New Categories for ARRL VHF Contests

Posted on by

The April 25th issue of Contest Update from the ARRL had this item:

The ARRL Programs and Services Committee has approved a rule change for ARRL VHF+ contests effective beginning in 2013 (not this year) to create a Single-Op FM-only category (100 W max, 50/144/222/440 MHz) and a three-band Single-Op category (100 W PEP on 50 and 144 MHz, 50 W PEP on 432 MHz). These changes will apply to the January, June, and September contests – again, beginning with the 2013 January VHF Sweepstakes.

I am always looking for ways to get more people involved in VHF contests and these two new categories may help. The basic idea is to create categories for simpler stations to participate in the contests without having to be in the same category as The Big Guns.

The World’s First Disposable HT

Posted on by

Baofeng UV-5RA few weeks back, I was wasting time doing important research on the internetz when I came across the Baofeng UV-5R Dualband Handheld Transceiver.  This radio seemed to have a boat load of features but the sale price was $65. So I am thinking to myself, just how good is a $65 radio?

The last time I went out to a nice restaurant, I blew through $65 pretty quickly so this was not going to be a large purchase. In fact, I realized that we now have HT’s priced low enough to be an impulse buy. As one of my ham buds told me, “filling up the gas tank of my truck costs more than this radio!”

So, of course, I soon broke down and ordered one and it showed up on my doorstep a few days later. I’ve been using it off and on for a few weeks now. I’ve also noticed that there is a real buzz on the interwebz about this little radio. There is usual Yahoo Group (baofeng_uv5r) and youtube videos.

Here’s the short story:

While not perfect, for $65, this radio is impressive.

Besides using the radio and receiving good signal reports, I did check the receive sensitivity, transmit power and frequency — all good. There are quite a few reviews out there, so take a look at articles by W0HC, PD0AC and OE1RFC. Also, there have been quite a few reports of quality problems with this radio…probably more defects than equipment from the more established ham equipment vendors. See the Yahoo Group discussion to understand this better.

Similar to other radios from China, this radio has a quirky user interface…not as easy to use as my Yaesu FT-60. This means that the programming software is a necessity to get the radio set up correctly, which is the major downfall of the rig. The free software program is crapware, with many people reporting a variety of problems with installation and operation. I did finally get it to work, but it was very frustrating.

I find myself grabbing this HT when I head out the door and leaving my other radios sitting in the desk charger. Someone pointed out to me that the low price of this radio makes it an easy choice — if it gets dropped, broken, lost or stolen, I am only out a tank of gas. While I am kidding about the “disposable radio” idea, the low cost does affect how I use it.

Part II: Say Goodbye to the BNC

Posted on by

I had previously commented on the how most of the handheld radios are adopting SMA connectors instead of BNC connectors. See Say Goodbye to the BNC. For example, the Yaesu FT-60 uses a female SMA connector for the antenna connection. I’d say this is the standard approach for the amateur radio market.

Female SMA on Yaesu FT-60

A few manufacturers have decided to use the male SMA connector as the antenna connection for their handheld radios. I suspect that these manufacturers are following the lead of commercial manufacturers (e.g., Motorola) who use the male connector.

Male SMA on Wouxun KG-UV2D

Many hams will want to adapt these SMA connectors back to the good old BNC, to connect to existing BNC connectors or HT antennas. I had commented that these adapters are mechanically weak but recently I have come across some more sturdy adapters.

SMA-BNC Adapters

The adapter in the center is the common adapter for cable use but arguably mechanically weak for adapting HT antennas. The adapter on the left adapts BNC antennas to an HT with a male SMA connector. The adapter fits snugly on the top of the HT and provides mechanical support. Similarly, the adapter on the right adapts BNC antennas to an HT with a female SMA connector.

The adapter on the left is available from Import Communications. The other two adapters came from Affordable Radio.

I have just started to use these more capable adapters so I am not sure how reliable they are in regular use. In any case, it makes sense to be careful to minimize the strain on any radio connector.

The Next Step in Electronic Communication

Posted on by

It figures: I just get done blogging about the history of electronic communications and Google takes the topic to the next level. Recognizing the inherent problem of cramming a QWERTY keyboard onto a Smart Phone, Google has gone back to the future by adopting a simple binary input device that uses DOTS and DASHES. That’s right, the new Gmail Tap uses Morse Code.

Google has apparently rediscovered what CW operators knew all along: Morse Code is extremely efficient for text communication.

Go to the Gmail Tap web page to get the full story.

The K0NR History of Electronic Communications

Posted on by

Humans have always had a desire to communicate. They started out just talking to each other but then found that it was really handy to be able to write things down. This caused the invention of the alphabet and the training of English teachers to explain overly-convoluted rules of grammar.

In 1831, Joseph Henry was playing around with electric circuits and came up with the idea of a telegraph. We can imagine a simple system where ON means “time for dinner” and OFF means “not yet”. This wasn’t good enough for Samuel Morse, who invented the Morse Code which could use ON and OFF to represent the entire alphabet. This was the first digital code and was used for important messages such as “Laughing Out Loud”, later abbreviated to LOL. This was basically the same as modern text messaging but you needed a trained telegrapher to do it.

In 1875, an inventor named Bell decided that it would be better if you could just talk over the wires instead of messing around with Morse Code. This will be a recurring theme — whether to talk to other people or just send digital codes. Bell invented this thing called the telephone, which is still used today. Basically, a person could talk into one end of a wire and have his voice pop out of the other end.

Later a guy named Marconi came along with the idea that communication should not depend on wires. For example, it was quite inconvenient to drag a telephone wire behind a ship as it moved across the sea. Unfortunately, Marconi didn’t know how to do voice over the wireless, so he dropped back to using Morse Code. ON and OFF is a much easier way to go. Although there is a persistent rumor that Marconi intentionally used Morse Code to torment future generations of FCC Licensed Amateur Radio Operators, I can find no evidence of this. Some people argue that Nikola Tesla invented wireless but I think he had to be disqualified for overloading and shutting down the Colorado Springs power grid on numerous occasions.

Again, not wanting to be limited by trained telegraphers, voice communication (originally called Amplitude Modulation, but now known as Ancient Modulation) was invented. We are not sure who first came up with Ancient Modulation, but there are a bunch of radio hams on 75 Meters still trying to perfect it.

Somewhere around 1973, Motorola figured out that what the world really wanted was a portable phone that everyone could carry around in their pocket. The first attempt at this was the Motorola DynaTAC, which required an enormous pocket to carry it in. Knowing that customers were not going to enlarge their pockets, various mobile phone manufacturers worked feverishly to reduce the size of these phones.

Unfortunately, the mobile phone manufacturers terribly miscalculated, thinking that people would want to actually talk on these phones. As text messaging was added to these phones, it was discovered that most people, especially those under the age of 30, preferred to send cryptic text messages rather than actually talk to anyone. It was also discovered that all forms of human thought can be captured as 140 character messages. Although it was tempting to apply Morse Code to digital text messaging, it was rejected in favor of the ASCII 8-bit code. Instead of using ON/OFF keying, text messages are normally sent with a tiny keyboard patterned after a full-size typewriter (now obsolete).

P.S. I made up some of this stuff.

Newsflash: Not Everyone Is Going to Be an Expert

Posted on by

You’ve probably run into this situation…some of the more experienced radio amateurs commenting about how so many of the newer hams are incompetent. “Yeah, they’ve dumbed down the FCC exam, so now anyone can get a license. Back when I got my license, I had to copy Morse Code in my head, design a triple-feedback-loop vacuum tube amplifier and recite the Gettysburg address backwards in front of an FCC examiner.”

A while back, I wrote about the time when a newbie on an email list asked a simple electronics question and got this reply: Not to pick on you, but is there any requirement these days to have a basic knowledge of electricity and/or radios to get a ham license?

Often this shows up as an elitist attitude of If you don’t pursue the hobby my way or at my level, then you are doing it wrong.

Since amateur radio consumes most, but not all, of my hobby time, it is easy to lose perspective on this. And, yes, I am sure I have complained about clueless newbies and LID operators from time to time.

It’s interesting to put the shoe on the other foot and think about activities that I pursue with much less time and intensity. In other words, think about activities where I am not that experienced and certainly not an expert.

For example, I enjoy fishing but I am really not that skilled at it. For me, fishing is just an excuse to sit next to a stream and enjoy the scenery. If I catch fish, that is a plus (but I always throw them back in anyway). When I encounter Real Fisherpersons, they are usually friendly and helpful, passing along a few tips on what they using for bait, etc. Sometimes I will encounter That Fly Fishing Guy that looks down his nose at any form of fishing that does not meet his high standard.

