Guys: <\/p>\n

I have been catching up on the last few SolderSmoke podcasts after
that little QSO Today diversion. I wonder how many others did the
same thing? I have really enjoyed these recent ‘casts. Lots of
fantastic HB content. Funniest moment was when Bill described his
post-project workshop as looking like the aftermath from an electronic
barfight.<\/p>\n

I took a new ham up on a SOTA activation last year. Then about a
month ago, he said that he wanted to do HF HB. He said he had been
googling and found so much that he didn’t know where to start. I told
him that I’d be interesting in doing a beginner HF HB project with
him.<\/p>\n

I could have pointed him to LBS, et al. I could have pointed him to
the Michigan Mighty Mite. I did neither. I pointed him to:<\/b>http:\/\/web.cecs.pdx.edu\/~<\/b><\/span><\/wbr>campbell\/EMRFD1dot34.pdf<\/b><\/a> Note the name of
the document. I pointed him also to:<\/b><\/span>http:\/\/www.arrl.org\/files\/<\/wbr>file\/Product%20Notes\/chapter_<\/wbr>1.pdf<\/b><\/a> <\/b><\/span>
(Did you guys know that chapter was online and free?) We scaled to 20m and
kitted parts for this. And parts for a 4th transistor PA for serious
QRO. \ud83d\ude42<\/p>\n

Two others joined us building for 40m. Check out the attached photos
of the first 3. The joy of oscillation was experienced by all.<\/p>\n

After testing each oscillator, and borrowing from an article KK7B ran
in CQ VHF, I told each that he had to ID every 10 minutes. Even
though nobody was going to hear these signals a few hundred yards
away. (But it sounds loud on a shortwave portable a few inches away!)
I even wrote out the dots and dashes for a couple of them.<\/p>\n

Next stop: to have everyone find a curbside TV discard, rip out some
parts, and get on 5 meters! Haven’t we gotten it back now, after the
transition to digital TV? \ud83d\ude42<\/p>\n

OK, maybe the next stop is to add some gain stages and experience the
joy of communication. The joy of QSO-ification? The joy of
EM-radiation? \ud83d\ude42<\/p>\n

Best regards,<\/p>\n
