Since the birth of our second child, I’ve had to become a little more creative in my approach to operating contests.  There are rare days when both children are in phase with their eating and sleeping needs and we can accomplish some things, and then there are the other days.  With the coincidence of the quadrennial World Radiosport Team Championship (WRTC) and IARU HF World Championship contests this year, I thought I would make a game of trying to contact all 59 of the competitors rather than maximizing contest score.  The motivation for this is that WRTC was in New England this year, which is a stone’s throw away from me and middle-of-the-night operation would yield QSOs with the WRTC stations on 40 and 80.

I did end up working all 59 of the WRTC stations with their distinctive 1×1 callsigns by furiously searching and pouncing on both radios on 40 and 80.  In fact, I worked most of them twice before I finally found K1T.  I’m going to do an analysis of the standings of the teams versus when I worked them to test if any of the teams were better at “marketing” than others.  Should be fun!  Anyhow, all of these operators were really outstanding but a special congratulations to N6MJ and KL9A who seem to have run away with the whole thing operating as K1A.

In the lead up to the contest, I finally managed to get the station fully SO2R (single operator, two radio—essentially the ability to operate interference-free duplex on any pair of HF bands) again.  And, in the process, I have automatic band switching again, so I don’t have to run across the basement to switch antennas.  Thank goodness for small conveniences.

Here’s the mess for low-power (100 watts and less):  KK1L 6×2 switch to connect two radios to any of six antennas, W3NQN single-band 200-watt transmitting filters for each band (10-80 meters shown here since I still don’t have a 160 antenna yet), and the K6KV-K8GU triplexer that allows me to share the feedline to the G3TXQ broadband hexagonal beam with both radios.  All this stuff was homebrewed by me but it is all available in commercial form as well.

I’ve described the W3NQN filters considerably in the past, but the triplexer is new (built in March 2014) and since I’ve had some e-mail traffic from a couple of people who know I built one, I’ll probably write something up on it in the next few weeks.  I mention it here because WRTC is actually one of the events that popularized the use of triplexers, which are downright freaky when you think about plugging two 100-watt class radios into a box that separates/combines the signals.  Electrical engineering for the win on this one.  Anyhow, I based my triplexer off the K6KV QST article from June 2010, finding some beautiful Johnson capacitors in a flea market for $5 each and using leftover toroids from the W3NQN filter project instead of the solenoid coils used by K6KV.  The whole thing set me back about $30 total and it works great with the W3NQN filters, to say the least.

This was the second contest with TRLinux contest software by N6TR and W9CF.  It has some idiosyncrasies, such as the effect of CAPS LOCK on the shortcut keys.  For example, did you know that ALT-r is not the same as ALT-R?  The great thing about it is that TRLinux talks natively with the YCCC SO2R+ box that I use to handle keying and audio switching for both radios.  And, the band data is handled by the YCCC SO2R+ with TRLinux, so I didn’t have to buy a band decoder for the K2.  That whole process of setting up the band decoding was another midnight oil project Friday night before the contest started.  Fun and games.  But, it worked flawlessly.

And my three-year-old son, future SO2R CW operator, rocking the Bencher and Palm paddles…”I’m doin’ lots of Morse code!”

The bugs is among us!

As of Friday, if you aren’t already aware, Rich Fisher KI6SN announced that he is accepting requests for Bee numbers for the Annual Flight of the Bumble Bees. which will occur on Sunday July 27th.  The sign up procedures for both Sprints remain the same as last year – however each Sprint has a different sign up procedure.

To become a Bee, the first thing you have to do is visit http://bit.ly/15aGgN1. Once you’re there, you can see what numbers have been requested and assigned.  When you have in mind the number you would like to be assigned, you send Rich an e-mail with your request and two alternate choices to:  [email protected].

In your e-mail, you send Rich the following information:

Your Callsign
Your First Name
The field location you anticipate to be operating from

Your Top 3 Choices for FOBB Number

Then, go back and check the database after a bit of time, as Rich will not be sending individual confirmation e-mails. I saw my name and number appear just a few hours after I had sent Rich my request.

As I’ve stated before, the procedure for getting a Skeeter number for the NJQRP Skeeter Hunt is a tad different.  Just send an e-mail to [email protected], and I will send you a sequential number in a confirming e-mail.  I just sent out a bunch of Skeeter numbers to people who sent me requests last week while I was on vacation.  If you have sent me a request, and didn’t get a reply or you don’t see your name on the roster, then I apologize.  Send me another e-mail and I’ll get a number out to you, lickety-split.

Both Sprints are on Sundays from 1700 – 2100 UTC and both are designed to get you and your gear out in the fresh air to enjoy the Great Outdoors. Personally, I hope to work you in both events!

