Linux in the hamshack

I have endeavored to have my hamshack be 100% linux for a number of years. Licensed in 2001, my ham career really got going when I returned to the States in 2005. Upgrading to General and getting on HF, I integrated a computer into my operations. Ham Radio Deluxe was one of the most popular at the time and I used it – great for logging, digital modes, and rig control. When I had fun with APRS, I used UI-View, which was Windows based.

My first experience with linux was in the late 1990s. I had limited success. Not much later, Ubuntu gave me more of an opportunity to use linux for meeting my requirements for computing. I began to dip my toe in, using linux for rig control and logging. I switched to Mint around 2010-11. I found that Mint was easy to use and allowed me to use fldigi for digital modes, rig control, and logging. ARRL’s LOTW could also be used with linux and was integrated into fldigi. It was hard to find any aspect of the amateur radio hobby that required a computer and could not be done with linux.

Except, in my case, for one area of pursuit. APRS and my weather station. I had become a Davis Instruments fan since I got my first weather station in 2005. As mentioned before, UI-View handled the APRS portion and Davis had its own Windows-based software for handling the weather data the console produced. Back in 2011, the standard for linux-based APRS was Xastir. Xastir is a solid application and I had success using it to handle both internet and RF APRS traffic. But Xastir would not play well with the Davis Vantage Pro2. There was internet talk of a work around using a MySQL database. I had no luck. I kept my system on Windows, using UI-View for weather and APRS.

About two years ago, my Vantage Pro2, which I had since I was over in Iraq in 2007, finally died. The sensor package was mounted off my chimney when we first moved in to our current house over a decade ago. A great location for the weather station as it it high and clear of obstructions. Our roof, however, is steeply pitched and not something easy for me to traverse. I had gotten a TV antenna installation guy to install it – he did a great job. I think I had him back a few years later to swap out the battery. At one point, the board on the unit when bad and I replaced it. Then two years ago, one of our dogs shows up with an anemometer cup in her mouth. Perhaps a good sized chunk of hail had it the cup? Outside temperature data stopped working.

The old Vantage Pro2 with missing anemometer cup.

Rather than attempt to fix/repair the existing unit, it was time to replace. Over a decade is a long time to be exposed to the elements. I purchased a new Vantage Pro2 but then had a hard time finding someone to install. The local tv antenna guy took one look at my roof and said nope. A month ago we were getting our chimney inspected and cleaned and the gentleman was showing me pictures of the crown of the chimney. He’d just climbed up there. I asked if, for a reasonable fee, he’d be willing to swap out the weather station (and the VHF/UHF antenna). We struck a deal and now the weather station was operational again.

But could I still achieve my goal of a linux-based APRS/weather station? Enter weewx. This is an application that is like the Swiss army knife of weather station apps. I am not sure of what it does not do. The key aspect is that weewx produces a file (wxnow.txt) every minute using the same format used by APRS for weather data. Even better, the good folks at xastir created a script (wxnowsrv.pl) that copies the wxnow.txt information and pulls it into xastir. This was the solution!

And it works! Both weewx and xastir are happily working together on their own minimalist linux box, pulling in weather data from the Vantage Pro2 console via a serial connection while xastir is using a serial connection to transmit the weather data via my TM-D710A TNC functionality into the APRS system via RF. Weewx also creates a simple weather webpage which you can see here.

I kept a careful list of all the steps I completed in installing both weewx, MySQL, and xastir that I will post here soon – in case I need to reinstall. As of now the system seems to be stable and working nicely.

Morsum Magnificat

Morsum Magnificat – The Morse Magazine

An excellent resource concerning all things Morse code.

The English language edition of Morsum Magnificat, the Morse Magazine, otherwise known as “MM”, contained a vast amount of information and illustrations of interest to Morse operators, key collectors, historians, researchers and other Morse enthusiasts.

MM was first published in the Dutch language, by Morse enthusiasts, Rinus Hellemons PA0BFN, and Dick Kraayveld PA3ALM. They were later joined by Tony Smith G4FAI who helped them launch the English language edition of the magazine.

Published from 1986 to 2004, in 89 issues, with readers and contributors around the world, it covered every conceivable aspect of Morse telegraphy, past, present and future, in a truly international way.

Issues are available at the Internet Archive here.

