  • You learn something new every day: screw extractors
    About a year and a half ago, I bought an Icom IC-2820H at the Findlay hamfest. It included the UT-123 option, which is a board that you plug into the main board, which gives it D-STAR capability. I mentioned in a previous post that I’d be willing to remove and sell that board as there […] The (...)

  • Partly-baked idea: Does amateur radio need more marketing?
    Warning!! This is a partly-baked idea, so go easy on me….Dan I worked for Northern Telecom (NT) from 1985 to 1991. They had purchased a company here in Ann Arbor, MI and formed a division that was developing an integrated voice and data system, called the DV-1. It used quite sophisticated (...)

  • Balun or no balun?
    On the Elecraft-KX mailing list, an item popped up on a topic that I’ve been pondering for a while. Titled Balun necessary? Barry N1EU asked the question: I’m planning some 40M-15M portable operation with a 44ft doublet fed with 25ft of twinlead into the KX2 ATU. Is it, or is it not, necessary to (...)

  • We’re missing the STEM boat
    I subscribe to an email newsletter named Model D that covers community news in Detroit. The company that publishes it also publishes other email newsletters that cover similar news around the state of Michigan. In the last issue of Model D there was an ad for the SC4 STEM Fest. I thought to (...)

  • Operating Notes: Ice storm takes me off the air
    Last week, I’d signed up to do a turn as W1AW/8 as part of the ARRL’s Volunteers on the Air operating event. I had planned to operate 40-meter CW on Tuesday, Wednesday, and Thursday evenings. That was the plan, anyway. On Tuesday, I simply forgot about operating. My bad. On Wednesday, I wasn’t (...)

  • A nice find at the local library
    We have a really great library here in Ann Arbor. It’s won “library of the year” honors in the past, and it continues to do a fabulous job. In addition to books and magazines and music, you can borrow stuff like telescopes, energy meters, thermal cameras, and a bunch of other cool stuff. One of (...)

  • Latest browser tabs: G7FEK antenna, SWR, repeater activity
    If you’re like me, you have a lot of browser tabs open. These tabs have web pages that you keep meaning to get around to reading, but often do not. You could bookmark them, but bookmarking those pages just puts them out of sight, and they shortly become out of mind. Right now, I have […] The (...)

  • First impressions: IC-7610 vs. Flex 6400
    A little over three years ago, I got a pretty good on a Flex 6400. So, although I’ve been an Icom guy since the 1980s, I bought the Flex and sold my IC-7300. The Flex is a great radio, but after three years, I got a hankering for a radio with real buttons and knobs. […] The post First (...)

  • Operating Notes: Odd prop, is zero beating a lost art?
    Odd propagation A couple of weeks ago, I turned on the rig, tuned up on 30 meters, and called CQ. The first station I worked was KB8FCG. According to QRZ.Com, KB8FCG is 28.8 miles away from me. The signal was S9 here in Ann Arbor. That seems a little too far for ground wave, but […] The post (...)

  • My first PC board!
    One of the things on my ham radio bucket list was to learn how to use KiCAD and design a PC board. Being a newbie at PC board design (when I was an engineer, we had PC designers do the actual layout), I decided to do something simple. Since I teach ham radio classes, I […] The post My first PC (...)

  • NIST studies first-responder communications needs
    This article was published by NIST yesterday. I think that if amateur radio wants to remain relevant in emergency communications, someone needs to be reading these kinds of reports. Based on this survey, NIST produced 14 different reports. Here’s a quote from one of them, Voice of First (...)

  • From my reading list: The inner beauty of electronics
    Safari, the web browser that I use most often, has a feature called the “reading list.” It’s like a bookmark, but much more temporary. The list is meant to be a parking lot for sites that you want to read, but not read over and over. Once you’ve read it, you’re supposed to delete the […] The post (...)

  • Operating Notes: Auroral flutter, big pileups for TN8K, more new ops?
    I called CQ on 30 meters a couple of evenings ago and got a surprise call from R1DX in Saint Petersburg. What was notable about this contact was the auroral flutter on Vic’s signal. I wish I had recorded it. The sound is very distinctive, though, and Vic even commented on it. Here’s the great […] (...)

    Two more for my collection of QSLs from stations whose call signs spell words! Ken writes, “Thanks for the POTA QSO.

  • Operating notes: Do I have a stalker?, don’t be a macho CW op, DXCC update
    Over the past week, I’ve had a couple of odd QSOs. The first was with a guy who I almost think is stalking me. He has a tendency to call me right after I’ve completed a contact with another station. Usually, I kind of sigh every time I hear his call because he’s very hard […] The post Operating (...)