The Cooler KX plus heat sink installed

From my previous posts my readers know I am now in the process of delving back into the digi modes with my Elecraft KX3. With the digi mods there are long duty cycles and thus the PA's in rigs sure do get a "hot" workout. In the KX3 if the heat goes to a certain point the power is rolled back to not damage the PA's in the rig. There are other events that can cause the rig to roll back power but operating in the digi modes is sure high on the list. Not wanting to operate on reduced power and not to say bringing the rig to this point really can't be good for it I have a choice operate a lower power or find some way to keep the finals cool. The heat sink on the KX3 is good but not great and therefore a

Cooler KX plus compared to stock

product called Cooler KX comes into the picture. This is a very easy upgrade to the KX3 and has been designed to not take away from the KX3's styling. The company is Canadian and Fred VE7FMN has done a very professional job on adding extra cooling ability to the Elecraft KX3. There are 2 heat sinks that are offered and they are the Cooler KX lite and Cooler KX plus. I ordered the Cooler KX plus and am very happy with my purchase. Once I placed my order Fred was in contact with me via email asking very important and clarifying questions to make sure my installation went without a hitch. The heat sink arrived very well packaged and with all the hardware needed for a trouble free instal. The instructions that came via email from Fred were very well layer out and easy to understand. I am never excited when ever I have to take apart either my Elecraft K3 or KX3 as this is the time things can get damaged. The heat sink upgrade is fairly straight forward and easy to do compared to let say the sub-receiver addition to the K3 now that to me was a nail biter. The heat sink instal involved removing two nut and bolt configuration to release the

Two PA's fastened to heat sink

two PA's from the heat sink and then 2 more screws that secure the heat sink to the radio. It was basically the reverse to instal the new heavy duty heat sink from Fred. If you own an Elecraft KX3 I would recommend this upgrade as no matter what mode you are operating in your PA finals will be cooler and thus a longer life for the KX3.

I’m late in getting this update published.  I was on vacation (staycation at home) as June ended and July began.  This past week was my first week back and I was swamped at work.  But all is on track and I’ve completed at least one QSO each and every day in 2014 and the challenge is well over 50% complete. 

In addition, to keeping my QSO per day streak alive…I’ve also managed to add at least one new DX entity each month in 2014.  June was no exception with the addition of Saint Lucia.   This makes 10 new DX entities added to my log this year. 

As I started with my May update, my progress in the 2014 ARRL Centennial QSO Party continues to progress.   The numbers below are as of mid July.

Centennial Points Score:  9,049

Total QSO’s:  1,539

Rank (All): 1,230

Rank (Colorado): 14th

 

The QSO breakdown for June is as follows:

Mode  Number QSO’s

JT65 20

JT9 32

SSB 538

PSK31 0

MFSK16 0

RTTY 0

2m FM 0

Additional notes of interest:

DX Stations Worked in June – 44

New DX Entities in June – 1

New DX Entities for 2014 – 10

Total QSO’s for June – 590

Total QSO’s for 2014 – 2,234

Total consecutive QSO days – 181

Days left in 2014 – 184

Until next time…

Radio Merit Badge Requirements

I was cleaning up the shack on Friday. Unfortunately, the shack becomes a dumping ground for “stuff” that I think I may need at some point in the future. I have a bag of RS232 serial cables. Probably have at least a dozen. 75 ohm TV coax cable and splitters. POTS (RJ-11) two and four wire extension cords. A collection of Palm Pilots with a multitude of accessories. I don’t think any pf the Palm Pilots work anymore. A vast cornucopia of audio cables and connectors. A box of WiFi routers. Computer keyboards. Etc. Etc.

So, I was cleaning and organizing the “stuff” when I just happen to come across a station calling CQ on 40M. “CQ CQ 40 Meters, CQ Boy Scouts, Boy Scouts, this is KD0VMM”. That definitely got my attention. After a short QSO I figured out that these were Scouts from a camp about an hour north near St. Joseph, MO called Camp Geiger and these Scouts were working on their Radio Merit Badge. I continued to monitor the Scout’s QSOs until I heard a bugle blare in the background. The Merit Badge Counselor got on the air and explained the bugle (which had just blown at the top of the hour) signaled an end to that hour’s Merit Badge class. Additionally, there was another Radio class that was just beginning and the Scouts would be back on the air in about 20 minutes. Sure enough, this was the case and I was able to talk to another Scout. After an email exchange with Bruce, owner of KD0VMM, he explained that another group of Scouts would be back on the air next Thursday and Friday as they were finishing up their requirements for the Radio badge.

How cool having a Scout camp offering the Radio Merit Badge! I attended Scout camp many a summer as well as even being a counselor one year, but the Radio badge was never offered as a merit badge that could be earned. What a great opportunity to introduce Scouts to radio!

After a bit of research, it was interesting to see that back when the badge was created in 1918 it was called the Wireless Merit Badge. Then in 1923, it changed names to the current Radio Merit Badge. Requirements for the badge has evolved over the years… and most recently in 2009.

What I didn’t ask Bruce, KD0VMM, was if the Scouts had the opportunity at camp to earn the Morse Code Interpreter Strip. The Morse Code Strip is a fairly recent edition to Scouts and can be earned by:

Carrying on a five-minute conversation in Morse code at a speed of at least five words per minute.

Copying correctly a two-minute message sent in Morse code at a minimum of five words per minute. Copying means writing the message down as it is received.

Sending a 25-word written document in Morse code at a minimum of five words per minute.

Boy’s Life, the Boy Scouts of America’s monthly periodical, recently put up a web application called the Morse Code Machine. Looks like fun!

… as a final note, don’t forget about the Boy Scout’s Jamboree-On-The-Air (JOTA). This event occurs annually during the third weekend in October.
