WSPRing on 6m this afternoon and I captured this trace:

I’m not seeing anything else, though F6HTL spotted my transmission 2 minutes later. I wonder what type of propagation that was?

(Interesting that WSPR decoded the transmission even though the signal was only present for half a cycle.)

Introduction:

• Tonight’s episode is proof that LHS is at least as popular as the All-Star Game.

Topic:

• Interview with Bob Finch, W9YA, principal maintainer of yfktest.
• Bob got involved with the yfktest project because he was looking for a logging program like the old DOS program, WR9R.
• His ideal logger did not use graphics, did not require a mouse, and was very easy to learn. yfktest was close, but had a few problems, so Bob began submitting fixes and improvements.
• Over the past year, Bob began submitting code changes and eventually became the principle maintainer of the program, and has made over 150 patches in that time.
• Russ described his problem with the program for Field Day logging. Bob explains that the issue was due to the error checking, and had Russ not tried to enter the signal report into the Class field, it would have worked fine. Russ suggests having a line of text above the fields that provides hints as to what each field should contain. Bob added that to his To-Do list.
• yfktest is written in Perl, so no compilation is necessary to install.
• Bob is working on a version that is completely contained on a USB stick that would be operating system agnostic.
• Rudimentary networking features are in the code now, but disabled. So, it’s possible that networking might be a future enhancement.
• Get your copy of the latest version of yfktest by following the instructions in the README.NOW link at bfinch.net.
• Bob then describes another of his interests, rocketry, and is involved in the open source/open hardware rocketry project Altus Metrum.

Feedback:

• Rich, KD0BJT, of the Low SWR podcast writes to tell us of a Field Day logging program called fdlog. It’s written in Python and has networking capabilities for multiple stations. Rich also mentions the Java-based logging program JL. Thanks, Rich. fdlog is a graphical Field Day logging program written in Tcl/Tk, but hasn’t been updated in about a year.
• Leif, KC8RWR, sends us a link to a series of Youtube video tutorials for GNU Radio, the open source software project for RTL Software Defined Radios. He wonders if he could use an NE602 at the front end of the radio for HF, and use a Raspberry Pi to run GNU Radio. Our hosts discuss this and the Signetics NE602, a balanced mixer and oscillator on a chip.
• Dave, M0DCM, has been catching up on LHS episodes while convalescing. He describes his system for listening, and some experiences with the Ettus SDR, Funcube Dongle, and digital modes with his new Yaesu FT-817ND.
• David, KE0AZ, tells us that the power output of the Ettus transmitter daughterboards is anywhere from 50 to 200 mW.

This evening I wanted to get on the  radio to catch some DXCC's for my Diamond ARRL award. The bands were not to full of the DX  that was needed for my DXCC award BUT St.Pierre et Miquelon
is a self-governing territorial overseas collectivity of France and is just outside of Canada, some Canadian hams were there making contacts on 20m!!! It was a DXCC I did not have and it's more or less local....easy peasy.............so I thought. The pileup was huge and I never did make the contact. Later in the evening they were on 40m but I was not able to hear them at all. It seemed I was the only one not able to hear them by the size of the pileup. Oh but earlier China BY5WJ was on the cluster and I thought "what the heck " and holy cow there were LOUD AND CLEAR....I gave them a go but again the pile up was big but I wanted to stick with it as they were just blasting in. While others were making contact I went to QRZ.COM to get some info as I always do...........this is what I found........

 Oh and I already have Jamaica' well it was good I found out before calling "BY5WJ" for 30 or more minutes. Lesson learned be careful even of the DX cluster spots. As a side note this is a mistake I or anyone could make and it's nice Josh put the info up on QRZ.COM to clear the fog.

My good friend Rem K6BBQ has completed his Field Day video.  As usual, it’s a hoot to watch.

But Rem ….. 50 Watts?  100 Watts?  Seems to me that Buddistick is awful close for that kind of power, Bud!  Make sure you don’t glow in the dark!

All teasing aside, it looks like Rem had a great time; and I wouldn’t have minded being there to give him a helping hand as his logger, or perhaps his official burrito taste tester?

This week I conducted a presentation on amateur radio for a neighborhood historical group.  I was a bit nervous going into this as it was my first attempt at explaining our hobby in a presentation to the general public.  For me it’s a challenge to capture the full essence of amateur radio in 45 minutes and not use too much lingo or go off on tangents.  However, the presentation seemed to be pretty well received and I even got some laughs from the audience when talking about things like big antennas in backyards, interference, drinking beer at Field Day, and the 6 meter “magic band.”

This isn’t your grandfather’s amateur radio….

Explaining how radio waves bounce off the ionosphere

After the presentation we had wine, cheese, and various homemade dips and deserts.  I fielded a lot of questions and several folks told me stories about relatives who were shortwave listeners, hams, or radiomen in the war.  A good time was had by all, as they say….

I am sorry to learn via the blog of PC4T that Chuck W5PG passed away on 18 July. Chuck was one of our little community of ham radio bloggers. Losing one of our number is like losing a friend. In his last blog entry he wrote about his efforts to get fit enough to do a bicycle hike later this year. His passing is, to say the least, unexpected.

My thoughts are with Chuck’s family and friends.
