Show Notes #086
- Tonight’s episode is proof that LHS is at least as popular as the All-Star Game.
- 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.
- 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.
- Contact Richard at [email protected], Russ at [email protected], or both at the same time at [email protected]
- Listen to the live stream every other Tuesday at 8:00pm Central time. Check the LHS web site for dates.

LHS Episode #084: GNU Radio
The 84th installment of your most favoritest podcast is now in the wild. As you may have noticed, we make a lot of assumptions about our listeners on this show; for example: You all love us. We have a good show in store for you today, including antennas made from electric fencing, a question about whether GPL software can be profitable, and most importantly a look at software defined radio and the GNU Radio project. Towards the end we address some feedback, solve a technical problem in Italian and try to stage an intervention for one of our more peculiar fans. ALL THIS WEEK on Linux in the Ham Shack!