CW from the mobile

About twice a month I have the opportunity to scoot out in the morning to a nearby park for an hour or two. I use it as an opportunity to make a few contacts to make sure my mobile setup is still working well. This morning I was out at the Wyandotte County Park.

I was able to make five contacts on 40M. Some interference form shortwave broadcasts, but nothing that fully prevented a QSO. I enjoy using the J-45 leg key – it does not seem like it is a key built for speed. That’s okay for me as I am still somewhere in between 10 and 15 wpm.

When I get home and upload these contacts on to LOTW, I want to make sure that I have the correct location in TrustedQSL before I sign and upload the logs. I found two websites that helped me figure out the grid location for the park. The first is QRZ’s Gridmapper. The second website was a bit more user friendly and also provided the ITU and CQ Zones. After I set up a new station location in TrustedQSL and had transferred the contacts from my pocket notebook to my fldigi logbook, I exported the contacts and then signed and uploaded them via TrustedQSL into LOTW. Victory.

flcluster

I was able to get flcluster working with my fldigi logging and rig control program.

Easy to download right here.

I believe the original idea behind a DXCluster was that it was run on a local VHF packet network. You could then share DX spots with those in your area as propagation would be similar and the chances of others nearby working the DX higher.

There is access to a packet cluster in Kansas City but it is via telnet, which the flcluster can easily use.

Set up was easy and I was off and running.

The Zombie Shuffle

I participated in a CW QRP event! Why not? It was actually a pretty good time.

The event: The Zombie Shuffle

The whole purpose is just to have fun. They are not looking for speed racer code operators and everyone is welcome.

The exchange is the best:
(1) RST
(2) your states
(3) a Zombie number, which is east to get. Or you can just use your area code.
(4) your Zombie name. This is the best part. You can just pick your own Zombie name being as creative as you want.

I had a total of 13 contacts (that’s pretty spooky in and of itself). Some of the fun names I worked were: Grim, Creepy, Gorigor, The Thing, Itt (as in Cousin Itt), Elvis, and Booger.

Fun stuff.

What’s Going On In The Shack

The big news, we finally completed some antenna maintenance. A few years back I hung a dipole up in the trees on the north side of the house. The weather took its toll. The line holding the center point had disintegrated, dropping the middle about ten feet. The east leg also lost its anchor and was resting on some branches. A sad situation.

This time I used heavy support line on all three support points. I also used my CSV19 Pneumatic Antenna Launcher, which worked great as always. I need to some finishing work, but I hope the antenna is good for at least the next six months.

What I will try to do, if I get the time and the weather cooperates, is place pulleys up in the trees I normally use to secure the ends of the dipole. I am also going to try to put up a 260 feet dipole and see if I can mess around with 160M… of which I really have had little experience with.

Progress is being made with the Morse code. I have written before about my winding path in learning the code. I had a good time this past summer on our camping trip making Morse contacts from the mobile (while parked) and using a J-45 leg key.

J-45 leg key

In the shack I have been making my way through the different levels of the SKCC (Straight Key Century Club). I had joined the organization way back in 2007, not to long after SKCC was established, but had not done too much with it. When I finally embraced the idea of using a straight key, I used my SKCC membership number to gain experience by taking part in QSOs with other SKCC folks (you almost always hear the CQ SKCC on the CW subbands). I would exchange numbers but never tried to work through the membership levels (Centurion, Tribune, and Senator). I did not want to spend a lot of time messing with extra logs or any type of additional paperwork. Then I discovered the SKCC Logger, a custom designed piece of software that will take your existing logfile and process the log for the appropriate data needed to submit for climbing through the ranks.

Although I am not able to get on the air everyday, I try to get on five days out of the week and log three or four Morse contacts. Before I get on air, I put in about ten to fifteen minutes practicing receiving and sending. My end goal is to reach a proficiency level of 20 words per minute. And I define “proficient” as being able to hand copy text without error for one minute. I need to take a look at ARRL’s Qualifying Runs and see when I can see where I am at.

To take the new dipole for a spin, I spent part of the last two weekends participating in OMISS nets. OMISS is a worked all states net. Last weekend was the 40M net, this weekend I tried 80M. I had not participated in a net since early 2020. The net controllers and participants are always great. Last night on 80M I ended up having a ton of contacts with some great reports, convincing me that the new dipole is doing the job.

