A Vintage Tuna Tin Two!

VINTAGE 1976 TUNA TIN 2 BY WN6KYO

Vintage 1976 Tuna Tin Two

Built by Jack Roblin, WN6KYO, June 1976

The Tuna Tin Two, a QRP 40M Transmitter by Doug DeMaw. QST, May 1976

This classic Tuna Tin Two was built as a project while attending the Amateur Radio Summer school class at Santa Monica High School in California. I was 15 years old when I built this classic little rig. In fact, it was one of the first electronic projects I ever built! What a GREAT project it was too! It helped inspire several others in the class to get their novice licenses. This unique little transmitter, even with its very modest 250 milliwatts output, provided hours of fun and plenty of great contacts during that time.

"The moment I saw the QST cover, I knew I had to build one."

- Jack Roblin, WA6KYO

ORIGINAL QST TUNA TIN 2 COVER

This is the original photograph used on the May 1976 cover of QST.

Special thanks to Ed Hare W1RFI and the ARRL for providing this classic photo!

Click on the cat's face to see a SPECTACULAR enlarged image of the W1FB Tuna Tin 2! Using my Macintosh and PhotoShop, I've cropped and enlarged the TT2 from the original 4.4 Megabyte BMP image that Ed Hare sent me. Thanks Ed for allowing me to do this. The result is fabulous!!!

Cool QRP Cat Zener looks puuuuuuurrrrfectly happy.....no wonder.....I'm sure he enjoyed polishing off the contents of the can!!! hi hi

WDØEME: Here is Clint's wonderful example of an original and vintage Tuna Tin Two, built in 1979! It's still in great shape after all these years. Original TT2's are now extremely RARE so this photo is especially appreciated. If you have one, or know someone who does, please feel free to send us a photo of it. The TT2 Gallery needs more original TT2's.

W9JOP/4 TUNA TIN TWO

W9JOP WORKED ALL STATES - TUNA TIN TWO !!

W9JOP, Bob Chapman of Virginia, is the first US Amateur to earn an ARRL WAS Award with his two TT2's (middle one is for 40M, right "boxed" TT2 for 20M). A great accomplishment!! His antenna is a G5RV at 50 feet. He also uses a superb Collins 51S-1 receiver with his QRPp gear, which also includes the Norcal SMK-1, and a Tick Keyer from Embedded Research. Bob's accomplishment is remarkable because he used only TWO CRYSTALS: 7043 and 14060 KHz. And, I might add, he did it the old fashioned way, and the most FUN and rewarding way: no skeds were set up - " I just waited for the states to cross my Xtal freqs, then POUNCED UPON 'EM!!" Congrats to you Bob - Great work!!
