A Secret Little Adventure Ham Radio Blog
Hoping my radio waves make the most of the salt water tomorrow on their way off to foreign lands. I’ve heard the sun may be coughing up a fireball (a.k.a. a coronal mass ejection). This picture shows the stations receiving my 200mW 20M WSPR signal from my home QTH from 1:00 to 4:00 UTC (9pm …
I lost my Nellie eighteen months ago. We had our secret spot along a tidal river. Perhaps you remember some of the old stories I told? Nellie learned a lot about life on these banks. And so did I. My new canine pal came into our life very shortly after the passing of Nellie. A …
As my ham radio journey takes me on a more formal study of electricity, my home laboratory grows. I remember purchasing the Tektronix 2465 a few years back on a suggestion of a friend, not having a clue what I was doing with it. I just knew that real electronics enthusiasts had an oscilloscope. Now …
From Top to Bottom: Not shown are my RigExpert VNAs, the NanoVNA, the Koolertron 60MHz function generator, the Tacklife 30V 5A variable DC power supply, and handheld digital multi- and LCR meters. On the bench is the Weller WE1010NA soldering station. Oh yeah, and my Elegoo 3D printer. I think its turning into a proper …

Well, apparently the fifth time is a charm…because THIS ONE WORKS!!! As you can see in the video and pics below, there are only really a …
This was a little rabbit hole. On some amateur radio forum somewhere someone mentioned the MFJ-802B RF Field Strength Meter. This piqued my interest because I had not realized that a field strength meter was a consumer accessible device. Turns out there are all sorts of RF meters and detectors available to purchase. Who knew? …
Scroll to the bottom if you are only interested in the FD checklist! Is Field Day worth it? This year, more than any other, it seems this question was popping up on ham radio forums across the internet. Other versions seem to be what is the relevance of FD in the day and age of …
For last year’s Field Day, I took a stab at networking a couple of computers together with an ethernet cable so that our N1MM+ logging software could be synced up. It was both surprisingly easy to do, but equally daunting due to the curious lack of reasonably digestible tutorials tackling the topic on the interwebs. …
With ARRL Field Day around the corner, it is the time of year where amateur radio operators far and wide wonder if they are going to be stuck having their QSOs wiped out every time their neighbor keys up the microphone. Interference between stations in a multi-transmitter field day operation can be the norm if …