I also enjoy photography. I have a decent Canon DSLR camera with a few lenses and I manage to capture some reasonably good photos that way. (This probably has more to do with the quality of the camera than the photographer.) My interest is mostly to capture experiences and events in my life and create photos that I can use in my various writing activities. But I know a number of people that are infinitely more skilled than I am. They are generally very helpful and I usually manage to learn something from them. Come to think of it, I have not encountered very many condescending photographers — most of them have been very helpful. Maybe I have just been lucky.

Although it’s a cliche, Life is Too Short. There are so many things we can choose to do with our time and, really, so little time to do it. People must make choices about how deep they get into any activity, all while balancing family time and demands at work. It shouldn’t surprise us when some people choose to be part-time hams and don’t aspire to be the expert in all things radio.

And the final point is, if you think you have something to offer to the newbies, make sure you come across as helpful and make sure it looks like you are having fun. Being the Old School Grumpus will not attract people to your favorite activity. Having fun and inviting them in will!

Use WPtouch to Create Mobile WordPress Site

Posted on by

I’ve been using WordPress for my weblog for years now and just turned on a mobile version of the blog. The WordPress plugin WPtouch makes this very easy to do. It took about 5 minutes to get it up and running.

The WPtouch plugin automatically detects when the user is browsing  with a smartphone and implements the mobile interface. The user has the option of turning the mobile presentation off.

Highly recommended!

Say Goodbye to the BNC

Posted on by

There was a discussion on Google+ the other day about how a particular handheld transceiver has an SMA connector, instead of the venerable BNC connector. I noted that many of the newer HTs are going with SMA, presumably because of the smaller size. In fact, I started thinking about it…I didn’t think you can buy an HT anymore with a BNC.

I took at look at some of the ham radio dealer websites to see if I was right. These radios all have SMA connectors: Alinco DJ-175T, DJ-C7T, DJ-G7T, DJ-G29T, DJ-V17T, DJ-V57T; ICOM IC-80AD, IC-92AD, IC-T70A, ID-31A: Kenwood TH-D72A, TH-F6A, TH-K20A; Yaesu FT-60R, FT-250R, FT-270R, VX-3R, VX-6R, VX-7R, VX-8R. The Wouxun radios are SMA but with a male connector on the radio (opposite gender compared to the other manufacturers…a topic for another day.)

But I did find three ICOM models that have BNC connectors: IC-V80, IC-V82, IC-U82.

The trend line is clear…the BNC is on the way out for amateur radio handheld transceivers.

Do I care?

Well, yes, I do.

I have a collection of extended length antennas that are much more efficient than the standard dummy load rubber duck. These are great for portable operation, mountaintopping, etc. I have not found very many of these antennas available with SMA connectors. Even if they were available, I am not sure I’d want to attach them to an SMA connector on an HT. For example, a 1/2-wave 2-Meter antenna is about 38 inches long — I am skeptical that an SMA provides enough mechanical strength to support it. Even with a BNC, I have always been very careful to not put too much strain on the connector.

We will have to see where this leads but it seems that the BNC will fade away for amateur use. Most mobile and base rigs use PL-259 and/or N connectors so HTs have been the main application for a BNC.

Goodbye, BNC, I am going to miss you.

73, Bob K0NR

Update on Feb 24: I’ve had several people suggest to me “just use a BNC-to-SMA adapter.” This certainly takes care of making a good electrical connection but mechanically they are generally weak.

This Spewed Out of the Internet #21

Posted on by

There’s lots of information spewing forth from the interwebznet. Here are a few items of interest.

Dan KB6NU has started doing an Extra Class Question of the Day on his blog. I think this is a great idea. I may need to borrow  steal reuse this idea on my blog.

The Fi-Ni Report did their usual outstanding job of educating the ham community, this time via A Short History of QSLing. Just because something is fictional,doesn’t mean that it’s not real.

The ARRL announced that the Logbook of the World is going to support the CQ Awards. This is great news for the ham community. The more awards that are supported, the more usage LoTW will get, making it more useful for additional awards.

Buried in the minutes of the July 2011 ARRL Board of Directors Meeting, the Board “authorizes staff to proceed with planning and negotiating a vendor agreement for a Digital QST edition, to be approved by the CEO, General Counsel and the Administration & Finance Committee.”  So QST will be available in digital format soon.

You know, I think this internetz thing is starting to catch on!

