Giovanni Manzoni
Giovanni Manzoni b. circa 1950 Civatavecchia, Lazio, Italy is a noted videographer specializing in the avante garde use of YouTube in ham radio homebrew settings. Long noted for his insistence on the use of completely home-made video equipment, Manzoni went so far as to demand that his cameras and recorders only use discrete components — he claimed that integrated circuits “freaked him out.” Manzoni’s collaborators have long been puzzled by his claim that all his videos are filmed “on location.” What he means by this remains unclear, however, in a 1997 interview in QST-Italia, he was quoted as saying “No matter where you go, there you are!”

SolderSmoke Podcast 166: Getting Started in Homebrew Radio

Bench Report: Pete working on Direct Conversion Receivers.
Bill on his 2B and on 20DSB rig, and an M0XPD/Kanga DDS kit, and a 140 watt amp.

GETTING STARTED IN HOMEBREW:
Start simple: Build an oscillator. Make it oscillate!
Gather tools, simple test gear, and books.
Try to understand what you build.
Build a direct conversion receiver.
Don’t fear the toroids!
Be patient. This is not Plug and Play.
Build a DSB transceiver.
Little tips:
Protect variable caps.
Use heat sinks.
Use reverse polarity protection.
Don’t breathe the solder smoke! Ventilate your bench.

SolderSmoke Interview on ICQ Podcast

Colin and Martin of the ICQ Podcast were kind enough to invite me in for an interview. I really enjoyed our talk. We covered a lot of ground, everything from podcast history, to regens and BITXs and Arduinos. I think SolderSmoke podcast listeners will enjoy this. Thanks Martin! Thanks Colin! Here it is:

Part III with Pete Juliano this Saturday

It looks like Pete Juliano, N6QW, and I will be able to do Part III of our discussion of homebrew SSB gear this Saturday. We might start out with ladder filters. Other possible topics include construction practices (shielding, decoupling, the handling of heat, etc), junk-box practices, essential test gear and, time permitting, tube (or, as Grayson would say, “thermatron”) gear. Speaking of which, here are some pictures that Pete sent me of a 20 meter CW rig he is working on.

“Here is a 20 Meter station that I recently got working and hope to have it on the air soon. The Rx is something I cobbled together and it does have a Crystal filter. The Tx is an amalgamation of several Handbook radios – one feature it uses a bandpass tuning network from the oscillator to the final. The screen voltage has a separate regulator. Each unit size is 4 inches high, 4 inches wide and 8 inches long. There is still some work needed for the control and TR.”

Our First Listener: Brad Smith, WA5PSA

I got a nice message yesterday from Brad Smith, WA5PSA. Brad told me that he had listened to both of the Pete Juliano podcasts…TWICE. As a result, he is planning to build a phone rig.

In the message Brad reminded me that he was the source of the very first feedback that Mike, KL7R, and I received about the SolderSmoke podcast. I remember it very well. We had uploaded SolderSmoke#1, and were wondering if ANYONE had listened. Then came this message from Brad (was it an e-mail?) saying that he’d listened to the show AS HE JOGGED THROUGH TULSA, OKLAHOMA. Wow! Tulsa! Our voices from London and Juneau had been heard in ear-buds by a jogger in Tulsa, OK. It was a bit like when you were a kid and you ran into the kitchen to tell your mom that you had just talked to a guy in TULSA. Somehow, that day, Tulsa seemed as exotic as Tokyo.

Thanks Brad! Good luck with the phone rig. Hope to work you on 17.
