Hi Ron,

(per your request)

This old friend, the Tuna Tin, has been mentioned on a few occasions on the net. 

Here’s my relation with this old circuit:

I home-brewed the 1st version of the TT using R.S. coils and passive components. A JAN Crystals FT243 rock on 

7.06 MHz kept the little CW transmitter on frequency and stable on a small 12 VDC wall wart supply. This was my 

first transmitter and it provided ~1/2w into 50 ohms. 

I forwarded the 0.5w cw signal to a junkbox tuner and out my window of a Westbrook apartment to a 40 meter 

end-fed 3/4 wave piece of stranded copper wire. 

Made many CW contacts with my tiny 500 mWTuna Tin, a Heathkit HR-10B receiver and a wire. 😉
