Late Night NanoVNAing: Band Pass Filter Analysis For Friends That Don’t Like To Share

May 17, 2022 by KM1NDY

Lets start with the fact that there is no S2 port on the NanoVNA. There is a “1” port. And there is a “0” port. Or lets talk about that S12 measurements tell you how well a transmission goes from port 2 to port 1. NOT how well the power of the transmission goes from …

I Went To A Hamfest And Bought Pot(s)

May 10, 2022 by KM1NDY

Potentiometers for crying out loud…what the heck did you think I was talking about?!? And don’t get any ideas that you caught me here. I am a well-established straight-edged teetotaler. I came back from NEAR-Fest at the Deerfield Fairgrounds in New Hampshire two weekends ago with a box of variable resistors that only cost me …

The Ten-Point SOTA Return To Slide Mountain, & “There Won’t Be Snow In April In The Catskills”

April 27, 2022 by KM1NDY

There was snow. I only wore my crocs, my hiking shoe of choice but not for a foot of slushy, melting spring snow. It was 50 degrees. The peak of Slide was 2.8 miles away. Rock hopping up the base of the mountain made the early part of the trail easy. The trail was soupy, …

The Craziest Antenna That *Still* Never Was…

April 26, 2022 by KM1NDY

You may recall in this post, that AA1F and I were shut out of getting our SOTA point on Oak Hill W1/MV-006 near Concord NH due to a thunderstorm. This meant that I could not attempt to put that rusty twisted tangle of metal residing on the peak of the small hill on the air. …

Ham Radio Hodge Podge – A Week’s Worth Of RF Obsession

April 20, 2022 by KM1NDY

Look carefully at that radio in the picture above? Recognize it? I’ll come back to it at the end of this post. The odd places radio takes you. Below is Pocumtuck Rock in Deerfield MA.

The Impatient Ham’s Perfect Vertical Antenna (And A Bit More On That Random Wire Tuner)

April 12, 2022 by KM1NDY

AA1F was celebrating a special day, so he needed a special present. While our love of radio is simultaneously growing, our ambitions in the hobby are different. AA1F embraces the “appliance operator” label, wanting easy to deploy gear that consistently works so he can reliably and rapidly get on the air and make contacts. Me, …

Real Hams Don’t Leave Home Without A Tarp! And The Craziest Antenna You’ve Ever Seen That Never Was…

April 11, 2022 by KM1NDY

We would wake up early so I could scour the Seacoast Amateur Radio Flea Market in Hampton MA for some crystals and variable capacitors and then head over to the little bump called “Oak Hill” (W1/MV-006) for a Summits-On-The-Air activation. My ulterior motive, inspired by this thread on QRZ.com, was to use this as an …

DIY No-Solder, Cheap, Stupidly Easy & Simple Dipole Antenna (And By The Way, What Is An Antenna And How Does It Work?)

April 3, 2022 by KM1NDY

Are you a no-code, appliance operator type of ham who memorized the general class amateur radio test questions in order to be able to talk on the high frequency bands? Well, me too. Or at least I was. And then I got sucked into this weird 3+ year long vortex of RF lovefest. And, oh …
