10m wide open!
Ten metres has been wide open today. Stations have been heard or worked in just about all directions. I ran 2 watts of WSPR during the periods that I wasn’t in the shack and the program screen resembled 30m!

| WSPR spots on 10m at G4ILO, 26/9/2012 |
After a short period of WSPR I switched to voice mode and made a nice SSB contact with Ken, JA2FJP near Nagoya (nothing to do with cheap Chinese antennas!) After a rubber-stamp contact with R100BG I found phone a bit hard going with all the QRM and pileups so I retreated to the more restful pastime of working digimodes.

I made one more Japanese contact – with JI4POR – and made my first-ever China contact – with BG8GAM – all on PSK31. I heard several more stations from those countries and also one from Korea (South, presumably) and one from Indonesia but didn’t manage to work them. Better luck next time!
A session of calling CQ produced an endless succession of Russian stations. Where do they all come from? There is no chance of working interesting DX unless you search and pounce on the DX stations. Even when calling a specific DX station I was being called by Russian stations! Why do they do it? I lost the chance of a couple of first contacts because of it.
As the afternoon wore on many stations from North America and Canada started to be in evidence. My final PSK31 contact for the day was with Bob KZ0G in Missouri which is probably a first for that state for me.
Not a bad haul for a few hours listening / operating using a maximum of 40 watts PSK31 to an attic dipole. I wish there were more days like that!
PSK31 to Amman, Jordan
Conditions have been good recently on 15m. On that band I have a choice of two antennas – the multiband dipole or the magnetic loop. The multiband dipole doesn’t actually have elements for 15m so on that band I think the 40m element must do the work. The K3 ATU is needed to produce a good match.
There is quite a big difference in performance between the two antennas on 15m. The magnetic loop, surprisingly, has a higher noise level but it also produces stronger signals on some stations. On other stations the dipole seems best. It’s a pity I don’t have a sub-receiver in the K3. It would be interesting to try diversity reception one day.

| Amman, Jordan |
Whenever a band is open you can usually find some PSK31 activity even if you can’t hear any phone. That was the case yesterday on 15 metres when I worked Nart, JY5IB from Amman, Jordan. That’s an all-time new country for me so I was very pleased to get him into the log. On this occasion it was the magnetic loop that did the job.
Where did I find those other 60 hours a week?
So I finally pulled the plug on the day job six weeks ago. For the first time since I was 18 years old, I don’t have a regular pay check coming in. Unless you count that Social Security thing, which is hardly enough to call a “paycheck.” I had big plans for all the new spare time I was going to have in retirement, including actually getting on the air more, seeking out long, rambling ragchews, working more PSK31 and RTTY, doing some QRP, maybe even building a kit or two and trying out an antenna idea I’ve been contemplating. Contemplating for a dozen years.
Truth is, I only retired from one of my several jobs. For some reason, I quit the only one that actually paid me a regular wage, which automatically brings my sanity into question. But like a gas occupying a vacuum, the other things I do quickly expanded to take up all my available time, including what the day job once took. I have no idea how I was able to work those sixty hours a week at the old vocation!
Some of you may be aware that I am a writer, too, and just published my 24th book. I’ve also finally gotten around to putting one of my novels–my second book, published way back in 1997–up on Amazon.com as an eBook. (I hope it finds a bigger audience this time because it is near to my heart, the story of a young man who falls in love with the magic of radio, goes on to a career in broadcasting as a deejay, and eventually his best friend, who just happens to be a ham, saves his bacon…using a trick many of you will recognize. It’s titled WIZARD OF THE WIND and, yes, there is a lot of me in that story!)
I’m also finishing up an amateur radio book, one that has been in the works for a while, too. It will include some of the articles and short stories I’ve put up on eHam.net and more. I want it to not only entice those who develop an interest in ham radio to go ahead and take the plunge but to also encourage those already in the hobby to explore other aspects and become true evangelists for it.
When I was writing WIZARD OF THE WIND, I actually took a weekend job at an oldies radio station for a year, working a weekend deejay shift, just to get that old feeling back. It really helped me put it into words as I worked on the novel. Maybe now is the time that I should be getting on the ham bands more, broadening my own horizons so I can capture the magic of the hobby as I work on the new book.
I think I just talked myself into getting off this blog and seeing what the DX clusters are saying. Or watching the waterfall for a bit on 20M PSK31. Time’s wasting!

Please download and enjoy. It’s at the Google Play marketplace, as well as via the Black Sparrow Media website, and it’s still free!
- The LHS Hamvention fund drive was a success! LHS will be at Dayton Hamvention 2012, May 18-20, in the North Hall of the Hara Arena in booth 131, the same place as last year.
- Russ fixed a website bug that may have been causing some visitors to see the Black Sparrow Media site when surfing to LHS. Thanks to John, EI7IG, for pointing it out.
- Please sign up for the LHS mailing list at http://lists.blacksparrowmedia.net/mailman/listinfo.
- Please join the LHS subreddit and contribute show topic ideas, news of interest to our listeners, or just about anything else.
- Please tell your friends about the show.
Topics:
- Stan Horzepa, WA1LOU, in his recent Surfin’ column on the ARRL website, recommends open source Apache OpenOffice and the desktop publishing software Scribus. Note, LibreOffice is a fork of OpenOffice and is also quite functional. Both offer word processing, spreadsheets, database and presentations. Scribus may have a steep learning curve, but it’s a very powerful program. Easy tasks are easy to accomplish. Complex projects may take more effort to learn. Also note that many open source programs, like OpenOffice, Libre Office and Scribus, are available for Windows, OS X, as well as Linux.
- Take a look at the ham radio section at Linux Journal which also has links to their Ham Shack forum.
- Richard discovered several open source ham radio applications at Sourceforge: ircDDB_gateway, CQiNET, phppredict, contest loggers, fldigi, paclink-unix, OpenMOR, software for SDR radios, Ham Radio Net Logger, and more. So, don’t just look in your distributions repositories for applications. You may have to compile the programs from SourceForge yourself, but it may be worth the trouble.
- Finally, a reminder to visit KE2YK’s Random Oscillations website.

