A Secret Little Adventure Ham Radio Blog
Skip KB1CNB and the Bristol County Repeater Association did it again with the fifth amateur radio direction finding event! AA1F and I will not miss these (click here, here, here, and here for blogs). The premise is largely the same as always, involving a 10 mile radius centered around a bridge in Fall River MA. …
Thank you Pi K1RV for letting me come by the K1USN club house and play radio. I had a fantastic time as always! Especially after I learned all about the audio gain knob 😉 Always great hanging out with the crew!(And thanks Joe WB1EMS for the video which I embedded in this post. I seem …

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 …