Via The Buro

Posted on by

At our local radio club meeting this week, I did a presentation on amateur radio operating awards. The emphasis was on the most common awards: Worked All States (WAS), Worked All Continents (WAC), DX Century Club (DXCC) and VHF/UHF Century Club (VUCC).

I talked a bit about how to obtain a QSL card for written confirmation of  a radio contact. As I discussed using the QSL Bureau, it became clear that this is the kind of thing that a new ham might not learn on their own. In fact, they might not know this even exists.

The “Buro”, as it is often called on CW, is really two separate systems: The Outgoing QSL Bureau and the Incoming QSL Bureau. To use the Outgoing QSL Bureau, you need to be an ARRL member and send your outgoing cards to ARRL HQ. They are forwarded on from there to the other country and ultimately to the other amateur. See the Outgoing QSL Bureau information on the ARRL web site for the full story.

The Incoming QSL Bureau delivers cards coming in from other countries. This work is handled by various radio clubs, organized by call area. You do not need to be an ARRL member to use the incoming service. You can find the incoming QSL bureau for your call area here on the ARRL web site. My callsign is KØNR, so I use the WØ QSL Bureau which has this web site: http://www.zeroburo.org/  The  WØ QSL Bureau is operated by the Mississippi Valley DX/Contest Club. Thanks, Guys!

Now here is the important part:

If you have worked any DX stations, you may have QSL cards waiting for you at the buro. You should supply your QSL bureau a Self-Addressed Stamped Envelope, which they will use to send you any cards that are waiting.

Look up your Incoming QSL Bureau and follow their specific instructions concerning supplying them with envelopes.

Buy the Drop-In Charger

Posted on by

I’d like to pass along a tip that has taken me about 25 years of ham radio experience to figure out. I’ve owned many different models of handheld FM transceivers through the years and have always just used the standard “wall wart” charger to charge the batteries.

Recently, I decided to “splurge” and get desktop chargers for the pair of FT-60’s that inhabit our two-ham household. I never realized how handy the drop-in style charger could be until I had one…the HT is always sitting there ready to go. Most of these drop-in chargers are rapid chargers that sense the battery condition — charging them quickly but also dropping back to a trickle charge once they are full.

Since then, I’ve made it a point to always pick up a desktop charger with a new HT. Yes, it does cost $60 to 75 extra but it is well worth the convenience.

More Summits On The Air (SOTA) Info

Posted on by

I recently wrote about the Summits On The Air (SOTA) program gaining traction here in Colorado. Catching up on some of my podcast listening, I came across Jerry KD0BIK’s Practical Amateur Radio Podcast (PARP) on the topic of SOTA. It turns out that Jerry has gotten hooked on the SOTA program and has been out activating some of the Colorado peaks in December.

Operating a ham radio on top of a mountain during winter may seem like the act of a person with only one oar in the water (or shall we say one half of a dipole in the air?). But actually, we’ve had quite a few days of favorable weather that have been begging us to get outdoors in December. Still, I am on guard for an activation by Jerry in the middle of a blizzard, as he seems a bit smitten by this SOTA thing.

Episode 49 of PARP introduces the SOTA concept near the end of the episode, which is followed by a deeper SOTA discussion in Episode 50. These two episodes run about 25 minutes each, so take some time out to give them a listen.

Mixed Signals from Yaesu

Posted on by

This just in from the Things That Make You Go Hmmm Department: the amateur radio portion of Yaesu splits from Mother Motorola while the land mobile portion stays. This is right on top of an announcement that Yaesu will pursue a digital amateur radio offering based on land mobile technology (i.e., definitely not D-STAR).

The K0KDS blog has a post about the split, so go there for the full story. The ARRL has this news item about the organizational change. Here’s the paper that Yaesu published about their move into digital technology for amateur radio.

Don’t Get Stuck On 2 Meters

Posted on by

When I first got started in amateur radio (many years ago), one of the engineers that I was working with at a summer job told me “Don’t get stuck on 2 Meter FM”. At the time I was a college student and felt lucky enough to have 1) found time to pass my Novice exam, including Morse Code test, 2) found time to travel 150 miles to the regional FCC office and pass my Technician exam, and 3) scraped up enough money to buy a basic 2 Meter FM mobile rig. I was in Technician ham heaven, playing around on 2 Meter FM, both simplex and repeaters. Oh, and we had this cool thing called autopatch that let you make actual phone calls from your car. I really wasn’t worried about getting “stuck on two”.

