Elecraft KX3…stand, CW key and battery charger.

KX3 on the new Nifty stand viewed at same angle as below pic

Last week I ordered a stand for my KX3 radio I had seen it on the Nifty ham radio site. I was there looking at their new KX3 radio guide. I have one of their guides for each of my radios and they are great. If you want to find a "how to" with your radio instead of searching through your manual these Nifty manuals have it all set out at your finger tips. So back to the KX3 stand.....I was surprised to see they were
KX3 on it's own legs
 offering a stand for the KX3. I have found here in the shack that when the radio is supported by it's own legs for me it sits on a funny angle still. The Nifty stand uprights the radio to a very easy to operate position......for me anyway. I have read some postings about this stand with some saying they didn't notice any real difference between the rigs legs and the new stand from Nifty.
  Also a week or so ago my KXPD3 keyer and KXBC3 NiMH battery charger came in. I have not yet had the time to install the KXBC3 charger. I have mounted the Key and it worked great right great out of the box. The key does come with other springs to change
the tension of the key. Up to this point I have not changed the key spring tension it works fine as it is.
My Begali key that I have was (I thought) giving me problems with extra dit's and dah's at times. It became very frustrating and even after adjusting the key as well as cleaning the contacts I would still have the same
New KX3 key
 problem. The Elecraft key was great and no extra code was being sent at all........it did not take me long to figure it out and for you CW buff's out there you may know what I mean when I say.......The Eleraft key was "loose", that is the best way I can describe it and the Begali is more "tight" The contact spacing on the KXPD3 is wider and in the past I would had seen this as sloppy spacing. BUT..it seems this works best for me and my joy with the code has come back. I then took my Begali key and opened up the contact spacing, now it too works fine for me. For some reason it never occured to me to open up the contact spacing on the key. I thought the tighter the contact spacing the better the keying ability....don't ask me where I got that idea!!

Antenna switch

I played in the 80 Meter QRP Foxhunt tonight and was quite successful. I ended up bagging both pelts, but it was a close call.

Jim N0UR in MN was first in the bag and was pretty easy. He was using the “standard” 1 kHz “up” split and it was just a matter of working him.

Ray K9XE in IL was another matter. Ray was loud, but was buried under some even louder local QRN. I wasn’t getting a feel for hearing Ray, no matter how I adjusted the K3. With time running out, I decided to switch on over to the KX3. Both radios are new to me, but over the past few months I have acquainted myself with the KX3 just a bit more.

In a matter of minutes, using the Dual Watch feature, and by adjusting the passband tuning, I was able to isolate Ray’s signal. I was also able to determine his split via Dual Watch, as mentioned before, and nabbed his fur with six minutes to go.

There are various reasons that I prefer the K3 as my main station rig. One of the best features, for me, is the built in antenna switch. I can switch between the vertical and the wires in an instant, and use whichever antenna is best suited for the job.

The KX3 only has the single antenna input. To switch between all my antennas, I will have to acquire a better antenna switch than what I currently have. I am thinking of perhaps a Daiwa or a Diamond. In the past, I had been using a no name, bargain brand switch with my K2. Quite by accident, I had found out that when I removed my Butternut from the antenna switch, and connected the vertical directly, the difference was like night and day. Due to the poor quality of that particular switch, it was as if I had an attenuator in line. Needless to say, that switch got tossed. The remaining one that I am using now, is better quality but only has two positions – I need at least three.

I think a Diamond or Daiwa will do a better job and will allow me to use the KX3 more often from the shack. It’s a great rig for Fox hunting!

Taking stock

“It was the best of times, it was the worst of times ……”

Mr. Dickens could not have written more appropriate words to describe my 2012.  I have never been a big reveler of the New Year holiday; but this year, I am quite eager and pleased to see the ushering in of a new year and with it, new beginnings and new possibilities.

