Hearing Too Much and Not Enough…of the Right Signal!
Field Day is once again happening later this month. Hearing everyone is a blast, no? Well, it might not be. Especially if it’s the ham at the table right next to you. The “sshh, sshh” sound of the CW op bleeding over into your SSB ban frequency or the nearby FT8 transmissions doing the same. But you’re forgetting the CW op hearing your voice signal peaks, too. Unless you’re listening to the monitor on FT8 (or other digital mode), you just might not reliably decode a QSO transmission. All in all, it’s just not the folks whom you want hear!
It might be time to include an HF bandpass filter system into your Field Day or other portable operation station(s). But what to do? Build a kit? Buy commercially assembled? Or some of both? This is the focus of my article that appears in the June issue of CQ Magazine.
I bought an HF BPF system covering 160-6 meters from an Australian company, VK-Amps, from their eBay store at a very good price. Here’s a picture of the assembly into a customized aluminum case on my workbench. I tested it for filter characterization comparison against N5DU’s DX Engineering’s comparable DXE-419 filter system. My portable ops team tested the two during the Mississippi QSO Party. How did it do? Take a look at CQ Magazine’s June issue!

Taking a stroll through transceiver time…
Something that has made me drift into periods of wonder for a long time now is to look through the websites or other historical sources of radios and transceivers manufactured for amateur radio. By just perusing radios over a lengthy period of time, one can gauge how and when the hobby made changes in the technology. As the author William Faulkner has said, “The past is never dead. It’s not even past.” If coverage of the 2022 Xenia Hamvention bone yard is any indication, Faulkner is indeed right about the technological past not even being past!
Anthropologists of technology tell us that:
Our technological change in transceiver technology lends itself to the social change in how we practice amateur radio. I’ll focus on just one element that has emerged in the last decade, the panadapter effect, in a later post. But for now, let’s just get a grasp of the bigger picture. For it may not be what you thought, if you’re a long-time amateur radio operator. The pending demographic changes that I’ve written about unmercifully suggest that some won’t see the changes that tech imposes on cultural shifts.
But technology moves onward. The changes that improvements and revolutionary creations do begat collective change, even if the past still is among us in terms of usage or just in our hearts and minds. Those images and feelings are demographically rooted, however, in the time in which our early years are imprinted in our memories.
It’s quite an amazing walk to just browse through the dates that radios in Rob Sherwood’s table of receiver tests were released to the market. I’ve put a simple time line page in the portfolio of Sherwood Tools for the viewer to easily do that. I’ve added links to pictures and details of each radio for a richer experience.
Return to the year you were licensed or got seriously interested in amateur radio. What’s the nearest year in Rob’s Table? What was the technology of that radio? What was your first transceiver? Locate your amateur radio life course regarding transceivers through Rob’s bench test list. Then, check out the other Sherwood Tools to see how it fits into the latest rigs.
After this new page was circulated by Twitter, I received this kind note from a popular SOTA award winner, Ed Durrant DD5LP in Germany:
While it did take a minute, the results are hopefully well worth it. But just taking the Sherwood Table and placing each radio into the year of market-entry, there is a look at over a half-century of technological advancement in this time line. How has it made us change our behavior in operating? How has it changed the organized hobby itself? And what will tomorrow bring? Go take a stroll through transceiver time here.

CQ WPX CW contest….well I started with great hopes!
Intentionally left upside down as this was how things turned out. |
Well here we are it's Monday and as I look back to Friday and the dreams of contest sugar cookies dancing in my head and how things can change! The contest was the CQ WPX CW contest and as of Friday evening I was all ready to give it a decent go. The propagation numbers were not in our favour as the Kp index rolled up to 5 and thus lots of signal QSB.
It was Saturday morning and I was just beginning to call CQ TEST when my dear wife came in and announced "I think I hear water running come and have a listen". Those words are any given day are not what you want to hear. The contest came to a grinding halt and it was taken over by contractors, plumbers and various odds and ends. I was able to get in and out of the contest but only for very short times. The outcome was a poor showing but a better and upgraded plumbing!
For the limited time I was in the contest here are some of my take a ways from it:
As said the conditions on Saturday were poor and I found myself calling CQ TEST and as time past with no answer my mind began to wonder. Looking around the shack, looking at the operating desk and icons on the desktop. Then all of a sudden an answer came and I was not at all ready for it. Thus repeats and some frustration.
I really wanted to work in the contest at improving my run abilities and it was just not happening as I was calling CQ TEST sometime for over 10 minutes with no answer. I then went to search and pounce and did up my score that way. Lesson learned....go to search and pounce when calling CQ TEST is just not happening.
Murphy did hit me with the plumbing issue as well my own carelessness...for example when I setup my CW macros and tested them before the contest I turned the power out to zero. Well this ham radio guy forgot to turn the power back up to 100 watts and for about 20 minutes I was calling CQ TEST with ZERO output!! To boot the radio have a LARGE meter showing zero out and my LDG tuner has the same. Lesson learned to pay attention and not to wonder.
Not much else and since this is not a home repair blog I will skip the very expensive plumbing repairs.
Below is the final score.
