    FM converter (mixer) -- I don't understand

    GoodMoring Sir, ithe value of C14 IS 5nf, and this circuit i take from the book, he explain almost everything but not all, i replace C5 with C23 300pF:smile::smile::smile:THANK YOU...…………….

    FM converter (mixer) -- I don't understand

    Sorry tomi dont understand with V1 having zero output i build the same result, wha do you think maybe wronk circuits? because also in the book they dont say nothing about L4 and C16 see picture, alsoi put the file if you need, i dont know anymore what to do, you have to rename cricut.txt...

    FM converter (mixer) -- I don't understand

    Hello Tom i try to simulate in ltspice, i tune L4 and C16 to 98mhz,? i get this result, is ok? HI Tom, i try to experiment, and what do you think is this mixer good, and result good, output from collector see
