Radio, Amateurishly

 " PAN-PAN PAN-PAN PAN-PAN. This is sailing vessel SERENE HORIZON. I am taking on water about five miles outside Two Harbors and might need assistance." I barely had time to settle into my desk chair at United States Coast Guard Station Los Angeles/Long Beach. The latte that I grabbed on the way at Common Room Roasters is still nearly full. The scratch paper that I'll be taking notes on doesn't yet have a mark on it—at least not on the side that I'll be using. I'm using a couple of repurposed log sheets that I took to Dockweiler State Beach on my most recent Parks on the Air activation for scratch paper. The flip side of each sheet contains the call signs of twenty or so amateur radio stations that I worked the previous weekend. "Vessel in distress, this is COAST GUARD SECTOR LOS ANGELES. Say again your vessel name and the nature of your distress." I'm getting it all down—more neatly than I usually do—on an otherwise pristine sheet of scratch pa...

Legend has it Francis Ford Coppola sometimes lets himself into the kitchen To make himself a pizza. There's a strip club across the street And an adult novelty shop next door. The pasta is sublime And the wine's not to shabby either. The hostess knows most of the customers by name. This is Old San Francisco. The San Francisco of Bullitt And Dirty Harry. Before the nouveaus showed up. When it wasn't called venture capital; It was just money.  We share a bottle of wine And a cannoli And go book shopping at City Lights.

  I'm pretty sure I saw you. My radio was set up, as it is so often, on a camp table in my parking space where I was doing a Parks on the Air (POTA) activation. I was right next to the boardwalk, on the beach that is the last bit of land between the airport and the Pacific Ocean, the beach that I've flown over countless times. You were out for a morning walk on the boardwalk, effectively doing the same thing I was doing: enjoying an early Sunday morning by the ocean. Neither of us could honestly say we were there for the peace and quiet—the roar of departing jets every couple of minutes removed that possibility—and so yes, I was speaking into my microphone at just a little above a conversational tone, calling CQ and phonetically identifying my station as whiskey six kilo sierra romeo. As you walked by, I smiled pleasantly and tried to make eye contact. Your non-verbal response was a little different. If looks could kill, I'd be silent key, everyone shaking their heads, sayi...

I'm not a lawyer. Or a physicist. Or even a real engineer. This isn't legal advice, or a step-by-step guide to how to perform your RF-safety evaluation. This is just one ham's story about something interesting that came up in the course of trying to make sure his station was safe.   Earlier this month, the FCC's new rules regarding the need for amateur radio operators to perform a radio frequency (RF) safety evaluation went into effect. The specifics of the regulations, their purpose, and how to comply is a topic that has been well covered by people who have expertise on those subjects. This article won't be a deep dive on any of that. Instead, I'll summarize by making three points Exposure of human tissue to RF energy results in energy transfer that has the potential to cause skin burns, eye injuries, and other adverse health effects Most amateur radio activity occurs on frequencies and at power levels where those adverse health effects are negligible Because o...

What makes enigmatic music enigmatic One in a series that we'll have to see how it works out I must've come home late after a night of goofing off with my friends. There were a lot of late nights goofing off with my friends. Not yet ready for sleep, I flipped on the television and put on USA Network's Night Flight , an eclectic collection of short films, music videos, and cheesy old movies, all tied together by some cool  (for the time)  graphics depicting an aerial view of a nocturnal urban scene. On this early spring night in 1988, it was mostly music videos. The presenter was over the moon about a new (to her) Australian band who were sure to be the Next Big Thing.  Just four bars into the intro I found myself sharing in the presenter's enthusiasm. The key of A minor, but with a modal feel, an E minor seventh chord for the dominant rather than the more conventional E7. A bass line that never seemed to want to settle into root position. An unassuming vocal in a comfor...

  SAN FRANCISCO—It appears as though the lack of exposure in the For you feed and the inability to participate in Twitter polls aren't the only unpleasant surprises in store for those Twitter users who have rejected the Twitter Blue subscription model. Starting April 15th, all Twitter users who are not currently Twitter Blue subscribers will have to pay for each tweet. "The pricing plan is quite reasonable," Elon Musk said in a recent press conference, "starting at two cents". The tech mogul and owner of Twitter went on to explain that the first character in a tweet will be billed at two cents, the second character four cents, the third character eight cents, and so on, with each character costing twice the price of the previous character. After a minute of pounding furiously on her iPhone calculator app, a reporter for Reuters pointed out that a 280-character tweet, the current limit for those who are not Twitter Blue subscribers, would be billed a price that...

The National Park Service preserves unimpaired the natural and cultural resources and values of the National Park System for the enjoyment, education, and inspiration of this and future generations. The Park Service cooperates with partners to extend the benefits of natural and cultural resource conservation and outdoor recreation throughout this country and the world.   -United States National Parks Service Mission Statement In January of 2023, my wife and I visited Joshua Tree National Park for what was to be my third Parks on the Air activation at that site. The day before our trip to the desert, my wife and I watched a couple YouTube videos, including one produced by Allison Anderson. In the ten-minute video , Ms. Anderson shows a number of points of interest in the park, but almost more importantly, she shows off the AirBnB just ...