Even though my discussions with this Old Fart Experienced Radio Amateur revealed that he didn’t see 2 Meter FM as Real Ham Radio, I could see that he had a point. Two meter FM is only small part of the ham radio universe and it would be easy to just hang out there and miss out on a lot of other things. I was reminded of this recently by K3NG’s post: Things I Wish I Knew When I Was A Young Radio Artisan. I agree with most of his comments with the exception of this one:

Don’t get your start on 2 meter repeaters.

This took me back to the comments from the Experienced Radio Amateur from years ago. I get the point — starting out on 2 Meter FM and Repeaters can give you a limited view of ham radio — but I see it as the perfect platform for getting started. Here’s what is working in my area with new Techs: get them started with a dualband FM rig (usually an HT) so they have some on-the-air success. This also puts them in touch with the local ham community, where we not-so-subtlely expose them to other bands, modes and activities. They hear the other guys talking on the repeater about working DX on 10 Meters and start thinking about how to pursue that as a Tech. From there, it just expands out to all kinds of bands and modes.

Just for the record, I guess I did follow the advice of the Experienced Radio Amateur and managed to not “get stuck on two” (i.e., I’ve worked all of the bands from 80M to 10 GHz, earning WAS, WAC, DXCC and VUCC.)

ARRL 10 Meter Contest

Posted on by

Usually I don’t focus on the ARRL 10 Meter contest, especially when the solar activity has been so low. However, band conditions have really picked up and 10 Meters is alive and kicking. We have quite a few new Technicians that are discovering the wonder of worldwide HF propagation with even a modest station.

I decided to operate from our cabin up in the mountains. I haven’t been happy with the performance of my trap dipole on 10 Meters, so I wanted to try something different. I pulled a twinlead J-pole antenna out of the basement and strung it up in a tall pine tree. This basically gave me a 1/2-wave vertical on 10 Meters and I was pleased with the performance.

I had a great time with the 10 Meter contest, operating for part of Saturday and Sunday.

You’ve got to like a contest that has:
– Only one band, so no fretting about which bands to focus on
– CW or SSB, take your pick or do both
– Lots of DX
– Work anybody anywhere
– You can sleep at night and not miss anything

I mostly searched and pounced around but did manage a few runs with my mighty wire antenna. Not being a real CW operator, I did decide that I would push myself to make 10 CW contacts. Most of those guys are going way too fast for me, but I got it done.

Summits On the Air Taking Off in Colorado

Posted on by

The Summits On The Air (SOTA) program was launched in Europe in 2002 but is just now making its way to the United States. Recently, there has been a surge of activity in Colorado as the program gains traction here.

The basic concept of SOTA is an award program that rewards the radio operators that activate summits and the radio operators that chase summits. For those of us that enjoy the mountains and enjoy ham radio, this is a great fit. I won’t go into all of the rules here (Warning: There Are Lots of Them), so check out the SOTA web site for the complete details.

Steve WG0AT (World Famous Alpha Goat) just published another one of his Rooster and Peanut videos that capture his recent activation of Mount Herman. I managed to work Steve on 2 Meters and I make a cameo appearance in his video below as I make my first official SOTA contact.

Steve has been activating SOTA summits for a while now and others are joining in. Here’s a video from Pikes Peak with Mike, KD9KC and Ron,WT5RZ on North American Summits On the Air weekend.

Recently, Jerry KD0BIK succumbed to the SOTA addiction, activating Mount Herman and  Green Mountain (click on the mountain names to see his blog postings). Chris NW5W has also been active…check out his web site here.

There are numerous SOTA videos on youtube from all over the world.

The SOTAWatch web site is dedicated to posting future SOTA operating plans (Alerts) and SOTA activations in progress (Spots). The North American SOTA Yahoo! Group is another great source of information.

See you on a summit soon.

A Pretty Good List From K3NG

Posted on by

K3NG reposted one of his classic articles Things I Wish I Knew When I Was A Young Radio Artisan. Here’s a few items from the list:

With antennas, it’s not about the feet and inches (or meters), think in terms of wavelength.

Don’t worry about the orientation of a dipole when it’s less than a half wavelength above ground.

When the bands are open any goofy antenna will make contacts. People will think this makes a goofy little antenna a good antenna. Not so.

I don’t agree with everything on the list but it is still worth reading.
