BITX20 - 7. Building and measuring the "First Mixer"

This is by far the most dreaded part for me.... I don't know why, but i just do not like to wind coils.....
So that is the reason i have been putting it off for so long.... But! i forced myself to do it and.....


TAADAAA!!!!
There are the 1st two trifilar coils. Thank god that was done. Putting in the 4 1n4148 diodes was easy , so now this very small section looks like this....


After this we finally could measure voltages on the last transistor of the vfo part, and that turned out fine.
On to the next part !!!
