Sometimes I wonder if that’s truly my problem, or if I just have too many irons in the fire.  I don’t LIKE to put things off – it’s just that sometimes I am forced to because something else comes up that has to be dealt with NOW. Then I lose my place and that’s how things go by the wayside for me. Maybe I need to take courses in multi-tasking – do they offer those?  😉

Another thing that I did today (besides finish printing the Skeeter certificates) was to finally do something with my Christmas present.  That’s right – I haven’t written about my Christmas present, have I?

Marianne had no idea what to get me, so I made it simple for her. I made it super simple for her!  I ordered a set of SideKX cover plates for my “portable” KX3, the one I take to work with me everyday, and I had them sent here to the house to her attention. I installed them today (super easy!) and instead of sticking my KX3 inside a ziploc bag inside my LowePro bag, it is now protected by the SideKX.

The KX3 before surgery:

And the KX3 after surgery – now fully protected:

The silkscreening on the SideKX plates is virtually identical to the silkscreening on the original Elecraft side plates.  It would take an expert with a lot keener eye than mine to be able to see any differences.  The price was very reasonale for the extra protection that you get. Of course, I had to put the radio on the air after its operation, just to make sure I didn’t screw anything up.  A couple of quick NAQP contacts on 20 Meters confirmed that I hadn’t!

Oh, one other thing that I got to see today.  At this morning’s VE session that I attended and helped at, fellow Volunteer Examiner Bob KB2VMG brought along his KXPA100 that had just arrived yesterday.  He ordered his as a pre-built unit in June.  I ordered mine as a kit in October.  I was hoping to have mine by the end of January, but if Bob just got his, which he ordered four months earlier than I did, I am now hoping to see mine by Easter.  Anyway, I got to see one live and up close and personal and got to drool for a little while!

QRP – When you care to send the very least!

Tonight I sat down to fiddle with the macros of my Elecraft K3. As I already use M1-M4 for CW memories, I only had the PF1 and PF2 buttons available.

It was the blog post “K-3 Rotating Macros” of W8TN that made me aware of a clever trick for using a macro to reprogram itself. This gives the possibility to have two rather than one function in the PF2 button. My need is for a button that can toggle between the typical pile-up functions Split+1 and Cleanup. In addition I have another macro that toggles speakers on and off.

The two first macros resemble those of W8TN, but are not quite the same:

1. SWT13; taps A>B once to copy VFO A frequency to VFO B
2. SWT13; taps A>B again to copy all other settings to VFO B 
3. FT1; enters Split mode. 
4. UPB4; moves VFO B up according to setting 4, which is 1 kHz
5. RT0; turns RIT off 
6. XT0; turns XIT off 
7. SWT11; taps A/B to go to VFO B
8. BW0045; sets bandwidth B to 0.45 kHz
9. SWT11; taps A/B to go to VFO A
10. MN110; enters Config, Function, Macro
11. SWT12; taps the (2) button to choose Macro 2
12. SWH47; holds the PF2 button to assign it to PF2
13. SWT14; taps the Menu button

Picture of Koss PortaPro from Wikipedia (Malcolm Tyrrell)

Since I often toggle between speakers and my Koss PortaPro headphones (connected to the back of the K3), I liked what I just found on the Elecraft list where the command for speakers on/off was reposted. I have assigned that to the PF1 button which is also the RIT (Receiver Incremental Tuning) reminding me that this affects reception.

Macro 3 is MN097;UP;MN255; meaning:

1. MN097; Access Menu, Speaker+phone
2. UP; Change parameter
3. MN255; Access Menu, Exit

Since the Speaker+phone menu entry only has two states this will toggle speakers on/off.

After the macros have been loaded into the K3 with the K3 Utility Program, the macros are assigned to the PF1 and PF2 buttons by first entering Config, Macro 3, and then hold PF1, and then Config, Macro 1, and then hold PF2.

As you all know, I am a big Elecraft fan. I’ve built and used a K1, a K2, and a K3.  I now own two KX3s. That said, I don’t consider myself to be an Elecraft sycophant.  Heck, I’ll be the first to admit that I did my share of public grousing and fuming back when I was waiting for my beloved KX3 to arrive!  And I am anxiously, but patiently awaiting the arrival of my KXPA100 – this time minus the grousing and fuming. No company is perfect, including the one owned by Eric and Wayne.  They’ve made their share of missteps regarding announced shipping dates of new product. The fact that we Hams are a tough audience at times, also makes things difficult.  They want to satisfy us, and one could be generous and posit that they’ve been guilty of being overly optimistic at times.