Yaesu FT-2800M

It is time to clear out some space in the shack. I got the FT-2800M a while back and have always been impressed by its performance. I never used it in the mobile. It briefly had a life as a shack rig, but was soon displaced by the Kenwood TM-D710 for my APRS weather station.

Here is the original Yaseu flyer talking about the capabilities of the rig as well as a link here to the ARRL QST review. I hope I can find a good home for this wonderful rig.

2022 – The Summer Trip

St. Mary Campground, Glacier National Park, Montana

Another summer trip has come and gone. This one did not feature any new locations or set records for being away from home for the longest time. We did discover some new trails in Yellowstone as well as getting to know older trails in Grand Teton in different ways. The consensus for favorite hike was the out-and-back we did in Paradise Valley, not far from Fishing Bridge in Yellowstone. Ask me some time about the Solfatara North trail with the grizzly who wanted to take us out to dinner (take us out as in kill us… and then we’d become dinner). Or maybe it is best not to bring that hike up at all.

At times it seemed like the odds might be against us. Primarily with the June 2022 flooding in Yellowstone potentially putting a large chunk of our summer at risk. A new menu prevailed with a few winners and a general request for less potatoes.

The wildflowers were sensational, as always.

The culminating event, when we were down to Emily and myself, was a hike around Jenny Lake. What a blast!

Something new this trip was my increased attempts at getting on the air this year. Usually I do very little amateur radio work on the summer trips. To be honest, I am normally either too busy or too tired to get on and enjoy radio. This year I made an effort to get on the air and see if I could make some CW contacts. Although I had visions (and most all the equipment) to setup an operators position at the back of the station wagon, I ended up making all of my contacts from the driver’s seat. Helping me was my J-45 leg key and my Field Notes memo book for handcopy. When I did get on air, I was generally successful in making contacts. My best luck was on 20M around the SKCC watering hole at 14.055 MHz. An enjoyable aspect to making the contacts was sending each one a postcard from the national park I was at… using the postcard as a QSL card. Overall, I made eleven contacts – beating any previous year by quite a bit.

Today I upload the contacts to LoTW after figuring out how to add the locations from where the contacts took place into my LoTW account (three separate locations). Then, after I had entered the contact information into my fldigi-based logbook, I exported the contacts, using the correct location, into LoTW. It was nice to see many of my contacts had already confirmed the contacts.

I do need to make some modifications of my HF vehicle installation. The display heads up front are great! Using the Ram setup really made things organized and solid. The FT-891 in the rack tray needs to be adjusted to mitigate its ability to bounce too much on a bumpy road. I also need to repair the feedline into the radio. This fall, I would like to try out a back-of-the-vehicle setup.

As always more and consistent Morse practice will always yield dividends.

The Adventure in adventure-log

This missives here are related primarily to one of two things: amateur radio or summer camping.

Since I retired from the Army, we have spent a portion of the summer traveling around the country visiting national parks. Trips (a better term is adventures) have ranged from well over two months to about three weeks. We have been out to Maine’s Acadia National Park as well as Washington’s Olympic and quite a few in between. A few of the parks I have been to many times over the last ten years. Yellowstone has probably been the most traveled to, although not my favorite. That title belongs to Glacier National Park. Another favorite is Grand Teton National Park, just south of Yellowstone.

This summer is a greatest hits tour: Glacier, Yellowstone, and Grand Teton for a total of four weeks. Not as long as I prefer, but other commitments take priority.

Part of our families tradition during our national park rambles is to play a variety of games. Some of these are straight forward like Uno, Skip-Bo, and Yahtzee. Others are a bit more obscure: Sparkle Kitty, Farkel, and Guess That Park (national park trivia). This year, as the girls are now both teenagers, we are uping are game play to include two include two classics: Spades and Hearts.

While growing up, our family frequently played various versions of Gin Rummy. I have many a fond memory of playing cards at the houses of relatives or at the family camp we used to go to up in the Sierras. My first posting in the Army was to Fort Wainwright, Alaska with an aviation unit. I learned quickly that while we were in the field, when we were not flying or preparing for a mission, we would play cards. The game was not Gin Rummy, but instead either Spades or Hearts. Both were great fun and we had a great time. So, this summer we will give Spades and Hearts a try and see how it goes.
