    Random Wire Reflections for Issue 97
    Jul 1 2024
    Good afternoon. KJ7T is in the booth! This is Tom Salzer with some Random Wire Reflections for Issue 97 of the Random Wire Review that will publish on Friday, July 5th.And I have to laugh a bit when I saw I'm in the booth, because the reality is I'm at my messy sit-stand workstation at home, early in the morning when it is quiet, and just pretending that I have a recording booth!I actually recorded this podcast inside the passenger compartment of my Honda Ridgeline truck while waiting for my daughter’s prescription to be filled. I captured audio on my Zoom H4N Pro Handy Recorder with a “dead cat” filter over the sensitive microphones. The audio was later imported into Audacity for final editing. I exported the audio in mono to save space, making this podcast a bit more friendly for folks using cellular bandwidth to listen.OverviewOK, let's take a dive into Random Wire Review issue 97. Topics in issue 97 include: * Independence Day;* a new (to me) Dakota Lithium battery;* the Digirig Mobile and Digirig Lite devices; and* a terminal node controller by MFJ. I also offer some reflections on encryption of radio traffic and on APRS. The closing notes include a short bit about cloning my hotspot microSD card, a sound clip from an AllStarLink net, and a few photos from the Hillsboro Hops baseball game.If you are interested in AllStarLink, you’ll want to stay tuned to the very end where late-breaking news is shared about a major version upgrade for AllStarLink!Independence Day EditionSince issue 97 will publish on July 5th, I'm calling it the Independence Day Edition. On July 4th, my wife and I will attend a baseball game that pits the Hillsboro Hops against the Eugene Emeralds. We'll try to eat a few hot dogs, have a beer, and watch the fireworks show that will be featured at this game. Usually we get together with family, but having a night out for the two of us seems like a great way to celebrate Independence Day this year.In issue 97, I refer readers to a Reddit thread about the First Amendment and ham radio. Reading through those comments helped me appreciate the many privileges we enjoy as licensed amateur radio operators even more.New Lithium Iron Phosphate BatteryI succumbed to a deal on Facebook for a 12-volt, ten amp-hour battery from Dakota Lithium, for $69. That’s a nice price for a portable battery.This little guy is a bit larger than my off-brand 12.8V 6 amp-hour battery by TalentCell. I'm surprised the Dakota battery doesn't weigh much more than the TalentCell battery.I tested the battery by clipping the power leads from my Ten-Tec Scout 555 to the spade lugs on the Dakota battery. It worked great and I can tell this is going to be a mainstay in my ham radio kit.Digirig Mobile and Digirig Lite devicesI have a Digirig Mobile device that I bought because I couldn't get an MFJ TNC some time ago. The Digirig device works great. It's about the size of a large thimble, as in the protective device you put on your thumb when sewing. Actually, the Digirig kind of blows my mind. Essentially, it's an external sound card that is just tiny. The catalyst for me to look again at the Digirig products was an issue of Steve Stroh's great newsletter titled Zero Retries. Steve included a bit about the new Digirig Lite device that incorporates some of the needed cabling into the device. I love a tiny and complete solution so the Digirig Lite is on my "must acquire" list.If you like content that is interesting and future focused, produced by an experienced and capable ham, I recommend Steve's newsletter to you. A subscription button is included in issue 97 of the Random Wire.A New TNC Arrived in the ShackAnd speaking of terminal node controllers, Steve's mention of the Digirig Lite caused me to remember why I bought the Digirig Mobile, so I went looking for an MFJ 1270X TNC again. Most vendors I checked list this device as out of stock, but Ham Radio Outlet had some in Sacramento.I very swiftly logged into my HRO account and ordered up another 1270X. It arrived a few days later. I include unboxing photos in issue 97.Encryption of Radio TrafficI overheard an interesting conversation from an east coast reflector while on a morning drive for the coffee that fuels the start of my day. Somehow, those hams got onto the topic of encryption of radio traffic by city, county, and state agencies. I reflect a bit on this in issue 97. I'm of two minds. Normally I would prefer radio be open to all. But I've been in the public safety arena and I understand the need to protect people, families, businesses, and public officials. If encryption makes public safety officials safer and better able to do their jobs, then I support it.How Do You Do APRS?I actually did laugh out loud when this title popped into my head because it echoes a line in the 1980s movie The Last Starfighter. In that scene, an alien astronaut is meeting the hero's friends and family on Earth, and when one of the people asks him "How do you do?" he responds ...

    Random Wire Reflections for Issue 96
    Jun 24 2024

    KJ7T is in the booth! This is Tom Salzer with some Random Wire Reflections for Issue 96 of the Random Wire Review.

    Condenser microphone this week

    This week, I’m using the Blue Yeti Nano condenser microphone. It is more sensitive. I’m trying to talk across the mic rather than in it to help reduce the sibilants (the hissy “S” sounds) that are normal to my speech. I’m also recording into Zoom instead of Audacity, using the Zoom background noise filter to help quiet the sounds coming in from my environment. The final mix was done in Audacity.

    WIRES-X Nets

    A schedule of WIRES-X nets will be in issue 96 of the Random Wire Review publishing on Friday, July 28th. I found good nets for every day of the week.

    YSF Hotspot Died

    When I got home from several days of travel, I found that the hotspot I use for Yaesu System Fusion was not responding. I burned a fresh image to a microSD card and restored a previously saved configuration to get it back on the air.

    What is Your Legacy?

    “What is your legacy?” was a question posed during the Worldwide Friendship Net on June 8th. This got me thinking about my own legacy and I share my thoughts in this podcast.

    Node Remote App for AllStar Nodes

    I’m testing the Node Remote app for AllStar nodes. It isn’t working perfectly, but it does work. More on that in issue 96 on Friday.

    SHARI AllStar Node Telemetry

    I learned a tiny new thing with my SHARI AllStar nodes: the telemetry settings are not where I expected them to be.

    Differences in Generations

    This topic is not contained in Random Wire issue 96 — it is special to this podcast.

    One of the topics in a training last week was about how different generations view the world, how they were shaped by events of the time, and how they think and speak differently. I’ve been thinking about that, and perhaps this helps explain the division that I still hear when people talk about learning CW and about those of us who did not learn CW.
