A Little About Me

I've been licensed since 1961 and have never lost interest in the hobby. Amateur Radio is a collection of many sub-hobbies. Whatever you do in your ham career, there's always some facet remaining unexplored. Throughout the years, I've enjoyed HF, VHF, UHF, DXing, AM, SSB, traffic/social nets, RTTY, PSK31, transmitter fox hunting, CW and homebrewing gear.  Building equipment and CW have consistently held my interest.


   The photo on the QSL card was taken during late spring of 1961 for my KN9GDT QSL  A real junior op!
   The middle photo was taken in 1967 by my dad (K9GDU-SK) during a 6m band opening.  Do I look grumpy?
   There is a homebrew dual conversion 10m receiver partially visible on the top shelf.  Real top shelf gear!
   The photo on the right was taken in 2016. I used a FF dSLR for more detail so you can recognize me at a hamfest!

Attention Radio Builders! Do you showcase your homebrew radio equipment on the worldwide web? If so, I would like to include a link to your site. It doesn't matter what you've got: original design or handbook project, solid state or tubes, simple or elaborate. Please tell me about it.

Vintage Radio

vintage radio
   Some time after your 40th birthday, you begin to notice changes. For instance, how your arms gradually become too short to read a book....or a rekindled interest in the playthings of yesteryear....Lionel trains, Hallicrafters shortwave receivers or vintage cars, to name a few. I sure do miss that red 1966 MGB convertible!

Not long ago, these things were considered worthless junk....fodder for the landfill. Many are now considered classic industrial art. Pieces of vintage amateur radio equipment, affectionately called "boatanchors," are no exception.

Check out some of my favorite boatanchors:
