    The Planetary Society is blaming a software glitch for causing its LightSail-A CubeSat to go dark, but the organization’s satellite team is hoping the situation is temporary and that it can reboot the CubeSat’s onboard computer. In a lengthy blog post, the Planetary Society’s Jason Davis said the LightSail mission “is paused, while engineers wait out a suspected software glitch that has silence...

    It still amazes me that I can do this. Well not me, but 5 Watts of RF energy can span the globe. To quote my son Joey, "What sorcery is this?" I had a quick lunchtime QSO with Chris G4BUE on 17 Meters. He answered my CQ and gave me a 559. I told Chris that he was 599+ and that he sounded like he was just down the street. Just 5 Watts from the roof of a Jeep, parked in a parking lot in Warren, NJ to a house in West Sussex, England. Just thinking about that - !!!! In the blink of an eye - less than the blink of an eye, my tiny signal traverses the Atlantic and made it to Chris' home.

  • Fight Over Point Roberts Radio Tower Continues in Court:

    29 May 2015 | 6:10 pm
    Few things could be more alarming during a personal phone call than suddenly being interrupted by the sound of yelling on a police radio. It has happened in the past because radio waves, if they're strong enough, can overpower home-based communications. The little-understood phenomenon, known as blanket interference, is the reason a group of Canadians and Americans oppose plans for five, 50,000-watt radio towers to be built in Point Roberts. The powerful transmitters would be located about 400 yards from Tsawwassen and its 23,000 residents -- but opponents have succeeded in stalling the…

I've peeked at Brian's booth at Dayton over the years, watching him get a little bigger and more polished. He's concentrated mostly on one product, the Sienna, a high-performance HF transceiver that you build (some of) yourself. They solder the hard stuff, including all the surface-mount, but there's plenty left for you. Before talking to Brian, I cover some odds and ends around the Hamvention. And I…

    Soon, it won’t cost a dime to get a vanity callsign. This according to the FCC’s Notice of Proposed Rulemaking, Report and Order, and Order, MD Docket 14-92 and others, released May 21. Notice that this is a notice of proposed rulemaking. The fee won’t actually be eliminated until Congress is notified of the change. That will take at least 90 days. “The Commission spends more resources on processing the regulatory fees and issuing refunds than the amount of the regulatory fee payment,” the FCC said. “As our costs now exceed the regulatory fee, we are eliminating…

    I hate to say this, but I learned absolutely nothing at the Dayton forums this year. The reason for this is that I didn’t attend a single one. Normally, I try to make some of the forums at Dayton, and in the past, I’ve even spoken at one. Not this year. Aside from perhaps the TAPR forum, the Antennas forum, and maybe the ATV forum, none of them really called to me. (A complete schedule can be found in the online Hamvention program.) I do regret missing the TAPR forum. They had a couple of talks on mesh networking and updates from Chris Tests, KD2BMH on the Whitebox Project and…

A few days later, as I was going to a radio club meeting, I happened to grab it, only to notice that it must have hit something on the way down and the LCD display had cracked.  Again, no big deal, I could have lived with that.

    K0NR
    22 May 2015 | 8:44 am
    This is an update to one of my most popular posts. We have quite a few licensed radio amateurs that are members of public safety agencies, including fire departments, law enforcement agencies and search and rescue. Since they are authorized users of those public safety channels, they often ask this question: Can I use my VHF/UHF ham radio on the fire, police or SAR channel? It is widely known that many amateur radios can be modified to transmit outside the ham bands. The answer to this question used to be that amateur radio equipment cannot be used legally on public safety channels because it…
  • Three Common Mistakes When Using Metric Units

    K0NR
    16 May 2015 | 8:57 pm
    A while back, I had someone point out a few errors I made concerning the use of metric units. This caused me to review the SI system to make sure I had it correct. (I am sure I’ll continue to screw up a few things but, hey, life is a journey.) The International System of Units, universally abbreviated SI (from the French Le Système International d’Unités), is the modern metric system of measurement. For a thorough treatment of the topic, take a look at the National Institute of Standards and Technology (NIST) publication: Guide for the Use of the International System of Units (SI).

An SWR of 1:1 is a perfect match; anything higher is less than perfect. SWR is an important amateur radio concept, one that is not that easy to explain so I am always on the lookout for training materials. HamRadioNow just republished this video of an excellent standing wave demonstration by Bill Hays, AE4QL. Bill actually goes well beyond just standing waves and shows some antenna and transmission line theory as well. If you just want to…

    Last weekend, I had a fun time working the CQ WPX contest on SSB. I’ve always liked the format of the contest with the callsign prefix as the score multiplier (e.g., K1, K2, W1, W2, VE1, VE2 are all multipliers). Its like every new contact is a multiplier. This contest attracts plenty of DX but unlike some DX contests, everyone works everyone. Consistent with the contest, the CQ WPX Awards Program issues operating awards based on callsign prefixes. The initial mixed mode (CW, SSB, digital) award requires confirmed contacts with 400 different prefixes. Back in the 20th century, I kept…
