“Rig here is homebrew”The Joys and Sorrows of Building your own Rigs.
And some tips for the daring.

Clearly, I had THE KNACK.

Teenage Homebrew Disappointment: The Herring Aid Five -- More on this later….
Fast Forward to 1993. Dominican Republic. The Michigan Mighty Mite “JOO!”
Dominican Republic: Homebrew Transmitter“VXO-Controlled 6 Watter”
Back in Virginia – Barebones Super-Het “Station is homebrew”
Out to the Azores –DOUBLE Sideband
•
17 Meter DSB Fun in the Azores
• “Hey, you are on the wrong sideband OM!17 meter is UPPER sideband.”
I would tell them I was transmitting BOTHsidebands.
I would tell them to hit the LSB button on their rigs and they would hear me just the same.
SINGLE Sideband Transmitter
• Inspired by an article in SPRAT
• Parts from a Dominican Republic Swan 240
• Panel meter from the Crystal Radio Club 1973
• “Hey Bill, something is wrong – you’ve LOSTone of your sidebands!”
Back in the USA – The BITX Transceivers
• Bi-Directional Transceiver• Designed by Farhan VU2ESE• No un-obtanium – Nylon Washer Coils• Homebrew crystal filters• Cheap. Five Bucks.
• I used “Manhattan” style construction.
BITX in a Box (a wood box from Michael’s)
Frequency Readout – Old or New
Other BITX rigs – BITX20, uBITX, DIGI-TIA
Back to my teenage failure…. Herring Aid 5
• Tried again in 2014 (38 years later)• STILL couldn’t do it. • From afar, ZL2DEX spotted something• I had wound the oscillator coil wrong. TWICE! • Shortcomings in the QST article. And errors.• But in 2014 I had more knowledge, books, test gear, AND THE INTERNET.
38 Years Later… I finally got it to work.
Some Tips On Homebrewing….
Start small – Don’t jump straight into a big SSB transceiver project• .
View rigs as collections of sub-circuits.
Focus on these circuits.
Take Shep’s Approach:Strive to UNDERSTAND the circuits you build.
Be patient. This is NOT plug and play radio.
This isn’t easy.
For every moment of joy, there is a tale of woe.
Don’t pull your hair out. Take it easy. Take a break. Take a walk around the block.
Shep’s bad date story.
As you build rigs, also build your library, your workbench and your parts supply (junk box).
• No single book is going to provide all the answers.
Join forces with like-minded builders – near and far.Dex ZL2DEX: Pete Juliano, N6QW
SolderSmoke“I listened to the magic that only comes from a radio that you built yourself.”
In that one sentence Ian Abbot described the feeling that can arise in the midst of a room full of solder smoke,and the reward that awaits those who
build their own gear.
