Then I got a call from VE3THR. Last year I'd talked to Tom when he was using his BITX40. This time he was on with his uBITX. FB. Tom's club in Barrie, Ontario is obviously melting a lot of solder and having a lot of fun. Here are some pictures of their rigs.

BITX Night on 7277: First N6ORS and then Canadian BITX Builders
I was about an hour late for the Eastern time zone meet-up at 7 pm local on 7277 kHz Sunday night (my wife and I watch 60 Minutes at that hour). but I figured I could work some guys if I got on at 8 pm. Sure enough, I was called by Keith N6ORS on his MIN-X rig. I was on my QRO DIGI-TIA. It was great to catch up with Keith.

F5LVG's Nail Board Receiver -- Names for the Technique
Pete WB9FLW reminds us that Olivier F5LVG has LONG been using copper nails and wood boards to build amazing rigs. See above for one magnificent example. That, my friends, is a superhet receiver. Inspirational!
A few posts back we asked for nominations for the official name of this technique. We still have to consult with Steve Silverman on this, but the nominations are:
Armand WA1UQO (perhaps reflecting his proximity to Washingotn DC) "Wire-Tapping"
Gary Hinson: "Coffin Dodging" (sounds a bit dodgy to me).
And the front runner so far, from Melbourne, Australia -- drum roll please:
Peter Parker: "NAILBOARDING." (Peter thinks he nailed it with that one. I tend to agree.)

Youngest Homebrew Hero: 17 year-old Sam Zeelof Makes His Own Integrated Circuits
Seventeen year-old Sam Zeelof, KD2ENL, is making his own integrated circuits in his garage.
Wow. This makes me think about another seventeen year-old -- the fellow who appears on pages 63-64 of Cliff DeSoto's "200 Meters and Down." (I have the story on page 81 of "SolderSmoke -- Global Adventures in Wireless Electronics.") In the early days of radio that kid amazed us by making his own vacuum tubes. Sam Zeelof is clearly following in that tradition.
No "mysterious black boxes" for Sam! No "appliance chips" for him! FB OM.
This is really amazing. Here are the links:

A Construction Technique that REALLY "Nails it" -- But what do we call it?
Thanks to Rogier PA1ZZ (long in W6) for this. I guess I have used a variation of this technique in some antenna tuner projects, and maybe in a crystal radio effort. This also reminded both Pete and me of the electronic project kits that we were given as kids. Those kits had little springs that were supposed to keep the components in contact. They might have worked better with nails.
This technique definitely provides an opportunity for an earnest young guy to make use of his soldering GUN. I don't think a wimpy 35 watt iron would be up to the task.
What should we call this technique? We have "ugly" and "Manhattan" and
"Muppet Boards." What do we call this?
"Muppet Boards." What do we call this?

NN2K's Beautiful Pine-Board Al-Fresco Thermatron AM Transmitter
On Saturday mornings (around dawn) I often listen to the Old Military Radio Net on 3885 kHz. I find it inspirational. This morning the inspiration was provided by Rick NN2K. His signal from Binghamton New York was makeing the trip to Northern Virginia. When I heard him mention that he was using a "Pine Board Transmitter" I felt the urge to look for a picture. QRZ.com provided the photo.
Rich says he built this rig in January 2018 based on a QST article by Bob Heil. FB Rich!
And thanks to Ted W3PWW for running the Old Military Radio Net for so many years.

KE4MIQ's Repurposed Raduino Receiver
FB James -- Really glad you are listening, and that you are having fun with a Direct Conversion receiver --- souped up with a Raduino!
Bill, Pete
Just listened to #204. (New Listener)
You talked about using the Raduino with other radios.
Attached is a pic of the ZZRX-40, Raduino, and Goodwill Sony speaker with Jameco stereo amp, all running off of Harbor Freight 9v Nimh rechargables.