2012 was not all depression, sadness and tears, however.  It did have highlights, particularly with regard to Amateur Radio.  The KX3, which I had so diligently saved up for, and ordered on the first night of availability in December of 2011, arrived at the end of May.  For me, it has lived up to and has exceeded my expectations.  I am quite happy with it and am so glad that it is an available part of the W2LJ “radio stable”.  Quite unexpectedly, a K3/10 joined the ranks as well.  I hadn’t dreamed of or intended purchasing one – but consider this to be my dear Mom’s last gift to me.  It is an amazing radio; and I am so lucky and fortunate to have use of both of these fine pieces of gear.

The inaugural 2012 NJQRP Skeeter Hunt was an integral part of my year.  Once again, so many thanks to George N2APB and Joe N2CX and the entire NJQRP Club for agreeing to sponsor this new operating event.  Also thanks to Bob W3BBO who helped me ruminate and come up with some of the details  for this new outdoor QRP sprint.  I had such an enjoyable time assigning Skeeter numbers, actually operating in the event and then collecting and tabulating and posting the results.  I am so happy that my fellow QRPers seemed to have as good a time as I did, and I eagerly look forward to the 2013 edition of the Skeeter Hunt.

I got two new antennas up in the air this year.  My venerable G5RV finally made way, after a dozen or so years, for the 88’ EDZ antenna.  Later in the year, post-Sandy, the W3EDP went up to join it in the W2LJ antenna garden.  Too small to be a “farm”, the antenna garden consists of the Butternut HF9V and the two aforementioned wires.  I pray these wires will last as long as the G5RV did.  There were plenty of hurricanes and nasty winters and wind storms that the G5RV made it through – may these two new wires be as resilient.

I have to include as one of this year’s highlights, my decision to purchase the PAR END-FEDZ 10/20/40 antenna.  This simple wire is a delight for portable QRP ops. It’s super easy to deploy as a sloper or inverted “L”.  It tunes up with nary a problem and is neatly and easily storable in my “Go Bag”.  I can’t think of any downsides to this antenna. It’s well worth the price and comes along with instructions on wire lengths to cut so that you can use it for other bands, if you so desire.  This antenna, as well as my Buddistick have become my aerials of choice for portable QRP ops.

Due to all the unfortunate events which took place this year, and their aftermath, I was not able to actually get on the air nearly as much as I had intended.  I actually had “a QSO a Day” going until the middle of February, when events started taking unexpected turns. From that point forward, “unexpected” became  the norm for 2012, and as a result, severely curtailed my on-the-air time  My major 2012 New Year’s Resolution, to complete the ARRL’s Diamond DXCC Challenge, didn’t even come close to happening.  So as 2013 arrives, I am going to tempt fate once more, and will try for a QSO a Day in 2013.  I am not so foolhardy as to think I will be able to pull it off, but I will do my best – hence my ever present New Year’s Resolution “To get on the air more”!

In addition to day-to-day operating,  managing the Skeeter Hunt and sending out notices for The Run For The Bacon each month, this blog (which will be entering its 9th year in 2013) has become a huge part of my Amateur Radio experience.  It is a most enjoyable part of Ham Radio for me, and I want to extend my deepest and most sincere thanks to all of you out there who take time out of your busy day to read this and share the Amateur Radio world with me.  You are the best friends a Ham could ask for. You all have helped me to deal with what would have otherwise been a most sorrowful year.  A very Happy, Blessed, Joyous and Prosperous New Year to all of you!

Lastly, I hope you all enjoy Straight Key Night tonight and tomorrow. W2LJ will be hanging out near and at the various QRP “Watering Holes” (I will spot myself on QRPSPOTS, so be sure to look out for me). I will be using my Vibroplex Original as my aging wrists just can’t stand up to a classic straight key any longer. If we have the good fortune to work each other, please excuse my less than stellar “Bug fist”.  I haven’t had much practice lately!

Elecraft KX3 NaP3 Configuration Highlights

In mid November I sold my Kenwood TS-590 to finance the purchase of an Elecraft KX3 and become a full time QRP operator.  One of the advantages of the KX3 is SDR I/Q output, which can be used to drive a panadapter.  After some fidling around, I have a configuration that works with the popular NaP3 software and thought I would share the highlights in hope of saving you some effort.  This is by no means an exhaustive setup and configuration guide for NaP3, but it should be enough to get you started.  Remember you can click on the images to enlarge them.

