N0NB at 21

Posted on 16 Dec 2019 by Nate Bargmann 125 views

Me? No, I’m somewhat older than 21.  Dearie me!

It was 21 years ago today that N0NB became an active callsign in the FCC database assigned to me.  My callsign for the prior 15 years of KA0RNY was thus retired and returned back to the FCC.

About six weeks earlier over the first weekend of November 1998 I had spent the night at the home of my former neighbor John, KA7GLA (SK) in Enid, OK, to attend the annual Enid hamfest.  He had a callsign plaque in his shack (radio room) of W5ACW that had been held by a ham he’d known in years gone by.  He was considering changing his callsign to it at that time, but never did.  Well, that put a bug in my ear and when I returned home I started researching available callsigns to apply for through the FCC’s Vanity Callsign System.

Running N1MM+ logger with Wine on Debian Buster

Posted on 03 Dec 2018 by Nate Bargmann 3,638 views

I’m certainly not the first to attempt to run the popular N1MM Logger+ contest logging program on Linux through Wine.  I do think that I’m one of the few (NF8M, W2NRL (thanks to both of you for putting your experiences out on the Web)) that has found that this may now be possible after years of frustration.  Wine has clearly become more capable and short of N1MM Logger+ being written to work with Mono, hams wanting to transition away from Microsoft Windows to Linux may well have one less reason to prevent them from doing so.

A personal milestone and a look back

Posted on 03 Nov 2018 by Nate Bargmann 852 views

35 years ago on November 4, 1983 a somewhat nondescript government envelope arrived in the mail box.  It was from the FCC and was the fulfillment of a dream.  It was a Novice class amateur radio license issued in my name and it bore the callsign of KA0RNY.  Here is a scan of that document.

At that time the term of the license was for five years.  When I upgraded to Technician in early 1985, the term was ten years as it is for currently issued amateur radio licenses in the United States.

4 State QRP Group Bayou Jumper (Paraset inspired QRP XCVR)

Posted on 26 Jan 2017 by Nate Bargmann 9,488 views

Just before Christmas the 4 State QRP Group announced that a new kit is available, dubbed the Bayou Jumper. From its introductory page:

“Return with us now to those thrilling days of yesteryear” and build the Bayou Jumper. The name “Bayou Jumper” is a play on “Ocean Hopper”, a famous regenerative receiver of a bygone era. It retains that great retro look but with modernized circuitry. With it’s distinctive panel and wood box enclosure it pays homage to the famous spy radios of WWII. It is designed for the CW segment of the 40 meters.

Compiling WSJT-X 1.7.0 on Devuan Jessie

Posted on 23 Dec 2016 by Nate Bargmann 3,656 views

The latest version of WSJT-X, 1.7.0, was released on 19 December, 2016.  I found that the available Debian formatted package would not install as it is biult for Ubuntu 16.04.1 (and variants) which has a newer version of Qt5 on it than Devuan Jessie (as Devuan Jessie is mostly a downstream distribution of Debian 8, Jessie, these notes should apply to it as well).

My first introduction to amateur radio

Posted on 17 Dec 2016 by Nate Bargmann 2,129 views

It was early 1977 as I recall, probably just after New Years, I was 13, CB was big in the popular culture and I wished to be able to take part but a CB at the time was just too expensive for my parents to satisfy my radio curiosity on what they presumed may be a whim.

Running Electraft utilities on Linux amd64 and multiarch

Posted on 31 Jul 2016 by Nate Bargmann 2,226 views

At this time the Elecraft utilities for Linux are only available as i386 32 bit precompiled binaries.  Other architectures such as amd64 or armhf (Raspberry Pi) must use another means, if possible.  The Debian Linux distribution and its derivatives (Ubuntu, Linux Mint, Etc.) and forks (Devuan which I now run) have the capability to enable “multiarch” which allows running i386 32 bit binaries on an amd64 installation as a native application.

The following is a rough guide to set up an amd64 based installation to run i386 binaries.  The first step is to enable multiarch (if not already done so when the system was installed) by following the Debian Multiarch HOWTO.

After enabling the i386 architecture, aptitude shows about 24000 new packages the reason being is that now there are many packages available in both amd64 and i386 versions.

After some checking with the ldd system utility, I found that the following packages need to be installed:

libstdc++6:i386
libgtk2.0-0:i386

These pull in additional packages they depend on if a smart installer such as apt-get or aptitude are used.

The help functionality is not available without the installation of the following package:

libgtkhtml-4.0-0:i386

I currently cannot install this package on my present system, Devuan Jessie 1.0 Beta, due to a dependency error with the libgtkhtml-4.0-common:i386 package being unavailable.

As I use the Clearlook-Phenix theme on my Xfce desktop, I needed to install the following package for the Elecraft utilities to use this theme:

gtk2-engines:i386

Beyond the Help viewer issue noted above, I cannot view the release notes in the K3 utility but can view them in the P3 utility.  I store the firmware files in custom directories for each, which is odd that the P3 works and the K3 doesn’t.  If it’s any consolation, the K3 utility, Rev 1.15.6.27, doesn’t show it either on a native 32 bit installation, so I don’t think multiarch is at fault here.

Enabling sysvinit on Minibian Jessie 2016-03-12

Posted on 28 May 2016 by Nate Bargmann 2,202 views

As I was building a very minimal system for running APRX (N0NB-10) I chose to use Minibian as the starting point rather than stripping down the full Raspbian image to run on a Rasberry Pi model B.  Stripping the system to just those things that do their job and then get out of the way, I chose to enable sysvinit.  As I was doing this headless, I found that after installing the sysvinit-core package that I could not log into the system using SSH.  Hooking up a monitor and a keyboard showed that init did not proceed through the system startup.

Looking at /etc/inittab I found it to only have one line! Certainly not enough to properly start the system. As my current APRX digi is running a stripped down Raspbian Wheezy image, I copied the /etc/inittab file from it to the new system. Problem solved and init worked flawlessly as expected. I was then able to proceed to remove the remaining unneeded packages.

The resulting disk image occupies about 525 MB in addition to the boot partition. This is far from the leanest Linux based system, but as I am familiar with Debian tools, this still leaves a useful system that is dedicated to being an APRS digipeater and iGate. It fits easily on a 2 GB SD card. As I have several on hand, I can easily write a new image should a card suffer data corruption.

New weather station online

Posted on 16 May 2015 by Nate Bargmann 2,108 views

After ten years of reliable service, I have replaced the Peet Brothers Ultimeter 2000 with a Davis Vantage Pro2 wireless unit. This allows me to have the sensor unit a greater distance from the shack as it will transmit to consoles up to 1000 feet away at a location better suited for accurate measurements.  Data is being posted to the Weather Underground site and to the Citizen Weather Observer Program (CWOP).  Quality analysis will also be performed within a few days and the data should be picked up by MADIS by 20 May.

The hardware setup is the Davis data logger with a USB connection.  The software used is WeeWX, which handles archiving the data to a database and sending current conditions to Weather Underground once per minute and CWOP every ten minutes.  Future plans include transmitting the data to the local APRS amateur radio packet network, although a few things need to be worked out for that and an increase in local activity would be nice.

Regardless, the weather data is looking good over the past several days.

Defining your own happiness

Posted on 01 Nov 2014 by Nate Bargmann 2,329 views

Once again I had to relearn a tough lesson about letting one’s happiness be defined by others.  To wit, the heartbreaking end of the 2014 World Series for those of us who are Kansas City Royals fans.  I’ve been there before–1976, 1977, 1978, 1980, and now 2014–where the Royals just could not complete the deal in the last game of their season.
