...to the transistor...
...and to myself.. (a little bit younger than the transistor)...
...photo taken some years ago on a field day
To celebrate the event and the "end of the world" :) this week I built an VFO with my age...
...from 73 Magazine, December 1972 (p114). It worked first time, although I just built the VFO part (Q1,Q2,Q3) there's no reason the buffer/amp part wouldn't work either. The design in itself is very interesting on the Q1 bias part, which is provided by Q3 to keep a constant output level.
As always I changed things a little bit, used 2n3904 transistor but almost any other transistor would work, with the exception on the one of the first photo in this post :)
Season greetings!
