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.

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.

Start small – Don’t jump straight into a big SSB transceiver project• .

View rigs as collections of sub-circuits.

Focus on these circuits.

Page 25: The Joys and Sorrows of Building your own Rigs. And some ......Fast Forward to 1993. Dominican Republic. The Michigan Mighty Mite “JOO!”

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.

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.