For this example I have used the integrated sound card in my PC and have not yet put a ground loop isolator inline which are both opportunities for improvement.

 

NaP3 Audio In Advanced Tab

NaP3 Audio In Advanced Tab

We begin by manipulating the input sound card port configuration as shown above.  This will vary somewhat from sound card to sound card, but we want to be sure that we are capturing two channels and that the sampling rate is set at the maximum your card supports, which may take some experimentation and is not necessarily the highest sampling rate shown in the drop down.

 

NaP3 Setup Tab

NaP3 Setup Tab

Here on the setup tab of the NaP3 configuration, we need to select the sound card input we are using and where we would like NaP3 to output decoded audio.  Once again we have the option to manipulate the sampling rate, which as you can see is 48k for my sound card.  In addition, we need to select “Elecraft K3” for the Rig Type and specify our CAT parameters.  I began this adventure trying to use the “Elecraft KX3” Rig Type, but I found it to not work very well.

 

NaP3 IF Tab

NaP3 IF Tab

Here is the “fun” part, at least it was for me until I started banging my head on the desk.  Be sure to set your “Global Offset” to 0 and select “Swap I/Q Channels”.  The “IF Frequency Offsets” is where you will have to spend some time playing.  The method I used was to tune to WWV in CW mode on the KX3 and determine the differential between the frequency displayed on the KX3 and the panadapter display.  I then set the offset to compensate.  To configure the offset for USB and LSB modes, I reduced the offset by the amount equal to my CW sidetone.  This should get you pretty close, but may still require a little tweaking.  Feel free to try my numbers, but I am unsure if they are valid from KX3 to KX3.

If you determine some other method to set the offsets, please let me know as this is the most time consuming portion of the configuration.

When it is all over, this is similar to what you will end up with, a nice broad view of the spectrum centered on your rigs current frequency!

Does the early bird get the DX…it’s said he gets the worm.

Last Friday we had a "situation" at work that had me working until about 3 a.m. and when I got home I was still all pumped from work and was not ready to jump into bed. The thought came to me about getting on the radio and seeing what DX pileups were out there. I had heard of folks getting on in the wee hours of the morning and catching some rare DX. With great expectations  I turned the radio on....10m dead, 15m dead, 17 and 30 same thing!! Alas on 40m my Elecraft P3 showed some faint signals, I spun the dial to the frequency only to find it was some very weak State side stations. Not that there is anything wrong with that but it's kinda a let down when one is anticipating WILD DX!!!

I did not check the propagation that morning so there could had been a storm brewing or maybe everyone but me was in bed sleeping. As I have blogged about in the past I am trying to get my ARRL Diamond Challenge award (and doing it QRP) at this point I am at 81 DXCC contacts. You only have one year to accomplish this goal and it's now almost December!!!  Having said that I am "really" at 95 DXCC's for 2012 according to Club log. The catch is the ARRL for the Diamond award is not counting ALL DXCC on the list. It is a long story but it's just how the ARRL perculates. I was hoping to bring my K2 or my newly acquired KX3 to work as I was wanting to get some operating time in before work. I am usually in around 5:30 in the morning and I have until 7 to make some contacts. With my Saturday mornings performance I am not to sure if bringing  the rig would be a waste of time.....any ideas out there???

Fourth and final KX3 video………

Up and running
I have decided to add an additional page to my blog giving access to the KX3 videos. This way they are available for anyone who is interested. This way you do not have to go and search all through the blog to find them. For that reason the 4th video is not on the front page of my blog but rather on the KX3 video page and you will find the tab at the top of the blog if you wish to go there for a look.

Elecraft KX3 part 3 youtube assembly video

Well the KX3 is almost completed and this is the 3rd of a 4 part assembly video of the radio. In this YouTube video I go over the problems I had with the ATU installation, the roofing filter board issue and the battery holder oops I had and needed to correct before there was damage. The build is almost complete but have a look and either get excited about purchasing one or pick up some pointers before you do  your build.
