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.

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.

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!

ARRL Field Day is the single most popular on-the-air event held annually in the US and Canada.  Each year over 35,000 amateurs gather with their clubs, friends or simply by themselves to operate.

The information packet for Field Day is now available on the ARRL web site.

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.

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.

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.