However, when it comes to customer service, Elecraft stands head and shoulders among the pack.  Get a load of this sequence of e-mails that appeared on the Elecraft e-mail reflector yesterday. This floored me when I first saw it:

First, from Mitch KD5EYN:

Hi All, 

Love the KX3, and I did not think I had a problem before, but now realize that I do. I increased the height of my dipole and lengthened the feedline to locate the KX3 into my shack. Now the AM broadcast station KOMA 1520 5 miles from my QTH comes through on virtually all bands. I have tried most settings, it is minimal with the preamps all off, but that renders some of the functionality much reduced. A friend has loaned me his IC-756 and it works flawlessly. I realize two different intended radio uses; however the KX3 is my only rig. Therefore I am considering selling it so I can purchase a non-QRP rig to function better for the bulk of my use. 

I have the ATU & battery charger as well as very nice Samsung NiMh cells in the radio. It would come with the PC cable kit and the headphone/mic that was purchased off ebay. I have worked stations all over the world and received great reports. It is just not going to work as my only radio given the RF situation. So if anyone is interested, let me know. Contact me direct through KD5EYN@gmail, I love the SDR and the features as well as the small size. I am not willing on taking a big hit on the sale, but if you want a great radio at a reasonable price, lets talk.

Here is Wayne’s response – one of the owners of the company, mind you!  An owner who actually keeps an eye on, and reads messages posted in just one of the various Elecraft e-mail reflectors.

Mitch,

Sorry to hear about the AM station so close to home. Ouch. 

Two things you may not have tried: (1) RX SHFT = 8.0, and (2) a broadcast-band filter external to the radio. We could easily design a notch filter for you that would take it out. If you’re interested, let me know. (No charge.)

Now in turn, a little bit more detail from Mitch:

Hi Wayne, 


I have tried the shift and it helps a bit, but the signals are still present; with the preamp at 30db the audio is as if I am tuned to the station. On lower preamp settings it sounds a lot like loud static crashes. I finally realized the problem to its fullest extent when I set an AM radio at low volume where I could hear the programming relative to the noise on the KX3 audio – and BINGO. I have considered a filter, and have not completely ruled it out. But without trying one, I don’t know how much it might effect the receive capability. So sure, I’d love to have one to try and will gladly return it if it does not work. Also, I have really enjoyed the dual receive in split operations, and as I understand the shift negates that function at the moment. But I’m sure open to the filter. What more info do you need? Should I submit a support request? 


Thanks, 
Mitch

Answer from Wayne:

Hi Mitch,

We’ll have the filter designed by tomorrow and enroute by Christmas. It’ll actually be a high-pass with a cutoff of 1750 kHz, built into a W2 sensor box.

Oh my!  And for those of you in this hobby long enough, do you remember Heathkit’s famous tag line? “We will not let you fail.”? THIS is that philosophy brought to new heights.  You have to consider that sometimes, when a company makes a mistake, it can be due to unforeseen problems with suppliers, unforeseen problems with other 3rd party vendors, and sometimes problems of their own making. But when an owner of a company can and does make a difference for one of their customers?

Wow, Elecraft, wow!

There aren’t that many modifications that you can do to the Elecraft K3. This is very different from the K2 as in my list I now have 138 different modifications for it. But Elecraft does have a few K3 enhancements and mods on their home page and here are two additional modifications that I have done to my K3.

Plug-in roofing filters on main RX board

The first one is to add a wideband LC-filter (roofing filter). The filter was inspired by ideas from W5DHM with three tuned sections at the IF frequency of 8.215 kHz. It is to the right in the image. It is not the best of filters, and probably compromises performance somewhat, most likely because of its low image rejection 30 kHz away. It has however served me well as a receiver filter for the latest version of K1JT’s software WSJT-X. That software processes a 4 kHz band for both the JT65 and JT9 digital modes, and the LC-filter has demonstrated to me the utility of having a wide roofing filter for reception of those modes. The filter also works well for listening to broadcast AM which was what W5DHM designed it for in the first place.

Back panel of the K3

The second modification allows for a connection to the P3 Panadapter without using the recommended KXV3A Interface. All that is needed for the P3 is simply a minicoax with proper terminations. On the underside of the main PCB it should have a plug that connects to the J66 connector (see page 10 in the KXV3 manual). In the other end it is soldered to a BNC connector on the back of the K3. I put mine in the hole reserved for the REF input, as I don’t have the K3EXREF External Reference Input option. The BNC connector was marked with a label that says “IF out” as seen in the image.

Both of these modifications are temporary, and as a matter of fact the last one was just replaced by a KXV3A after several years of service. I needed the KXV3A for the PR6-10 preamplifier. I also plan some day to replace the wideband LC-filter with either the KFL3A-6K 6 kHz AM/ESSB filter or the KFL3B-FM 13 kHz FM filter.
