Here in the DC area, the monument is very frequently in view. I have been up to the observation deck. We were here for the earthquake that damaged the structure. On Thursday night someone made a good video of lightning hitting the monument. This particular storm was flashing through my window, and was visible during a Zoom class through the windows of persons elsewhere in the area. This lightning storm took out one of NA5B’s amazing Web SDR receivers. I think it was only the LF receiver. I am sure Mehmet will have it back on-line soon. Here is an article on the topic: https://www.popularmechanics.com/science/a32781804/watch-lightning-strike-washington-monument/
Our good friend Farhan came to Northern Virginia last week for the 50th Anniversary Symposium of AMSAT. We were really delighted that he also came to SolderSmoke HQ. Elisa and I gave him a lightning tour of Washington DC (including a quick visit to The Air and Space museum) and then we headed back to the shack from some radio work.
In the picture above you can see my BITX-20 (that Farhan designed) off his right shoulder. Off his left shoulder you sits my ET-2 rig. I really wanted to show Farhan how well the N0WVA regen performs — he was impressed, especially when we started listening to SSB contacts. It was really amazing that we were doing this with just one J-310 FET. This was great fun. Farhan tells me that he will soon take up the “two transistor challenge.”
When he was here in 2017, I tried to demonstrate my version of Rick Campbell’s R2 Direct Conversion receiver. Unfortunately, when I tried to show off the “single signal” capability that is the whole purpose for this receiver, it was NOT producing a single signal output — you could hear the signal on both sides of zero beat. One of the small AF chokes I had used had gone open, knocking our one of the two DC receivers. This time I had the problem fixed and single signal reception was successfully demonstrated.
Farhan brought me two pieces of test gear that I have needed for a long time: A step attenuator and a two tone generator. Paired with his Antuino, these devices will bring about a big increase in capability on my bench.
It was really great to have Farhan in the shack. We had a great time talking about ham radio and homebrewing. Elisa and I both really enjoyed hearing from Farhan about his travels and about his life in India. We are all really lucky to be in the same hobby as Ashhar Farhan. Thanks for the visit Farhan.
Here is a quick video of Farhan tuning the BITX 20.
On April 12, Tom Gallagher NY2RF was in DC and was kind enough to make some time in his schedule for us to get together and talk about radio. As we mentioned on a recent podcast, Tom, who has recently taken over as Chief Executive Officer of the American Radio Relay League, is a true FB ham. He has a restored Drake station that he keeps on the air, and was recently talking up the Michigan Mighty Mite during his interview with Eric 4Z1UG in the “QSO Today” podcast. And he is a SolderSmoke listener. It was great to finally meet Tom.We are all lucky to have him at the ARRL.
I first saw that QRP Altoid-tin ATS-3b rig around 8 years ago in pictures that Jonathan-san sent from a beach in Vietnam. He and his family were there on vacation from Japan. (Included was a memorable picture of his young son in an NVA helmet.) During this time period Jonathan also tried (unsuccessfully, I’m afraid) to teach me how to properly pronounce the name of that famous electronics market in Japan.
Jonathan and his family were in Washington yesterday and we got together for lunch. It was great to finally meet them. And to see that well-travelled ATS-3b.
Jonathan is a big fan of the ATS-3b, and for good reason. A very neat rig.
Thanks to Farhan for alerting me to this great Hackaday article about a homebrew hero who was — sadly — unknown to most of us. He lived in Washington D.C., right down the road from where I live now. The Hackaday article leaves no doubt about it — Rufus Turner was one of us. He had THE KNACK. He was a true radio pioneer and homebrew hero. It is really a shame that we’ve known so little about him.
