contend with including Barney the purple dinosaur and Spongebob. All I can say get them hooked young and keep them hooked.

I would like to thank all the people that helped me think of ideas for this article, you guys are the best: Dennis W9FBM, Ron K9JON, Steve KC9MQI, Lou KB9IPT, Mike WU9D, Kerry KB9ORH, Bill N9OTP, Henry KA9GKT, Paul KC9UVT, and Don KA9QJG.