LHS Episode #082: Hamroids
In a world first, or maybe just podcast first, the guys throw caution to the wind and actually product an episode with some real Linux and ham radio content. We know it’s shocking, but sometimes–just sometimes–a miracle happens and you get the belly laughs along with something to stimulate your gray matter. We can’t promise this will happen in the future, but this time you’re safe.
On the Linux side, Richard found an article on the ARRL Web site which leads to a discussion of OpenOffice (Libre Office) and Scribus, two excellent document preparation suites. On the ham radio side, Russ discusses some useful Android applications which might be helpful to those operators who want to use their devices for logging, CW training, PSK31 digital mode communications and more.
Thank you for all the donations to the Hamvention fund. Russ hopes to see as many folks as possible during his time at the show. LHS will be in the North Hall, booth 131.

More KX3, iPad and PSK-31 Experimentation
Last week I created a YouTube video to document some experimentation I had completed with the KX3, my iPad and the iOS PSK-31 app called PSKer. This week I made some modifications to my setup. This included adding a USB extension cable and I experimented with the VOX settings of the KX3.
Thank you for watching!

An iPad, PSKer iOS App and KX3 = FUN
As I briefly mentioned in my blog post titled KX3 – The First 24 Hours. I spent a little bit of time experimenting with the iOS App titled PSKer. This experimentation included operating it in an over the air method. Meaning I have no audio cables running between the iPad and the KX3. I’m simply relying on the iPad built-in microphone to pick up the audio signal from the KX3 speaker for receive and using the iPad speakers and the KX3 microphone for transmit. The image below is a snapshot from the PSKReporter website. I’m running 5 watts into a ground mounted Hustler 6BTV. My transmitted audio IMD is –34 as recorded by my KK7UQ IMD Meter in the shack.
Of course, an optimum setup would include some sort of audio interface to directly connect the KX3 and the iPad. While I’m still looking into these options, I’m fairly pleased with the performance in the testing. Also, while I had always envisioned this process to be a bit awkward by having to hold in the PTT mic switch and fumble with typing on the iPad. The KX3 makes this much easier with an XMIT button. I can press the XMIT button on the front of the KX3 and the rig will switch into transmit mode until I press it again. I think this is better than using VOX. All I need to worry about is making sure the microphone is positioned near the iPad speakers and the iPad is near the KX3 speaker. More about the KX3 speaker in just a bit.
While I would not opt to use this setup in the ham shack. I’m thinking this will be perfect for SOTA activations. Again, I think a direct cable solution is optimum, I’ve not seen any schematics or plans anyone has designed to date. At a minimum I believe the iPad needs to receive audio from the KX3 via a cable. During the maiden SOTA activation for the KX3, I realized just how weak the KX3 speaker is in an outdoor environment.
With a light breeze and the KX3 sitting on a foam pad on the ground, I had difficulty hearing stations on SSB. I had to use my ear buds and even those proved to lack the quality when connected to the KX3 (as compared to my 817). Of course, what do you expect with a $2 pair of cheap ear buds. I will look into other alternatives before the next activation.
Final comment on the KX3 speaker. I don’t fault Elecraft. As I mentioned in my blog post titled KX3 – The first 24 hours, Elecraft has stated from the beginning that the quality of the built-in speaker will be compromised due to size and recommended either external speakers or earphones/headphones when using in a noisy environment. I’ve done a little research on the Chill Pill mobile speakers. These have been discussed on the Elecraft Yahoo reflector with mostly positive reviews. Weighing in at a mere 7 ounces, they won’t break my back or take up much room in my pack.
I did some testing earlier to see if I could feed audio from the KX3 into the iPad and the PSKer app. The picture below is the setup I used. The white piece is the iPad Camera Connection kit. This connects to the bottom port on the iPad and provides a standard USB connection. Connected to this (via USB) is a Plantronics USB soundcard adapter. I plugged a short stereo patch cable into the KX3 headphone jack and the other end into the microphone input of the Plantronics USB adapter. I connected a second stereo cable from the KX3 mic jack and the other end to the headphone jack on the USB adapter.This does work. But….
The weak link in this is the connection at the iPad. The iPad Camera Connection kit (the white piece) with the added length (approx. 3 inches) of the Plantronics USB soundcard device makes it hard to keep it all plugged into the iPad. On a SOTA activation I am sitting on the ground and will have the iPad in my lap. I can easily see where the connector will get unplugged. But as you can tell it does work. In the picture below I have my iPad running the PSKer App connected to the Elecraft KX3 via the Apple iPad Camera kit and the Plantronics USB sound card device.
I recently created a YouTube video where I discussed this setup and the items I used to connect the iPad to the KX3. I’m going to continue to experiment with other options and will blog about these findings at a later date. You can watch the video below.
Until next time…
